--- Comment #10 from mkrsym1@gmail.com --- Looking at the MR, I believe it needs to be said that the stream in question is actually neither nal-aligned, nor au-aligned. A nal-aligned stream would not have NALUs split across buffers, which happens here, and is correctly handled both by Windows, and by h264parse if alignment is not specified.
