29 /** A helper class for writing to StereoPictureAssets progressively (i.e. writing frame-by-frame,
30 * rather than giving libdcp all the frames in one go).
32 * Objects of this class can only be created with StereoPictureAsset::start_write().
34 * Frames can be written to the MonoPictureAsset by calling write() with a JPEG2000 image
35 * (a verbatim .j2c file). finalize() must be called after the last frame has been written.
36 * The action of finalize() can't be done in MonoPictureAssetWriter's destructor as it may
