sbtlpatch: Display subtitles on Apple players

[micmac]

Hi all,

because Apple players don't use the handler type "text" to detect text subtitle tracks (instead they use "sbtl"), here's a tool to change the handler type. E.g. use MP4Box to multiplex all streams into an MP4 container, then use sbtlpatch to change the handler type.

The tool is command-line-only (suited for scripts etc). Changes can be reversed.

Regards
mic

P.S.: It doesn't really "patch" anything; sbtlpatch uses standard mp4v2 routines.
P.P.S: MP4Box (gpac) now (post 0.4.5) supports the different handler types as well.

sbtlpatch-0.2: - fixed a segfault on Ubuntu Hardy

sbtlpatch-0.3:
- this version needs libmp4v2 version 1.9.x

Hi! Is there an mp4box equivalent for linux-ubuntu? I don't know how to try your program unless I figure out how to create an mp4 file from my avi+srt...

Everything compiles fine (although I had to cp the libmp4v2.so.1 from /usr/local/bin to /usr/bin in order for your program to find it)

Hi! Is there an mp4box equivalent for linux-ubuntu?
MP4Box is included in the gpac package, so:
sudo apt-get install gpac

If you need version 0.4.5 or later, upgrade to Karmic or build MP4Box yourself.

Yeah, I figured it out a while ago here (http://manpages.ubuntu.com/manpages/jaunty/man1/mp4box.1.html). Trying to figure out the CLI part now... I will let you kno when I'll upload it to my iPhone

Edit:Found it, it is MP4Box -add input.avi -add sub.srt -ipod -new dest.mp4
Edit#2: Now iTunes refuses to add it in its library.... Damn you Apple!

Ok, everything works perfect! I tested it with english subtitles and it works great.

Thank you very much for this program!

Kudos to National Center For Accessible Media (NCAM) for squeezing Apple to cough the info!!! (http://forum.doom9.org/showthread.php?p=1292880#post1292880)
