/**
* SECTION:rtsp-client
* @short_description: A client connection state
* @see_also: #GstRTSPServer, #GstRTSPThreadPool
*
* The client object handles the connection with a client for as long as a TCP
* connection is open.
*
* A #GstRTSPClient is created by #GstRTSPServer when a new connection is
* accepted and it inherits the #GstRTSPMountPoints, #GstRTSPSessionPool,
* #GstRTSPAuth and #GstRTSPThreadPool from the server.
*
* The client connection should be configured with the #GstRTSPConnection using
* gst_rtsp_client_set_connection() before it can be attached to a #GMainContext
* using gst_rtsp_client_attach(). From then on the client will handle requests
* on the connection.
*
* Use gst_rtsp_client_session_filter() to iterate or modify all the
* #GstRTSPSession objects managed by the client object.

libs: fix API export/import and 'inconsistent linkage' on MSVC Export rtsp-server library API in headers when we're building the library itself, otherwise import the API from the headers. This fixes linker warnings on Windows when building with MSVC. Fix up some missing config.h includes when building the lib which is needed to get the export api define from config.h https://bugzilla.gnome.org/show_bug.cgi?id=797185

stream: refactor TCP backpressure handling The previous implementation stopped sending TCP messages to all clients when a single one stopped consuming them, which obviously created problems for shared media.

Limit queued TCP data messages to one per stream Before, the watch backlog size in GstRTSPClient was changed dynamically between unlimited and a fixed size, trying to avoid both unlimited memory usage and deadlocks while waiting for place in the queue. (Some of the deadlocks were described in a long comment in handle_request().) In the previous commit, we changed to a fixed backlog size of 100. This is possible, because we now handle RTP/RTCP data messages differently from RTSP request/response messages. The data messages are messages tunneled over TCP. We allow at most one queued data message per stream in GstRTSPClient at a time, and successfully sent data messages are acked by sending a "message-sent" callback from the GstStreamTransport. Until that ack comes, the GstRTSPStream does not call pull_sample() on its appsink, and therefore the streaming thread in the pipeline will not be blocked inside GstRTSPClient, waiting for a place in the queue. pull_sample() is called when we have both an ack and a "new-sample" signal from the appsink. Then, we know there is a buffer to write. RTSP request/response messages are not acked in the same way as data messages. The rest of the 100 places in the queue are used for them. If the queue becomes full of request/response messages, we return an error and close the connection to the client. Change-Id: I275310bc90a219ceb2473c098261acc78be84c97

Client: keep a ref to the session Don't just keep a weak ref to the session objects but use a hard ref. We will be notified when a session is removed from the pool (expired) with the new session-removed signal. Don't automatically close the RTSP connection when all the sessions of a client are removed, a client can continue to operate and it can create a new session if it wants. If you want to remove the client from the server, you have to use gst_rtsp_server_client_filter() now.

/* used to cache the media in the last requested DESCRIBE so that

client: rework setup request a little Cache the media in DESCRIBE based on the longest matching path with the uri that we can find in the mount points. Rework the setup request a little to get the media from the session or from the longest matching path, this way we can derive the control string as everything after the path instead of hardcoding it. Find the stream based on the control string and only open a session when all this can be done.

client: simplify session transport handling link/unlink of the transport in a session was done to keep track of all TCP transports and to send RTP/RTCP data to the streams. We can simplify that by putting all the TCP transports in a hashtable indexed with the channel number. We also don't need to link/unlink the transports when we pause/resume the streams. The same effect is already achieved when we pause/play the media. Indeed, when we pause the media, the transport is removed from the media and the callbacks will not be called anymore.

Limit queued TCP data messages to one per stream Before, the watch backlog size in GstRTSPClient was changed dynamically between unlimited and a fixed size, trying to avoid both unlimited memory usage and deadlocks while waiting for place in the queue. (Some of the deadlocks were described in a long comment in handle_request().) In the previous commit, we changed to a fixed backlog size of 100. This is possible, because we now handle RTP/RTCP data messages differently from RTSP request/response messages. The data messages are messages tunneled over TCP. We allow at most one queued data message per stream in GstRTSPClient at a time, and successfully sent data messages are acked by sending a "message-sent" callback from the GstStreamTransport. Until that ack comes, the GstRTSPStream does not call pull_sample() on its appsink, and therefore the streaming thread in the pipeline will not be blocked inside GstRTSPClient, waiting for a place in the queue. pull_sample() is called when we have both an ack and a "new-sample" signal from the appsink. Then, we know there is a buffer to write. RTSP request/response messages are not acked in the same way as data messages. The rest of the 100 places in the queue are used for them. If the queue becomes full of request/response messages, we return an error and close the connection to the client. Change-Id: I275310bc90a219ceb2473c098261acc78be84c97

client: Add drop-backlog property When we have too many messages queued for a client (currently hardcoded to 100) we overflow and drop the messages.

Limit queued TCP data messages to one per stream Before, the watch backlog size in GstRTSPClient was changed dynamically between unlimited and a fixed size, trying to avoid both unlimited memory usage and deadlocks while waiting for place in the queue. (Some of the deadlocks were described in a long comment in handle_request().) In the previous commit, we changed to a fixed backlog size of 100. This is possible, because we now handle RTP/RTCP data messages differently from RTSP request/response messages. The data messages are messages tunneled over TCP. We allow at most one queued data message per stream in GstRTSPClient at a time, and successfully sent data messages are acked by sending a "message-sent" callback from the GstStreamTransport. Until that ack comes, the GstRTSPStream does not call pull_sample() on its appsink, and therefore the streaming thread in the pipeline will not be blocked inside GstRTSPClient, waiting for a place in the queue. pull_sample() is called when we have both an ack and a "new-sample" signal from the appsink. Then, we know there is a buffer to write. RTSP request/response messages are not acked in the same way as data messages. The rest of the 100 places in the queue are used for them. If the queue becomes full of request/response messages, we return an error and close the connection to the client. Change-Id: I275310bc90a219ceb2473c098261acc78be84c97

The GstMediaBin object has a handle to a bin with elements and to a list of GstMediaStream objects that this bin produces. Add GstMediaMapper that can map url mountpoints to GstMediaFactory objects along with methods to register and remove those mappings. Add methods and a property to GstRTSPServer to manage the GstMediaMapper object used by the server instance. Modify the example application so that it shows how to create custom pipelines attached to a specific mount point. Various misc cleanps.

Limit queued TCP data messages to one per stream Before, the watch backlog size in GstRTSPClient was changed dynamically between unlimited and a fixed size, trying to avoid both unlimited memory usage and deadlocks while waiting for place in the queue. (Some of the deadlocks were described in a long comment in handle_request().) In the previous commit, we changed to a fixed backlog size of 100. This is possible, because we now handle RTP/RTCP data messages differently from RTSP request/response messages. The data messages are messages tunneled over TCP. We allow at most one queued data message per stream in GstRTSPClient at a time, and successfully sent data messages are acked by sending a "message-sent" callback from the GstStreamTransport. Until that ack comes, the GstRTSPStream does not call pull_sample() on its appsink, and therefore the streaming thread in the pipeline will not be blocked inside GstRTSPClient, waiting for a place in the queue. pull_sample() is called when we have both an ack and a "new-sample" signal from the appsink. Then, we know there is a buffer to write. RTSP request/response messages are not acked in the same way as data messages. The rest of the 100 places in the queue are used for them. If the queue becomes full of request/response messages, we return an error and close the connection to the client. Change-Id: I275310bc90a219ceb2473c098261acc78be84c97

Limit queued TCP data messages to one per stream Before, the watch backlog size in GstRTSPClient was changed dynamically between unlimited and a fixed size, trying to avoid both unlimited memory usage and deadlocks while waiting for place in the queue. (Some of the deadlocks were described in a long comment in handle_request().) In the previous commit, we changed to a fixed backlog size of 100. This is possible, because we now handle RTP/RTCP data messages differently from RTSP request/response messages. The data messages are messages tunneled over TCP. We allow at most one queued data message per stream in GstRTSPClient at a time, and successfully sent data messages are acked by sending a "message-sent" callback from the GstStreamTransport. Until that ack comes, the GstRTSPStream does not call pull_sample() on its appsink, and therefore the streaming thread in the pipeline will not be blocked inside GstRTSPClient, waiting for a place in the queue. pull_sample() is called when we have both an ack and a "new-sample" signal from the appsink. Then, we know there is a buffer to write. RTSP request/response messages are not acked in the same way as data messages. The rest of the 100 places in the queue are used for them. If the queue becomes full of request/response messages, we return an error and close the connection to the client. Change-Id: I275310bc90a219ceb2473c098261acc78be84c97

rtsp-client: cleanup transports during TEARDOWN When tunneling RTP over RTSP the stream transports are stored in a hash table in the GstRTSPClientPrivate struct. They are used for, among other things, mapping channel id to stream transports when receiving data from the client. The stream tranports are created and added to the hash table in handle_setup_request(), but unfortuately they are not removed in handle_teardown_request(). This means that if the client sends data on the RTSP connection after it has sent the TEARDOWN, which is often the case when audio backchannel is enabled, handle_data() will still be able to map the channel to a session transport and pass the data along to it. Which eventually leads to a failing assert in gst_rtsp_stream_recv_rtp() because the stream is no longer joined to a bin. We avoid this by removing the stream transports from the hash table when we handle the TEARDOWN request. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server/-/merge_requests/184>

rtsp-client: Lock shared media For shared media we got race conditions. Concurrently rtsp clients might suspend or unsuspend the shared media and thus change the state without the clients expecting that. By introducing a lock that can be taken by callers such as rtsp_client one can force rtsp clients calling, eg. PLAY, SETUP and that uses shared media, to handle the media sequentially thus allowing one client to finish its rtsp call before another client calls on the same media. https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server/issues/86 Fixes #86

For all other clocks we at least signal that it's the local sender clock. This allows receivers to know which clock was used to generate the media and its RTP timestamps. Receivers can then implement network synchronization, either absolute or at least relative by getting the sender clock rate directly via NTP/PTP instead of estimating it from RTP timestamps and packet receive times. https://bugzilla.gnome.org/show_bug.cgi?id=760005

session-media: let the session-media make the RTPInfo Add method to create the RTPInfo for a stream-transport. Add method to create the RTPInfo for all stream-transports in a session-media.

/* grab RTPInfo from the media now */
rtsp-client: RTP Info when completed_sender Change condition that should be fulfilled regarding RTPInfo. Replace !gst_rtsp_media_is_receive_only with gst_rtsp_media_has_completed_sender. It is more correct to actually look for a sender pipeline that is complete. Only then a RTPInfo should exist. gst_rtsp_media_is_receive_only gives different answears depending on state of server. If Describe is called wth URL+options for backchannel SDP will give only audio and only backchannel a=sendonly If Describe is called on URL+options that gives both audio and video direction from server to client, pipelines are created. Thus receive_only will return false, even though Setup only would setup backchannel. RTP-Info is only for outgoing streams. Thus one should look if outgoing streams are complete.

When first connecting an IPV4 client, then an IPV6 client, multiudpsink errored out, released the IPV4 socket, then crashed when trying to send a message on NULL nevertheless, that is however a separate issue. This could probably be fixed by handling the setting of sockets in multiudpsink after it has started, that will however be a much more significant effort. For now, this commit simply partially reverts the behaviour of rtsp-stream: it will continue to only create the udpsinks when needed, as was the case since the patches were merged, it will however when creating them, always allocate both sockets and set them on the sink before it starts, as was the case prior to the patches. Transport configuration will only error out if the allocation of UDP sockets fails for the actual client's family, this also downgrades the GST_ERRORs in alloc_ports_one_family to GST_WARNINGs, as failing to allocate is no longer necessarily fatal. https://bugzilla.gnome.org/show_bug.cgi?id=796875

stream: Added a list of multicast client addresses When media is shared, the same media stream can be sent to multiple multicast groups. Currently, there is no API to retrieve multicast addresses from the stream. When calling gst_rtsp_stream_get_multicast_address() function, only the first multicast address is returned. With this patch, each multicast destination requested in SETUP will be stored in an internal list (call to gst_rtsp_stream_add_multicast_client_address()). The list of multicast groups requested by the clients can be retrieved by calling gst_rtsp_stream_get_multicast_client_addresses(). There still exist some problems with the current implementation in the multicast case: 1) The receiving part is currently only configured with regard to the first multicast client (see https://bugzilla.gnome.org/show_bug.cgi?id=796917). 2) Secondly, of security reasons, some constraints should be put on the requested multicast destinations (see https://bugzilla.gnome.org/show_bug.cgi?id=796916).

rtsp: massive refactoring Make GObjects from the remaining simple structures. Remove GstRTSPSessionStream, it's not needed. Rename GstRTSPMediaStream -> GstRTSPStream: It is shorter Rename GstRTSPMediaTrans -> GstRTSPStreamTransport: It describes how a GstRTSPStream should be transported to a client. Rename GstRTSPMediaFactory::get_element -> create_element because that more accurately describes what it does. Make nice methods instead of poking in the structures. Move some methods inside the relevant object source code. Use GPtrArray to store objects instead of plain arrays, it is more natural and allows us to more easily clean up. Move the allocation of udp ports to the Stream object. The Stream object contains the elements needed to stream the media to a client. Improve the prepare and unprepare methods. Unprepare should now undo everything prepare did. Improve also async unprepare when doing EOS on shutdown. Make sure we always unprepare correctly.

The GstMediaBin object has a handle to a bin with elements and to a list of GstMediaStream objects that this bin produces. Add GstMediaMapper that can map url mountpoints to GstMediaFactory objects along with methods to register and remove those mappings. Add methods and a property to GstRTSPServer to manage the GstMediaMapper object used by the server instance. Modify the example application so that it shows how to create custom pipelines attached to a specific mount point. Various misc cleanps.

Cleanup of sessions and more Fix the refcounting of media and sessions in the client. Properly clean up the session data when the client performs a teardown. Add Server header to responses. Allow for multiple uri setups in one session. Add Range header to the PLAY response and add the range attribute to the SDP message. Fix the session pool remove method, it used the wrong key in the hashtable. Also give the ownership of the sessionid to the session object.

Rename GstRTSPMediaFactory::get_element -> create_element because that more accurately describes what it does. Make nice methods instead of poking in the structures. Move some methods inside the relevant object source code. Use GPtrArray to store objects instead of plain arrays, it is more natural and allows us to more easily clean up. Move the allocation of udp ports to the Stream object. The Stream object contains the elements needed to stream the media to a client. Improve the prepare and unprepare methods. Unprepare should now undo everything prepare did. Improve also async unprepare when doing EOS on shutdown. Make sure we always unprepare correctly.

Limit queued TCP data messages to one per stream Before, the watch backlog size in GstRTSPClient was changed dynamically between unlimited and a fixed size, trying to avoid both unlimited memory usage and deadlocks while waiting for place in the queue. (Some of the deadlocks were described in a long comment in handle_request().) In the previous commit, we changed to a fixed backlog size of 100. This is possible, because we now handle RTP/RTCP data messages differently from RTSP request/response messages. The data messages are messages tunneled over TCP. We allow at most one queued data message per stream in GstRTSPClient at a time, and successfully sent data messages are acked by sending a "message-sent" callback from the GstStreamTransport. Until that ack comes, the GstRTSPStream does not call pull_sample() on its appsink, and therefore the streaming thread in the pipeline will not be blocked inside GstRTSPClient, waiting for a place in the queue. pull_sample() is called when we have both an ack and a "new-sample" signal from the appsink. Then, we know there is a buffer to write. RTSP request/response messages are not acked in the same way as data messages. The rest of the 100 places in the queue are used for them. If the queue becomes full of request/response messages, we return an error and close the connection to the client. Change-Id: I275310bc90a219ceb2473c098261acc78be84c97

Start support for RTSP 2.0 This adds basic support for new 2.0 features, though the protocol is subposdely backward incompatible, most semantics are the sames. This commit adds: - features: * version negotiation * pipelined requests support * Media-Properties support * Accept-Ranges support - APIs: * gst_rtsp_media_seekable The RTSP methods that have been removed when using 2.0 now return BAD_REQUEST. https://bugzilla.gnome.org/show_bug.cgi?id=781446

rtsp-client: Lock shared media For shared media we got race conditions. Concurrently rtsp clients might suspend or unsuspend the shared media and thus change the state without the clients expecting that. By introducing a lock that can be taken by callers such as rtsp_client one can force rtsp clients calling, eg. PLAY, SETUP and that uses shared media, to handle the media sequentially thus allowing one client to finish its rtsp call before another client calls on the same media. https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server/issues/86 Fixes #86

Make a mount point of "/" work correctly. As far as I can tell, this is neither explicitly allowed nor forbidden by RFC 7826. Meanwhile, URLs such as rtsp://<IP>:554 or rtsp://<IP>:554/ are in use in the wild (presumably with non-GStreamer servers). GStreamer's prior behavior was confusing, in that gst_rtsp_mount_points_add_factory() would appear to accept a mount path of "" or "/", but later connection attempts would fail with a "media not found" error. This commit makes a mount path of "/" work for either form of URL, while an empty mount path ("") is rejected and logs a warning.

rtsp-client: Lock shared media For shared media we got race conditions. Concurrently rtsp clients might suspend or unsuspend the shared media and thus change the state without the clients expecting that. By introducing a lock that can be taken by callers such as rtsp_client one can force rtsp clients calling, eg. PLAY, SETUP and that uses shared media, to handle the media sequentially thus allowing one client to finish its rtsp call before another client calls on the same media. https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server/issues/86 Fixes #86

Make a mount point of "/" work correctly. As far as I can tell, this is neither explicitly allowed nor forbidden by RFC 7826. Meanwhile, URLs such as rtsp://<IP>:554 or rtsp://<IP>:554/ are in use in the wild (presumably with non-GStreamer servers). GStreamer's prior behavior was confusing, in that gst_rtsp_mount_points_add_factory() would appear to accept a mount path of "" or "/", but later connection attempts would fail with a "media not found" error. This commit makes a mount path of "/" work for either form of URL, while an empty mount path ("") is rejected and logs a warning.

rtsp-client: Lock shared media For shared media we got race conditions. Concurrently rtsp clients might suspend or unsuspend the shared media and thus change the state without the clients expecting that. By introducing a lock that can be taken by callers such as rtsp_client one can force rtsp clients calling, eg. PLAY, SETUP and that uses shared media, to handle the media sequentially thus allowing one client to finish its rtsp call before another client calls on the same media. https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server/issues/86 Fixes #86

Add methods and a property to GstRTSPServer to manage the GstMediaMapper object used by the server instance. Modify the example application so that it shows how to create custom pipelines attached to a specific mount point. Various misc cleanps.

rtsp-client: Lock shared media For shared media we got race conditions. Concurrently rtsp clients might suspend or unsuspend the shared media and thus change the state without the clients expecting that. By introducing a lock that can be taken by callers such as rtsp_client one can force rtsp clients calling, eg. PLAY, SETUP and that uses shared media, to handle the media sequentially thus allowing one client to finish its rtsp call before another client calls on the same media. https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server/issues/86 Fixes #86

We can simplify that by putting all the TCP transports in a hashtable indexed with the channel number. We also don't need to link/unlink the transports when we pause/resume the streams. The same effect is already achieved when we pause/play the media. Indeed, when we pause the media, the transport is removed from the media and the callbacks will not be called anymore.

Limit queued TCP data messages to one per stream Before, the watch backlog size in GstRTSPClient was changed dynamically between unlimited and a fixed size, trying to avoid both unlimited memory usage and deadlocks while waiting for place in the queue. (Some of the deadlocks were described in a long comment in handle_request().) In the previous commit, we changed to a fixed backlog size of 100. This is possible, because we now handle RTP/RTCP data messages differently from RTSP request/response messages. The data messages are messages tunneled over TCP. We allow at most one queued data message per stream in GstRTSPClient at a time, and successfully sent data messages are acked by sending a "message-sent" callback from the GstStreamTransport. Until that ack comes, the GstRTSPStream does not call pull_sample() on its appsink, and therefore the streaming thread in the pipeline will not be blocked inside GstRTSPClient, waiting for a place in the queue. pull_sample() is called when we have both an ack and a "new-sample" signal from the appsink. Then, we know there is a buffer to write. RTSP request/response messages are not acked in the same way as data messages. The rest of the 100 places in the queue are used for them. If the queue becomes full of request/response messages, we return an error and close the connection to the client. Change-Id: I275310bc90a219ceb2473c098261acc78be84c97
