Figuring one of you smart people will know -
I need to turn mpg video from a camera into a video DVD as fast as I
can, under the direct control of my code.
If there actually existed licencable code libraries to do
this on Mac OS X, that is what I would have done - but there don't
appear to be any, not that I could find. The whole exercise has been
this slow irritating process of me discovering more and more of what
Apples frameworks and built in tools don't do, and having to add more
and more open source tools to the mix.
Currently, I'm using a chain of open source programs - ffmpeg
to turn the mpg video into a .VOB, dvdauthor to turn a collection of
VOBs into a full video dvd, mkisofs to create a video dvd format
image, then I burn the image using Apples video burning code. ffmpeg
in particular is a pretty time consuming process.
Now, my clients are comparing the process unfavourably to
just using Toast or something (which none of us want to do for a
bunch of reasons, but we really need this process to be fast).
I'm not sure how to make ffmpeg to go faster (currently the
big time sticker), or even that clear on what it is actually doing
that takes so long (isn't dvd video basically mpeg2 video anyway? And
there is no resolution changing, so what is it doing that takes so
long?). Anyone more familiar than I with this stuff?
Cheers
David
