hi,
to add some more to my confusion this 1440 x 1080 clip plays faultless,
even when playback has been stopped and so on.

ideas why this is so anyone?
cheers

Hey guys,
Here are my results. One note: I encountered the 1080i playback bug
that Marcin Kostur reported a few weeks back, wherein 1080i output plays
back normally (~30fps) from the start of the video, but slows down
considerably to 2fps if you choose a random point within the video.
This bug documented here:
http://bugs.cinelerra.org/show_bug.cgi?id=348
However, this bug has not been resolved, other than in the fix that
Marcin found:
https://init.linpro.no/pipermail/skolelinux.no/cinelerra/2006-November/008696.html
Could any of the programmers update Bug 348 to let us know if this fix
is sufficient?
thanks,
scott
PS - here are my results of the playback:
System:
Cinelerra CVS, SVN r947
Dell 400SC, 3.2Ghz, 800FSB, 2GB 400Mhz, Dual DDR, ECC
250GB SATA system drive
Nvidia GEForce 7600GS 8xAGP video card, 512MB memory

Playback every frame/Decode frames async: unselected
Compositor: 75% spanned across two monitors
Playback FPS (from beginning of video): OpenGL: 30.15, XV: 29.4
Playback FPS (from 3 seconds into the video): OpenGL 2.21, XV: says
29.94, but that is not correct, as playback is slowed considerably
When I playback the video, I get a bunch of these messages in the
terminal window in which I started cinelerra:

I got 29.94 fps. Compositor at 75 between 24->28 fps when compositor was at a scale of 50 % on a Intel(R)
Pentium(R) D CPU 2.66GHz
When at 100% I get 19 fps with the picture going over both screens (dual
monitor) and 24-25 fps when compositor on 1 screen, (but whole picture
not visible)
Video Driver: X11-XV
Play every frame is selected
Decode frames asyncronously unselected (REALLY slow when selected!)

Using Fedora Core 6, and livna repository to satisfy required libraries.
Compiling cinelerra with the following script:

Though /proc/cpuinfo shows me that I don't have sse3 (which nocona
requires!) so I am not too sure of the stability..

o.k. is there any way to understand what the bottlenecks on the
hardware side
are. like cpu, hd-speed or ram and so on?
