VideoWriter.empty(): factory
VideoWriter.fromFile(String filename, String codec, double fps, (int, int) frameSize, {int? apiPreference, bool isColor = true}): factory
VideoWriter.fromPointer(VideoWriterPtr ptr): factory

hashCode → int: The hash code for this object.
no setterinherited
isDisposed → bool: Whether this object has been disposed.
no setterinherited
isOpened → bool: no setter
props → List<Object?>: no setterinherited
ptr ↔ Pointer<VideoWriter>: getter/setter pairinherited
ref → VideoWriter: no setteroverride
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

dispose() → void: Releases the underlying native resources. Idempotent: calling it more than once is safe, but the object must not be used after dispose.
inherited
freeNative() → void: Frees the native resources owned by this object. Subclasses implement the concrete free logic here; callers must use dispose instead.
override
get(int propId) → double: Returns the specified VideoWriter property.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
open(String filename, String codec, double fps, (int, int) frameSize, {int? apiPreference, bool isColor = true}) → void
openAsync(String filename, String codec, double fps, (int, int) frameSize, {int? apiPreference, bool isColor = true}) → Future<bool>: Available on VideoWriter, provided by the VideoWriterAsync extension
release() → void
set(int propId, double value) → void: Sets a property in the VideoWriter.
toString() → String: A string representation of this object.
inherited
write(InputArray image) → void
writeAsync(InputArray image) → Future<void>: Available on VideoWriter, provided by the VideoWriterAsync extension
