The problem is that I have to watch some MIT OCW video lectures on my mobile device and I'm using MX player to watch these videos. The catch is that I want to watch 50 minute lecture in 25-30 minute but I seem to find no way out to do this on android. I know I can play those videos on VLC media player on a laptop at 2x speed but the problem is that I don't have a laptop.
Suggest me what can I do. How can I watch them at 2x speed?
P.S. I use an android device version 4.1 jellybean. Also I'm not streaming the videos I have already downloaded the videos and now want to watch them offline.
