Input helpers

Includes lookup, media playback control (handles MediaFileInput, AudioFileInput, and CavPlayerInput uniformly), and generic reflection-based property/command access.

Function	Returns	Description
`GetNamedModel(modelName)`	`NamedModel or null`	Returns the named model from `NamedModels`, or null if no match exists.
`SetObjectProperty(op, propertyName, value)`	`bool`	Sets a property on the given object using reflection and TypeDescriptor-based invariant-culture string conversion. Returns false if the object is null, the property does not exist, or conversion fails.
`SetObjectProperty(targetName, propertyName, value)`	`bool`	Resolves a named model via `GetNamedModel` and sets a property on it using reflection and invariant-culture string conversion. Returns false if the target name or property name is empty, the target is missing, or conversion fails.
`CallObjectFunction(op, functionName, values)`	`object or false`	Invokes a method on the given object using reflection. Returns the method's return value on success, or false if the object is null, the function name is empty, the method does not exist, or invocation throws.
`GetObjectProperty(op, propertyName)`	`object or null`	Reads a property value from the given object using reflection. Returns null if the object is null, the property name is empty, or the property does not exist.
`GetInputByName(name)`	`AbstractInput or null`	Returns the input with the given name, or null if no input matches.
`GetInputById(Id)`	`AbstractInput or null`	Returns the input whose `Id` matches the given GUID string, or null if no input matches.
`GetMovieInputByName(name)`	`MediaFileInput or null`	Returns the named input as a `MediaFileInput`, or null if no input matches the name or the matched input is a different type.
`StartMediaPlayBack(name)`	`bool`	Starts playback on the named media input. Supports `MediaFileInput`, `AudioFileInput`, and `CavPlayerInput`. Returns true if a Play command was dispatched; false if the input is missing, of a different type, or its play command is not currently executable.
`ScheduleMediaPlayBack(name, delayMs)`	`bool`	Schedules a delayed start of a media input. The input must exist and be a `MediaFileInput`, `AudioFileInput`, or `CavPlayerInput`. Only one scheduled start per input is allowed at a time; subsequent calls for the same input are ignored until the pending entry fires or is cleared via `ClearScheduledMediaPlayBacks`. The scheduled start fires only while the project's `PlaybackState` is `Running`.
`ScheduleMediaStop(name, delayMs)`	`bool`	Schedules a delayed stop of a media input. The input must exist and be a `MediaFileInput`, `AudioFileInput`, or `CavPlayerInput`. Only one scheduled stop per input is allowed at a time; subsequent calls for the same input are ignored until the pending entry fires or is cleared via `ClearScheduledMediaPlayBacks`. Scheduled starts and stops are tracked independently — an input may have one of each pending. The scheduled stop fires only while the project's `PlaybackState` is `Running`.
`ClearScheduledMediaPlayBacks()`	`bool`	Clears every pending scheduled media start and stop, regardless of input. Also invoked from `Clear` so a project switch never leaves stale scheduled actions behind.
`StopMediaPlayBack(name)`	`void`	Stops playback on the named media input on a background `Task` (fire-and-forget). Supports `MediaFileInput`, `AudioFileInput`, and `CavPlayerInput`. No-op if the input is missing, of a different type, or its stop command is not currently executable.
`PauseMediaPlayBack(name)`	`bool`	Pauses playback on the named media input. Supports `MediaFileInput`, `AudioFileInput`, and `CavPlayerInput`. Returns true if a Pause command was dispatched; false if the input is missing, of a different type, or its pause command is not currently executable.
`MediaIsPlaying(name)`	`bool`	Returns true if the named media input exists and its `MediaPlayerState` is `Playing`. Returns false otherwise (including when the input is missing or not a media file/audio/CAV input).
`ExecuteInputCommand(selectedInput, buttonName)`	`bool`	Executes a named `Command` button on the given `AbstractInput`, using reflection. Returns true only if the command was found and executed successfully.
`CheckIfAllMediaFileInputsArePlaying(minSeconds)`	`bool`	Returns true if all media file inputs in the project are currently playing and have played for at least the specified number of seconds. Designed for polling from OnRenderFrame in test scripts to wait for media files to be ready before performing actions that depend on them.
