1.0.10
======
- Build fixes on various platforms
- Speed increases for low-delay syntax
- Fix unaligned access in orc code, which was uncovered by a recent
Orc bug fix. Bump orc requirement to 0.4.10, which makes sure
everyone works right.
- No encoder changes
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.
