- the same goes for audio: you mix .aac with .mp4, of course .mp4 could also include mp3 or mp2 audio for example, so this might confuse people in some situations (and maybe you want to add the .m4a extension too (.m4a = .mp4) IF mp4box knows the .m4a extension (dunno))
- you might also want to add .3gp support to the input options
ok, no problem.

it's like this :

Code:
code:00:00:00.000 Some Chaptername for Chapter 1
00:00:00.880 Some Chaptername for Chapter 2
00:00:02.400 Some Chaptername for Chapter 3
00:00:06.720 Some Chaptername for Chapter 4
00:00:08.840 Some Chaptername for Chapter 5
I decided to name it "GPAC format" to avoid the confusion with subtitles format...Yes I know it's not clear. If you have a good name...

- for container files (audio and video): .avi, .mpg, .mp4 there is also the possibility to choose what you want to import in mp4box (for .avi and .mpg its #audio or #video, for .mp4 its the trackid, cause if this is not defined, both audio and video (or better said all streams in the container) will get imported from the container)
you can solve this by adding always #video to .avi and .mpg inputs in the video tab
the same for the audio tab (add #audio to .avi, but you can also import audio-only that way from .mpg files (mp2 audio) so it might be a good idea to add this (.mpg and always adding #audio) to the audio tab too)
for .mp4 files you need to define the trackid, which is a more difficult task actually (audio-only .mp4 files normally always use the trackid 1 for the audio stream), but for audio+video .mp4 files it becomes more difficult, so you might want to leave this as is
I plan to add some import/dump functions in a new tab...so, yes.

IIRC, there is no official extension for 3gp files. I checked -h format command to have these extensions.

You read my thought...Yeah, it's expected.

we have already the cmdl in this tab...

maybe...

No, it doesn't work. I disable this option for the moment.
