set_output_state

Creates a new CodecState with the specified fmt, width and height as the output state for the decoder.

Any previously set output state on this will be replaced by the newly created one.

If the subclass wishes to copy over existing fields (like pixel aspec ratio, or framerate) from an existing CodecState, it can be provided as a reference.

If the subclass wishes to override some fields from the output state (like pixel-aspect-ratio or framerate) it can do so on the returned CodecState.

The new output state will only take effect (set on pads and buffers) starting from the next call to finish_frame().

Parameters:

this	a Decoder
fmt	a Format
width	The width in pixels
height	The height in pixels
reference	An optional reference CodecState

Returns:

the newly configured output state.
