VMS P 9b - Aiptek video OK

I've just loaded VMS9.0b on Vista 64 bit, which is working well. First test project was 1280 x 720p @60fps from the Aiptek A-HD camera. Yes, that's the one that the VMS9.0b Release Note specifically identifies as not supported,

Initial results were that the video loaded normally, but the audio track was not being loaded at all. After a bit of checking, it became clear that VMS was mis-reading the header, which caused the problem. Aiptek saves H.264 encoded video with AAC encoded audio. VMS was reading the file as having MPEG4 audio!

The simple solution is to change the video file extension from .MOV to .mp4 and then open VMS and drag the video into your project. In my case that works perfectly. YMMV, of course, but it appears to be a very simple solution for Aiptek users.

AAC is mpeg4 audio. So this part was correct. The problem seems to be that the main concept decoder was failing to read the file, while when changing to .mov, the quicktime decoder took over, in which case it did not have the bug. But it might have other ones...
