So far mkvmerge doesn't present the cores therefore the users cannot choose if they want to mux — for example — TrueHD with AC3 core (in one .mkv file, but separately of course) or only one of them. The same situation applies the core of DTS which can't be chosen as a single to mux; it is important to note that many people don't need lossless DTS-HD MA (which size is often very large) ===> that's why the single DTS core (+/- 1GB) is absolutely sufficient and rewarding.\n\nCurrently when someone wants to add the core to mmg, previously has to extract it using tsMuxeR (wasting time, but necessary) or use MakeMKV [which shows, and allows to select (or not), the core] instead of mkvmerge GUI. For me and other people (who really like and appreciate mkvmerge GUI) that situation is definitely unacceptable. Our life would be much easier and faster if we could decide which »hidden« audio track to select and mux.\n\nSummarizing: I know that this feature is very difficult to implement because it would require massive re-writes of a lot of code, but I'm convinced that it will be possible in the far future.\n***We will find a way. We always have*.** ☺"},"comment":{"url":"https://api.github.com/repos/mbunkus/mkvtoolnix/issues/comments/74429374","html_url":"https://github.com/mbunkus/mkvtoolnix/issues/1107#issuecomment-74429374","issue_url":"https://api.github.com/repos/mbunkus/mkvtoolnix/issues/1107","id":74429374,"user":{"login":"remuxer32","id":10992208,"avatar_url":"https://avatars.githubusercontent.com/u/10992208?v=3","gravatar_id":"","url":"https://api.github.com/users/remuxer32","html_url":"https://github.com/remuxer32","followers_url":"https://api.github.com/users/remuxer32/followers","following_url":"https://api.github.com/users/remuxer32/following{/other_user}","gists_url":"https://api.github.com/users/remuxer32/gists{/gist_id}","starred_url":"https://api.github.com/users/remuxer32/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/remuxer32/subscriptions","organizations_url":"https://api.github.com/users/remuxer32/orgs","repos_url":"https://api.github.com/users/remuxer32/repos","events_url":"https://api.github.com/users/remuxer32/events{/privacy}","received_events_url":"https://api.github.com/users/remuxer32/received_events","type":"User","site_admin":false},"created_at":"2015-02-15T18:22:30Z","updated_at":"2015-02-15T18:22:30Z","body":"Thank you for new builds.
