Hello list,

I sent this mail to the list earlier today, before I actually subscribed. Didn't 
get an error, but also not sure if it was silently discarded, hence, this second 
attempt.

I am currently running ffmpeg version N-112750-g6d60cc7baf with the following 
library versions:

   libavutil      58. 32.100 / 58. 32.100
   libavcodec     60. 33.100 / 60. 33.100
   libavformat    60. 17.100 / 60. 17.100
   libavdevice    60.  4.100 / 60.  4.100
   libavfilter     9. 13.100 /  9. 13.100
   libswscale      7.  6.100 /  7.  6.100
   libswresample   4. 13.100 /  4. 13.100
   libpostproc    57.  4.100 / 57.  4.100

When decoding an mkv file containing an h264-stream I have received from a third 
party, file I get a bunch of the following errors:

===
[h264 @ 0x5599bde1a0c0] Late SEI is not implemented. Update your FFmpeg version 
to the newest one from Git. If the problem still occurs, it means that your file 
has a feature which has not been implemented.
[h264 @ 0x5599bde1a0c0] If you want to help, upload a sample of this file to 
https://streams.videolan.org/upload/ and contact the ffmpeg-devel mailing list. 
(ffmpeg-devel@ffmpeg.org)
===

Is this interesting to you? Do you want me to upload the sample? It might be of 
dubious nature regarding copyright, depending on local legislation.

regards

Harald
