...and ignore it. The main purpose is for retrieving per-track replaygain tags. Other than that per-track tags are not used or accessed by the playback core yet. The demuxer infrastructure is still not really good with that whole synchronization thing (at least in part due to being inherited from mplayer's single-threaded architecture). A convoluted mechanism is needed to transport the tags from demuxer thread to user thread. Two factors contribute to the complexity: tags can change during playback, and tracks (i.e. struct sh_stream) are not duplicated per thread. In particular, we update the way replaygain tags are retrieved. We first try to use per-track tags (common in Matroska) and global tags (effectively formats like mp3). This part fixes #3405.
