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"
