editing services: remove video segments without transcoding

[Felix Schwarz]

Thanks for the pointers.

Looks like you're right about the incompleteness of encodebin but anyway for
my test video reencoding only took about two minutes which is fine (45 minute
video).

The only is that the bitrate (variable bitrate) of the output video is much
lower than the source bitrate (~400 Kb/s vs. ~850 Kb/s). I guess I have to
check how I can influence the max bitrate for encoding.

Btw: If I want to improve the "non-reencoding algorithms" do I have to look
only at encodebin or also other places (using h.264/divx formats mostly)?

Actually I wouldn't mind reencoding some small part of the video. My main goal
is that the visual quality stays the same and the cutting the video doesn't
take ages. Is that (reencoding a few frames if first frame is no key frame)
something that GES should handle transparently or do I have to tell it
specifically to reencode?
