QVideoProbe and avi format

[kazaak]

I am using a QVideoProbe with QMediaPlayer and QVideoWidget. I am getting videFrameProbed signals for every file format I've tested (flv, mp4, mkv) except for avi. avi files play with the QVideoWidget, however, just no videFrameProbed signals. I've tried setting the source of the probe after loading the media file using setSource() on the probe and it returns true just prior to playing the file. Is there something additional required with avi files? I've tried several different avi files and not a single one works.

I'm using Qt 5.15.2 MSVC2019 32bit with K-lite 16.7.4 Basic.
