Subject: [PATCH v6 0/4] media: meson: vdec: Add compliant H264 support
Hello,
This patch series aims to bring H.264 support as well as compliance update
to the amlogic stateful video decoder driver.
The issue in the V1 patchset at [1] is solved by patch #1 following comments
and requirements from hans. It moves the full draining & stopped state tracking
and handling from vicodec to core v4l2-mem2mem.
The vicodec changes still passes the v4l2-utils "media-test" tests, log at [5]:

With this, it also passes vdec v4l2-compliance with H264 streaming on Amlogic G12A
and Amlogic SM1 SoCs successfully.
