hi scott,
to make things more complicated it looks like we're refering to differt
versions of libmpeg.
just upgraded to libmpeg3-1.7 ( hard masked - will say unstable ).
now i do not have playback problems with the "surfing" clip, but still
in some other ones.
my unqualified guess is that it all depends on the camcorder - there
codecs - anyhow.
trying to edit 3-1.7 i find the following code:
// Read up to current frame
mpeg3video_drop_frames(video, frame_number - video->framenum, 1);
break;
}
}
}
else
{
video->repeat_count = 0;
mpeg3video_drop_frames(video,
frame_number - video->framenum, 0);
should i try to change the "1" to "0" in the 2nd line?
cheers

hi jan,
I'm running Fedora Core 4 and use "yum" to install my dependencies.
Unfortunately, I don't know about Gentoo. The libmpeg3 I am using is
specific to Heroine Warrior (consequently, the Cinelerra CVS) and comes
with the source code from the subversion repository when you download
it. This version is libmpeg3hv-1.5.0:
ldd /usr/local/bin/cinelerra | grep mpeg3
libmpeg3hv-1.5.0.so.1 => /usr/local/lib/libmpeg3hv-1.5.0.so.1
(0xb7bb6000)
Unless someone else has been successful with using later versions of
libmpeg3 when building Cinelerra from source, I'm pretty sure you'll
need to use this older version that comes with the repository in order
for the source code to build properly.

hi scott,
in gentoo libmpeg3 is a separate ebuild. which version are you running?
mine is media-libs/libmpeg3-1.5.2-r3. maybe an update to 1.7 would also
work?
otherwise i have to to understand how to edit ( = apply the fix ) to the
source code - never done that before.
thanks

Jan,
You'd need to checkout the Cinelerra source code from subversion:
http://cvs.cinelerra.org/svnusage.php#anon
make the edit as specified in Marcin's email:
https://init.linpro.no/pipermail/skolelinux.no/cinelerra/2006-November/008696.html
to edit line 357 in libmpeg3/video/seek.c in the Cinelerra source
directory. Then recompile.
of course, to compile from source, you need all the programs Cinelerra
is dependent upon. For my Fedora system, I've listed them here:

hi,
same thing here. how and where could i apply the fix - in gentoo?
am not a coder but know how to use an editor;-).

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

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