* * 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. --------- Co-authored-by: Kiriti Gowda <kiritigowda@gmail.com>
