Bug 1084677

Description of problem:

Playing videos using either mplayer or vlc using Xv output results in totally corrupted (unwatchable) videos. There are multiple "planes" of corrupted video moving on the video window, from different moments of time, and sometimes all video output also just stops, even though the player is still playing the video. 

Using unaccelerated x11 output, or OpenGL output, works fine, the problem seems to be only with Xv output. This is on a Lenovo T440s laptop with Intel Haswell CPU/GPU.

Version-Release number of selected component (if applicable):
xorg-x11-drv-intel-2.21.15-5.fc20.x86_64, Linux kernel 3.13.7-200.fc20.x86_64.

How reproducible:
Always.

Steps to Reproduce:
1. Try playing a video with mplayer or vlc using (default) Xv video output plugin: "mplayer video.mp4".

Actual results:
Video playback is all corrupted and unwatchable.

Expected results:
Video playback works OK, like it works with x11 or OpenGL output plugins.

Additional info:

$ rpm -qa | grep mplayer

$ rpm -qa | grep vlc
vlc-core-2.1.4-1.fc20.x86_64
vlc-2.1.4-1.fc20.x86_64


Example output from mplayer with the default Xv output (no errors visible, just corrupted output):

If I do "mplayer -vo gl" or "mplayer -vo x11" the same video file works perfectly OK.
