Displaying transcoded stream trouble

Postby Grim » 11 Jun 2010 18:00

Hello all,

I am trying to display transcoded input from a Dazzle (DVC100) in hopes that I can see the quality that is being streamed as well as, more importantly, overlay a logo on top in the future.

I am using Windows XP and this is the command I've been trying to use:

Code: Select all

vlc.exe -vvv -I dummy dshow:// --dshow-caching=200 --dshow-vdev="Dazzle DVC100 Video Device" --dshow-adev="Dazzle DVC100 Audio Device" --dshow-size=720x480 --dshow-chroma=YUY2 --dshow-fps=0 --dshow-audio-channels=2 --dshow-audio-samplerate=96000 --dshow-audio-bitspersample=16 --aspect-ratio=16:9 --width=480 --height=270 --ignore-config --sout="#transcode{vcodec=h264,vb=800,scale=1,width=480,height=270,acodec=mp4a,ab=128,channels=2,samplerate=96000}:display"
A display window pops up but unfortunately the first frame freezes but I can hear audio. I have tried 1.0.5 and 1.1.0 RC. The repeated outcome looks like this:

Code: Select all

I’m not sure if this is beyond the capabilities of VLC or if I’m doing something wrong. Any help would be greatly appreciated.
