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).
