|
|
* @brief This abstract class is the base class, used by all readers in libopenshot.
|
|
*
|
|
* Readers are types of classes that read video, audio, and image files, and
|
|
* return openshot::Frame objects. The only requirements for a 'reader', are to
|
|
* derive from this base class, implement the GetFrame method, and call the InitFileInfo() method.
