This BSF is supposed to be used in conjunction with mp3_header_compress, which has been removed more than ten years ago in commit c6080d89009056530119ab794ad02e4d515c7754. It mangled the headers by removing the CRC field as well as fields that are supposed to stay constant for the entirety of a stream (which are put into extradata). This made these files unplayable; they need to be decompressed with the BSF first (which does not happen automatically). Even in this case the CRC does not get restored. I am not aware that such compressed files exist at all; therefore this commit removes the BSF completely.
