Fluctuate framerate during playback #2

I just found out that during playback, the frame rate would fluctuate badly with videos with a lot of movement. A 10 mins source file (just to give an example) will result in a 14'20'' file. This happens to both yours and the original c code.

To make sure that the source file is not the problem, I used the baked in mp4 video converter that comes with the default mobile app and it gives a perfect video playback.

Best.

Unfortunately the source format of these IP cameras is proprietary and we can only guess (or reverse engineer) what the Windows application does. I once asked the manufacturer of my camera about the format but he didn't want to provide any information.
