    To people having sound issues, make sure that the correct channel is enabled for capture in alsamixer*: type "alsamixer" in a terminal, then press [tab] or F4 to go to the capture devices panel, then check that the right channel (for instance "Mix" to record all sounds) has the word "CAPTUR" in red at its bottom. If not, select the channel with arrows and press [space]. Exit with [Esc], retry to record and enjoy.

    BTW note that ffmpeg is also able to capture the desktop*:
    Code:
    ffmpeg -f oss -i /dev/audio -f x11grab -s 320x240 -r ntsc -i :0.0 capture.mpg

    Re: Record your desktop with recordmydesktop ;)

    hi there,

    I've been able to capture my entire desktop comfortably with rmd.
    But just now I tried it again and the output was really sloppy, only showing a frame every 4 to 5 seconds on average.
    Now, neither while recording nor while playing the output-file (a 1280x1024 theora) was my cpu anywhere near the 10% (thats 10, not 100) hurdle.

    So why might that be? Any ideas?

    PS: I can record my desktop with ffmpeg without any problems.

    hey, that works rather nicely, too - thanks for the tip

    Re: Record your desktop with recordmydesktop ;)

    NOT WORKING... driving me insane!!!

    recordmydesktop --on-the-fly-encoding -v_quality 63 -v_bitrate 2000000 -fps 20 --full-shots --no-sound -workdir . -o foo.ogv
    I followed the tips in http://thefunkcorner.blogspot.com/20...mydesktop.html
    I tried lots of stuff and nothing worked properly.

    And for the moment, I'm not even talking about audio... just some decent video capture.

    The problem is that the recorded video seems like it's a fast forward recording. As if 10 seconds become one second.

    If I change the -fps to something like 8, I can get a "almost decent" recording with slow movement on the screen.


    What I would like to be able:
    to open a video file in smplayer and record the desktop as it plays, both video and sound.


    Any help?

    You can use FFmpeg:

    that sounds like the same problem I described a few posts before. If it is, than it has to do with the new version of libtheora. Apparently it handles things differently and all programs using it have to update the way they're handling it.
    Someone created a bug-report on the sourceforge-page of recordmydesktop http://sourceforge.net/tracker/?func...57&atid=861428
    And its widley discussed here within fedora: https://bugzilla.redhat.com/show_bug.cgi?id=525155

    Until the author updates rmd changing the bitrate to 200000 worked for me:
    Code:
    recordmydesktop --v_bitrate 2000000
    .

    By the way, I switched to ffmpeg, see link above. It gives me much better results in the quality of the video.

    That didn't work for me. Nor 200,000 nor 2,000,000 (you have said both values in your messsage).

    I'm also trying to go that way. Well, I already can, but there are still some pending issues.

    In any case, I had already done several screencasts using recordmydesktop and they're all choppy (ie, weird frame rates) and eat up lot of HDD. I would like to convert them.

    I tried
    ffmpeg -i input.ogg -vcodec libx264 -vpre hq -crf 22 -threads 0 out.mkv
    but the resulting video still ends up with weird frame rates, and in particular, it confuses mplayer which thinks it's 24 minutes when it's only about 12.
    The fact is that, if RMD and libtheora didn't sucked, the proper recording would have 24 minutes. But isntead it gets "fast play" and only takes about half the time.
    How do I fix this?

    Thanks for that been having a nightmare trying to get the gui one to work, or any of the screencap apps to be honest but this works perfect
