Subject: [PATCH v2] media: mediatek: vcodec: Handle VP9 superframe bitstream with 8 sub-frames
Date: Thu, 29 Feb 2024 11:02:49 +0800 [thread overview]
Message-ID: <20240229030249.3404-1-irui.wang@mediatek.com> (raw)
The VP9 bitstream has 8 sub-frames into one superframe, the superframe
index validate failed when reach 8, modify the index checking so that the
last sub-frame can be decoded normally with stateful vp9 decoder.
Signed-off-by: Irui Wang <irui.wang@mediatek.com>
---
changed with v1:
- add a new define 'VP9_MAX_SUPER_FRAMES_NUM' for superframes.
