The current behavior is to check out the last commit from ffmpeg branch 2.8
when the directory <cinelerra_root>/ffmpeg does not exist. When the
directory does exist, configure does not make any attempt to download
I expect that fixes in released versions are only bugfixes and api does not
change. User can upgrade ffmpeg when he/she thinks that improves
something. I think that this situatioin will be quite rare.
Expert user can download any version of ffmpeg and put it into
<cinelerra_root>/ffmpeg. This does not conflict with configure.
<cinelerra_root>/.configure sould be run after changing ffmpeg because it
attempts to configure the internal ffmpeg. Users should be aware that
cinelerra with such a custom ffmpeg may not compile - api changes are
When you configure with external ffmpeg nothing is downloaded.

My goal is to keep cinelerra compatible with multiple versions on ffmpeg.
So the prefferred commit is overkill.
