How to turn off audio

[doriansari]

Hi,

I'm trying to make a video-only recording on 0.9.8a running on Fedora 10. My command line is

cvlc v4l2:// :v4l2-adev=/dev/audio :v4l2-dev=/dev/video0 :v4l2-fps=15.0 :v4l2-width=320 :v4l2-height=240 --width=320 --height=240 -vvv --no-audio --sout '#duplicate{dst=display,dst="transcode{vcodec=mp4v,venc=ffmpeg{keyint=15},vb=128,fps=15,width=320,height=240}:rtp{mux=ts,dst=10.4.4.125,port=4470,sdp=rtsp://192.168.1.130:8085/test.sdp}"}'

However here is a portion of my output:

[00000519] main audio output warning: audio drift is too big (123387), dropping buffer
[00000519] main audio output warning: audio drift is too big (123371), dropping buffer
[00000519] main audio output warning: audio drift is too big (123321), dropping buffer
[00000519] main audio output warning: audio drift is too big (123235), dropping buffer

[00000519] main audio output warning: audio drift is too big (120613), dropping buffer
[00000519] main audio output warning: audio drift is too big (120545), dropping buffer
[00000519] main audio output debug: audio output is starving (30190), playing silence
[00000519] main audio output debug: audio output is starving (45927), playing silence

Can you tell me what is the proper way to turn off the audio mux'ing? I have a feeling this audio bug is interfering with sdp file generation because the sdp file is:

v=0
o=- 14792903424208527185 14792903424208527185 IN IP4 vlc
s=Unnamed
i=N/A
c=IN IP4 10.4.4.125
t=0 0
a=tool:vlc 0.9.8a
a=recvonly
a=type:broadcast
a=charset:UTF-8
m=video 4470 RTP/AVP 33
b=RR:0
a=rtpmap:33 MP2T/90000

is missing a lot of important information like the MP4 VOL header "fmtp."

Thanks that worked!

Can you also give me suggestions as to how to remove pixellation & mosaic'ing when the video bitrate is 128kbps (and the imagesize is QVGA (320x240)?

Thanks
