notice that track ID 4 to 7 are missing...the difference between a "tx3g" subtitle track and an "apple" subtitle track is "text" in first one and "sbtl" in second one in "moov\trak\mdia\hdls\componet subtype" atom...

I added detection of "sbtl" subtype.
Note: subtype is for defining the kind of stream (Video, Audio, Text...), but what I saw is "tx3g" format in both cases ("text" or "sbtl" subtype). What I understood is that "text" in stsd is for "Apple Text" (the last 2 text tracks). In the case of "sbtl" subtype, I fill the "Muxing Mode" field with "sbtl", so you can detect if this is tx3g with "text" subtype (no Muxing mode info, this is the "default" muxing mode), tx3g with "sbtl" subtype (Muxing Mode info, this is not the "default" muxing mode), and text (Apple Text?) in "text" subtype.
Too much identifiers in MPEG-4!!!
Note about languages: I added language support for this kind of index ("old" Apple method, was implemented but deactivated because I had no file for it, now I have a file
)
Note about text streams: VLC displays only 9 text streams, 1 less than me; Text #9 (Track #12) is not handled, this is the same format definition as Text #10 (Track #13), if you have an idea of the reason...
