Hello,
I have an application that I records video from a Dazzle DVC100 video capture device using mencoder that I'd like to switch over to using avconv. With mencoder I would capture and encode video like this: mencoder -tv driver=v4l2:norm=NTSC:input=0 -nosound -ovc lavc -lavcopts vcodec=mpeg4 -o file.avi -vf pp=li tv:// I'm trying to reproduce this functionality with avconv but not having a lot of luck so far. After multiple attempts I got the following avconv command to work to encode video from a video camera connected to the composite input on the capture card: avconv -y -f video4linux2 -i /dev/video1 -r 30 -an -strict experimental test.avi avconv version v9-2308-gfb13fe8, Copyright (c) 2000-2013 the Libav developers built on Oct 26 2013 11:35:11 with gcc 4.8 (Debian 4.8.1-10) [video4linux2 @ 0x2857820] Estimating duration from bitrate, this may be inaccurate Input #0, video4linux2, from '/dev/video1': Duration: N/A, start: 11381.028327, bitrate: 165888 kb/s Stream #0.0: Video: rawvideo, yuyv422, 720x576, 165888 kb/s, 25 fps, 1000k tbn Output #0, avi, to 'test.avi': Metadata: ISFT : Lavf55.7.0 Stream #0.0: Video: mpeg4, yuv420p, 720x576, q=2-31, 200 kb/s, 30 tbn, 30 tbc Stream mapping: Stream #0:0 -> #0:0 (rawvideo -> mpeg4) Press ctrl-c to stop encoding However the resulting video isn't right: http://www.libertas-tech.com/test.avi Am I missing something on the avconv command? I'm not sure how to select the source input from the capture card (composite vs svideo) or specify NTSC vs PAL. Keith.
