frame serving with jitter

March 22, 2007 | 6:33 pm

hi list, i have been using avisynth for some time now. for those on windowz
with any intrest in video i highly recommand taking a look at it.
its a scripting language for video post processing.
for example a script which does resizing, you write in notepad and can run
on any mediaplayer.

AVISource("somevideo.avi")

# resize the dimensions of the video frame to 320×240
LanczosResize(320, 240)

but its most powerfull feture is it is capable of frame serving.
question is there a way to make it work with jitter. or any other
frame server which is qt compatible.

what is ‘frame serving’ (ah, google, thank you!) ? Ive never heard
of this. Sounds like VideoScript (a bit) http://www.videoscript.com/
intro_vs.html

it sounds like pipeing data in unix.

I would love to know if this is possible. This could be a great
solution for moving data between apps, like a local loopback but for
video.

Save to disk, execute commandline, read back in. Should be easy to
make an mxj example (pending the 4.6.3 Max release which fixes
commandline calls on MacTel, that is).

See main list and mxj threads for calling commandline functions from
mxj (or with the shell and other externals avail for this purpose).

Hrm. Well, the pipes that are used in things like ffmpeg and other
script wrappers for video transcoding solutions never touch the disk.
But yes, that is a totally valid technique with respect to jitter. I
suppose I should have stated in my question without hitting the
drive :P There may be a way to open some pipe into java for doing
this. Oh, if I had time :)
