* * rocDecode/ES parser: Added elementary stream file parser for HEVC and AVC.
* * rocDecode/ES parser: Added elementary stream file parser for AV1. Also cleaned up the bitstream ring buffer code.
* * rocDecode/ES parser: Added the IVF container file parser for AV1. Also fixed a bug in fill ring buffer function.
* * rocDecode/ES file parder: Added supported stream type detection.
- The stream type detection checks the unique syntax patterns of the stream type and calculate the likeliheed score. Based on the score, the most likely type is determined.
- The current supported stream types are: AVC/HEVC/AV1 elementary streams, IVF AV1 streams.
* * rocDecode/ES file parser: Fixed an AVC decode regression due to a copy and paste error.
* * rocDecode/ES file parser: Added bit depth parsing for codec support check; Added stronger AV1 detection for IVF AV1 stream type.
* * rocDecode/ES file parser: Removed debugging logs.
* * rocDecode/ES file parser: Added exmaple code to use the built-in file parser.
* * rocDecode/Bitstream reader: Renamed the elementary parser feature to bitstream reader and re-organized the code.
- Moved the bitstream reader code to rocDecode core lib from utility.
- Added bitstream reader interface in parallel with rocDecode parser and decoder interfaces.
* * rocDecode/Bitstream reader: Added sample to use bitstream reader, instead of FFMPEG demuxer, to get picture data. Also reverted the original sample app back to using FFMPEG demuxer only.
* * rocDecode/Bitstream reader: Renamed the new sample app.
* * rocDecode/Bitstream reader: FFMPEG dependency reduction.
- Moved MD5 functions out of RocVideoDecoder utility class. This removed RocVideoDecoder's dependency on FFMPEG.
- Added the new MD5 utility, which depends on FFMPEG lib. MD5 message digest generation is now performed in the MD5 utility.
- Modified decode sampples that uses MD5 generation function.
- Removed FFMPEG dependency from video decoder basic sample.
* * rocDecode/Bitstream reader: Added option to use bitstream reader to video decode sample and conformance test script. Added the missing destroy bitstream reader call in video decode basic sample.
* * rocDecode/Bitstream reader: Minor format change. No functional changes.
* * rocDecode/Bitstream reader: Added handling of unsupported stream file type by the bitstream reader to decode sample apps.
* * rocDecode/Bitstream reader: Fixed build errors of several samples.
* * rocDecode/Bitstream reader: Added changes based on review comments.
* * rocDecode/Bitstream reader: File name changes based on review comments.
* * rocDecode/Bitstream reader: Moved MD5 code into single header file. Added changes based on review comments.
* * rocDecode/Bitstream reader: Removed redundant path.
* * rocDecode/Bitstream reader: Changed rocDecode version to 0.10.0. Added minor changes based on review comments.
