On the KDE3 version I can have 2 HDV streams playing a dissolve in near realtime.



KDE4 version with no project open, doing nothing idles between 40-95% of CPU (mostly 80%). RAM stays stable at around 45mb.

Playing 1 video clip goes at about 2 frames a second.

I'm running Kubuntu Hardy 8.04.1 Remix with an intel CPU and an ATI HD4870 using fglrx on 4gig of ram.

Kdenlive was installed with the new KDEnlive compiling wizard. There are no errors in the konsole, but the process runs as root and refuses to shut down, even with kill pid.



Is there anything more I can provide help here?

Running the builder wizard again to update to revision 2380 seems to have fixed this.



Hooray!

Saw your problem was updated, but how did you get that ffmpeg version? It is in the high 14000's currenly, so?



I added a --version option to kdenlive_start, btw, which reports the versions (Version 0.4.0 at kde-apps).

Hmm... not sure. Maybe I just copied it down wrong or something. Anyway, after updating my ffmpeg version now returns revision 14845.



Any idea if posting bugs on the bug tracker is of any use to anyone yet or is it still a case of "We know it's got bugs. We're working on it."?

No, no idea. I usually tend to bugger the devs on the mailing list - it is my experience - from several different projects - that this works better than registering a bug. Which is very much a pity, actually: in my work life, I use Bugzilla extensively, but it is my experience, that not many open source projects understands how to work well with that kind of tool.



And, obviously, since the devs decided to use a bug tracking tool, they probably do not like to be buggered on the mailing lists. :-(

Same problem, display is pretty slow for some unknown reason. Especially for HDV. Kdenlive 0.6 did not have this kind of problem.
