Retroplayer crashes for OpenGL based cores

[BullShark]

Bug report

Describe the bug

Trying to launch any Nintendo 64 game from IAGL add-on in Kodi results in Kodi crashing.

Expected Behavior

Launch the game in mupen64 emulator after downloading the game.

Actual Behavior

Crashes Kodi with a seg fault

Possible Fix

I suspect that the addons work without crashing Kodi in older versions of Kodi.

To Reproduce

Steps to reproduce the behavior:
Here's the steps I took.

Install all of these using yay.

Install kodi-x11
Install kodi-addon-game-libretro
Install kodi-addon-game-libretro-mupen64plus

Download the IAGL zipfile

In Kodi:

Add the zipfile to get the repo.
Install IAGL from the new repo.
Install Nintendo 64 Controller
Nintendo - Nintendo 64 (Muphen64Plus)
Install IAGL - Internet Archive Game Launcher

In Kodi:

IAGL -> Browse All Lists -> Internet Archives Best Of N64 -> The Legend of Zelda - Ocarina of Time or 007

It seems to happen with every Nintendo 64 game.

Results:
Crashes Kodi every time.

$ kodi --debug

Crash report available at /home/bullshark/kodi_crashlog-20200615_004443.log

Is the save file being opened before checking if it exists? And a save file is expected the first time a game is ran when there has been no saves.

Just before the crash:

The crash happens immediately after the download for any N64 game.

Your Environment

Used Operating system:
Manjaro Linux with KDE latest.

I created a .sav file and saved it where it was being looked for. That didn't prevent the crash.

I opened the same game in M64Py, a gui frontend to mupen64, and it opened the game without error.

kodi doesn't support opengl and all the libretro n64 emus use opengl. use iagl to launch retroarch or a different emu and it should work

I've been trying that. I haven't been able to get it to work. Can you help?

The game works in retroarch launched without kodi just fine.

[BullShark]

Is it possible that Kodi is calling retroarch without passing the -L flag?

This works.
retroarch -f -L /usr/lib/libretro/parallel_n64_libretro.so Game.n64

This does not work. Retroarch will fail to launch.
retroarch -f Game.n64

I cannot tell what arguments IAGL is passing to Retroarch when trying to launch the game. I tried creating a wrapper script in bash for IAGL to launch Retroarch with the -L /path/to/emulator_libretro.so and had no luck with it yet.

This is a Kodi issue, reference xbmc/xbmc#15874.

Launching externally works. See here for troubleshooting tips on external launching.

[zach-morris]

I've updated the title of this issue just so people are aware of the state of this.

Kodi currently doesn't support OGL only cores, such as N64. I think the target is v20 Kodi for this. See here.

There's nothing IAGL can do to make Retroplayer work for these since it's Kodi functionality. For these game lists, you have to launch them externally (or hide them for now).
