H264 long gop is not supported yet? about bmx

[philipnbbc]

bmx has support for lgop but I'm sure it has limitations. I can't tell from those messages what the issue is but suspect it's how the content has been indexed. Are you able to provide the input file so I could see what the issue could be? Alternatively, provide the output of MXFDump --no-limit-entries <mxf file> for the input and bmxtranswrap output?

Dear,
You can get the input file at below URL:
https://drive.google.com/file/d/1dN1dyxHv-e0c65ThgLljO2hHvluB9yOM/view?usp=drive_link
And I attach the mxfdump output file.
mxfdump_output.txt

Below is bmxtranswrap output of command bmxtranswrap -o output.mxf --clip test Clip0003.mxf:

Warning (libMXF): Failed to de-reference strong reference array element (item key = 06 0e 2b 34 01 01 01 09 06 01 01 04 06 10 00 00)

Thank you.

Thanks for the file and info. I've had a look and found that the H.264 video uses separate field encoding and that's not supported in bmx. I'll see when I have time to figure out how far off support for separate fields was as it was years ago since I worked on this.
