I'm currently creating content and hinting mp4 files in Linux. The
basic steps are:
1) Create content and split into m4v and aac files.
2) Use mp4creator to create and hint the mp4 output:
mp4creator -c audio.aac -hint movie.mp4
mp4creator -hint -I video.m4v movie.mp4
mp4creator -optimize movie.mp4
mp4creator -list movie.mp4
and you get somthing like:
Track Type Info
1 audio MPEG-4 AAC LC, 18.320 secs, 3 kbps, 44100 Hz
2 hint Payload mpeg4-generic for track 1
3 video MPEG-4 Simple @ L1, 21.880 secs, 1000 kbps, 320x240 @
25.00 fps
4 hint Payload MP4V-ES for track 3
5 od Object Descriptors
6 scene BIFS
I end up with a file that I can stream from DSS and view it on a web
page with the Quicktime plugin.
The problem between these types of mp4 files and ones exported from QT6
is that when you click on the timeline in the QT web plugin, it jumps
cleanly around using the Qt6-derived mp4 file, but with the
mp4creator-derived mp4 file when you click on a new location on the
timeline, you only get a few blocks on the video from the new location
on the timeline and then when you hit play it takes about 5 seconds to
catch up and update the entire video as it's playing on the web page.
Are there any suggestion on making mp4 files that are more
'QT-compatible' from Linux so you can jump around the files with the web
plugin? (My videos are anywhere from 30 minutes to 3 hours so you need
to be able to jump around). If not, is there anyway in OSX to write a
shell script to Hint a file assuming it is automounted on an OSX machine
(droplets etc don't seem to work as then you need human interaction).
Thanks,
Bruce
