hi all,
i stream from an acquisition card :
vlc v4l:/dev/video1:norm=pal:frequency=128250:size=320x240:channel=0:adev=/dev/dsp2:audio=0 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,venc=ffmpeg{keyint=80,hurry-up,vt=800000},deinterlace}:std{access=udp,mux=ts,url=192.168.151.36:1234}' --ttl 12
VLC media player 0.8.4a Janus
Remote control interface initialized, `h' for help
status change: ( New input: v4l:/dev/video1:norm=pal:frequency=128250:size=320x240:channel=0:adev=/dev/dsp2:audio=0 )
status change: ( audio volume: 256 )
status change: ( play state: 1 )

and relayed the streaming by another pc:
# vlc udp:@1234 --sout '#std{access=http,mux=asf,url=:8080}'

[00000234] main private: creating httpd
status change: ( New input: udp:@1234 )
status change: ( audio volume: 256 )

then read the streaning by vlc player,but it doesn't work,the error message:

why? thanks

What happens if you change the 'repeater' mux to ts instead of asf?

What happens if you change the 'repeater' mux to ts instead of asf?

it will be ok of vlc , but the streaming can't be read by mediaplayer, my client player is mediaplayer.

What if you remove 'mux' from the repeater?

remove the "mux", the repeater does'not work,

when i stream from acquisition card by http but not udp,and relay by http, all is ok.
#vlc v4l:/dev/video1:norm=pal:frequency=128250:size=320x240:channel=0:adev=/dev/dsp2:audio=0 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,venc=ffmpeg{keyint=80,hurry-up,vt=800000},deinterlace}:std{access=http,mux=ts,url=:1234}' --ttl 12
# vlc http:192.168.151.88:1234 --sout '#std{access=http,mux=asf,url=:8080}'

but there is a flaw, if the streaming from the acquisition card is stop, the "repeater" will stop too, when the acquisition card work again, the command must be run again on the "repeater" so the streaming can be relayed afresh. if relay the streaming by udp(streaming from card use udp too), when the card work agian, the command needn't run again on the repeater.
