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]: [...] vicodec media controller compliance tests Thu Jan 16 13:00:56 UTC 2020 v4l2-compliance SHA: 7ead0e1856b89f2e19369af452bb03fd0cd16793, 64 bits [...] Summary: Total for vicodec device /dev/media3: 7, Succeeded: 7, Failed: 0, Warnings: 0 Total for vicodec device /dev/video13: 51, Succeeded: 51, Failed: 0, Warnings: 0 Total for vicodec device /dev/video14: 51, Succeeded: 51, Failed: 0, Warnings: 0 Total for vicodec device /dev/video14: 51, Succeeded: 51, Failed: 0, Warnings: 0 Total for vicodec device /dev/video14: 51, Succeeded: 51, Failed: 0, Warnings: 0 Total for vicodec device /dev/video14: 51, Succeeded: 51, Failed: 0, Warnings: 0 Total for vicodec device /dev/video14: 51, Succeeded: 51, Failed: 0, Warnings: 0 Total for vicodec device /dev/video14: 51, Succeeded: 51, Failed: 0, Warnings: 0 Final Summary: 364, Succeeded: 364, Failed: 0, Warnings: 0 Thu Jan 16 13:02:59 UTC 2020 With this, it also passes vdec v4l2-compliance with H264 streaming on Amlogic G12A and Amlogic SM1 SoCs successfully.
