Comment (by david333):

 I am using the libavcodec API to parse and decode my input, I also use it
 for my encoding. At this time I cannot upgrade the ffmpeg API. However, I
 might be able to use a newer ffmpeg version via the CLI. Is there a way to
 add SEI messages (timecodes or any type of user data) to each frame via
 the command line? I looked online but I have yet to find such a command
 that will do this.

 You mentioned above that the error is indicating there were only four
 packets with actual frames. When I look at the trace_header.txt file
 (attached to this ticket) I can see there are 6 packets, 6 slice segment
 headers and only 4 User data SEIs. Please let me know if you would like me
 to run any further commands on my video file in hopes of gathering more
 information.
