81 API changes with some moderate testing of the 0.6, 0.7, and 0.8 series
82 releases of both FFmpeg and Libav.
85 Version 0.7.2 - May 1, 2011
87 This is a minor release to fix a few things between the 0.7.0 release
88 and the release of Kdenlive 0.8. I recommend Kdenlive v0.8 users to
89 upgrade to this version of Mlt. Beyond that there are some exciting
90 additions to the Blackmagic Design DeckLink plugin!

194 Version 0.5.10 - September 13, 2010
196 This is a quick followup to the 0.5.8 release to address an issue I want to
197 address immediately. I noticed an extra unconditional colorspace conversion
198 to and from RGB was added for all YCbCr (YUV) video sources. In addition, I
199 have enabled the avcolor_space filter on OS X since it works now.
202 Version 0.5.8 - September 12, 2010
204 The recommended version of FFmpeg for use with this release is 0.6.
205 This is a maintenance release to address some bugs that appeared

242 The recommended version of FFmpeg for use with this release is SVN r21322.
243 This is a minor maintenance release, but it is interesting because it now
244 enables usage of libswscale as the default choice for image scaling,
245 image format conversion, and color space conversion. That gives better
246 quality and performance. In addition, there are some improvements in the
247 sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other
