It features decoding for the following formats: - MPEG 1 - MPEG 2 The following formats will be added in future patches: - MJPEG - MPEG 4 (incl. Xvid, H.263) - H.264 - HEVC (incl. 10-bit) The following formats' development has still not started, but they are supported by the hardware: - VC1 - VP9 The code was made in such a way to allow easy inclusion of those formats in the future. The decoder is single instance. Files: - vdec.c handles the V4L2 M2M logic - esparser.c manages the hardware bitstream parser - vdec_helpers.c provides helpers to DONE the dst buffers as well as various common code used by the codecs - vdec_1.c manages the VDEC_1 block of the vdec IP - codec_mpeg12.c enables decoding for MPEG 1/2. - vdec_platform.c links codec units with vdec units (e.g vdec_1 with codec_mpeg12) and lists all the available src/dst formats and requirements (max width/height, etc.), per compatible chip. Firmwares are necessary to run the vdec. They can currently be found at: https://github.com/chewitt/meson-firmware It was tested primarily with ffmpeg's v4l2-m2m implementation. For instance: $ ffmpeg -c:v mpeg2_v4l2m2m -i sample_mpeg2.mkv -f null - Note: This patch series depends on "[PATCH v3 0/3] soc: amlogic: add meson-canvas" https://patchwork.kernel.org/cover/10573763/ This canvas series is merged in Kevin Hilman's tree with a tag: Repo: https://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic.git Tag: amlogic-drivers-canvas The v4l2-compliance results are available below the patch diff. Changes since v2 [1]: - Override capture queue's min_buffers_needed in queue_setup The HW needs the full buffer list to be available when doing start_streaming - Fix the draining sequence The blob that we write to the ESPARSER to trigger drain is codec-dependent. The one that was sent in v1 is specific to H.264 and isn't guaranteed to trigger drain for MPEG2. For the latter, a simple MPEG2 EOS code should be sent to the ESPARSER instead. - Slight enhancements to the way we do vififo offset<=>timestamp matching Changes since v1 [0]: - use named interrupts in the bindings - rewrite description in the bindings doc - don't include the dts changes in the patch series - fill the vb2 queues locks - fill the video_device lock - use helpers for wait_prepare and wait_finish vb2_ops - remove unnecessary usleep in between esparser writes. Extensive testing of every codec on GXBB/GXL didn't reveal any fails without it, so just remove it. - compile v4l2_compliance inside the git repo - Check for plane number/plane size to pass the latest v4l2-compliance test - Moved the single instance check (returning -EBUSY) to start/stop streaming The check was previously in queue_setup but there was no great location to clear it except for .close(). - Slight rework of the way CAPTURE frames are timestamped for better accuracy -
