I didn't drill down far enough to understand exactly what's wrong in decodebin.
It looks like it tries to grow the multiqueue multiple times as the H.264 queue
fills up, and the MPEG-2 queue underflows (because mpegvideoparse is just
discarding everything). Instead of actually growing the queue though, it sets
it to 2MB/5buffers repeatedly and never triggers overrun to expose the one
working stream.
