Capture Easycap audio and video to MJPEG and raw sound on linux

[Sérgio Agostinho]

Hey,

Are you sure your camera supports that format and resolution? Can you run
guvcview or something similar to list your dongle's accepted formats and
resolution?. Because I tested a pipeline similar to yours and I got no
errors.

gst-launch-1.0 -v avimux name=mux videotestsrc ! video/x-raw, format=YV12,
width=720, height=576 ! videorate ! video/x-raw, format=YV12,
framerate=25/1 ! videoconvert ! video/x-raw, format=YV12, width=720,
height=576 ! jpegenc ! queue ! mux. audiotestsrc ! audio/x-raw,
format=S16LE, rate=48000, channels=2 ! audiorate ! audioresample !
audio/x-raw,rate=44100 ! audioconvert ! audio/x-raw, channels=1 ! queue !
mux. mux. ! fakesink

Cheers
