Export using codec hevc_qsc failed

I strongly discourage that. I am not actively working on this bug and may never since it only affects Intel QSV on Windows at specific low resolutions. That suggests it is not something in our code but possible something in a library or driver. I am simply not interested in pursuing it myself, but here it is for another open source adventurer. In the meantime, this is SD resolution, which is not lengthy to encode with software, and you should use it. You see? An hour is already passed, and you could have been done.
