I hacked rist_ts and rist_rx changes to test quickly Not sure if I should remove the changes completely or add new programs |

This depends on https://github.com/funman/bitstream/tree/srt |
Use default values from the SRT draft
Here's what libsrt source has to say: // control info field should be none // but "writev" does not allow this m_PacketVector[PV_DATA].set((void*)&m_extra_pad, 4);
Ignore reply if type is unexpected (e.g. reply to an earlier message) Reinitialize if not connected after 3s
This can break up scheduling for some reason We needed it for dejitter, we don't need it anymore
Make upipe_srt_handshake_handle_hs_listener_conclusion() throw source end in case of failure Most notable error case is a wrong password Throwing source end will let application restart pipeline and not leave a half-connected state.

srtr: Delete drift_rate before outputting uref
Fixes getting stuck with old caller (cherry picked from commit 453f3958e0982043b4c4b9508b8cbcae9ffe8986) Signed-off-by: Rafaël Carré <[email protected]>
srt_tx: use this event to "disconnect" from remote peer
We already check for dst_socket_id in upipe_srt_handshake_input()
if we are caller the uri never changes
Ignore handshakes with different socket id when we're already connected. Do not send a reply, as it would reach the wrong remote. keepalive will trigger and restart after 10s if needed Second case: if we do not received the expected induction type, trigger disconnection. Since we sent a rejection message we expect a new socket anyway.

(cherry picked from commit 5cac22d) Signed-off-by: Rafaël Carré <[email protected]>
This makes sure for example that keepalives coming from srt receiver do not leave to an old remote If handshake did not succeed we do not restart the pipeline, so udp sink would still have a destination set Since srt receiver pipe is still running it keeps sending keepalives

What is the status of this SRT implementation? Intended to be mainlined at some point? Experimental? |
|
Hi Kyle,
I have been using this implementation in production for nearly a year now
without major issues and interoperating with various libsrt library
versions.
Most of the recent work has been around a few edge cases for rogue callers.
The intention is to mainline it after some review. It's worth saying it's
hard to unit test and also fuzz a complex protocol like SRT so that's a
missing piece of work.
Regards,
Kieran Kunhya
