hi edinsac your box is an allwinner, so my build is no good. try asking in the appropriate section of this forum
keesijp60 unfortunately not, I need a driver (possibly updated to the latest versions of the Linux kernel). After doing some research I found one, but I don't know if it's usable.
BakaKilluaTo. get an SD card and write my image on it as indicated in the first post. I've never seen the box but it seems compatible (consider that the specifications I see in the link could be fake, I have never seen rk322x boxes with more than 2GB of RAM and 16GB of storage). I also ask you to send a link to the original version of the firmware so that I can study it better.
miclass The SOC supports hardware decoding for MPEG4, but I believe the software basis to implement it is missing in modern Linux kernels. I don't know the reason why no one has ever done it, but I imagine it's related to the obsolescence of the codec. The box restarts probably because it reaches high temperatures given that the decoding takes place via software. However, MPEG4 is quite easy to decode so I don't expect the CPU to be at 100% fixed. can you check this, please? maybe you can also tell me the resolution of the TV and that of the video you are playing?
