Binaries for Hardware Accelerated Qt 5.6.0-rc1 Multimedia Backend on Raspbian Jessie Lite (POT 5.2.2)

This is a new build including a video probe to monitor frames being rendered. I also included a plugin to access video probe functionalities from QML. You can use it like this:

POT_VideoProbe {
   source: mediaPlayer
   onVideoFrameProbed: console.log("Frame probed!")

where mediaPlayer is an element of type MediaPlayer. Modifying the frame is not probably possible at the moment.
Have fun! Bye ;-)

Fully Optimised Raspbian Jessie Lite with Accelerated Qt Multimedia Backend (Pi2)

This is a follow-up to the image provided in this article. The concept is identical, but in this case this firmware is smaller, it is based on Raspbian Jessie Lite and includes updated software. The firmware was 1.9GB while now is 759MB. This is the current setup (but I encourage to update to the latest possible firmware):
