📄 Description

Some games check the computeQueue output of sceVideodec2AllocateComputeQueue before performing video decoding. These titles were hanging when they should play videos as a result.

Based on some decompilation and debugging of this library's code, it appears that the returned compute queue pointer is always part of the inputted cpuGpuMemory, so to make affected titles work, I just return the cpuGpuMemory pointer as the compute queue.

This fix brings NEO : The World Ends with You ingame, with no noticeable cutscene issues.

My own testing doesn't reveal any regressions, though I don't have many games using libSceVideodec2.
