Comment (by saste):
Replying to [ticket:694 burek]:
[...]
> The suggestion is to create an enhancement to rearrange timestamps on
the fly, to avoid the need for the tmp file, to be able to speed up/slow
down a video stream (also if possible even without re-encoding it).
What about using the setpts filter?
About avoiding transcoding, that's pretty hard/impossible, as timing
information is only available after decoding (unless you implement a
specific PTS-tweaking bitfilter just for a specific format).
