I think you should have three info blocks: video streams, audio streams and subtitles (if container supports their embedding). Sort naturally or by vid/aid/sid if present.
You shouldn't multiplex video and audio streams since any video stream can be combined with any audio stream. In terms of xml you can have container as root element, which embeds streams grouped by type. -- Best regards, Konstantin Gribov. 28.03.2014 1:29 пользователь "Nick Burch" <apa...@gagravarr.org> написал: > On Thu, 27 Mar 2014, Konstantin Gribov wrote: > >> Some containers (like matroska/mkv) tags audio and subtitle streams with >> language tag and some comment.
