mjourdan-, I tested linuxtv master and your compliance patches, I see regression with iphone6s_4k.mov you gave me a while ago, kernel crash jernej: posted v3 of our series adding slicing support for cedrus. Please test! I realized while cleaning up my patch that is was easier to push the 'hold' handling down into the m2m framework. The cedrus patches are now very simple. o/ trying to figure out why my webcams keep failing to work in ubuntu 19.04. wonder if there's a way to use v4l2-dbg or something to get more insight cheese works perfectly, but qv4l2 doesn't after the first webcam play pH5, fyi, I've hacked away gst_kms_sink_sync() call in GStreamer, and see smooth playback on display controller here (RK3288), that's pretty good sign ndufresne: great, that does sound better than 'everything is green' :) indeed pH5, you also get "everything green" issue on IMX8M ? cause that's what I get on Panfrost with the CODEC buffers, while with vivid NV12, there is rendering artifact, but it's not full green ndufresne: not anymore, importing nv12 dmabufs into etnaviv works. but of course I had them on the way as well. could the vivid issue just be a missing cache flush? pH5, yes, panfrost is not currently doing any cache maintenance sorry, rebooted, if I missed a response :( it's well know, and in todo list pH5, but there is other issue, with both gst and weston shader, the UV plane looks scaled up by factor of 2 so we suspect a sampler bug but when buffers are from Hantro, solid green, no idea why right now I'm fixing gst so that we pass a modifier through wayland, that will give us plane passthrough anyway, bit off topic for this channel now, as soon as the userspace get a tad more stable, it will be easier to point toward hantro driver for some issues I see
