This series introduces the decoding infrastructure that will be used to add support for other codecs such as VP8, VP9 and H.264. As explained in the cover letter for the v1 patchset, the driver is now exposing two video device nodes. The VPU encoder is exposed on /dev/video0, and the VPU decoder is exposed on /dev/video1. Both devices are tied to the same memory-to-memory queue, and same media device /dev/media0. Therefore there are two media graphs: ┌────────────────────────────────┐ │ rockchip,rk3399-vpu-enc-source │ │ /dev/video0 │ └────────────────────────────────┘ ┃ ┃ ▼ ┌────────────────────────────────┐ │ rockchip,rk3399-vpu-enc-proc │ └────────────────────────────────┘ ┃ ┃ ▼ ┌────────────────────────────────┐ │ rockchip,rk3399-vpu-enc-sink │ │ /dev/video0 │ └────────────────────────────────┘ ┌────────────────────────────────┐ │ rockchip,rk3399-vpu-dec-source │ │ /dev/video1 │ └────────────────────────────────┘ ┃ ┃ ▼ ┌────────────────────────────────┐ │ rockchip,rk3399-vpu-dec-proc │ └────────────────────────────────┘ ┃ ┃ ▼ ┌────────────────────────────────┐ │ rockchip,rk3399-vpu-dec-sink │ │ /dev/video1 │ └────────────────────────────────┘ Of course, this work has been possible thanks to Jonas Karlman, who did the initial MPEG-2 decoding work and also got mpv+ffmpeg working using the Request API. Regards, Boris v4: * Fix issues in the probe/remove path preventing the driver from being unloaded/reloaded (Jonas) * Rework the media controller registration code to simplify the error/remove path (Boris) * Split the MPEG2 patches (one adding the generic code and one patch per platform) v3: * Share more code between the encoder/decoder logic (VB2/V4L2 interface implementation) * Add a patch to support MPEG2 decoding on RK3288 (Jonas) * Several fixes/improvements all over the place (see changelog in each patch for more details) v2: * Fixed some minor issues brought up by v4l2-compliance. * Fixed bytesused wrongly assigned 0 on the MPEG-2 decoder. * Addressed comments from Hans and Tomasz on the pixel format helpers.
