• Getting either incorrect output resolution or FPS from ffmpeg

  5 novembre 2011, par Adam

  I am capturing an RTSP stream from a security camera, and transcoding it for (live streaming) to iphone, using OSX as the encoding platform.
  I have it working correctly, and Im tuning it.
  However, it seems that it is not outputting the requested resolution. This is my script

  /Applications/SecurityCamera/openRTSP -v -c -t rtsp://10.0.1.118/ch1-s1 | \
  
      /Applications/SecurityCamera/ffmpeg \

      -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 \
  
      -aspect 960:640 -r 10 -g 10 -async 2 -\
  
      |/Applications/SecurityCamera/mediastreamsegmenter -b http://localhost:8080/\
  
        -f /Library/WebServer/Documents/ -i stream.m3u8 -t 10 -s 4 -D

  This is the status report :

  Input #0, h264, from 'pipe:':
  
  
  
    Duration: N/A, bitrate: N/A
  
    Stream #0.0: Video: h264, yuv420p, 1600x1200, 10 fps, 10 tbr, 1200k tbn, 20 tbc

  Stream mapping:
  
    Stream #0.0 -> #0.0

  You can see that its working, but it is outputting 1600x1200 for some reason. (possibly -vcodec copy copies all codec parameters, not just the codec type ?)

  If I change the -vcodec copy to -vcodec libx264 then I get the correct status report (stating 960x640, correct), but the streaming switches to 2 FPS (why ? Im forcing both input and output !) and it halts after 54 frames (see output below)
