They mangle the mp3 header in a non-standard way to save a few bytes.
People who care about space so much should just use a more efficient
codec.

This option allows to add a prefix to the segment list entry filenames.

Also set by default the list entry filenames to the corresponding
segment basename, consistent with the HLS muxer.

Based on an idea by Steven Liu <lingjiujianke@gmail.com>.

Opus Pre Skip is exported in AVCodecContext->delay similar to how
it is done for matroska. Doing the same for ogg too.
