## Detailed Description

A/V sources are elements, which can be used to conveniently pass audio or video frames from one program module to another. They do implicit format conversion and optimized buffer handling.

A module, which provides A/V frames, creates a source module and tells the native format in which it provides the frames. If you want to obtain the frames from the source, you tell the desired output format and if you intend to overwrite the frames.

To obtain the frames, you pass the address of the pointer of the frame. If the pointer is NULL, it will be set to an internal buffer.

The return value is of the type gavl_source_status_t, which can have 3 states depending on whether the stream ended (EOF) or a frame is available or if no frame is available right now. The latter can be used to implement parts of the pipeline in pull mode (the default) and others in push mode.
