|Summary||0004845: Restrict set of features in FFmpeg cinematics|
|Description||FFmpeg is a huge library with tons of codecs and formats, and the actual set of supported formats greatly depends on how it was configured. It is hard to keep this set constant over time, which can potentially result in breaking TDM cutscenes regularly in some distant future. To avoid breaking maps, there is a plan to restrict the set of supported formats/codecs to the bare minimum. This way the chance of breaking existing video files should become much lower.|
Unfortunately, the unrestricted FFmpeg is already released with TDM 2.06, so the restricted version will be used starting from 2.07.
The restricted set is:

Done in svn rev 7511.
This commit includes rolling back to FFmpeg 3.3.7 (getting WinXP back) and rebuilding all FFmpeg libs for all four supported platforms.
I have also written a detailed FFmpeg compilation guide on wiki:
It exactly describes how the new libs were created.
Also committed a set of test videos in svn rev 15239.
All these files are internal: they are used by TDM maintainers to check that FFmpeg works properly.
They are referenced on the wiki page:
Updated the wiki page about FFmpeg videos:
Now it says explicitly which containers and codecs are supported.
Ok, made sort of announcement in the mapper's forum:
It turned out that new FFmpeg version produces severe stutters due to multithreading efficiently disabled. The issue was caused by FFmpeg update.
Restored back multithreading in FFmpeg in svn rev 7606.
Now the number of threads is set to "auto", as it was in TDM 2.06.
The set of supported formats and codecs has been further restricted for 2.10.
Now only mp4 + h264 + aac and roq are supported, i.e. they is only one combination for the "new cinematics".
The commits are:
r9326. Further restrict FFmpeg support to mp4 + h264 + aac and roq.
r9327. Rebuild FFmpeg artefacts after recent formats restriction.
