Could you please add a comment.

I wanted to copy the comment from media::DemuxerStream, but did not find any
comment there. Can you suggest an appropriate comment? I am not too sure what
this function is supposed to do in generic terms.

Fair enough :) How about:

Enables converting bitstream to a format that is expected by the decoder. For
example, H.264 bitstream based packets into H.264 Annex B bytestream format.
