ChangeFPS speed isues

[Oletros]

I have an XP 2400+ and the encoding speed I have is 70-80 fps moreless.

But when I use the command ChangeFPS(15) when I want to encode to view divs on mi PocketPC the speed drops to 6-8 fps.

Is this normal?

ChangeFPS does no processing, but it depends on your source - you are actually seeking in your material, when dropping frames. I would imagine AviSource gets quite slow.

You could try using DirectshowSource it shouldn't suffer as much, since it will continue decoding on skips that are less than 10 frames.

When I use ChangeFPS with avi material to reencode it has no dropping issues but when I use it with mpegSource it has those dropping issues

That's because AviSource does intelligent prerolling (mostly thanks to Avery Lee's code I think). The issue has been fixed, and will be in the next CVS-binary.

i have quite similar problem (and don't want to start new topic :D )

using mpegsource and changefps actually just slow down and won't drop any frames, can anybody confirm this?

[sh0dan]

mpegsource may have trouble seeking. You should also try the new version (I'll build one tomorrow for you).

thx, eagerly waiting, btw if it needs just compile (with minor mods) i can do it myself

I had to test it a bit, since I did some housecleaning some places. But now it's up. (November 26th CVS Binary)
