1e29c5d52a rtmp2: Set connect args like libavformat does
To improve our compatibility. Critically, a server might elide data for
codecs we don't advertise.

2ad3aab1d4 rtmp2: Add support for AGGREGATE messages
They're multiple frames (tags) of FLV data wrapped into a message.

f3d6026ad2 rtmp2src: Answer scheduling query
Just like for rtmpsrc, we must inform downstream that we are a
sequential (i.e. don't do random access efficiently) and
bandwith-limited (i.e. might need buffering downstream) element

Fixes buffering issues with playbin3

rtmp2: Avoid a deadlock when getting stats
We need to do this without holding the lock as the `g_async_queue_pop`
waits on the loop thread to deliver the stats. The loop thread might
attempt to take the lock as well, leading to a deadlock.

Taking a reference to the connection should be enough to keep this
safe.

7f5347a664 rtmp2src: Add idle-timeout property
Add new property to signalling that there is no incoming data
from peer. This can be useful if users want to stop the streaming
when the connection is alive but no packet is arriving.

rtmp2: Allow setting flash-version
In case the application has to deal with fussy servers. User agent
sniffing is so last decade.

Adds a property to set the Flash version on both the sink and the src.
The default stays the same (IIRC, Flash plugin for Linux from 2009).

rtmp2: Expose connection stats as property

retrieve them afterwards.

rtmp2: Add gst_rtmp_connection_get_stats and _get_null_stats
The former uses a thread-safe way of getting statistics from the
connection without having to protect the fields with a lock.

The latter produces a zeroed statistics structure for use when no
connection exists.

63ec837824 rtmp2: Handle outgoing set chunk/window size properly
Apply outgoing sizes only after writing the chunk to the peer. This is
important particularly for the set chunk size and allows exposing it
without threading issues.

a566461294 rtmp2: Chunk messages as buffers in loop thread
Move output chunking from gst_rtmp_connection_queue_message into
gst_rtmp_connection_start_write, which effectively moves it from the
streaming thread into the loop thread.

This allows us to handle the outgoing chunk-size message (which is
generated by changing the future chunk-size property) properly, which
could come from any other thread.

b03780233e rtmp2: Add gst_rtmp_chunk_stream_serialize_all
Serializes an RTMP message into a series of chunks, all in one buffer.

Similar to what gst_rtmp_connection_queue_message does to serialize
into a GByteArray.

cb7f0c4be7 rtmp2: Add gst_rtmp_output_stream_write_all_buffer_async
Similar to gst_rtmp_output_stream_write_all_bytes_async, but takes a
GstBuffer instead of a GBytes. It can also return the number of bytes
written, which might be lower in case of an error.

14fd7e0884 rtmp2: Lock self->lock before OBJECT_LOCK
OBJECT_LOCK is used to protect property access only. self->lock is
used to access the RtmpConnection, mostly between the streaming thread
and the loop thread.

To avoid deadlocks involving these two locks, we obey a lock order:
If both self->lock and OBJECT_LOCK are needed, self->lock must be locked
first. Clarify this.

rtmp2: Fix NULL check in gst_rtmp_meta_transform
Coverity rightly complains that checking a pointer for NULL after
dereferencing it is pointless.

Remove the check, and to be safe, assert that gst_buffer_add_meta
returns non-NULL.

rtmp2: Check for missing GstRtmpMeta
