We have a huge problem, we bought devices with Allwinner H6 processors. They have been really good in video playback with looping without black frame. They had Android 7 installed. Now they come with Android 9 and video playback in Xibo is 3 times faster and then it holds on last frame until normal speed video time ends. Then it plays next video, 3 times faster. All the devices same, we tested 5 of them and we are quite disappointed. If we cannot solve it we lost quite a lots of money.
How is it possible?
