[FFmpeg-user] conversion mp4 -> ts gives error: non-existing SPS 0 referenced in buffering period

[Bernd Pfrommer]

I am trying to concatenate several mp4 files together, but conversion
from mp4 to ts is producing a file with errors, and subsequent
concatenation attempts produce an erroneous output file as well.

Here is what I'm using for conversion:

ffmpeg -v warning -y -i seq2.mp4 -c copy -bsf:v h264_mp4toannexb -f
mpegts seq2.ts

(no error message, seems to work fine)

But the resulting .ts file gives error when I try to play it, or even
just ffprobe it, like so:

ffprobe -v warning -select_streams v -show_streams seq2.ts

[h264 @ 0x3a9e160] non-existing SPS 0 referenced in buffering period
    Last message repeated 1 times
[h264 @ 0x3a9f9a0] non-existing SPS 0 referenced in buffering period
[STREAM]
.... more output here
[/STREAM]

Could somebody please advise?

Thanks!

Bernd
