Hi, Hans.
Gentle ping on this patch series.
To recap, the previous feedback included
- Adding a comment after "V4L2_BUF_TYPE_META_OUTPUT = 14,"
- Fixing a build warning in the venus/vdec.c code
- Removing V4L2_BUF_TYPE_VIDEO_OVERLAY in V4L2_TYPE_IS_OUTPUT()
I have addressed these points in the latest version of the patch series.
Thanks.
Nas.
