GRC (Game Recording) uses libstagefright and the NvMMLite TVMR library for writing recorded video to MP4s.
Error reporting is done using the new /dev/nverpt-ctrl ioctls.

IMovieMaker
This is "nn::grcsrv::IMovieMaker".
CreateVideoProxy
No input, returns an #IHOSBinderDriver.
OpenOffscreenLayer
Takes an input u64 LayerHandle, returns an output u32.
CloseOffscreenLayer
Takes an input u64 LayerHandle, no output.
StartOffscreenRecording
Takes an input u64, no output.
Seems to be unused by official user processes, #StartOffscreenRecordingEx is used instead.
AbortOffscreenRecording
Takes an input u64 LayerHandle, no output.
RequestOffscreenRecordingFinishReady
Takes an input u64 LayerHandle, no output.
StartOffscreenRecordingEx
Takes an input u64 LayerHandle and an #OffscreenRecordingParameter, no output.
CompleteOffscreenRecordingFinish
Takes an input u64 and a type-0x5 input buffer, no output.
Seems to be unused by official user processes, #CompleteOffscreenRecordingFinishEx0 is used instead.
CompleteOffscreenRecordingFinishEx0
Takes an input u64 LayerHandle and 2 type-0x5 input buffers, no output.
EncodeOffscreenLayerAudioSample
Takes an input u64 LayerHandle and a type-0x5 input buffer, returns an output u64.
GetOffscreenLayerError
Takes an input u64 LayerHandle, no output.
GetOffscreenLayerRecordingFinishReadyEvent
Takes an input u64 LayerHandle, returns an output event handle.
GetOffscreenLayerAudioEncodeReadyEvent
Takes an input u64 LayerHandle, returns an output event handle.
OffscreenRecordingParameter
This is a 0x80-byte struct.
