• ffserver : translate cropped video

  26 janvier 2021, par Michael O.

  I'm getting the h264 video from IP camera. I need to crop it and retranslate with ffserver. Here is the command ffmpeg to get a stream :

  


  ffmpeg -rtsp_transport tcp -i "rtsp://admin:@192.168.88.10:554/channel=1&stream=0.sdp" -filter:v "crop=400:250:800:1045" -vcodec h264 tmp.mp4


  


  It works fine and I get the cropped video in the file tmp.mp4.

  


  Here are the ffserver settings :

  


  <feed>&#xA;File /tmp/feed1.ffm&#xA;FileMaxSize 200M&#xA;Launch ffmpeg -rtsp_transport tcp -i "rtsp://admin:@192.168.88.10:554/channel=1&amp;stream=0.sdp" -filter:v "crop=400:250:800:1045" -vcodec h264&#xA;</feed>&#xA;<stream>&#xA;Feed feed1.ffm&#xA;Format mjpeg&#xA;VideoBitRate 1000&#xA;VideoBufferSize 400&#xA;VideoFrameRate 17&#xA;VideoSize 400x250&#xA;VideoGopSize 10&#xA;NoAudio&#xA;Preroll 5&#xA;NoDefaults&#xA;</stream>&#xA;

  


  Trying to launch ffserver :

  


  $ ffserver -loglevel debug -d -f /etc/ffserver.conf

  There is the line :

  


  Codecs do not match for stream 0


  


  every time when I try to launch it. I tried various video formats : mpjpeg, avi, mpeg, flv, mp4, webm, and the result is the same. How can I successfully launch ffserver ?
