Previously the movie was started *after* core starts running, causing potential indeterminism.
Some desyncs are still not fixed; they may be caused by core timing. More investigation is required.
Since we do not have an overlay yet, it can be confusing whether movie is being recorded or played. This makes it clear.
Status messages (e.g. system archive missing) will be overriden, but that shouldn't be too important when recording movies.
Doubled the status bar updating frequency to provide a better experience. It now updates every second.
This is completely rebuilt, in order to allow setting author, displaying movie metadata, and toggling read-only mode.
The UX is changed to more closely match other emulators' behaviour. Now you can only record/play from start/reset (In the future, we might want to introduce 'record from savestate')
Also fixed a critical bug where movie file can be corrupted when ending the recording while game is still running.
Instead of specifying it when starting playback. This is necessary as
you can end up playing the movie even if you started as Recording
(for example, loading a state in R/O mode will switch to Playing mode)
Most other emulators handle this automatically in the frontend,
booting/restarting the corresponding game instead of reporting an error.
Therefore, remove these checks and errors from the module.
These fields are included in most emulators and required by TASVideos.
`input_count` is implemented by counting the number of 'PadAndCircle' states, as this is always polled regularly and can act as a time/length indicator.
TASVideos also require the input count/frame count to be verified by the emulator before playback, which is also implemented in this commit.
The read-only mode switch affects how movies interact with savestates after you start a movie playback and load a savestate. When you are in read-only mode, the movie will resume playing from the loaded savestate. When you are in read+write mode however, your input will be recorded over the original movie ('rerecording'). If you wish to start rerecording immediately, you should switch to R+W mode, save a state and then load it.
To make this more user-friendly, I also added a unique ID to the movies, which allows each movie to have an individual set of savestate slots (plus another set for when not doing any movies). This is as recommended by staff at TASVideos.
* service/apt: Add GetModule and GetAppletManager
These will be used to retrieve and set deliver args across system resets (which are currently implemented as complete restarts)
* applet_manager: Implement DeliverArg
`flags` was added to `ApplicationJumpParameters` as flags 0x2 is handled differently from 0x0.
* service/apt: Add ReceiveDeliverArg, implement GetStartupArgument
Some based on guesses.
* Address review comments
* kernel/thread: Change owner_process to std::weak_ptr
Previously this leaked almost all kernel objects. In short, Threads own Processes which own HandleTables which own maps of Objects which include Threads.
Changing this to weak_ptr at least got the camera interfaces to destruct properly. Did not really check the other objects though, and I think there are probably more leaks.
* hle/kernel: Lock certain objects while deserializing
When deserializing other kernel objects, these objects (`MemoryRegion`s and `VMManager`s) can possibly get modified. To avoid inconsistent state caused by destructor side-effects, we may as well simply lock them until loading is fully completed.
* Fix silly typo
Somehow this didn't break?!
The deep recursion has caused issues in certain games with large numbers of files, especially with MSVC builds.
Previously the recursion depth is about equal to the number of files present. With this the depth should be about equal to the maximum depth of the directory structure of the RomFS.
I'm not sure why we decided to have a boolean here, but apparently that wasn't the correct behaviour. According to HW tests, the Software Keyboard simply displays the default text when the button text provided is empty (**not necessarily all zero**). For example, if you set a text for one of the buttons and leave others empty, the button you set will have your text, while others will have their default texts. Removed the boolean and updated frontend code to make it correct.
* 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).
