testffmpeg default (gles EGL) fails
using the default selected renderer with testffmpeg, output fails.
manually disabling with SDL_VIDEO_FORCE_EGL=0 works
es2gears_x11, eglgears_x11, xeglgears, and glxgears from https://gitlab.freedesktop.org/mesa/demos/-/tree/main all run without issue

I can't reproduce this here, does it fail the same way for the other SDL test programs, e.g. testsprite?
No response, I'll go ahead and close this for now. Please let us know if it's still an issue.
@slouken sorry for the delay. testdraw and testsprite have no issues but I believe this is because they are using the Vulkan render. testgles2, testgl also work. So seems like an issue unique to the EGL implementation that I guess none of the other tests implement or use.
testsprite --renderer opengles2 should have the same codepath as testffmpeg?
testsprite --renderer opengles2should have the same codepath as testffmpeg?
No issues with that. Can confirm that is actually using opengles2 so the options are working. It doesn't seem like the same EGL path is being used in these other tests.
Okay, well please let us know if you find out what's different about testffmpeg.
The whole thing (https://github.com/libsdl-org/SDL/blob/bf54eddba964a9d27723c9d958ff889f1fcf4a89/test/testffmpeg.c#L109-L135) is different from the other tests. I don't understand why testffmpeg is its own thing and doesn't use SDL_test_common.c as a base like all the other tests. I don't see why you are implementing stuff differently here.
