Bug Description
Binary package hint: vlc
Trying to capture video from a webcam, I found that
vlc alsa://
will play sound, and
vlc v4l2://
will play video. Getting both together however does not seem to work. Various tutorials suggest
vlc v4l2:// --input-slave alsa://
however, that gives only video. Similarly,
vlc alsa:// --input-slave v4l2://
only plays audio. Specifying the alsa device, alsa://hw:0,0 does not change the behavior, neither does recording to disk instead of immediately playing.
Googling led me to a forum post, http://

This seems to be a weird problem with pulseaudio.
Using alsa://pulse or using padsp for oss emulation solves it. Once I get the time difference between video and audio worked out, I'll update the wiki,
