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.

Reproduce Steps
 ==============
 Open an FLV/SWF streaming website (YouTube, NewGrounds) and open any video at any desired resolution.

Expected Result
 =============
 It should play at normal speed.

Actual Result
 ===========
 Plays at something around 2X to 3X times the normal speed.

Analysis & Root Cause
 ===================
 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.

Bug is invalid, this behavior and more can be found at a more generic-level bug
