42 Since FFmpeg forked and there were a few releases, there is no recommended
43 version at this time. With that said, there were changes to accomodate the
44 API changes with some moderate testing of the 0.6, 0.7, and 0.8 series
45 releases of both FFmpeg and Libav.
48 Version 0.7.2 - May 1, 2011
50 This is a minor release to fix a few things between the 0.7.0 release
51 and the release of Kdenlive 0.8. I recommend Kdenlive v0.8 users to
52 upgrade to this version of Mlt. Beyond that there are some exciting
53 additions to the Blackmagic Design DeckLink plugin!
56 * Added mlt_profile_list().

122 The recommended version of FFmpeg for use with this release is 0.6.1.

124 change. Therefore, this release gets a jump in the versioning.

157 Version 0.5.10 - September 13, 2010
159 This is a quick followup to the 0.5.8 release to address an issue I want to
160 address immediately. I noticed an extra unconditional colorspace conversion
161 to and from RGB was added for all YCbCr (YUV) video sources. In addition, I
162 have enabled the avcolor_space filter on OS X since it works now.
165 Version 0.5.8 - September 12, 2010
167 The recommended version of FFmpeg for use with this release is 0.6.
168 This is a maintenance release to address some bugs that appeared
169 thus far in the 0.5.x series. Beyond that is a few enhancements:
171 * Added EXIF-based auto-rotation of images to pixbuf and qimage producers.

183 The recommended version of FFmpeg for use with this release is 0.6.

194 The recommended version of FFmpeg for use with this release is SVN r21322.
195 This is another maintenance release to address some bugs that appeared
196 this far in the 0.5.x series. Beyond that it adds two things that only
197 very specific users will see:
199 * Added C# (ECMA CLR) binding (not enabled by default).
200 * Linsys SDI consumer now configures itself from MLT profile.
203 Version 0.5.2 - March 10, 2010
205 The recommended version of FFmpeg for use with this release is SVN r21322.
206 This is a minor maintenance release, but it is interesting because it now
207 enables usage of libswscale as the default choice for image scaling,
208 image format conversion, and color space conversion. That gives better
209 quality and performance. In addition, there are some improvements in the
210 sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other
213 * Fixed mlt++/MltFilteredProducer

249 with number of threads and file descriptors permitted per process.
250 You can disable image caching with property noimagecache=1.
251 - added variant of producer named avformat-novalidate
