@quietvoid The colors of a P5 profile mkv file look like the mp4 files looked some minutes ago (mainly purple/green). How do the colors look for you?

They look green and purple for me too, as Dolby Vision isn't triggered.
If I force my device into Dolby Vision mode, it looks the same as without.

If you don't see the same colors in mp4 and mkv, then it would mean the video isn't being processed and displayed properly.
You can always compare the color in ExoPlayer if you're uncertain.

What do you mean with "it looks the same as without"?

I played the P5 mkv file with both ExoPlayer and fandagos' latest Jenkins build and they look exactly the same on my Philips 48OLED935. DV is automatically triggered with both as well.

Are you saying you cannot get that file to play with the proper colors using any of the test builds?
