[ROCm/rocdecode commit: 8ec38d2d24]
* * rocDecode/HEVC: Fixed a couple of issues with reconfiguration of decoder when video size is changed.
- Picture width and height variables were interchangeably used to represent coded picture size and display size, resulting reconfiguration errors. Now we use different variables to represent coded and display sizes.
- Fixed a file overwriting issue in video size change case, where the display size can remain the same when coded size changes with specific cropping offsets.
* * rocDecode/HEVC: Added some fixes to decoder reconfiguration.
- Added support for MD5 calculation in reconfigure flush callback. This fixed MD5 check failure on conformance streams with size changes.
- Fixed total decoded frame number report with reconfigure when file dump or MD5 is not enabled. We need to call flush with reconfigure unconditionally (but with different actions).
- Added the missing reconfigure flush when coded size is not changed but display size is changed.
* * rocDecode/HEVC: Corrected an error in GetDecodedWidth() method. Should use coded_width_, instead of disp_width_.
[ROCm/rocdecode commit: ccd813a2da]
* * rocDecode/HEVC: Fixed the random crash associated with undecodable RASL pictures.
- When a CRA picutre occurs, all the pictures in the DPB are emptied. However, the following RASL (Random Access Skipped Leading) picture can still reference these emptied pictures, making them undecodeble.
- We initialized the reference picture lists with (0xFF), representing invalid picture index. Normally these invalid indices are replaced by valid values during RPS decoding. However, on undecodable RASL pictures, we can not find an existing reference picture in DPB, leaving the invalid index untouched and resulting invalid indexing later on.
- Now we initialize the reference picture lists with a valid value 0. Also we add index range check on reference buffer at VA-API layer to avoid invalid memory access.
* * rocDecode/HEVC: Fixed a typo in sampel app message.
[ROCm/rocdecode commit: 0fbd030b5d]
* * rocDecode/HEVC: Added script to run static conformance test.
- The script runs videodecode app in MD5 check mode on the conformance streams.
- The MD5 check results are stored in rocDecode_conformance.log and printed out.
* * rocDecode: Fixed formatting in README.md.
* * rocDecode/Conformance test: Added the missing exit when number of streams does not match number of reference MD5 digests.
* * rocDecode/Conformance test: Do case insensitive sorting.
* * rocDecode/Conformance test: Fixed a typo in the script.
* * rocDecode/Conformance test: Added info on the number of streams that fail to complete decode.
* * rocDecode/Conformance test: Added the missing message of the aborted streams to stdout.
[ROCm/rocdecode commit: 3598f4d96e]
* * rocDecode: Added a command option "-md5_check" to compare the MD5 of the decoded YUV to the reference MD5. This ficilitates decoder conformance test automation.
* * rocDecode/HEVC: Changed file and string operation from C code to C++ code.
* * rocDecode/HEVC: Updated README.md for videoDecode sample.
[ROCm/rocdecode commit: 583e72720a]
* * rocDecode/HEVC: Added support for MD5 message digest generation.
- Command option "-md5" triggers MD5 calculation and output.
* * rocDecode/HEVC: Changed C type casting to C++ type casting.
[ROCm/rocdecode commit: ad20961c4a]
* adding surface mem type as user arg
* adding mem type user arg for all apps
* readme update
* readme updates on all apps
[ROCm/rocdecode commit: 449572f9bf]
* * rocDecode/HEVC: Added picture output operation in DPB and display callback function.
- To avoid serialization of decode submissions and/or display callback in certain cases, increased DPB buffer size by 1 and tweaked picture bumping procedure.
* * rocDecode/HEVC: Added flushing of the remaining pictures from DPB at the end of decode session.
* * rocDecode/HEVC: Changed output_pic_num to num_output_pics to void some confusion. Set top_field_first to 1.
* * rocDecode/HEVC: Added a few return error checks.
[ROCm/rocdecode commit: 624c3c0f09]
* * rocDecode/HEVC: Re-enabled SEI message processing.
- Added "-sei" command option to extract SEI messages from stream.
- Added support for SEI info parsing for multiple SEI NAL units with multiple payloads.
- Fixed a SEI syntax parsing issue and several procssing issues.
- Fixed a double free memory issue in SEI data buffer handling in HandlePictureDisplay().
* * rocDecode/HEVC: Coding format changes.
* * rocDecode/HEVC: Minor format changes.
[ROCm/rocdecode commit: ad186a90da]
* code cleanup - use google style for videodecode sample and RocVideoDecoder class - no functional change
* rename SaveSurfToFile to SaveFrameToFile
