J2K/MXF support in QCTools?

[belak1]

I'm having issues analyzing interlaced JPEG2000 files wrapped in MXF with QCTools.

QCTools v1.2.1
macOS Monterey 12.6

After generating an MKV report with qcli, the QCTools interface only shows graphs for the audio tracks, not the video. The preview frames also appear only as half height (one field).

I can load filters, but only slowly and I can't actually play the video file to preview it with these filters on.

This appears to be related to #141 so I was wondering whether there had been any updates since then. I know QCTools uses ffmpeg, and I've separately had issues using ffmpeg processing on any of these J2K/MXF files, which results only in half-height files. This file is 720x486, while the ffprobe output (below) shows 720x243.
