Hi Hans, The patches are indeed based on linux-media kernel, and the V4L2_COLORSPACE_GENERIC_FILM is added in the patch "media: v4l: add some definition of v4l2 colorspace/xfer_func/ycbcr_encoding", which is the second patch of these series. > > On 20/07/2021 03:43, Ming Qian wrote: > > Hi all, > > > > This patch series adds support for > > the imx8q video encoder and decoder > > via the VPU block present in imx8q platforms. > > Currently, support for IMX8QXP and IMX8QM is included. > > > > It features decoding for the following formats: > > - H.264 > > - HEVC > > - MPEG4 > > - MPEG2 > > - MJPEG > > - VC1 > > - VP8 > > - AVS > > > > It features encoding for the following formats: > > - H.264 > > > > The driver creates a separate device node for the encoder and decoder. > > > > Changelog: > > > > 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 SHA: not available > > , 64 bits, 64-bit time_t > > Always compile v4l2-compliance from the git repo > (https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgit.linu > xtv.org%2Fv4l-utils.git%2F&data=04%7C01%7Cming.qian%40nxp.com%7 > C3b39b6df4e6746d5e5c308d94c19dd55%7C686ea1d3bc2b4c6fa92cd99c5c3 > 01635%7C0%7C1%7C637624496237171229%7CUnknown%7CTWFpbGZsb3d > 8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3 > D%7C2000&sdata=%2FWh5ObGzfWN%2B2z4J9qhuM7bpA%2Fd6iaZbJw > QhMI%2FdzFI%3D&reserved=0). > Otherwise I cannot tell whether it is a recent version or if it is old.
