### Unknown function info

- [_sceVideoRecordingQueryParam_nid_postfix](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - declared with `void(void* param)` signature following [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Video/VideoRecording.cs#L67-L69); unimplemented and throws `NotImplemented_nid_no_patch`
- [sceVideoRecordingCloseByHandle, sceVideoRecordingGetInfoByHandle](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - inferred handle-based recording control signatures taking an integer recording handle; unimplemented and throw `NotImplemented_nid_no_patch`
- [sceVideoRecordingCopyBGRAtoNV12](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - inferred pixel buffer conversion signature `(void* dst, const void* src, uint32_t width, uint32_t height)`; unimplemented and throws `NotImplemented_nid_no_patch`
- [sceVideoRecordingGetSupportInfo, sceVideoRecordingGetVideoOutMode](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - query signatures taking an output pointer; exact structure layouts and return values are unverified and throw `NotImplemented_nid_no_patch`
- [sceVideoRecordingInit, sceVideoRecordingTerm](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - parameterless initialization and termination stubs; unimplemented and throw `NotImplemented_nid_no_patch`
- [sceVideoRecordingInitialize](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - initialization stub taking an optional parameter structure pointer; unverified and throws `NotImplemented_nid_no_patch`
- [sceVideoRecordingOpen2](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - extended recording open signature; parameters inferred from `sceVideoRecordingOpen` and [fpPS4](https://github.com/red-prig/fpPS4); unimplemented and throws `NotImplemented_nid_no_patch`
- [sceVideoRecordingQueryHddSize2, sceVideoRecordingQueryMemSize2](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - memory and disk size query signatures taking parameter pointer; unverified and throw `NotImplemented_nid_no_patch`
- [sceVideoRecordingQueryMemSize](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - signature `int(const SceVideoRecordingParam*)` from [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Video/VideoRecording.cs#L75-L77), which says only that it reports the heap bytes needed for the settings in the parameter; how the size follows from `ringSec` and the format is not documented. [`MaxMemSize` (4096)](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Video/VideoRecording.cs#L64-L65) is the largest heap the recorder needs, an upper bound and not the size for given settings, so returning it would be invented. Throws `NotImplemented_nid_no_patch`
- [sceVideoRecordingOpen, sceVideoRecordingStart, sceVideoRecordingStop, sceVideoRecordingClose](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - signatures from [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Video/VideoRecording.cs#L79-L101). The recorder is not modelled, so these throw `NotImplemented_nid_no_patch` instead of pretending to record. SharpProspero documents no error code for an unavailable recorder; [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/15abf68c9b52c4b04d094f2837719fdb871021f3/src/core/libraries/video_recording/video_recording_error.h#L9-L18) lists codes such as `0x80A80008` (UNSUPPORTED), but nothing shows the console returns one here
- [sceVideoRecordingRestModeProcessGetStatus, sceVideoRecordingRestModeProcessStart](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - rest mode recording interfaces; unverified and throw `NotImplemented_nid_no_patch`
- [sceVideoRecordingSendCommand](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) - command dispatch signature taking integer command ID and parameter pointer; unverified and throws `NotImplemented_nid_no_patch`

### Functional

- [sceVideoRecordingGetStatus](../../../core/libs/prx/libSceVideoRecordingP/Export.cpp) (libSceVideoRecordingP) always returns 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). It is true here because `sceVideoRecordingOpen` throws, so no recorder is ever open. Unverified: whether the console returns 0 or an error before `sceVideoRecordingInit`/`sceVideoRecordingInitialize`, which throw, and when it reports `Running` (1) or `Paused` (2)
