pinnacle dazzle recorder DVC100 streaming with VLC

[eleandar]

Hello,

i'm using ubuntu intrepid with VLC 0.9.4 and i 'm trying to play the DVC100 streaming with VLC.

I could make mplayer play the DVC100 streaming using v4l2 module with the following command:

Code: Select all

mplayer tv:// -tv fps=25:buffersize=64:driver=v4l2:norm=PAL:audiorate=44100:immediatemode=0:device=/dev/video1:forceaudio:adevice=/dev/dsp1

I tried the following command as i found some help in the wiki http://wiki.videolan.org/Documentation:Modules/v4l2.

Code: Select all

vlc v4l2:// :v4l2-dev=/dev/video1 :v4l2-adev=hw:1,0 :v4l2-standard=2 :v4l2-fps=25 :v4l2-samplerate=44100 :v4l2-audio-method=2

But i get the following error and no video:

Code: Select all

[00000409] v4l2 demux error: cannot get audio input characteristics (Argument invalide)

ALSA show me the following devices:

Code: Select all

Can you give some help please ?

I have no problems to use Dazzle DVC100 with VLC using the same command:

david@david-desktop:~$ vlc v4l2:// :v4l2-dev=/dev/video0 :v4l2-adev=hw:1,0 :v4l2-standard=2 :v4l2-fps=30 :v4l2-samplerate=44100 :v4l2-audio-method=2

Im using video0 and fps=30 to get xbox360 videos.
Maybe you have to install the device like i did. Read this web page: http://ubuntuforums.org/showthread.php?t=1101788

There is like a second of lag, but it works properly.
Good luck

Anyone have a clue as to why I'm not getting a new video device when the Dazzle is plugged in?

I've got v4l2 installed and running Ubuntu 8.04 which I believe _should_ work, as per the info above.

Any suggestions would be appreciated.

Cheers!

You need to start playback after the device is detected.

Hi,
i'm using VLC media player 1.0.2 Goldeneye and this worked 4 me:
cvlc v4l2:///dev/video1 --sout="#transcode{vcodec=mp4v,vb=800,scale=2,acodec=mpga,ab=128,channels=2}:std{access=http,mux=asf,dst=0.0.0.0:8080/stream.mpg}"

If u don't want to transcode:
cvlc v4l2:///dev/video1 --sout="#std{access=http,mux=asf,dst=0.0.0.0:8080/stream.mpg}"

I used the command line cvlc but works with vlc too (same)

I just have problems with stream video quality (very bad). If i open the device from other program, like xawtv , quality is good.

Cheers
