Screencasting your Ubuntu Desktop: It's easy

[patrickballeux]

Me too, the audio/video sync is a nightmare to solve. Finally got it right in the ScreenStudio 0.9.1.

Cool stuffs! But I wonder why only flv is supported. flash is very problematic on Linux and many of us can't wait for its demise.

[patrickballeux]

FLV is mostly used for RTMP. Flash does not matter as browsers are not able to play streams without the Flash plugin

i made a comment on your youtube video but i'll post it here as well, i see in your avconv command you don't set the keyframe interval, both twitch and hitbox are very sensitive with this setting and if it's not set many times a black screen is what the websites player will show. just an fyi. If you're looking for any tips or help I would strongly suggest peaking at simplescreenrecorder source code

I see the problem. The issue is that ScreenStudio was trying to use the display 0.1 which does not exists actually. This has been fixed in 0.9.3.

[patrickballeux]

I am working on the next release of ScreenStudio 1.0 and it will be great!

Basically, I am trying to build a pre-configured setup for any service so that anybody can easily broadcast their desktop.

Have a look at my youtube channel for the latest preview on ScreenStudio 1.0: http://youtube.com/patrickballeux

[patrickballeux]

ScreenStudio 1.2.0 is now available. This is a major update over the previous versions.

Note: The PPA is currently broken as some dependencies are missing. It will be updated shortly.
