segmentation fault when creating a QCTools report for a file with 2 Stereo Audio Channels #851

Open iamdamosuzuki opened 2 weeks ago

iamdamosuzuki commented 2 weeks ago

I get an error when attempting to capture a 4 Channel audio file (2x Stereo Channels) with vrecord set to create a QCTools report after capture. Creating the QCTools file after capture works perfectly well if done on a file with a single stereo channel. Here's te error i Get, you can see the segmentation fault near the end.

I did some further testing and found that this is a qcli error. I've made a ticket here: https://github.com/bavc/qctools/issues/842

Let me know if you want me to close this ticket.

thanks for the further testing @iamdamosuzuki! I suppose we might as well leave this open for the time being so people who are trying to use this feature might find it. We'll just have to remember to close once this is resolved upstream.
