6 The recommended version of FFmpeg for use with this release is 0.6.1.
7 There were quite a few enhancements and changes including a minor interface
8 change. Therefore, this release gets a jump in the versioning.
12 - Added (Y'CbCr) colorspace attribute.
13 - Added mlt_profile_clone().
14 * Added mlt_consumer_position() and Mlt::Consumer::position().
15 * Added Mlt::Properties::wait_for(string).
16 * Added a version API: mlt_version_get_int() and others.
17 * Added Mlt::Producer::pause().
18 * Added mlt_frame_write_ppm() for debugging.
21 * Added automatic detection of profile from first input when profile
23 * Now exits with error result when consumer fails fatally.
26 * Added swfdec producer for Flash files including variables support.
27 (Does not support audio.)
28 * Added consumer for Blackmagic Design DeckLink SDI and Intensity HDMI.
29 * Added Y'CbCr colorspace conversion and option to use full luma range.
30 * Added (de)serialization of profile to XML.
31 * Added support for #frame# variable to the data_show filter.
32 * Added support for frei0r string parameters.
33 * Make FFmpeg formats and codecs available as properties (not just stderr).
34 * Try to load .xml file as MLT XML.
35 * Added a consumer-sdl-paused event to sdl_preview.
36 * Added a consumer-fatal-error event to avformat.
37 * Change composite transition to default to progressive rendering; field-
38 based rendering available only explicitly.
43 This is a quick followup to the 0.5.8 release to address an issue I want to
44 address immediately. I noticed an extra unconditional colorspace conversion
45 to and from RGB was added for all YCbCr (YUV) video sources. In addition, I
46 have enabled the avcolor_space filter on OS X since it works now.
51 The recommended version of FFmpeg for use with this release is 0.6.
52 This is a maintenance release to address some bugs that appeared
53 thus far in the 0.5.x series. Beyond that is a few enhancements:
55 * Added EXIF-based auto-rotation of images to pixbuf and qimage producers.
56 * Improved quality of libswscale-based image conversion and scaling.
57 * Added channelswap and panner audio filters; panner also does balance.
58 * Improve audio waveform and add audiowave video filter.
59 * Enhanced luma filter to work with animated filters such as affine.
60 * Automatically crop 8 bottom lines of 1088 source in a 16:9 project
61 (common in Canon EOS digital cameras).
62 * Added support for inline images in kdenlivetitler.
67 The recommended version of FFmpeg for use with this release is 0.6.
68 This is a maintenance release to address some bugs that appeared
69 this far in the 0.5.x series. Beyond that it a few enhancements:
71 * Added interpolation to the affine transition and filter.
72 * Added multi-track audio encoding to avformat consumer.
73 * Added interlaced field rendering to kdenlivetitle producer.
78 The recommended version of FFmpeg for use with this release is SVN r21322.
79 This is another maintenance release to address some bugs that appeared
80 this far in the 0.5.x series. Beyond that it adds two things that only
81 very specific users will see:
83 * Added C# (ECMA CLR) binding (not enabled by default).
84 * Linsys SDI consumer now configures itself from MLT profile.
89 The recommended version of FFmpeg for use with this release is SVN r21322.
90 This is a minor maintenance release, but it is interesting because it now
91 enables usage of libswscale as the default choice for image scaling,
92 image format conversion, and color space conversion. That gives better
93 quality and performance. In addition, there are some improvements in the
94 sdl_preview consumer to make it suitable for use in OpenShot 1.1. Other
97 * Fixed mlt++/MltFilteredProducer
98 * Fixed playing to the end in Kdenlive (mantis bug 1207)

130 setting environment variable MLT_NO_VDPAU=1 or property novdpau=1.
131 - added caching of FFmpeg contexts and decoded images
132 This allows large numbers of clips in a project avoiding limitations
133 with number of threads and file descriptors permitted per process.
