Created attachment 131725 [details] Adobe video speed failure System Environment ======= OS: Linux Ubuntu 17.04 64 bits Kernel: 4.12.0-rc3-drm-tip-ww2-commit-187376e+ X-Org: 1.19.99.1 Regression? ======= No Bug detailed description ======= Embedded content derived from Adobe products plays at a high rate of speed, disregarding if the video has been buffered or not, it will play at high speed. Videos have frame rate issues as they seem to get stuck momentarily (specially with the FLV/SWF formats), the higher the resolution, the heavier the problem (chopped playback) Reproduce Steps ============== Open a video (streamed or local), from 720p resolution and up Expected Result ============= It should play at normal speed. Actual Result =========== Plays intermittently at different frame rates with a regular frame drop every one or two seconds and, in the case of FLV/SWF videos it plays at a 2X - 3X playback rate when not chopped or stuck. Analysis & Root Cause =================== Possible and maybe required bottleneck detection within the graphics stack (even per-output port display sequencing), improper buffer usage. It may happen due to the fact of the audio clocks being misconfigured that the video couldn't find a correct speed value to display the required amount of textures buffered, however, this is a totally different behavior while using x264 or other video codecs, it seems to fail only with Adobe derived video content.
