View Full Version : MP4Box not behaving as expected for iPod

Hello, I'm trying to create a file that plays on the iPod / iTunes / Quicktime that includes soft subtitles, chapters, and is anamorphically stretched. There seems to be minor issues with all 3 aspects. The command line I use is:

MP4Box.exe -ipod -par 1=40:33 -add "1.mp4#1:lang=en:fps=29.970" -add "1.mp4#2:lang=en" -add "1.srt:lang=en:layout=776x40x0
x-1" -add "1.txt:chap" -new "1.m4v"

On subtitles, the layout is supposed to make them the full width of the video, but because I used the -par switch, the subtitles stay the same width as the original file (they do not stretch anamorphically). This is seen both in iTunes and Quicktime.

The chapters give me an error: "Error importing 1.txt:chap: End Of Stream / File". The chapter file is in OGG format. I tried saving as ANSI and as UTF-8, and the same error pops up. I wasn't able to test if it worked or not.

Using the -par switch, iTunes and the iPod (Touch and 5.5g) display the video correctly. It does not display correctly in Quicktime though. This is minor, as I do not intend to watch them in Quicktime, I was only using it to check if the subtitles and chapters worked =)

Anyway, if I am using MP4Box wrong, let me know.
