std_compliance flags not forwarded to rtp muxer for rtsp output

Reported by: Tristan Matthews Owned by:
Priority: normal Component: avformat
Version: git-master Keywords: rtsp rtp vp9
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

Using master b591329c3afe445c45eaecadd5fe3b80a837ee2f

To reproduce:

./ffmpeg -y  -re -i ~/Videos/akiyo_cif.y4m -c:v libvpx-vp9 -deadline realtime -an -strict -2 -f  rtsp rtsp://my-rtsp-server:8554/stream-xyz

[RTP muxer @ 0x556dcaac6d20] Packetizing VP9 is experimental and its specification is still in draft state. Please set -strict experimental in order to enable it.
Could not write header for output file #0 (incorrect codec parameters ?): Experimental feature
Error initializing output stream 0:0 -- 

whereas

./ffmpeg -y  -re -i ~/Videos/akiyo_cif.y4m -c:v libvpx-vp9 -deadline realtime -an -strict -2 -f  rtp /dev/null

works fine.

Is there a workaround?

Is the packetization still experimental?

Replying to cehoyos:

Yes: https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/rtpenc.c#L215
The issue is that you can't force it to accept the relaxed experimental flag (from the CLI in any case).

Oh if you're asking is the "VP9 packetization spec still experimental", yes I believe so: https://datatracker.ietf.org/doc/draft-ietf-payload-vp9/
