Hello, This patchset aims to bring VP9 decoding support to Amlogic GXL, G12A & SM1 platforms for the amlogic stateful video decoder driver. With this, it passes v4l2-compliance with streaming on Amlogic G12A and Amlogic SM1 SoCs successfully using the stream at [1] with a fixed pyv4l2compliance script for VP9 at [2]. The original script kept the IVF headers in the stream, confusing the decoder. The fixed script only extracts the payload from the IVF container. The decoder has been tested using the Google CTS TestVectorsIttiam VP9 yuv420 samples and the VP9 Decoder Performance streams at [5], decoding all streams from Profile 0 and 2 up to Level 4.1, with 10bit downsampling to 8bit. This patchset depends on : - H.264 and compliance at [4] Changes since v2 at [6]: - Rebased on H.264 and compliance at [4] Changes since v1 at [3]: - Fixed compliance for delta frame resize, but proper ref keeping is broken - Added warns for delta frame resize, to be fixed in a following patchset - Added VP9 probabilities parsing and transformation support to decore the VP9 performance streams - Fixed refs keeping, avoid deleting necessary refs for next frame - Properly used the kernel clamp_val() macros - Zeroed the workspace to avoid refs handling glitches - Add lock around the flush & stop to avoid race between IRQ and drain/stop [1] https://github.com/superna9999/pyv4l2compliance/raw/tests/output/Jellyfish_1080_10s_5MB.vp9.hdr [2] https://github.com/superna9999/pyv4l2compliance [3] https://lore.kernel.org/linux-media/ [4] https://lore.kernel.org/linux-media/20200116133025.1903-1-narmstrong@xxxxxxxxxxxx [5] https://www.webmproject.org/vp9/levels/ [6] https://lore.kernel.org/linux-media/20191217111939.10387-1-narmstrong@xxxxxxxxxxxx The compliance log is: #
