[mythtvnz] Channel change stability issues with MythTV and VDPAU in NZ

[Steve V]

Hi Steve,

I want to see if I can replicate this issue with my system.. Just to keep the variables similar - when you change channels do you wait for the new channel to show before selecting another channel or do you just keep pushing channel number buttons until the frontend exits.

Cheers

Steve

I've finally got a debug dumps from a recent Jean-Yves MythTV build that shows the two issues I'm regularly seeing with VDPAU playback of freeview|HD here in NZ.

1. MythTV frontend exits during a channel change

Test environment
    * Ubuntu 8.10 32bit
    * NVidia VDPAU 185.19
    * mythtv - 1:0.21.0+fixes-20550-openglvdpau-debug-0ubuntu2 

You can find the debug files here

http://www.mythtv.co.nz/shared/vdpau/channel_crash/myth.log

To produce the problem I select a freeview|HD only channel, and then change between random channels reasonably quickly until the frontend exits, or I hit my other issue shown below.


I've now reproduced the frontend crash problem with an updated build

Test environment
    * Ubuntu 8.10 32bit
    * NVidia VDPAU 185.18.14
    * mythtv - 1:0.21.0+fixes-20649-openglvdpau-debug-0ubuntu2
