"Cannot create EGLImage" error when setting DMA-BUF source
sserenade opened this issue · comments
Just in case this is still being worked on:
After working around #16, I was able to build it properly (& enabled debug).
However, when selecting the DMA-BUF source, I don't get any video. The log shows error: Cannot create EGLImage: 12296:

Where 12296 appears to correspond to EGL_BAD_DISPLAY. When debugging with gdb, it seems the value returned by graphics->device->plat->edisplay in dmabuf.c is a generic pointer, unlike the xdisplay value. I attempted to use eglGetDisplay here, but it failed as well.
Would be very happy to be told I'm missing something, as I would love to try out the benefits of this fork, despite the state it is in.
Maybe I should have enabled OpenGL EGL in video settings :)
