1.0.9 ===== - Orc: Complete conversion to Orc and removal of liboil dependency. - Added a lot of orc code to make things faster. A lot faster. - New motion vector generation, enabled by default. - New CBR rate control, enabled by default. - New scene change detection, enabled by default. - Encoder went through several rounds of tuning, improving quality greatly. - New encoder setting "force-profile". Allows easy access to one of three VC-2 profiles (vc2_low_delay, vc2_simple, vc2_main) for intermediate coding. Default is same as before: long-GOP Dirac. - Improved lossless encoding. Works in concert with force-profile. 1.0.8 ===== - encoder: various performance enhancements - Orc: More Orc conversion. The next release will likely require Orc to build. - Add a fast path for 8x8 non-obmc motion blocks. - encoder: Fix the queue-depth setting so that it actually works. - Fix a bitstream conformance bug. Shows up as a psychadelic color pattern. Broken bitstreams should be uncommon, however, if the decoder detects a broken bitstream, it will be played correctly. - Move GStreamer plugin to gst-plugins-bad - encoder: Strictly enforce bit rate. Encoded pictures are cut off if they are larger than the available buffer. - encoder: Change the backref engine to use an IPPPP... structure, using the last two pictures as references. 1.0.7 ===== - Somebody forgot to write release notes for 1.0.7 1.0.6 ===== - Requires liboil-0.3.16 - New configure flag '--disable-encoder' useful for embedded systems that don't require the encoder. - New constant-quality encoding mode, enabled by setting the encoder setting 'rate-control' to 6, and adjusting 'quality' from 0 to 10. (Interesting range is 3-7). - Various encoder improvements - Speed improvements in decoder - API additions for parsing streams in the decoder - API improvements handling interlaced video - Rewrite of the GStreamer elements, including new base classes for video encoding and decoding - Moved extra GStreamer elements to Cog - Experimental code that uses Orc instead of liboil (--enable-orc) 1.0.5-1.0.2 =========== - ... 1.0.1 ===== - Add API reference documentation for SchroDecoder. - Restructure API reference documentation, although coverage is very low. - Default GOP structure now uses 3 reference frames. This gives a very slight improvement in quality. - Fix encode/decode mismatch for low-delay syntax. - Fix brokenness in CBR intra-only encoding - Additional testing and code cleanups - Eliminate artificial width limitation in encoder and decoder. - Fix encoding/decoding of video offset and excursion. - Fix granulepos calculation in GStreamer encoder element - Set DELTA_UNIT correctly in GStreamer encoder element - Update code path used when pthread is disabled. 1.0.0 ===== - Major release 0.2.1 ===== - Encoder and decoder nearly complete. The bitstream is nearly compatible with Dirac, except in a few cases for predicted frames. Note that the Dirac bitstream isn't frozen, so that's kind of irrelevant. - Requires liboil-0.3.10. |
