== GetAppletProgramIdTable ==
Takes a type-70 buffer and returns a bool. If the buffer is sufficient it writes two application ID's to the buffer (0x100000000001000 and 0x100000000001fff) and returns true. This is used by photoViewer to group all screenshots of applets.
== GetAlbumFileName ==
Takes an input [[#AlbumFileId]] and a type-0x6 output buffer. Writes the filename of the corresponding file to the buffer.
== LoadAlbumScreenShotImageEx1 ==
Takes a total of 0x38-bytes of input, two type-0x5 input buffers, and returns 0x20-bytes of output. [4.0.0+] No longer returns output, and now takes the following buffers instead: type-0x16, type-0x46, and type-0x6.
== OpenAccessorSession ==
Takes a total of 8-bytes of input, a PID, and returns an [[#IAlbumAccessorSession]].
== IAlbumAccessorSession ==
This is "nn::capsrv::sf::IAlbumAccessorSession".
This was added with [4.0.0+].

== SetShimLibraryVersion ==
== SetShimLibraryVersion ==
Takes a total of 0x10-bytes of input and a PID, no output.
Takes an input u64 [[#ShimLibraryVersion]], an u64 [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]], and a PID, no output.
== GetAlbumFileList0AafeAruidDeprecated ==
Takes a type-0x6 output buffer containing an array of [[#ApplicationAlbumFileEntry]], a PID, an u8 [[#ContentType]], two s64s, and an u64 [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]]. Returns an output u64 for total output entries (which is copied to a s32 by official sw).
The two s64s are the start/end PosixTime.
== DeleteAlbumFileByAruid ==
Takes a PID, an input u8 [[#ContentType]], an [[#ApplicationAlbumFileEntry]], an [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]], and no output.
The [[#ContentType]] must match 3.
== GetAlbumFileSizeByAruid ==
Takes a PID, an input [[#ApplicationAlbumFileEntry]], an [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]], and returns an output u64.
This gets the filesize for the entire specified Album file.
== DeleteAlbumFileByAruidForDebug ==
Takes a PID, an [[#ApplicationAlbumFileEntry]], an [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]], and no output.
The cached value loaded from [[Settings_services#GetDebugModeFlag]] must be 1, otherwise an error is returned.

Takes a PID, a type-0x16 output buffer containing a [[#LoadAlbumScreenShotImageOutputForApplication]], a type-0x46 output buffer, a type-0x6 output buffer, an [[#ApplicationAlbumFileEntry]], a [[#ScreenShotDecodeOption]], and no output.
The type-0x46 buffer contains the RGBA8 image data. The type-0x6 buffer is a work buffer used for reading the entire AlbumFile, the buffer size must be at least the AlbumFile filesize (cleared before the cmd returns).
== LoadAlbumScreenShotThumbnailImageByAruid ==
Takes a PID, a type-0x16 output buffer containing a [[#LoadAlbumScreenShotImageOutputForApplication]], a type-0x46 output buffer, a type-0x6 output buffer, an [[#ApplicationAlbumFileEntry]], a [[#ScreenShotDecodeOption]], and no output.
The type-0x46 buffer contains the RGBA8 image data. The type-0x6 buffer is a work buffer used for reading the entire AlbumFile, the buffer size must be at least the AlbumFile filesize (cleared before the cmd returns).

Takes a type-0x6 output buffer containing an array of [[#ApplicationAlbumFileEntry]], a PID, an u8 [[#ContentType]], two [[#AlbumFileDateTime]], and an u64 [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]]. Returns an output u64 for total output entries (which is copied to a s32 by official sw).
The first [[#AlbumFileDateTime]] is the start_DateTime, the second [[#AlbumFileDateTime]] is the end_DateTime. In the IPC rawdata, these use 2-byte alignment.
== GetAlbumFileList2AafeUidAruidDeprecated ==
Takes a type-0x6 output buffer containing an array of [[#ApplicationAlbumFileEntry]], a PID, an u8 [[#ContentType]], two [[#AlbumFileDateTime]], an u128 userID, and an u64 [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]]. Returns an output u64 for total output entries (which is copied to a s32 by official sw).
The first [[#AlbumFileDateTime]] is the start_DateTime, the second [[#AlbumFileDateTime]] is the end_DateTime. In the IPC rawdata, these use 2-byte alignment.

=== OpenAlbumMovieReadStream ===
Takes a PID, an input [[#ApplicationAlbumFileEntry]], an u64 [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]], and returns an output u64 [[#AlbumMovieReadStreamHandle]].
Up to 4 streams can be open at the same time. Multiple streams can be open at the same time for the same [[#ApplicationAlbumFileEntry]].
=== CloseAlbumMovieReadStream ===
Takes an input u64 [[#AlbumMovieReadStreamHandle]], no output.
=== GetAlbumMovieReadStreamMovieDataSize ===
Takes an input u64 [[#AlbumMovieReadStreamHandle]], returns an output u64.
This gets the size of the actual MP4, without the JPEG at the end.
=== ReadMovieDataFromAlbumMovieReadStream ===
Takes a type-0x6 output buffer, an input u64 [[#AlbumMovieReadStreamHandle]], an input s64 offset, and returns an output u64 actual_size.
offset(+size) must not be negative. offset and size must be aligned to 0x40000-bytes. When offset(+size) goes beyond the size from [[#GetAlbumMovieReadStreamMovieDataSize]], the regions of the buffer which goes beyond that are cleared to 0, and actual_size is still set to the input size.
=== GetAlbumMovieReadStreamBrokenReason ===
Takes an input u64 [[#AlbumMovieReadStreamHandle]], no output.
Unused by official sw.
= ShimLibraryVersion =
This is a version field. Official sw uses func <code>nn::capsrv::GetShimLibraryVersion()</code> to load this from a global var, which is then used with various commands (the input for those cmds must match value 1).
[7.0.0-9.0.0] This is value 1.
Controls which struct version to use for [[#ApplicationAlbumEntry]] / [[#AlbumFileEntry]]. However, the struct size for the newer version is used regardless on [7.0.0+] for the actual cmds.

This is "nn::capsrv::ApplicationAlbumEntry". This is a 0x20-byte struct. On older versions where [[#ShimLibraryVersion]] is 0, this was a plain AES256 with a random key generated at application launch.
With the output from [[Applet_Manager_services#caps:su|caps:su]] sdk-nso only uses this for the [[Internet_Browser|Share-applet]] (when the output is used at all), with everything else it's used as an [[#AlbumFileEntry]]. In those cases with the <code>nn::album</code> wrapper funcs, it's "converted" by just copying the struct (arrays are "converted" by just returning a ptr to the input array).

This is "nn::capsrv::ApplicationAlbumFileEntry". This is a 0x30-byte struct.
On newer versions where official sw uses [[#ApplicationAlbumEntry]], [[#ApplicationAlbumEntry]] is converted to ApplicationAlbumFileEntry when using cmds which need it with:
* First 0x20-bytes are the same.
* u64 ApplicationAlbumFileEntry+0x20 = [[#ApplicationAlbumEntry]]+0x10.
* Last 8-bytes = 0.

[[4.0.0]] includes video playback etc support in Album via mp4. These include a JPEG thumbnail, which is used for video "validation". The EXIF is also much larger: the MakerNote is 0x498-bytes, with encrypted data starting at offset +0x8. This encryption uses AES-CTR with hardcoded key/ctr. MAC calculation works the same way as the [[3.0.0]]+ JPEG MAC calculation, except with a different movie_kek_source/movie_key_source.

Each 0x40000-byte chunk in the Movie data stream is validated with a SHA256 hash table, where hash_index=offset>>18. Whether an error is thrown on mismatch is controlled by [[System_Settings|system-setting]] "capsrv!enable_album_movie_filehash_verification".
Note: the Album process itself uses libstagefright for video playback.
