Strange behaviour I noticed is that when I tried capturing video and audio, I can not capture the audio afterwards any more,
If I run the command for only video capturing then vlc or ffplay can play the video successfully :įfmpeg -f video4linux2 -i /dev/video0 -vcodec mpeg4 -b 12000k -r 25 test5.avi Estimating duration from bitrate, this may be inaccurate **video:0kB audio:213kB** global headers:0kB muxing overhead 6.902375% If I reduce the command for only capturing audio, then the audio file can be played successfully :įfmpeg -f alsa -ac 2 -i hw:3,0 -acodec ac3 -ab 128k test5.avi Estimating duration from bitrate, this may be inaccurateĭuration: N/A, start: 70395.998935, bitrate: N/A The encoder will guess the layout, but it might be incorrect. Stream #0.0: Audio: pcm_s16le, 44100 Hz, 2 channels, s16, 1411 kb/sĮstimating duration from bitrate, this may be inaccurate The log is : Estimating duration from bitrate, this may be inaccurateĭuration: N/A, start: 69930.998994, bitrate: N/A įfmpeg -f alsa -ac 2 -i hw:3 -f video4linux2 -i /dev/video0 -acodec ac3 -ab 128k -vcodec mpeg4 -b 6000k -r 25 test5.avi At the end it indicates the size of the video and audio captured. ĭuring the capturing I don't get any errors. If I play the captured video with vlc or with ffplay I got only 3 seconds sound and then a silence for the rest of the video. I don't succeed to get the audio when it is played. I'm capturing a video by means of an USB Terratec Grabster AV350 (which is based on the em2860 chip).
