 |
|
When playing video on my 2015 MacBook air both VLC and mplayer are displaying grreen and pink artifacts all over in all. So far I have tested .AVI and .mkv formats. This is true for VLC 2.2.1 and 2.2.4, as well as mplayer 1.2.1 and 1.3.0. Here is an image of the artifacts.
Emerge -p output:

I'm using the intel i915 graphics driver, here is the lspci output:

Any ideas what is going on and how to fix it? Thanks!
EDIT:
Solved, the issue turned out to be with the default video output mode, xv. If I use x11 or gk2 playback works as expected.

Because it wasn't configured by default is the only real reason. I've never seen artifacts like this in other VLC installations withot hardware acceleration, but if you think lack of acceleration could be the cause of the artifacts I'd be willing to try it. |

The artifacts are not because you didn't enabled HW decoding, I suggested it because usually it is used when the GPU supports it.
Make sure you have everything set in make.conf:
https://wiki.gentoo.org/wiki/Intel#Driver
then re-merge xorg-server and xorg-drivers.
If this doesn't solve te issue, you can try modesetting for xorg:
https://wiki.gentoo.org/wiki/Intel#xorg.conf
or
Re-merge x11-drivers/xf86-video-intel with one of the three options enabled "glamor sna uxa". |
