A screencasting software for X. It can record audio through ALSA, OSS or the JACK audio server. It is the only screencasting software able capture through jack and thus is important for pro-audio video tutorials. RecordMyDesktop only outputs to Ogg using Theora for video and Vorbis for audio.
RecordMyDesktop is a CLI tool but there are two GUI interfaces available, gtk-recordmydesktop and qt-recordmydesktop.
The packages recordmydesktop, gtk-recordmydesktop and qt-recordmydesktop can be found in [community] for both i686 and x86_64.
The basic usage isn't too hard and it provides a man page. Here's a simple example using jack for audio capture:
recordmydesktop --use-jack system:capture_1
Current versions behave weird and need strange parameters to work properly. Try this for non-choppy capture:
recordmydesktop --use-jack system:capture_1 --v_bitrate 2000000
Audio record is lagging
If it appears that you have lags (error message when starting from the shell: Broken pipe: Overrun occurred.) in your audio record (often with Intel onboard cards) then it might help to change the audio device. This can be done in two ways.
1. Assuming that the terminal version is used then recordmydesktop should be started with the following command.
$ recordmydesktop --device plughw:0,0
2. If a GUI is used then you can change the device from DEFAULT to plghw:0,0 in the audio tab of the settings.
More information on this issue can be found here.
Audio record still lags and lose synchrony with the video
For my Intel card, using the plughw:0,0 device as described above worked partially. You might try this (which worked for me):
recordmydesktop --device plughw:0,0 --freq 22050 --channels 2
It seems the trick was to specify the correct number of channels generated by the input source -- in my case, a stereo mic.
