A method includes receiving an input media stream at a hardware encoder. The method also includes executing, at a processor of the hardware encoder, a headless browser to retrieve an instance of a dynamic web page that includes additional content. The method also includes storing the additional content at a memory that is accessible to the processor and encoding circuitry of the hardware encoder. The method further includes retrieving, at the encoding circuitry, the additional content from the memory and encoding the input media stream to generate an output media stream. At least one frame of the output media stream includes at least a portion of the additional content in conjunction with at least a portion of a corresponding frame of the input media stream.
