Currently, support for IMX8QXP and IMX8QM is included. It features decoding for the following formats: - H.264 - HEVC - MPEG4 - MPEG2 - VC1 - VP8 It features encoding for the following formats: - H.264 The driver creates a separate device node for the encoder and decoder. This driver is dependent on vpu firmwares. The firmwares have been submitted to linux-firmware. The firmware patch is since commit b563148fd28623f6b6ce68bb06c3dd3bd138b058: linux-firmware: Update firmware file for Intel Bluetooth 9462 (Fri Oct 8 16:30:14 2021 +0530) and it's available in the git repository at: https://github.com/mingqian-0/linux-firmware.git for you to fetch changes up to bb3eee4f99589d4910dee4c053a3a685546b5dbb: amphion: add VPU firmwares for NXP i.MX8Q SoCs (Tue Oct 12 15:09:57 2021 +0800) encoder is tested with gstreamer decoder is tested with gstreamer, but the following patches are required: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1379 https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1381 Tested-by: Nicolas Dufresne Changelog: v14 - fix some errors according to Hans's comments v13 - make a workaround that avoid firmware entering wfi wrongly v12 - support reset decoder when starting a new stream - don't append an empty last buffer, set last_buffer_dequeued - improve the resolution change flow - return all buffers if start_streaming fail - fill encoder capture buffer's filed to none - fix a bug in calculating bytesperline v11 - fix dt_binding_check error after upgrade dtschema - remove "default y" - add media device v10 - refine vpu log, remove custom logging infrastructure - support non contiguous planes format nv12m instead of nv12 - rename V4L2_PIX_FMT_NV12_8L128 to V4L2_PIX_FMT_NV12MT_8L128 - rename V4L2_PIX_FMT_NV12_10BE_8L128 to V4L2_PIX_FMT_NV12MT_10BE_8L128 - merge two module into one - fix kernel panic in rmmod v9 - drop V4L2_BUF_FLAG_CODECCONFIG - drop V4L2_EVENT_CODEC_ERROR - drop V4L2_EVENT_SKIP - use the v4l2_buffer.sequence counter - fix some build warnings with W=1 reported by kernel test robot v8 - move driver from driver/media/platform/imx/vpu-8q to driver/media/platform/amphion - rename driver name to amphion - remove imx_vpu.h - move the definition of V4L2_EVENT_CODEC_ERROR to videodev2.h - move the definition of V4L2_EVENT_SKIP to videodev2.h v7 - fix build warnings with W=1 reported by kernel test robot v6: - rename V4L2_PIX_FMT_NT8 to V4L2_PIX_FMT_NV12_8L128 - rename V4L2_PIX_FMT_NT10 to V4L2_PIX_FMT_NV12_10BE_8L128 v5: - move some definition from imx_vph.h to videodev2.h - remove some unnecessary content - add some documentation descriptions - pass the lateset v4l2-compliance test v4: - redefine the memory-region in devicetree bindings documentation - use v4l2's mechanism to implement synchronize queuing ioctl - remove the unnecessary mutex ioctl_sync - don't notify source change event if the parameters are same as previously established - add flag V4L2_FMT_FLAG_DYN_RESOLUTION to decoder's capture format v3: - don't make vpu device node a simple-bus - trigger probing vpu core in the driver - remove unnecessary vpu core index property v2: - fix dt bindings build error - split driver patch into several parts to avoid exceeding bytes limit Compliance ========== # v4l2-compliance -d /dev/video0 v4l2-compliance
