DVD menus freezing in episode section since updating to v31

[Robert Worrall]

Hello,

Since updating to version 31 DVDs crash at the dvd episode selection screen. The output just before crashing is:

2020-03-29 22:01:05.111062 I AFD: Opened codec 0x7f81a406d5c0, id(DVD_SUBTITLE) type(Subtitle)
2020-03-29 22:01:05.111076 I AFD: Opened codec 0x7f81a4092440, id(DVD_SUBTITLE) type(Subtitle)
2020-03-29 22:01:05.111083 I AFD: codec AC3 has 2 channels
2020-03-29 22:01:05.111315 I AFD: Opened codec 0x7f81a406ee80, id(AC3) type(Audio)

2020-03-29 22:01:10.279233 I OpenGLInterop: Deleted 1 textures in 1 groups

is anyone else having this issue?

thanks

Rob.

I'm not seeing any crashes with DVD playback.

Can you get any more details?

Firstly a complete 'mythfrontend -v playback' log and ideally a backtrace when it crashes - are you using a packaged version or building from source? if from source, can you produce a debug build for the backtrace?

As a last resort, what DVD is it?

Thanks and regards
Mark

Hi Mark,

It seems to happen regardless of the DVD. Running the frontend with the playback log shows a number of repeated output:

020-04-28 22:37:15.670107 I OpenGLInterop: Deleted 1 textures in 1 groups
2020-04-28 22:37:15.670435 I VDPAUInterop: Setup deinterlacer '2x VDPAU Basic'
2020-04-28 22:37:15.672483 W DVDPlayer: In DVD Menu: No video frames in queue
2020-04-28 22:37:15.682620 W DVDPlayer: In DVD Menu: No video frames in queue
2020-04-28 22:37:15.692769 W DVDPlayer: In DVD Menu: No video frames in queue
2020-04-28 22:37:15.702912 W DVDPlayer: In DVD Menu: No video frames in queue
2020-04-28 22:37:15.713046 W DVDPlayer: In DVD Menu: No video frames in queue

This prompted me to try another render than VDPAU, which has fixed the problem, weird as I haven't had an update the NVIDIA driver. I might be something to do with the plasma desktop as I am on KDE neon. However when using another rendered the playback is now slowing. I am going to have a play about with the compositor and NVIDIA settings to see if this fixes the problem. In the meantime if you have any suggestions I would be grateful for any help.

Sorry, Mark. I also meant to say this from the ubuntu 31 repository.

To be clear - are you only seeing the issue with VDPAU enabled?

Can you post the full output from 'mythfrontend -v playback' from a crash?

thanks and regards
Mark

Hi Mark ,

Sorry for such a delay in coming back to you. I have tried to work this out myself but to no avail. I have put the full output into a file and attached it as it is too big to paste here.

Thanks again for your help.

Rob.

Another odd thing that is happening if I change the playback profile from VDPAU to anything else e.g 'High Quality' The audio is out of sync and playback is very slow. I have recently built a myth box for a friend and this is now doing the same regardless of setting. He does not have an nvidia GPU so can not use VDPAU. I have attached the output when using another profile any ideas what is going on.

Grateful as always.

I doubt this has any affect on your DVD playback but..
Your GT1030 is not listed (by Nvidia) as supported by the latest legacy driver 390..
Should be using 440.

Last DVD I played in MythTV was excellent (VDPAU & similar build to v0.31)

The whole linux desktop/Xorg is a train wreck.
Was better 10 years ago! Now it's all tearing & judder or a win3.1 interface.
It takes a lot of messing around to wrangle control over the compositing desktop managers in Mate/Gnome (& KDE prob.).
The unredirecting full screen is the problem.

The Nvidia driver has a setting that enables an OSD that reveals if it is using blitter (very bad for VDPAU) or overlay presentation mode.
(controlled in nvidia-settings)

Just a heads up for anyone having DVD issues with .31 whilst using VAAPI and/or VDPAU.

A fix went in yesterday - so please update and report back if there are still issues.

Thanks and regards
Mark
