HowTo mux Subs into MP4 via MPEG-4 Systems

[Drachir]

You can find a sample here: subtitles in AnimationStream (https://sourceforge.net/forum/forum.php?thread_id=1284033&forum_id=327349)

Thanks for the link. But isn´t this a animationstream subtitle? Is this the same as an ttxt stream?

[Drachir]

No it isn't, this way ttxt is used.

To convert srt/sub to a BIFS animationstream you have to use "TextNode" in MuxInfo.

http://gpac.sourceforge.net/auth_text.phpUsing text streams within MPEG-4 scene description is much more tricky (is it?). You will add an ObjectDescriptor to your scene as you add an audio/video object, specifying the file name with the usual MuxInfo. Note: when using SRT/SUB, make sure you don't have TextNode specified in the MuxInfo, as this ALWAYS triggers subtitles to BIFS conversion and not 3GPP timed text.
The second step is controlling the new text object in the same way you control an audio or visual object. This is currently unspecified in MPEG-4, but GPAC handles this through the AnimationStream node. Instead of controlling a BIFS stream, you can start/stop/play the text stream with this node.

I want to make a dvd with subtitles and use of the mp4 container, but i'm not sure how to do this with nero. any ideas?
(Couldn't find anything on the forums)Then, with respect, you did not look hard enough....

Anyway, here's one place you can start: -
