Missing duration

[ralf.butler]

Dear All,

I capture (only 5 sec for testing purposes) from /dev/video0:

Code: Select all

cvlc --color --run-time=5 v4l2:///dev/video0:norm=secam:frequency=543250:size=320x240:channel=0 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,venc=ffmpeg{keyint=80,hurry-up,vt=800000},deinterlace}:std{access=file,mux=ts,dst=/tmp/mytest.avi}'

Strange thing is, the output video is generated correctly, but the duration time is indicated as 0. I can play the output video with vlc but it shows it's duration of 0sec. What is wrong?

Thank you very much,
Ralf

You're muxing to MPEG TS, which doesn't show time information in VLC as it is an encapsulation format which is meant to be of infinite duration. Putting a *.avi to the file name doesn't solve this. Better mux to a container format, which supports time information correctly, such as MP4 or ASF (if you need WMP compatibility).

Hey, great! Thank you very much! This works.
