 // Note that decoders in the |filter_collection| are ordered. The first
 // audio/video decoder in the |filter_collection| that supports the input
 // audio/video stream will be selected as the audio/video decoder in the media
 // pipeline. This is done by trying to initialize the decoder with the input
 // stream. Some decoder may only accept certain types of streams.
