Import MXF OP1a to Interplay using AMT SDK

Hi,

I want to import MXF OP1a AVCIntra100 to interplay using AMT SDK. I convert the file to Atom files using bmxtranswrap open source tool. I use following command:

bmxtranswrap --rt 1.0 -t avid --avid-gf --avid-gf-dur 90000 --force-no-avci-head --tape "AvidTDIR" -o "C:\Avid\AvidTDIR" "C:\Avid\Source\AvidTDIR.mxf"

If I read the files while capturing is not finished using ReadAmtTrackSample after some frames I get a small sample size (12) and the WriteAmtTrackSample failes with AMT_UNKNOWN_EXCEPTION_RAISED (72).

If I use the bmxtranswrap without duration (--avid-gf-dur 90000) I get an error when opening the MXF video file.

Do you have any idea what could be wrong?

Thanks
