Is there a tool to extract chapter data and timecodes from m4v files?

FYI - Although they can be copied and played on any device w/o conversion or DMR removal these files show as "Protected" when i look at the file infromation. All I want is the Chapter data and coresponding timecodes that can be seen in "Quicktime Player" and iTunes.

Preferably a Windows app but Mac will do and preferably freeware.

Thanks.

See Quicktime (Windows) below.

Try mp4box or a gui for it like yamb, see http://yamb.unite-video.com/extract.html

Mplayer will list chapter info with the -identify command. I.e.:

$ mplayer w_ASL_20120115_03.m4v -identify -novideo -nosound
ID_CHAPTER_ID=0
ID_CHAPTER_0_START=0
ID_CHAPTER_0_END=7007
ID_CHAPTER_0_NAME=Title Page
...

You can get just the names with some filtering (should work on mac)

$ mplayer w_ASL_20120115_03.m4v -identify -novideo -nosound | grep NAME | awk 'BEGIN {FS = "="} ; {print $2}' > chapters.txt
Title Page
Summary
Title

atticushp,

This looks great, thanks for your help. Can you tell me what type of timecode it is outputting? What do numbers like (7007) correspond to. They don't appear to be frame numbers or seconds, but I could be wrong. Is there a way to convert this to minutes/seconds?

Thanks again,
