linux screen->video capture software

[D.P.]

I have some simulations I would like to record from the simulation window into a movie. I need a screen capture device that can capture my X-windows desktop.

I am using Kubuntu.

Thanks in advance.

installing, looks promising...

ok, it appears to work?
Any good ogg to mpeg converters or off players?

actuall, it seems to generate an empty file

 

[D.P.]

will try it out tomorrow at work

Got a meeting with the supervisor on friday and have to show off what Ihave been working on, the last time I did this I releid on live demos of my software... bad idea

Did the empty file have an extension?

it was a .ogg file, but was always size 2.7kb, so contained no actual data. Was very strange. The newest version looks just perfect for me, able to record from sub-windows. I tried to compile it but it requires lots of dependencies, some which apt-get doesn't find- these don't have packages and need o be compiled as well, and then some of them have further dependencies...

I'll investigate further tomorrow but can't spend too much time.

with istanbul it seems to record only 1 or 2 frames, chew up a load of CPU cycles, and general just hang.


vnc2swf seems to record soemthing, but it not my actual desktop

record desktop seems to be better, but it is not saving anywhere near eno0ugh frames...
Saved 57 frames in a total of 1447 requests

I get a crappy slide show effect. I guess gthe problem is it can't get the data fast enough. I should problem just write some code to export frames as jpeg and then to a post conversion.

Try vnc2swf!

I did, but it doesn't record my desktop per se, just some fanciful desktop that has Ark open and firefox... nokt the current desktop that i am actually displaying. Apart from that it seems fine!

Ok, its working now using x11vnc instead of vncserver (and running it sudo just incase)

Records movies but the same problem is that it is just too slow to be useful. I recorded at 600x400 res, and it does about 1 frame every 3 seconds or worse.
I gess this nis just a generic problem accessing the memory. Looks like I will have to make some code which saves snapshots ever few frames. and post convert.
