appsrc, timestamp and filesink

[Walter Lucetti]

What I did was printing out the timestamp for the buffer at each "push
frame" event... and effectively the timestamps were wrong: at the end of a
10 seconds recording I got about 5 seconds of time stamp.

What I noticed is that my source has not a stable fps, varying from 30 fps
to 25 fps...

I thought to use std::chrono to calculate the time elapsed from one push to
the next and use the "real" timestamp setting do-timestamp to false.

Is there a more clever way to do this?

Apparently, the timestamps are incorrect. What you could do is insert the
identity element before the videorate element and examine the timestamps by
setting silent=false on that element. Next step would be to examine the
timestamps before the encoder and see where things go wrong.
