Description:
FFmpegSource (usually known as FFMS or FFMS2) is a cross-platform wrapper
library around FFmpeg/libav. It gives you an easy, convenient way to say
"open and decompress this media file for me, I don't care how you do it"
and get frame- and sample-accurate access (usually), without having to bother
with the sometimes less than straightforward and less than perfectly documented
libav API.

Why this package is not eligible to be included in Fedora:
it compiles with ffmpeg. It is needed to package the aegisub.

Bogus errors - mostly spelling errors and having devel files in /usr/lib64.

I am Fedora packager already.
