[RFC PATCH v5] media: mediatek: vcodec: support stateless AV1 decoder
Xiaoyong Lu
xiaoyong.lu at mediatek.com
Fri Sep 30 18:29:15 PDT 2022
Add mediatek av1 decoder linux driver which use the stateless API in
MT8195.
Signed-off-by: Xiaoyong Lu<xiaoyong.lu at mediatek.com>
---
Changes from v4:
- convert vb2_find_timestamp to vb2_find_buffer
- test by av1 fluster, result is 173/239
Changes from v3:
- modify comment for struct vdec_av1_slice_slot
- add define SEG_LVL_ALT_Q
- change use_lr/use_chroma_lr parse from av1 spec
- use ARRAY_SIZE to replace size for loop_filter_level and loop_filter_mode_deltas
- change array size of loop_filter_mode_deltas from 4 to 2
- add define SECONDARY_FILTER_STRENGTH_NUM_BITS
- change some hex values from upper case to lower case
- change *dpb_sz equal to V4L2_AV1_TOTAL_REFS_PER_FRAME + 1
- test by av1 fluster, result is 173/239
Changes from v2:
- Match with av1 uapi v3 modify
- test by av1 fluster, result is 173/239
