VLM. Problem with option parameter.

[Dmitry.Ananyev]

Hi to all!

I have a problem with video stream through VLM. It running at Ubuntu 12.4 server x64.

This command work fine, when I run it in debug mode:
cvlc -vvv rtsp://10.5.4.21:554/h264 --sout-mux-caching=5000 --sout '#transcode{vcodec=FLV1,vb=1024,acodec=mp3,ab=128,channels=1,samplerate=44100}:standard{access=http,mux=flv,dst=0.0.0.0:8089/stream.flv}'
video and sound work's fine.

but when i run it in vlm mode, work only sound, w\o video. What's wrong in my config file?

new webcam1 broadcast enabled

setup webcam1 input rtsp://10.5.4.21:554/h264
setup webcam1 option mux-caching=5000
setup webcam1 output #transcode{vcodec=FLV1,vb=1024,acodec=mp3,ab=128,channels=1,samplerate=44100}:standard{access=http,mux=flv,dst=0.0.0.0:8089/stream.flv}

control webcam1 play

May be you ask me, how to debug stream in vlm mode?

Thanks a lot!
Sorry for my English.

i try to run it in vlm console:
It doesn't work, because: cannot add a new stream (unsupported while muxing to this format). You can try increasing sout-mux-caching value

Can anybody help?
How use option "mux-caching" correctly?

[Dmitry.Ananyev]

Resolved.
VLM option parameters stored here: /etc/default/vlcd
VLC_EXTRA_OPTS="--mux-caching=5000"
