MediaPlayer within TextureView not working as intended
15 mars 2016, par RussieeI’ve put in a MediaPlayer within a TextureView, which itself is located inside a ListView.
Yesterday, the MediaPlayer worked as intended with a test .mp4 clip.
Today, the MediaPlayer tries doing some kind of FFmpeg Extractor, for which i’ve been unable to find any kind of information about.This is the stack trace :
