[gst-devel] video playback fast (record with v4l2src)

[Edgard Lima]

I have the same bug to record from v4l2src and alsasrc to ogg.

It works fine with videotestsrc and alsasrc

I have compared the output from videotestsrc is-live=true ! fakesink 
with output from v4l2src ! fakesink. The only difference I could notice 
was the first timestamp from videotestsrc starts from 0 and from v4l2src 
starts from 60ms.

Then I hacked v4l2src (shift timestamps) to start from 0. But it still 
doesn't work.

Any ideas are welcome.
(the same happens for v4lsrc as has been discussed in previous mails)
