Comment (by cehoyos):
Am I correct that for the Telestream file, no frames are missing?
I don't know what you are trying to do but you cannot generally cut files
with {{{-vcodec copy}}} and for the first file you uploaded, the reference
decoder produces the same output as FFmpeg (meaning any software that
outputs different frames has a bug).
Work-around is to use {{{-flags2 +showall}}} which makes decoding
(possibly) non-compliant.
