Original commit message from CVS: * gst/tcp/README: * gst/tcp/gstmultifdsink.c: (gst_multi_fd_sink_init), (gst_multi_fd_sink_remove_client_link), (gst_multi_fd_sink_client_queue_caps), (gst_multi_fd_sink_client_queue_buffer), (gst_multi_fd_sink_handle_client_write), (gst_multi_fd_sink_render): * gst/tcp/gstmultifdsink.h: make multifdsink properly deal with streamheader: - streamheader is taken from caps - buffers marked with IN_CAPS are not sent - streamheaders are sent, on connection, from the caps of the buffer where the client gets positioned to - further streamheader changes are done every time the client will receive a buffer with different caps * tests/check/elements/multifdsink.c: (GST_START_TEST), (gst_multifdsink_create_streamheader): add tests for this

TESTS
|
|
-----
|
|
Use these tests to test functionality of the various tcp plugins
|
|
|
|
* server: nc -l -p 3000
|
|
client: nc localhost 3000
|
|
everything you type in the server is shown on the client

multifdsink
|
|
-----------
|
|
- operation:
|
|
- client fd gets added when "add" signal gets emitted on multifdsink
|
|
- signal handler creates a GstTCPClient structure, adds it to ->clients,
|
|
and adds the fd to ->fd_hash, then emits client-added
|
|
- client
|
|
|
|
- when a buffer comes in:
|
|
- the _render vmethod puts the buffer on the global queue
|
|
- and increases bytes_to_serve
|
|
- (currently it sets streamheaders, but since this is treated globally
|
|
this is wrong - clients can be at different positions in the stream)
|
|
|
|
- when a client issues a write (ie requests data):
|
|
- when using GDP, if no caps sent yet, send caps first, then set caps_sent
|
|
- if streamheader buffers, and we haven't sent yet to this client,
|
|
send current streamheader buffers, then set streamheader_sent
|
|
- send out buffers
