• Streaming WebM with ffmpeg over UDP doesn't work with audio

  28 avril 2014, par omgodie

  I’m trying to stream a webcam video and audio as WebM via udp over the ffmpeg command line tool. (ffmpeg is build correctly and all libraries are included)

  The stream is initiated with :

  ffmpeg -f dshow -i video="Logitech HD Pro Webcam C910":audio="Mikrofon (USB-Audogerät)" -f webm udp://localhost:11100

  and i try to playback the file on the same computer with :

  ffplay udp://localhost:11100

  Streaming Video AND audio doesn’t work. I get the following error message in ffplay :

  udp://localhost:11100: End of file 0KB vq=    0KB sq=    0B f=0/0
  
  nan    :  0.000 fd=   0 aq=    0KB vq=    0KB sq=    0B f=0/0

  If i just stream the video

  ffmpeg -f dshow -i video="Logitech HD Pro Webcam C910" -f webm udp://localhost:11100

  I receive the video with ffplay.

  What do i have to do to stream/receive audio correctly ?

  I’m trying this way with the command line to reproduce a way with using libav in a C project if this is of interest...
