Methods#

virtual FrameInfo get_output_info() = 0

Returns output information of the source.

virtual void set_output_info(const FrameInfo& info) = 0

Enables post-processing (ex, resize, color-conversion) to specified format and tensor shape.

Parameters:

info	Output frames information

virtual FramePtr read() = 0

Read one frame from the source.
