Description
I have a playlist of two producers. This first is just a png file, and the second is an mkv video blended with a png, using frei0r.cairoblend. If I use an avfile consumer, it works fine, but if I use the sdl2 consumer I get only audio from the mkv (or at least that's what it looks like). If I swap the order of the consumers in the playlist, it works in the SDL consumer as well. I will attach the test case.

Research direction
Start by reproducing the behavior with the attached test-case.zip, comparing the avfile and sdl2 consumers and both playlist orders. Trace the consumer path responsible for video output; done means the SDL2 consumer renders the MKV video regardless of producer order while preserving the working audio behavior.
