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
Project Format: 1080i preset
Driver: X11-OpenGL or X11-XV
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!)
Video Card: nVidia Corporation GeForce 6200
Dual monitor, both @ 1280x1024
nvidia module version = 1.0.9629

/sbin/hdparm -t -T /dev/hda

Using Fedora Core 6, and livna repository to satisfy required libraries.

Compiling cinelerra with the following script:

#!/usr/bin/bash
echo configureing for pentium4
# --with-external-ffmpeg
../hvirtual/configure --prefix=/usr --enable-x86 --enable-mmx --enable-freetype2 \
                      --with-buildinfo=svn \
CFLAGS='-O3 -pipe -fomit-frame-pointer -funroll-all-loops -falign-loops=2 -falign-jumps=2 -falign-functions=2 -ffast-math -march=nocona -mfpmath=sse,387 -mmmx -msse' \ CPPFLAGS='-O3 -pipe -fomit-frame-pointer -funroll-all-loops -falign-loops=2 -falign-jumps=2 -falign-functions=2 -ffast-math -march=nocona -mfpmath=sse,387 -mmmx -msse' \ CXXFLAGS='-O3 -pipe -fomit-frame-pointer -funroll-all-loops -falign-loops=2 -falign-jumps=2 -falign-functions=2 -ffast-math -march=nocona -mfpmath=sse,387 -mmmx -msse'


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?

when i play the scene_1_shot10 clip / MPEG-2 19Mb/s 1080/24P (89MB)
i get frame rates around 17 fps. my box is a dual amd64 4800. can anyone play these
at 30 fps? on which hardware?

thanks

I got 13fps on my AMD64 X2 4600.
