[v3,00/15] Add MPEG-2 decoding to Rockchip VPU

Message

Boris Brezillon April 22, 2019, 8:08 a.m. UTC

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           │
└────────────────────────────────┘

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

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.

  rockchip/vpu: Rename rockchip_vpu_common.h into rockchip_vpu_v4l2.h
  rockchip/vpu: Remove a useless test
  rockchip/vpu: Move encoder logic to a common place
  rockchip/vpu: Provide a helper to reset both src and dst formats
  rockchip/vpu: Prepare things to support decoders

Ezequiel Garcia (9):
  rockchip/vpu: Use pixel format helpers
  rockchip/vpu: Use v4l2_m2m_buf_copy_metadata
  rockchip/vpu: Cleanup macroblock alignment
  rockchip/vpu: Cleanup JPEG bounce buffer management
  rockchip/vpu: Open-code media controller register
  rockchip/vpu: Support the Request API
  rockchip/vpu: Add decoder boilerplate
  rockchip/vpu: Add support for non-standard controls
  rockchip/vpu: Add support for MPEG-2 decoding
