Implement sceVdecCoreQueryInstanceSize, sceVdecCoreQueryFrameBufferInfo, sceVdecCoreQueryComputeResourceInfo, sceVdecCoreCreateDecoder, sceVdecCoreDeleteDecoder and sceVdecCoreMapMemoryBlock as shadPS4's vdeccore.cpp does at 0614ce324b: its argument and codec-type checks, its 1920x1080 and 16-frame defaults, DPB counts from -1 to 16, its instance, compute and frame-buffer sizes, and frame-buffer slots cut from mapped blocks. CreateDecoder opens an FFmpeg H.264 or HEVC context with the FFmpeg the tree already links for libSceVideodec2 but starts no decode thread. The library gets its own CMakeLists.txt and a guest_vdec_core test.

Unknown function info
- sceVdecCoreAnalyzeStream, sceVdecCoreFinalizeComputeResource, sceVdecCoreFlushDecodeOutput, sceVdecCoreGetDecodeOutput, sceVdecCoreInitializeComputeResource, sceVdecCoreResetDecoder, sceVdecCoreSetDecodeInput, sceVdecCoreSetDecodeOutputSw, sceVdecCoreSyncDecode, sceVdecCoreSyncDecodeOutputSw, sceVdecCoreSyncDecodeWptr, sceVdecCoreTrySyncDecode, sceVdecCoreTrySyncDecodeOutputSw and sceVdecCoreTrySyncDecodeWptr (libSceVdecCore) - names and NIDs are present in the PS5 3.20 export inventory, but no credible prototypes were found. The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified
Functional
- sceVdecCoreQueryInstanceSize, sceVdecCoreQueryFrameBufferInfo, sceVdecCoreQueryComputeResourceInfo, sceVdecCoreCreateDecoder, sceVdecCoreDeleteDecoder and sceVdecCoreMapMemoryBlock (libSceVdecCore) - console behaviour is unmeasured. The signatures, error codes, 1920x1080 and 16-frame defaults and slot cutting follow shadPS4's
vdeccore.cpp, and the sizes are shadPS4's constants, not console values: instance 0x40000, compute 0x10000, and a frame buffer of NV12 plus 0x1000 rounded to 64 KiB. CreateDecoder opens an FFmpeg H.264 or HEVC context but starts no decode thread; the memory info and compute queue are ignored, and a handle CreateDecoder did not return, or a codec that is unavailable or fails to open, throws
