Takes a type-0x45 input buffer, a s32 '''width''', and a s32 '''height''', no output.
'''width''' must be 1280, '''height''' must be 720, and the buffer size must be at least 0x384000. After this validation, this just copies the input buffer to state with size 0x384000 and returns 0.

This is "nn::grcsrv::IRemoteVideoTransfer".
This was added with [[6.0.0]].
The max sessions for this service is 4, and it uses 2 IPC handler threads.

== Cmd1 ==
== Initialize ==
Begins video stream. Can only be called once.
No input/output.
Begins video stream. This must not be used more than once, even from a different service session: otherwise the sysmodule will assert.
== Transfer ==
Takes an u32 '''stream''' (0: video, 1: audio) and a type-0x6 output buffer, returns 2 u32s '''num_frames''' and '''data_size''' and an u64 '''start_timestamp'''.
Retrieves stream data from the continuous recorder in use. Video stream writes H.264 NAL units to the output buffer (try <code>ffplay -f h264</code>). Audio stream is PCM16, 2 channels, and sample-rate = 48000Hz. Official code uses buffer size 0x32000 for video, 0x1000 for audio, and multiple threads to read out both streams at the same time.
This will block until data is available. This will hang if there is no game title running which has video capture enabled.

Takes an input u64 '''LayerHandle''', no output.
This is the first cmd used by official sw when finishing recording. Then it waits on the Event originally loaded from [[#GetOffscreenLayerRecordingFinishReadyEvent]]. Then CompleteOffscreenRecordingFinishEx* is used, depending on the sdk-nso version. On any errors, [[#AbortOffscreenRecording]] is used.

Seems to be unused by official user processes, [[#CompleteOffscreenRecordingFinishEx0]] is used instead.
Seems to be unused by official user processes, [[#CompleteOffscreenRecordingFinishEx0]] is used instead.
The input buffer contains the optional ApplicationData for the JPEG thumbnail, size must be <=0x400.
The recorded video will not be accessible via the Album-applet since it's stored separately from other Album data.
== CompleteOffscreenRecordingFinishEx0 ==
== CompleteOffscreenRecordingFinishEx0 ==
Takes two input u32s '''width'''/'''height''', an input u64 '''LayerHandle''' and 2 type-0x5 input buffers, no output.
Takes two input s32s '''width'''/'''height''', an input u64 '''LayerHandle''' and 2 type-0x5 input buffers, no output.
The input buffers are optional, addr=NULL and size=0 can be used for these.
The input buffers are optional, addr=NULL and size=0 can be used for these. The first buffer is for [[#CompleteOffscreenRecordingFinish|ApplicationData]], the second buffer buffer contains the RGBA8 image thumbnail.
'''width'''/'''height''' must be 1280x720, these fields are unused afterwards.

Takes two input u32s '''width'''/'''height''', an input u64 '''LayerHandle''' and two type-0x5 input buffers, returns a 0x20-byte output struct.
Takes two input s32s '''width'''/'''height''', an input u64 '''LayerHandle''' and two type-0x5 input buffers, returns an output [[Capture_services|ApplicationAlbumEntry]].
Same as [[#CompleteOffscreenRecordingFinishEx0]] except the output struct is returned in the cmdreply. Official sw copies the output struct into a "nn::album::AlbumFileEntry".
== GetOffscreenLayerError ==
Takes an input u64 '''LayerHandle''', no output.
== EncodeOffscreenLayerAudioSample ==
== EncodeOffscreenLayerAudioSample ==
Takes an input u64 '''LayerHandle''' and a type-0x5 input buffer, returns an output u64.
Takes an input u64 '''LayerHandle''' and a type-0x5 input buffer, returns an output u64 '''out_size'''.
Official sw enters a loop for handling the user-specified buffer:
* Waits on the Event originally loaded from [[#GetOffscreenLayerAudioEncodeReadyEvent]].
* Uses the cmd with the current buffer_addr+pos and the remaining_size.
* Updates the current pos and remaining_size with the '''out_size'''.
* Repeats the loop until the remaining_size is 0.
