After some days mucking about with the FFMPEG decoding and everything around it, it looks like he issue was solved by replacing the default media player element.
It is working like a charm. Very happy with it and I can’t wait to share the new version (it will be V2.2.x).
Of course, progress isn’t free. This media player doesn’t like having the playing media change… it works on ARM but in x86 it plays audio only.
I have made it work but not in a way I am happy with. Once I Get that figured out the new player, with no playback speed or chipmunk audio issues, will be released to store.
