- Build with ffmpeg unconditional
* Thu Apr 21 2016 firstname.lastname@example.org
- Update to version 6.2.0:
+ There are no framework changes in this release. The major
announcement is the introduction of support for libavfilter!
This is still a work-in-progress. It is limited to FFmpeg 2.3
and up, and there are a number of filters that are black-listed
because they are known to not integrate with MLT, which is not
a full libav* environment or simple wrapper for it. There are
likey avfilters that are not yet black-listed but might not
work because they have not been completely tested. Also, they
do not support MLT's keyframable property animation nor its
frame-threaded parallelism due to architectural or integration
limitations. However, some avfilters are slice-threaded
(internal parallelism), and that works. Finally, libavfilter
filtergraph syntax is not supported either.
All of the supported libavfilters are exposed as MLT filters
beginning with the prefix "avfilter." All of the avfilter
parameters are exposed as MLT properties with the "av." prefix
to prevent clashes with MLT properties. You can run `melt
- query filters` to see the new avfilters, and `melt -query
filter=avfilter.rotate`, for example, to view generated
documentation for an individual filter.

- Added support for libavfilter to avformat module.
