AudioThumbnail is coming across as being unusable with mp3’s via QTAudioReader. High level drawing seems to be fine, but as soon as it drops down to a lower level the app hangs as it loops through AudioThumbnail::getLevels. I’ve noticed that the reader is continually reset to 0 but I haven’t studied the code well enough to understand the significance of that. What I can say is that the other readers don’t seem to do this. At one point when trying to draw a stereo mp3 it managed to suck up all the ram in the machine to the point where my app was at 2.19 GB’s of RAM usage. Normally it runs at about 12 MB’s.
