Michael Fabian 'Xaymar' Dirks cfc828f0f8 source-mirror: Fix crash with audio sources and late video sources
Source Mirror would incorrectly crash if an Audio only source was selected, as it expected a video frame to be present of any size. This fixes the problem by first testing if there is any video information to render and then just catching any exception that happens during rendering.
