But does this mean it does encoding aswell?

I am not sure where I can find a version of ffmepg that supports the cedrus driver and that works with the some form of modern version of ffmpeg source tree. Anyone who knows?

Okay, I have the driver loaded: root@orangepizero2w:/boot# dmesg | grep cedrus [ 8.578154] sunxi_cedrus: module is from the staging directory, the quality is unknown, you have been warned. [ 8.580382] cedrus 1c0e000.video-codec: Device registered as /dev/video2 I also did this: root@orangepizero2w:/boot# v4l2-ctl --all --device /dev/video2 Driver Info: Driver name : cedrus Card type : cedrus Bus info : platform:cedrus Driver version : 6.1.31 Capabilities : 0x84208000 Video Memory-to-Memory Streaming Extended Pix Format Device Capabilities Device Caps : 0x04208000 Video Memory-to-Memory Streaming Extended Pix Format Media Driver Info: Driver name : cedrus Model : cedrus Serial : Bus info : platform:cedrus Media version : 6.1.31 Hardware revision: 0x00000000 (0) Driver version : 6.1.31 Interface Info: ID : 0x0300000c Type : V4L Video Entity Info: ID : 0x00000001 (1) Name : cedrus-source Function : V4L2 I/O Pad 0x01000002 : 0: Source Link 0x02000008: to remote pad 0x1000004 of entity 'cedrus-proc' (Video Decoder): Data, Enabled, Immutable Priority: 2 Format Video Capture: Width/Height : 16/32 Pixel Format : 'ST12' (Y/UV 4:2:0 (32x32 Linear)) Field : None Bytes per Line : 32 Size Image : 2048 Colorspace : Default Transfer Function : Default (maps to Rec. 709) YCbCr/HSV Encoding: Default (maps to ITU-R 601) Quantization : Default (maps to Full Range) Flags : Format Video Output: Width/Height : 16/32 Pixel Format : 'MG2S' (MPEG-2 Parsed Slice Data) Field : None Bytes per Line : 0 Size Image : 1024 Colorspace : Default Transfer Function : Default (maps to Rec. 709) YCbCr/HSV Encoding: Default (maps to ITU-R 601) Quantization : Default (maps to Full Range) Flags : Codec Controls h264_profile 0x00990a6b (menu) : min=0 max=4 default=2 value=2 (Main) 0: Baseline 1: Constrained Baseline 2: Main 4: High Stateless Codec Controls h264_decode_mode 0x00a40900 (menu) : min=0 max=0 default=0 value=0 (Slice-Based) 0: Slice-Based h264_start_code 0x00a40901 (menu) : min=0 max=0 default=0 value=0 (No Start Code) 0: No Start Code h264_sequence_parameter_set 0x00a40902 (h264-sps): value=unsupported payload type flags=has-payload h264_picture_parameter_set 0x00a40903 (h264-pps): value=unsupported payload type flags=has-payload h264_scaling_matrix 0x00a40904 (h264-scaling-matrix): value=unsupported payload type flags=has-payload h264_prediction_weight_table 0x00a40905 (h264-pred-weights): value=unsupported payload type flags=has-payload h264_slice_parameters 0x00a40906 (h264-slice-params): value=unsupported payload type flags=has-payload h264_decode_parameters 0x00a40907 (h264-decode-params): value=unsupported payload type flags=has-payload vp8_frame_parameters 0x00a409c8 (vp8-frame): value=unsupported payload type flags=has-payload mpeg_2_sequence_header 0x00a409dc (mpeg2-sequence): value=unsupported payload type flags=has-payload mpeg_2_picture_header 0x00a409dd (mpeg2-picture): value=unsupported payload type flags=has-payload mpeg_2_quantisation_matrices 0x00a409de (mpeg2-quantisation): value=unsupported payload type flags=has-payload hevc_sequence_parameter_set 0x00a40a90 (hevc-sps): value=unsupported payload type flags=has-payload hevc_picture_parameter_set 0x00a40a91 (hevc-sps): value=unsupported payload type flags=has-payload hevc_slice_parameters 0x00a40a92 (hevc-slice-params): elems=1 dims=[1] flags=has-payload, dynamic-array hevc_scaling_matrix 0x00a40a93 (hevc-scaling-matrix): value=unsupported payload type flags=has-payload hevc_decode_parameters 0x00a40a94 (hevc-decode-params): value=unsupported payload type flags=has-payload hevc_decode_mode 0x00a40a95 (menu) : min=0 max=0 default=0 value=0 (Slice-Based) 0: Slice-Based hevc_start_code 0x00a40a96 (menu) : min=0 max=0 default=0 value=0 (No Start Code) 0: No Start Code hevc_entry_point_offsets 0x00a40a97 (u32) : min=0 max=4294967295 step=1 default=0 elems=1 dims=[256] flags= has-payload, dynamic-array I take that the driver is loaded successfully then, so the next step would be to build ffmpeg with cedrus support?

Thanks everyone for the answers! Upon looking at the many patches you posted there going, this one sticks out for me https://github.com/armbian/build/blob/main/patch/kernel/archive/sunxi-6.13/patches.armbian/arm64-dts-allwinner-sun50i-h616-Add-VPU-node.patch Maybe that one would work for H618 also to enable the VPU? Would that patch in itself be sufficient to compile and enable the cedrus-driver?

I have not seen any one of them do it, but I assume they possess that capability since it is mentioned in the datasheet for H616 here: https://linux-sunxi.org/images/b/b9/H616_Datasheet_V1.0_cleaned.pdf I am looking for a DTS that has the correct parameters for the cedar driver (correct registers, memory etc) for the H618. I am absolutely open to doing a DTS overlay if that would make work easier.

Hello! I am trying to get the cedar_ve device working for OPIZ2W. I am currently running this image: Orangepizero2w_1.0.4_ubuntu_noble_server_linux6.1.31 My uname -a: Linux orangepizero2w 6.1.31-sun50iw9 #1.0.4 SMP Wed Oct 9 13:39:53 CST 2024 aarch64 aarch64 aarch64 GNU/Linux To do this I am trying to follow these steps: 1. Modify a dts for OPIZ2W to include cedar_ve. 2. Donwloan cedrus driver and build it. 3. Compile modified ffmpeg with x264cedrus support Have anyone tried this? I have only found builds for recent kernel for the H3 CPU, none for the H618. I am looking for a DTS that supports cedar_ve for Orange Pi Zero 2W or any other things that can point me in the right direction.
