HFI_VERSION_1XX uses HFI_BUFFER_OUTPUT not HFI_BUFFER_OUTPUT2 for decoder buffers. venus_helper_check_format() places a constraint on an output buffer to be of type HFI_BUFFER_OUTPUT2. HFI_1XX uses HFI_BUFFER_OUTPUT though. Switching to the logic used in venus_helper_get_out_fmts() first checking for HFI_BUFFER_OUTPUT and then HFI_BUFFER_OUTPUT2 resolves on HFI_1XX. db410c before: root@linaro-alip:~# v4l2-ctl -d /dev/video0 --list-formats ioctl: VIDIOC_ENUM_FMT Type: Video Capture Multiplanar [0]: 'MPG4' (MPEG-4 Part 2 ES, compressed) [1]: 'H263' (H.263, compressed) [2]: 'H264' (H.264, compressed) [3]: 'VP80' (VP8, compressed) root@linaro-alip:~# v4l2-ctl -d /dev/video1 --list-formats ioctl: VIDIOC_ENUM_FMT Type: Video Capture Multiplanar db410c after: root@linaro-alip:~# v4l2-ctl -d /dev/video0 --list-formats ioctl: VIDIOC_ENUM_FMT Type: Video Capture Multiplanar [0]: 'MPG4' (MPEG-4 Part 2 ES, compressed) [1]: 'H263' (H.263, compressed) [2]: 'H264' (H.264, compressed) [3]: 'VP80' (VP8, compressed) root@linaro-alip:~# v4l2-ctl -d /dev/video1 --list-formats ioctl: VIDIOC_ENUM_FMT Type: Video Capture Multiplanar [0]: 'NV12' (Y/CbCr 4:2:0) Validated playback with ffplay on db410c with h264 and vp8 decoding.
