- It appears that the root cause of the corruption is the loss of some reference info of the RASL pictures at VA-API driver level.
- For reasons that are not documented in VA-API, or simply implementation limitations, the DPB buffer status when a CRA picture is decoded, needs to be sent to VA-API driver to the correct decoding of the associated RASL pictures. The info is stored in PocStFoll and PocLtFoll and is not needed for CRA picture decode, which is an intra picture. Without this info, the following RASL picture decode will run into problem even when its reference picture info is correctly specified.
- Note this appears to be a VA-API specific issue because it did not occur on other platforms.
- When we hit IRAP (Intra Random Access Point) picture and need to bump all remaining decoded pictures from DPB, call display callback immediately, instead of delaying the callback to the IRAP decode process.
* * 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.
* * 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 a few error checks and minor format changes.
* * 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.
* commending out ParseSeiMessage because it is causing segfault
* CMake changes for valgrind
* added function pointer validity for sei callback
* fix review comments
Root cause: num_entry_point_offsets in the slice header of frame #2164 is 674, exceeding the entry_point_offset_minus1[440] array size. Parser writes beyond the array boundary, corrupting memory. Frame #2164 is not in conformance of the HEVC spec.
We need to put the constraint from the spec on the num_entry_point_offsets parsed from the stream. Also need to change the array size to the max possible for 8K.
* * rocDecode/HEVC: Fixed a bug in IRAP picture order count calculation. Added a few picture type check utilities.
* * rocDecode/HEVC: Minor coding style changes. No functional changes.
* added picture_index associated with frame and fixed bug
* added option to force low_latency display
* add force_zero_latency option for videodecode sample
* * rocDeocde/HEVC: Added several "reserved" fields to structs to match the corresponding VA-API structs.
* * rocDecode/HEVC: Added decode submission to VA-API driver.
* * rocDecode/HEVC: Corrected data buffer id type.
* * rocDecode/HEVC: Filled HEVC picture parameter structures for decode callback. Added some missing inferences in tile size and weighted prediction table parsing.
* * rocDecode/HEVC: Changed CurrPicIdx assignment from POC to pic_idx.
* * rocDecode/HEVC: Rmoved one TODO comment, which has been done.
* * rocDecode/HEVC: Corrected two typos in comment.
* * rocDecode/HEVC: No need to set up scaling lists in decode callback when scaling list is not enabled.
