 I have some troubles when trimming without re-encoding a H264 All-Intra
 High 422 file (10bits) from a Canon Camera.

 Here is the command I'm using :

 {{{
 ffmpeg.exe -loglevel trace -ss 6.74 -i
 Canon_Trimming_Error_H264_422_Intra_10bits.MXF -t 1 -c copy -map 0:v -map
 0:a Canon_Trimming_Error_H264_422_Intra_10bits_OUT.MXF
 ffmpeg Master 27/01/2022 - Commit : 3c831847a8-full
 Also reproduced with ffmpeg 5.0
 built on Windows
 }}}

 I want to cut the file from a specific frame, that's why "6.74" is given
 in input. Note that it can work by giving other values for input, like "6"
 or "6.5" for example.

 I got the following error :

 [mxf @ 00000251f34db180] Received non-video packet before header has been
 written
 Error writing trailer of
 Canon_Trimming_Error_H264_422_Intra_10bits_OUT.MXF: Invalid data found
 when processing input

 I tried on a lot of files I have and depending on the input I provide,
 sometimes it works, and other timed not with the same error.

 Here is the file :
