Need help folks, did a search and couldn't find this exact issue and a resolution (sorry if it's been discussed). I have a Radeon HD 5770 and just did a fresh install of Linux Mint 17.1. First thing I did before installing Kodi was update the OSS drivers with the "Updated and Optimized Open Graphics Drivers" found on the Oibaf PPA found at:

https://launchpad.net/~oibaf/+archive/ub...cs-drivers

After adding the PPA I also did a "sudo apt-get install mesa-vdpau-drivers" and set up Kodi to use the VDPAU hardware acceleration. But when I attempt to play a video Kodi crashes to the desktop. Any tips or suggestions?

Remove those drivers. Everything > 10.4.x is broken and upstream knows.

Edit: https://bugs.freedesktop.org/show_bug.cgi?id=86837 <- upstream bug report

Hi fritsch, I did a "sudo ppa-purge ppa:oibaf/graphics-drivers" last night but Kodi still crashes. :/

I'll do some more digging, hopefully future updates to the drivers and/or Kodi will resolve this.

No crash without a crashlog
Edit: And no bug without a Debug Log

Last few lines of the kodi_crashlog say:

Grrr - I hate that, cut logfiles, all information missing ... what was so hard when reading Debug Log ?

your driver installation is foobar - fix that.

Verify it with:

vdpauinfo | pastebinit - if that works, kodi will also work.

I updated the OS to kernel 3.18.3. After a bit of fiddling Kodi is now using VDPAU hardware acceleration, however sometimes the video doesn't feel as "fluid" as it should with some minor sputters and a few dropped frames.

Provide what I requested above!
