I have a .mp4 file with about 30 different languages timed text subtitles. How do I extract all 30 timed text subtitles using MP4Box 2.0? Is there a way to bulk extract the 30 timed text subtitles using MP4Box 2.0 at once?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

no, you would need a gui or something similar to do that. MP4Box has no option for bulk extraction (see: https://www.mankier.com/1/mp4box).

Thanks. I was able to extract using MP4Box GUI. Extractions doesn't name the languages in the SRT files. Is there a way to include the names of the different languages?

No clue, haven't used mp4box gui for 10+ years, but unless the subtitles are tagged with their language definitely not.

GPAC contributor here. Sorry I am late to the game...
MP4Box allows to extract the N-th text track using #textN. Example to extract the 30th subtitle track:
Code:MP4Box -add source.mp4#text30 -new sub30.mp4
Don't hesistate to post on our github issue tracker. You'll get some more responsive help there -
If you update to the latest GPAC, you will be able to do the following:
Code:gpac -i source.mp4 @@0#text1 -o sub1.mp4 @@0#text2 -o sub2.mp4 ... @@0#text30 -o sub30.mp4
Code:gpac -i source.mp4 @#text -o sub_$PID$_$Language$.srt
