I've been testing 4.14-rc4 on Odroid-XU4, and here's a kernel complaint when running: gst-launch-1.0 filesrc location=bunny_trailer_1080p.mov ! parsebin ! v4l2video4dec capture-io-mode=dmabuf ! v4l2video6convert output-io-mode=dmabuf-import capture-io-mode=dmabuf ! kmssink http://paste.debian.net/990353/ PS: on kernel 4.9 patched with MFC & GSC updates (almost up to date with 4.14 I think) there was no "Wrong buffer/video queue type (1)" message either Either I've been missing something or nothing has been going on.
