Why ffmpeg/ffserver does not crop video before streaming ?
23 juin 2023, par LyudmilaI want to stream webcam video to dashboard in Grafana.
I run an ffmpeg command :


/usr/bin/ffmpeg -rtsp_transport tcp -i "rtsp://user:password@IP_camera:554/RVi/1/2" -an -filter:v "crop=192:108:100:100" -c:v libvpx -threads 4 -r 10 http://localhost:5070/feed_webm.ffm


In ffserver.conf :


HTTPPort 5070
HTTPBindAddress 0.0.0.0
CustomLog /var/log/ffserver-access.log

<feed>
 File /tmp/feed_webm.ffm
 FileMaxSize 200M
 ACL allow 127.0.0.1
</feed>

<stream>
 Feed feed_webm.ffm
 Format webm

 NoAudio

 VideoCodec libvpx
 VideoSize 704x576
 VideoFrameRate 8

 AVOptionVideo flags +global_header
 AVOptionVideo qmin 1
 AVOptionVideo qmax 31

 PreRoll 15
 StartSendOnKey
 VideoBitRate 400
</stream>

<stream>
 Format status
</stream>


After that, the stream is visible on the dashboard without сrop.


If I run an ffmpeg command with save at PC, video is recorded and played with crop :


/usr/bin/ffmpeg -rtsp_transport tcp -i "rtsp://user:password@IP_camera:554/RVi/1/2" -an -filter:v "crop=192:108:100:100" -c:v libvpx -threads 4 -r 10 path_to_save/feed.webm

avfilter/buffersrc : fix overriding unknown channel layouts with negotiated one
23 mars 2024, par Marton Balintavfilter/buffersrc : fix overriding unknown channel layouts with negotiated one
Fixes ffplay playback of unknown layouts, when SDL directly supports the audio
format, such as :ffplay -f lavfi anullsrc=cl=2C,aformat=s16
Without the patch, "Channel layout change is not supported" errors are
generated because buffersrc (unknown 2 channel) and buffersink (stereo)
negotiated a stereo layout, but the stereo layout was never stored in the
BufferSourceContext.This fixes a regression of 7251f909721a570726775acf61b2b9c28a950c76, but this
is more of a regression of the avfilter channel layout conversion
