I'll have to look into it, and just in case you see a problem on first sight: this is what coda says with debug level 1, when doing gst-launch-1.0 playbin uri=file:///data/test2_hd480.h264 video-sink=fbdevsink A bit unrelated, but kmssink remains a better choice here. True, but I'm currently not yet interested in the other end of the pipe :) Decoding works in principal. VDOA is still disabled however :( I don't see what I can do about this right now, which is a bit odd. It is definitely probed (and not removed). I see at least a few frames of the video, so I guess the video file is fine? Or could it be a file (or pixel) format that isn't supported? Again, ffprobe says Stream #0:0: Video: h264 (High), yuv420p(progressive), 852x480, 24 fps, 24 tbr, 1200k tbn, 48 tbc thanks After this, I want to have video conversion (color space) via a v4l2 interface that in turn uses the imx6 IPU. I guess gst-inspect-1.0 should see a V4L2 Converter, which it currently doesn't here: # gst-inspect-1.0 | grep v4l2 video4linux2: v4l2video1dec: V4L2 Video Decoder video4linux2: v4l2deviceprovider (GstDeviceProviderFactory) video4linux2: v4l2radio: Radio (video4linux2) Tuner video4linux2: v4l2sink: Video (video4linux2) Sink video4linux2: v4l2src: Video (video4linux2) Source # dmesg | grep ipu [1.394717] imx-drm display-subsystem: bound imx-ipuv3-crtc.2 (ops 0xc07d4b60) [1.402258] imx-drm display-subsystem: bound imx-ipuv3-crtc.3 (ops 0xc07d4b60) [1.514984] imx-ipuv3 240.ipu: IPUv3H probed should imx-ipuv3 provide a video4linux2 interface for video conversion? At least I don't see it yet. (or other V4L2 Linux config options than I already have enabled)

I'll still need to took into the v4l2 interface for the imx6 IPU) (imx6, running linux 4.14-rc3, imx-vdoa is probed and never removed, a dev_info "probed" would maybe be useful for others too?) It supsequently fails with cma: cma_alloc: alloc failed, req-size: 178 pages, ret: -12 That is -ENOMEM. Is CMA enabled and sufficiently large? For example, CONFIG_CMA=y CONFIG_CMA_DEBUGFS=y CONFIG_DMA_CMA=y CONFIG_CMA_SIZE_MBYTES=256 CONFIG_CMA_SIZE_SEL_MBYTES=y My cma buffer size was indeed just too small.
