Hi, I'm trying to use hardware acceleration on my OrangePi PC+ (H3) board, and when I try to compile v4l2-request, it complains for undefined constants. These constants are supposed to be declared in /usr/include/linux/videodev2.h, but looks like a very old version of this file is distributed in the latests Armbian images for my board. Some missing headers: V4L2_PIX_FMT_MPEG2_SLICE, V4L2_PIX_FMT_SUNXI_TILED_NV12 Looks like these #define have been introduced more than two years ago in the mainline kernel : https://github.com/torvalds/linux/blame/d5beb3140f91b1c8a3d41b14d729aefa4dcc58bc/include/uapi/linux/videodev2.h#L698 Even more weird: a later version (with the defines I need) of this file was available earlier in Armbian 20.05 (kernel 5.4.43) I found in the archived versions. Hope that to be fixed, and maybe one day have Armbian with hardware acceleration working out of the box

Hi, I'm trying to build that v4l2-request source code, on OrangePi PC+ (H3) but it seems that there area lot of undefined macro from linux/videodev2.h . Looks like this file is outdated even if I get the last daily armbian image. How did you manage to compile it? among others, missing defines are: V4L2_PIX_FMT_SUNXI_TILED_NV12 V4L2_PIX_FMT_MPEG2_SLICES inserted by https://github.com/torvalds/linux/commit/c27bb30e7b6d385c5bff26406089377d678f1a1d on mainline kernel source code Cheers, Will'
