 Replying to [comment:4 Gyan]:
 > Have you tried the dts2pts bsf?


 ffmpeg -i http://slydiman.me/ffmpeg/b-frames.h264 -c:v copy -bsf:v dts2pts
 dts2ptsstrange.mp4

 makes it a little better, but the end is still bad, also, that still does
 not fix the

 [[h264 @ 00000186dc07f8c0] non-existing SPS 0 referenced in buffering
 period
 ]

 and still gives VFR file (mediainfo app):


 {{{
 Frame rate mode             : Variable
