Album uses [[Applet_Manager_services#CreateGameMovieTrimmer|CreateGameMovieTrimmer]], and retries using the cmd in a loop on error 0x8D4 with svcSleepThread(100000000) being used first. Then all 4 of these commands are used in that same func: [[#SetThumbnailRgba]] if the input buffer is set, [[#GetNotTrimmingEvent]], [[#BeginTrim]], waits on the event, then [[#EndTrim]] and cleanup.
 
=== BeginTrim ===
Takes an input s32 '''start''', a s32 '''end''', and a [[#GameMovieId]], no output.
 
The two s32s are the start/end timestamps in 0.5s units.
 
=== EndTrim ===
No input, returns an output [[#GameMovieId]].
 
This just loads the [[#GameMovieId]] from state, when available.
 
=== GetNotTrimmingEvent ===
No input, returns an output Event handle with autoclear=false.
 
=== SetThumbnailRgba ===
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.

= IUnknown =Cmd1 ==Begins video stream. This must not be used more than once, even from a different service session: otherwise the sysmodule will assert. == Cmd2 ==Retrieves stream data, from the video recording being done of the currently running game title. Takes u32 "stream" (0: video, 1: audio), returns u32 (num_frames?), u32 data_size, u64 (start_timestamp?). 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. = IOffscreenRecorder =This is "nn::grcsrv::IOffscreenRecorder". This was added with [5.0.0+].
