vlm rtsp vod with an anlogue tv card
Posted: 03 Apr 2006 00:31
ive been playing around with vlc and streaming tv from my headless linux box a few weeks.
i can stream a channel per udp without problems with a cli like:
./vlc --color v4l:/dev/video:norm=pal:frequency=783250000:size=640x480:channel=0:adev=/dev/adsp:audio=0 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=9000,ab=192,venc=ffmpeg{keyint=80,hurry-up,vt=800000},deinterlace}:std{access=udp,mux=ts,url=clientip:1234}'
because you are not able to change channels with this kind of setup i tried to setup vlm vod but failed...
cli: ./vlc --color --extraintf telnet -vvvvv
i added a vod in the telnet interface with
new arte vod enabled
and tried different input strings eg.
setup arte input v4l:/dev/video:norm=pal:frequency=471250:size=640x480:channel=0:adev=/dev/adsp:audio=0#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=80,venc=ffmpeg{keyint=80,hurry-up,vt=800000},deinterlace}
dunno about the transcode part but even without it i get two errors about unsupported codecs (one for audio, one for video):
any comments?
