Possibility to extract anc data?

[acastr]

I'm trying to extract a specific data track inside an mxf. I know the data is there if i use mxf2raw; (example output below)

I know how to decode the raw hex data inside the vanc but I haven't been able to extract the specific track to text (or any other format)

I'm trying to build a cli app that can extract all SCTE data from a recorded mxf file, but I'm failing already at being able to extract the data track.

Could you please point me into the right direction? (although it might not seem that way, I already tried the various exe's supplied but it seems I'm not finding the correct option flags)

Or any other approach if I'm not approaching this in the proper way.
Kind regards,
Anthony

I can't try it myself atm, but the -p option can be used to extract the raw binary data for all tracks. It'll probably include the ST436 header for the data tracks which is shown in the mxf2raw text dump. The --disable-* options can be used to not extract from tracks you don't want.
