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.
