Comment (by John Coiner):

 Thanks Balling. I've substituted M2TS with TS in the description.

 To be clear, the problem concerns "ingestions" -- Live uploads to YouTube.
 For these, YouTube doesn't decide when the resolution changes -- the
 content creator does. I suspect YouTube supports resolution changes in the
 middle of an HLS ingestion and even in the middle of an HLS chunk, but
 haven't tested this. Certainly, we should not do anything that would
 preclude this.

 I'm not sure how the posted patch would preclude a change of resolution;
 could you elaborate on the sequence you're concerned about? Thanks.
