Posting this at ps4miner's request: 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:

1. 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.
2. 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).

It looks like official packages somehow got more privileges than fpkgs so some applications are failing to work properly.
Probably a whitelist (which is coming from PSN on activation) or fpkgs lack of some sort of marker. More research is needed.

I wanted only this particular application to work, now my work is done. I hope you enjoy it
