Apparently, this hang can be fixed at small performance cost by setting NOUVEAU_VP3_DEBUG_FENCE 1 (as opposed to default 0) in https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/nouveau/nouveau_vp3_video.h Now, what exactly fixes my hangs (or make them less severe) - still open question, guess I can flip few of those debug defines and try to find out ... Currently at mesa Mesa 20.3.0-devel (git-8557b1a8eb) I can launch two of those VIDEO: [H264] 1920x1080 0bpp 59.940 fps and it will not hang Even survived 5 x 1080p h264 (30 fps) videos - it was slideshow (due to DRI_PRIME ?) but it does not hang .... _______________________________________________ Nouveau mailing list Nouveau@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/nouveau
