Comment (by slydiman):

 So, the message like
 {{{
 [mp4 @ 000001933f6ed800] Timestamps are unset in a packet for stream 0.
     This is deprecated and will stop working in the future.
     Fix your code to set the timestamps properly
 [mp4 @ 000001933f6ed800] pts has no value
 }}}
 during copying is the sign of the problem.
 Probably it must be fixed somewhere in
 https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/demux.c

 I don't see any problem around the warning {{{non-existing SPS 0
 referenced in buffering period}}}. MP4 is playable anyway because SPS and
 PPS will be inside avcC atom which is read before mdat.
