Hello everybody,
I want to record audio and video from a analogue to digital converter
Pinnacle Dazzle DVC100.
Command :
./ffmpeg -debug 1 -f pulse -i alsa_input.pci-0000_00_14.2.analog-stereo
-f v4l2 -i /dev/video0 /Store3/Test/copy_`date +%m%d_%H%M`.avi

Recording audio only works well with:
./ffmpeg -debug 1 -vn -f pulse -ar 44100 -ac 2 -channel_layout stereo -i
alsa_input.pci-0000_00_14.2.analog-stereo -ac 2 -channel_layout stereo
-c:a copy /Store3/Test/copy_`date +%m%d_%H%M`.wav
Moreover with alsa, this command was working few months ago and not
working now :
./ffmpeg -f alsa -i hw:0,0 -f v4l2 -channel 1 -i /dev/video0 -map 0:0
-map 1:0 -c:v ffvhuff /Store3/Test/test_`date +%Y%m%d_%H%M`.avi
Is there a mistake in the audio/video command line or is there something
else ?
Many thanks
