Thx. already integrated it into my tree - works fine :) By the way: i still have some your older patches (2012) in my tree, eg. some mediabus, camara, display timing stuff, etc ... not sure whether I really need them for my device. Should I post them to linux-media list for review ? Oh, and I also still have your famous DRM_IOCTL_MODE_MAP_DUMB hack (the "Reluctantly-signed-off-by:" one ;-), meanwhile rebased / adapted into 4.x. Do you have any idea, what the amd-gpu driver/library exactly does with the retrieved address ?

I played around a little bit - this command line only takes 55% cpu: gst-launch-1.0 filesrc location=3Dmontage.mp4 \! qtdemux \! h264parse \! v4l2video4dec output-io-mode=3D4 capture-io-mod= e=3D4 \! v4l2 video0convert capture-io-mode=3D4 output-io-mode=3D5 \! fbdevsink By the way: what's the exact difference between dmabuf and dmabuf-import ? > > By the way: do you have any idea whether the proprietary driver > > (or the gpus itself) might talk to ipu and vpu ? > > Not that I am aware of. Well, you perhaps can imagine - I dont trust these guys ... --mtx ps: greetings from Bene ... you won't guess where I met him last weekend ;-) -- Enrico Weigelt, metux IT consult +49-151-27565287 MELAG Medizintechnik oHG Sitz Berlin Registergericht AG Charlottenburg = HRA 21333 B Wichtiger Hinweis: Diese Nachricht kann vertrauliche oder nur f=C3=BCr = einen begrenzten Personenkreis bestimmte Informationen enthalten.
