Description Jeff 2015-12-10 13:30:46 UTC

Hi

I have a AMD HD4225 graphics card with the RS880M chip.

https://en.wikipedia.org/wiki/AMD_800_chipset_series#Desktop_and_Mobile

vdpauinfo shows that it should have vdpau support for mpeg2 (whether in the UVD or in the shaders I don't know).

However it (vdpau) does not work on mythfrontend, mpv or mplayer.

Do you know if the r600 driver is still being worked on for vdpau support? Does anyone know if this is a known issue? I wasn't able to find anything in the bug reports.

Thanks
 Jeff

PS. I will provide more logs when I am home and can access my computer if anyone thinks they will help.

Additionally I should say it works great for h264.

The MPEG2 support is shader based and IIRC, I think myth at least disables it since it's problematic.

Kodi, Myth, Mpv and mplayer all allow me to select it. Right now I am using software decoding, but I'd like to off load some of the processing to the GPU. (primarily for deinterlacing)

It is listed in vdpauinfo as having mpeg-2 support.
