* swkbd: Fix a bug where clicking Cancel hangs the game
The text is validated in `Finalize`. If the validation fails, an error is returned and the applet is not actually finalized. This can result in hangs.
This is usually not a problem as the frontend is expected to validate the text passed to `Finalize`. However, when the user clicked on `Cancel`, the text is ignored and the frontend won't do any validation. Therefore, we should skip the validation here as well.
Also fixed a potential data race. All these functions should now be called on the same thread
* Address review comments
Renamed the fields
Remove close button
* vm_manager: Handle multiple areas in ChangeMemoryState
It is possible that a few areas have the same permisson and state, but with different backing pointers. Currently, this function assumes that only one continous area is found, but this is not always the case.
* service/ldr_ro: Handle multiple areas in VerifyBufferState
It is possible that the buffer passed from the game is made up of multiple areas with the same permisson and state but different backing pointers. Change the check to allow that.
When dumping was stopped, the game will be paused and then resumed. However when the game was already paused this will result in the game being unexpectedly resumed, which isn't what we want.
The most important one being adding a mutex to protect the format_context. Apparently it wasn't thread safe (as one'd expect) but I didn't think about that.
Should fix some of the strange issues happening with MP4 muxers, etc.
The file's size is stored in FileSessionSlot and retrieved when the game calls GetSize. However, it is not updated when the file is written to, which can possibly change the file size. Therefore, this can cause GetSize to return incorrect results.
According to HW tests, this vsync event is signaled for activated cameras at about the same frequency as the frame rate. The last 5 vsync timings are recorded (in microseconds) and can be retrieved with the service function.
Also, corrected the default frame_rate to 15, according to HW test.
This should fix the missing camera images in certain games.
You can now directly place ExeFS overrides/patches inside the mod folder (instead of the exefs subfolder). This allows us to have drop-in compatibility with Luma3DS mods.
This is the main dialog of video dumping. This dialog allows the user to set output format, output path, video/audio encoder and video/audio bitrate.
When a format is selected, the list of video and audio encoders are updated. Only encoders of codecs that can be contained in the format is shown.
This dialog allows changing the value and unsetting one option. There are three possible variants of this dialog:
1. The LineEdit layout. This is used for normal options like string and duration, and just features a textbox for the user to type in whatever they want to set.
2. The ComboBox layout. This is used when there are named constants for an option, or when the option accepts an enum value like sample_format or pixel_format. A description will be displayed for the currently selected named constant. The user can also select 'custom' and type in their own value.
3. The CheckBox-es layout. This is used for flags options. A checkbox will be displayed for each named constant and the user can tick the flags they want to set.
These two functions allow the frontend to get a list of encoders/formats and their specific options.
Retrieving the options is harder than it sounds due to FFmpeg's strange AVClass and AVOption system. For example, for integer and flags options, 'named constants' can be set. They are of type `AV_OPT_TYPE_CONST` and are categoried according to the `unit` field. An option can recognize all constants of the same `unit`.
Previously, we just used the native sample rate for encoding. However, some encoders like libmp3lame doesn't support it. Therefore, we now use a supported sample rate (preferring the native one if possible).
FFmpeg requires audio data to be sent in a sequence of frames, each containing the same specific number of samples. Previously, we buffered input samples in FFmpegBackend. However, as the source and destination sample rates can now be different, we should buffer resampled data instead. swresample have an internal input buffer, so we now just forward all data to it and 'gradually' receive resampled data, at most one frame_size at a time. When there is not enough resampled data to form a frame, we will record the current offset and request for less data on the next call.
Additionally, this commit also fixes a flaw. When an encoder supports variable frame sizes, its frame size is reported to be 0, which breaks our buffering system. Now we treat variable frame size encoders as having a frame size of 160 (the size of a HLE audio frame).
We previously assumed that the first preferred sample format is planar, but that may not be true for all codecs. Instead we should find a supported sample format that is planar.
While YUV420P is widely used, not all encoders accept it (e.g. Intel QSV only accepts NV12). We should use the codec's preferred pixel format instead as we need to rescale the frame anyway.
This uses the mailbox model to move pixel downloading to its own thread, eliminating Nvidia's warnings and (possibly) making use of GPU copy engine.
To achieve this, we created a new mailbox type that is different from the presentation mailbox in that it never discards a rendered frame.
Also, I tweaked the projection matrix thing so that it can just draw the frame upside down instead of having the CPU flip it.
10 slots are offered along with 'Save to Oldest Slot' and 'Load from Newest Slot'.
The savestate format is similar to the movie file format. It is called CST (Citra SavesTate), and is basically a 0x100 byte header (consisting of magic, revision, creation time and title ID) followed by Zstd compressed raw savestate data.
The savestate files are saved to the `states` folder in Citra's user folder. The files are named like `<Title ID>.<Slot ID>.cst`.
This holds the archives which include the SelfNCCH archive which holds the RomFS files. If we don't reset it the LayeredFS class can't get destructed and mods files won't be released.
The original path (file_name.exefsdir) is still supported, but alternatively users can choose to put exefs patches in the same place as LayeredFS files (`load/mods/<Title ID>/exefs`).
Only enabled for NCCHs that do not have an override romfs.
LayeredFS files should be put in the `load` directory in User Directory. The directory structure is similar to yuzu's but currently does not allow named mods yet. Replacement files should be put in `load/mods/<Title ID>/romfs` while patches/stubs should be put in `load/mods/<Title ID>/romfs_ext`.
This implementation is different from Luma3DS's which directly hooks the SDK functions. Instead, we read the RomFS's metadata and figure out the directory and file structure. Then, relocations (i.e. replacements/deletions/patches) are applied. Afterwards, we rebuild the metadata, and assign 'fake' data offsets to the files. When we want to read file data from this rebuilt RomFS, we use binary search to find the last data offset smaller or equal to the given offset and read from that file (either from the original RomFS, or from replacement files, or from buffered data with patches applied) and any later files when length is not enough.
The code that rebuilds the metadata is pretty complex and uses quite a few variables to keep track of necessary information like metadata offsets. According to my tests, it is able to build RomFS-es identical to the original (but without trailing garbage data) when no relocations are applied.
The DIGIT filter was incorrectly implemented as preventing all digits. It actually limits the maximum digit count to max_digits, according to ctrulib and hardware testing.
The text shared memory wasn't supposed to be cleared according to my comparison with the LLE swkbd. This can cause issues in certain games such as Harvest Moon.
A null terminator is added to the text copied to mark the end of the string.
Fixes#4959
Previously options for video dumper and audio decoder is separated, but I forgot to split this `find_package` call so that the other libraries won't be necessary when only using the audio decoder.
This single line mode is aimed at restoring the intended behavior with Small or None icons. Line breaks will be replaced with commas (Region row) or spaces (Name row). One can toggle this option in UI configuration.
This option was intended for enabling optimizations when all rows are granted to have the same height. In our case this is not true, and therefore the behavior is actually undefined. Different versions of Qt handle this differently. Newer versions of Qt tend to hide contents that are too big in height, which goes against our wishes. Thus, it's probably the best to disable this option so that things don't go wrong if we ever decide to update Qt.
