 The NULL messages are coming from libavcodec/hevc_parser.c

 The hevc error messages are coming from libavcodec/hevcdec.c

 {{{

 Trying to decode (i.e. without `-c copy`) results in more errors repeated
 continuously:

 {{{

 [hevc @ 0x7fb3a383be00] Error parsing NAL unit #7.
 [NULL @ 0x7fb3a481ee00] PPS id out of range: 1
 Error while decoding stream #0:0: Invalid data found when processing input
 }}}

 Same behavior with ffmpeg master
