With 0.1.4, I have "pulsing" I-frames when playing MP4 video (i.e. visible jump in picture quality every few seconds)
the same files don't exhibit this problem when played with the Samsung S4 mini video player

Can you post your logs ?

Hardware acceleration on/off?

Video specifications?

hw acceleration was off (default)
when on, all is fine
