This is a patched version of official PS4 Media Player 3.50 (VR supported) so it can play music and video on non PSN-activated console.
Will work only on 5.05/5.07 FW because it includes a kexec part with hardcoded offsets (sorry <5.05 guys, my bad).
Running on other than supported FW will make console to reboot.
Also do not forget to turn On MPEG-2 switch at "Debug Setting -> License Activation". Player is checking for it.
It's not the best variant of fixing this app, but it works for now (as a temporary solution).
Basically patch does two things:
- It escalates privileges for the mplayer's process, so it can freely access the stuff it wants.
*sonyCred = 0xffffffffffffffff; // sceSblACMgrIsSystemUcred
*sceProcType = 0x3801000000000013; // sceSblACMgrGetDeviceAccessType
I'm not sure if both patches are necessary. Probably second one is enough, too lazy to check.
- It patches SceMusicCoreServer process in memory.
Function at SceMusicCoreServer+0x3640 will now always <return 0>.
5.07 FW is unchecked but it almost certainly working (at least video should).
