Setting FPS when using FFMPEG as encoder option

Since VLC does not natively support reducing framerate (say I have a video at 25fps and want to stream 3gp at 7 fps)...

I am trying to use the "venc=ffmpeg" option. When I do, VLC accepts it, so i know its not a problem. but it does not look as though it is passing in the needed fps paramater, and makes my rtsp stream the full 25fps or so.

eg:

Code: Select all

vlc "c:\pmp\ffmpeg\9c42c12c-8879-4b9e-87ec-1b90d46b9927.avi" :sout=#transcode{width=128,height=96,vcodec=H263,venc=ffmpeg,vb=60000,fps=7,acodec=mp4a,ab=24,channels=1,samplerate=11025}:rtp{dst=127.0.0.1,port=501,port-audio=11002,port-video=11000,sdp=rtsp://192.168.2.205:501/4923fe00-1265-4bd7-b8b7-4c524dd7f1b8.3gp}}
No if i do ffmpeg manually, and feed that to VLC, all is fine...


Im sure im just missing something stupid here. Maybe someone can point it for me?

Thanks !!!!!

Low FPS playback and encoding has some issues. And all encoders won't accept low FPS value (at least MPEG-2 encoder has issues).
