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

57 change. Therefore, this release gets a jump in the versioning.
61 - Added (Y'CbCr) colorspace attribute.

90 Version 0.5.10 - September 13, 2010
92 This is a quick followup to the 0.5.8 release to address an issue I want to
93 address immediately. I noticed an extra unconditional colorspace conversion
94 to and from RGB was added for all YCbCr (YUV) video sources. In addition, I
95 have enabled the avcolor_space filter on OS X since it works now.
98 Version 0.5.8 - September 12, 2010
100 The recommended version of FFmpeg for use with this release is 0.6.
101 This is a maintenance release to address some bugs that appeared
102 thus far in the 0.5.x series. Beyond that is a few enhancements:
104 * Added EXIF-based auto-rotation of images to pixbuf and qimage producers.
105 * Improved quality of libswscale-based image conversion and scaling.

114 Version 0.5.6 - June 20, 2010
116 The recommended version of FFmpeg for use with this release is 0.6.
117 This is a maintenance release to address some bugs that appeared
118 this far in the 0.5.x series. Beyond that it a few enhancements:
120 * Added interpolation to the affine transition and filter.
121 * Added multi-track audio encoding to avformat consumer.

127 The recommended version of FFmpeg for use with this release is SVN r21322.
128 This is another maintenance release to address some bugs that appeared
129 this far in the 0.5.x series. Beyond that it adds two things that only
130 very specific users will see:
132 * Added C# (ECMA CLR) binding (not enabled by default).
133 * Linsys SDI consumer now configures itself from MLT profile.
136 Version 0.5.2 - March 10, 2010
138 The recommended version of FFmpeg for use with this release is SVN r21322.
139 This is a minor maintenance release, but it is interesting because it now
140 enables usage of libswscale as the default choice for image scaling,
141 image format conversion, and color space conversion. That gives better
142 quality and performance. In addition, there are some improvements in the
143 sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other
146 * Fixed mlt++/MltFilteredProducer
147 * Fixed playing to the end in Kdenlive (mantis bug 1207)

180 - added caching of FFmpeg contexts and decoded images
181 This allows large numbers of clips in a project avoiding limitations
182 with number of threads and file descriptors permitted per process.
183 You can disable image caching with property noimagecache=1.
184 - added variant of producer named avformat-novalidate
185 - restored support for video4linux(2)
