[MPlayer-dev-eng] [PATCH] Realtime EDL

[Michael Halcrow]

Hi. I made a patch.

This is my first contribution to mplayer. I read through the
patches.txt; hope I followed all the rules. I tested the patch on a CVS
checkout, and it seemed to work fine (after adding "#define USE_EDL" in
config.h).

This is good for those who don't want their kids to see
sex/violence/etc. on a DVD (or for those who don't particularly care for
it themselves). Hey, it could even be used to edit out Jar-Jar. It
requires an edit decision list (EDL) with the format:

[start second] [end second] [action]

For now, I've only implemented skipping sections based on the number of
seconds passed (action ID 0). It's pretty braindead; those more familiar
with the functionality of mplayer may be able to find a better way to
implement it, but at least this is a start. I spent more time figuring
out how to add a new command-line option than actually implementing the
functionality. In the future, maybe this EDL file could be in XML
format, it could apply to mencoder (as a backend to a non-linear video
editing program), yadayada.

Example EDL:

3 15 0
20 30 0

This will skip from second 3 to second 15, and then from second 20 to
second 30 during playback. The EDL is enabled and the file specified
with an added "-e" flag, like "-e matrix.edl".

In the near future, I will probably implement a "EDL creation mode",
where whenever something naughty happens, the user can hit a key, and an
EDL will be generated from those keypresses.

There still needs to be added to the ./configure script a way to specify
that you want EDL (#define USE_EDL in config.h), so that the #ifdef's
relating to it work. Otherwise, EDL is never enabled ;-). Feedback
(suggestions, ideas, insults :-) is welcome.
