    Re: HOWTO: Proper Screencasting on Linux

    Hi varunvats,

    I've updated the guide to the new -preset syntax.

    Regarding the low fps, that's probably because you're not using the lossless_ultrafast preset. If you don't specify a preset, it...

    Re: HOWTO: Install and use the latest FFmpeg and x264

    @FakeOutdoorsman: If you make an independent Natty guide, you can then drop the libvpx building instructions as Natty has the latest libvpx version in the repositories.

    Re: HOWTO: Proper Screencasting on Linux

    This is probably because libx264 does not yet support the 4:4:4 color space; edges of very small and sharp lines might appear a bit blurred. Go ask the x264 developers to add it.

    Also, you can use strong quoting 'filter,filter...'. This way you won't need to escape the colon characters.

    You can encode to the new open format "WebM", which should give you much better quality than .ogg with Theora. Just replace libtheora with libvpx (assuming you followed the ffmpeg building guide, you...

    This happens when you are recording through pulse (bug?). If you're recording through microphone, replacing -i pulse with -i hw:0,0 will solve your problem.

    Even I tried capturing more than 30 fps and couldn't do it. There seems to be a bottleneck somewhere. You can ask the people at #ffmpeg on irc.freenode.net, they might be able to help.

    Frei0r filters integration has also been added. To enable it, you need to install the packages frei0r-plugins and frei0r-plugins-dev and build ffmpeg with --enable-frei0r.
