Comment (by Ace17):

 I seems so, because the mpegts muxer is under different conditions:

 A) AVPacket.pts and AVPacket.dts are fully specified,
 av_interleaved_write_frame doesn't report any error, and the output
 transport stream has invalid DTS values.

 B) AVPacket.pts and AVPacket.dst are not specified,
 av_interleaved_write_frame reports an error and no output file is

 Moreover, B) might be a lot harder to get to work, as it involves
 reconstructing the picture display order from the HEVC elementary stream,
 to compute a PTS and a DTS. In A), the PTS and DTS are provided by the

 (Of course, I might be wrong about this, and both problematic behaviors
 might have the same root issue.)
