I need to make a couple of videos on how to use a website I wrote with audio. I installed Recorditnow, VLC and Istanbul but they all have the same problem which is very poor choppy frame rates while recording and when I preview the recorded video the audio goes pop pop pop and the screen corrupts if I change windows.

I have an ATI graphics card with the latest catalyst drivers, Ubuntu 10.04 Lucid Lynx

I did read on one forum that the problem may be that the ATI drivers do not allow hardware accelleration for libfb but the bug report was dead.

Does anyone else have a fix for this or can suggest an alternative?

I use recordMyDesctop with setting - Full shot at every frame: Yes

p.s. youtube accept .ogv files.

OpenGL is enabled.
I have the lastest ATI drivers so probably 12.3

I have found though that if I run ffmpeg from the bash it works perfectly

ffmpeg -s 1366x768 -r 30 -b 5000k -ab 128k -ac 6 -i -f x11grab $DISPLAY+1920 out.mpg

gives me a pretty much perfect record with sound so workaround has been found.

I guess the issues with the other desktop recorders is as you say the catalyst drivers and the mpeg bug

I remember I made a video with EVe , WOW and a video playing back in the day.I had Beryl for compositing and there was a plugin to record everything. Search a plugin for compiz or something like that. It's really a petty Beryl was far better than compiz, they merged the teams and a lot of cool features from beryl got lost.

Actually on further testing, the recorded video runs at around 1 fps so I'm back to square one again.....

Any other ideas or workarounds?

After some head scratching and playing around with things I've worked out a solution that works with me.

After installing GLC properly I worked out how to get it to run eve and I can do my thing from there. Only problem is that it seems to record things flipped vertically but one of the movie editors can fix that. Records the sound as well decently so I have a sort of solution.

I have been using ffmpeg for this. See here: https://forums.eveonline.com/default.aspx?g=posts&t=90176

You can use ffmpeg to record into a file, too. Streaming it live to a video broadcaster is just the cheery on the cake.

Loss is meaningful. Therefore is the loss of meaning likewise meaningful. It is the source of all trolling.

Doesn't work for me. There's a problem with the ATI driver. I did try ffmpeg but the fps went down to about 3-4 fps which is no good for any demonstration.

glc lets me record at around 20fps so about half of my normal but still acceptable. mind it's a heck of a work around just to demo a website......

Using an Nvidia card with Nvidia's own Linux driver can I get 35fp/s of a 1680x1050 screen with ffmpeg. This is with a running EVE client at 60fp/s but without encoding and only dumping the raw video stream to /dev/null. The bit rate for this is about 2GBit/s. Without the EVE client working its 3D magic can I grab at 57fp/s or 3Gbit/s. This only for a comparison.
