This patch series add Mediatek compressed block format V4L2_PIX_FMT_MT21C, the decoder driver will decoded bitstream to V4L2_PIX_FMT_MT21C format. User space applications could use MT8173 MDP driver to convert V4L2_PIX_FMT_MT21C to V4L2_PIX_FMT_NV12M, V4L2_PIX_FMT_YUV420M and V4L2_PIX_FMT_YVU420. MDP driver[1] is stand alone driver. Usage: MT21C -> MT8173 MDP -> NV12M/YUV420M/YVU420 NV12M/NV21M/YUV420M/YVU420M -> mt8173 Encoder -> H264/VP8 H264/VP8/VP9 -> mtk8173 Decoder -> MT21C When encode with MT21 source, the pipeline will be: MT21C -> MDP driver-> NV12M/NV21M/YUV420M/YVU420M -> Encoder -> H264/VP8 When playback, the pipeline will be: H264/VP8/VP9 -> Decoder driver -> MT21C -> MDP Driver -> DRM [1]https://patchwork.kernel.org/patch/9305329/ --- v2: add more information for MT21C in docs-rst --- Tiffany Lin (4): v4l: add Mediatek compressed video block format docs-rst: Add compressed video formats used on MT8173 codec driver vcodec: mediatek: Add V4L2_PIX_FMT_MT21C support for v4l2 decoder arm64: dts: mediatek: Add Video Decoder for MT8173 Documentation/media/uapi/v4l/pixfmt-reserved.rst | 10 +++++ arch/arm64/boot/dts/mediatek/mt8173.dtsi | 44 ++++++++++++++++++++ drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c | 7 +++- drivers/media/v4l2-core/v4l2-ioctl.c | 1 + include/uapi/linux/videodev2.h | 1 + 5 files changed, 62 insertions(+), 1 deletion(-) -- 1.7.9.5
