6 The recommended version of FFmpeg for use with this release is SVN r21322.
7 This is a minor maintenance release, but it is interesting because it now
8 enables usage of libswscale as the default choice for image scaling,
9 image format conversion, and color space conversion. That gives better
10 quality and performance. In addition, there are some improvements in the
11 sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other
14 * Fixed mlt++/MltFilteredProducer
15 * Fixed playing to the end in Kdenlive (mantis bug 1207)
