VDPAU TNT Stream Rendering Problem
#1
Hi everybody.

I post this message here, because i have no answer on openelec forum and maybe it is more on vdpau implementation than on openelc itself.

I have some issues with TNT stream (using hdhomerun + tvheadend). (i have ION2 chipset - XS35GT + openelec 4.0.6)
It seems that on an unperfect TNT reception, VDPAU playback doen't deal very well with it.
I have recording a short TNT stream and made several tries :
- playback on openelec + VDPAU acceleration => KO
- playback on openelec + sofware => OK
-playback on PC W7 (NVIDIA) + XBMC + DXVA2 => OK
-playback on nexus 7 with HW acceraltion : OK

So my conclusion is that VDPAU implementation has probleme with imperfect stream such TNT.

Have you ever met this issue / or got solution with some tricks ?

You can download the original stream and what i see with HW acceleration and softwawre + xbmc.log . :
dl.free.fr/ckjOedn9S or mon-partage.fr/f/Sh4RCeQJ/

the stream (source.mkv) has been tested on intel and it's ok.

I tested your sample here. On an NVidia system I get the same result as you showed in the video. On an AMD system (also vdpau) it looks much better.
Means this an NVidia issue, not vdpau in general. You should post this on NVidia forum.

Hi,

on an nvidia under windows it's OK. So maybe linux driver then.
