--- Comment #15 from Nicolas Dufresne (stormer) <nicolas.dufresne at collabora.co.uk> ---
So I think there is two bugs, the patch in comment 14 fixes the regression.
Basically an out of segment buffer is a buffer that has a PTS and PTS +
duration that falls out of segment.

The second bug, which was present before the integration of proper DTS support
for H.264 is that basesink will clip and break certain stream (if segment is in
TIME format). This problem already existed, and should be handled differently.
A simple option would be to add a clip-to-segment property to basesink, this
way application (or sub-class) can choose. But let's file a seperate bug for
that.
