Does Aegisub actually crash? As in, after the error appears the program completely closes.
If Aegisub continues running and functioning after the error is shown, it's not crashing, even if opening video has failed.
Please find out these things:
- If the error happens with all videos or only some videos; try using Dummy Video to test both SD and HD resolutions
- Your graphics card (graphics chipset) manufacturer, usually NVidia, AMD or Intel
- Your graphics driver version
- Your OS version, e.g. Windows 7, Windows 8, Mac OS 10.9, Ubuntu 14.10, or whatever
Do not PM me asking for help with Aegisub, Automation, karaoke or anything like that, I won't reply.
