# libSceVideoRecordingP technical debt

### Unknown function info

- [sceVideoRecordingGetInfo, sceVideoRecordingSetInfo](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) support native validation and errors before a recording context exists. Opening a recorder and initialization remain unimplemented; live recording queries, control and volume changes are unavailable.

- [13.60 remaining inventory exports](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) - `sceVideoRecordingGetCopyrightImageMemory` (`PAKwtO6i9d8`), `sceVideoRecordingCloseWithTruncationByHandle` (`oryBI-2iyxw`) have unknown signatures and behavior. Parameterless `int` declarations are import-resolution placeholders, not verified ABI prototypes; every call throws through `NotImplemented_nid_no_patch`. These defined name/NID bindings come from the [13.60 export inventory](https://github.com/xdCloudy/PS5-13.60-Function-Stub-Library/blob/bfec40deb4c47a17d7603ee2bc79aa6862c0c56b/data/firmware-13.60/libscevideorecordingp-2f2509cb1b.jsonl).

- [_sceVideoRecordingQueryParam_nid_postfix](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp): the supplied module reads a 64-bit size and writes a 32-bit mode at offset 12 for sizes at least 16, plus a 32-bit option at offset 28 for sizes at least 64. Mode/option meanings remain unresolved; the protected implementation is unchanged.
- [sceVideoRecordingCloseByHandle, sceVideoRecordingGetInfoByHandle](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) - native handles are context pointers. Recording state and per-handle queries remain unimplemented.
- [sceVideoRecordingCopyBGRAtoNV12](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) - the destination, source, 32-bit width and height arguments are confirmed. Pixel conversion remains unimplemented.
- [sceVideoRecordingGetSupportInfo, sceVideoRecordingGetVideoOutMode](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) - GetSupportInfo writes an 18-byte payload whose fields remain unresolved. GetVideoOutMode takes a four-byte output confirmed by the native recording assembly and Avcap2 IPC descriptor; the mode values remain unresolved. Both exports remain unimplemented.
- [sceVideoRecordingInitialize](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp): the native initializer consumes no caller arguments; the former optional parameter is not read by the Avcap2 initializer or recording setup. Its unused parameter slot is retained because the protected body references it.
- [sceVideoRecordingOpen2](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) - the 40-byte parameter variant, four argument registers and 32-bit heap size are recovered. Mode, output mode, option and format semantics remain incomplete. QueryHddSize2 returns a signed 64-bit size or error; recording and sizing exports remain unimplemented.

- [Handle and support queries](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) - native recording handles are context pointers, and GetSupportInfo writes 18 bytes. Support payload field semantics remain incomplete. RestModeProcessStart, RestModeProcessGetStatus and SendCommand consume no caller arguments in the supplied native module; their existing unused parameter slots remain because the protected bodies reference those parameter names.

### Functional

- [sceVideoRecordingGetStatus, sceVideoRecordingStart, sceVideoRecordingStop, sceVideoRecordingClose](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) answer as a PS5 does with no recorder open: GetStatus 0, `None` ("The recorder is not open") in [SharpProspero's `VideoRecordingStatus`](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Video/VideoRecording.cs#L18-L29), also listed in [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/15abf68c9b52c4b04d094f2837719fdb871021f3/src/core/libraries/video_recording/video_recording.h#L32-L36), and 0x80A80006 from the other three, measured on firmware 13.40 inside PPSA01317 without `sceVideoRecordingInit`. It is true here because `sceVideoRecordingOpen` never opens one. Unverified: when GetStatus reports `Running` (1) or `Paused` (2)

- [sceVideoRecordingOpen, sceVideoRecordingQueryMemSize](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) never open a recorder: both throw for a block with a video format, and Open throws for any block it accepts, because neither the heap size nor the recording session is implemented. The checks before that follow a PS5 (firmware 13.40, measured inside PPSA01317): QueryMemSize returns 0x80A80003 for a block shorter than 16 bytes, a duration outside 1 to 3600 seconds, a mode or option above 1 and an unknown format, 0x80A80008 for the option without a format and 0x1000 for neither, and Open refuses null arguments and a negative or too small heap with 0x80A80003. Read and not measured: Open checks the affinity mask, thread priority and output mode after the heap size
