Screencast Problems (RecordMyDesktop - Demorecorder)


Hello,

I have tried a lot of software on linux for screencasting and the ones with best results are demorecorder and qt-recordmydesktop

the first one exports nicely but I can not convert to any other format other than the default unreadable format of the program
Code:
[ahmad@localhost demorec]$ demorec-to-flv-with-player test test.flv
/opt/DemoRecorder/lib/exporter/methods/FLV/framebuffer.sh: line 50:  8059 Segmentation fault      $DEMOREC_DIR/auxbin/drvfb :$displaynum $args -fp $X11FONTPATH -ac -terminate > /tmp/drvfb.log 2>&1
/opt/DemoRecorder/3rdparty/bin/lame -r -s 22.050 --bitwidth 16 -m m --silent --abr 32.000000 -x -t /home/ahmad/tmp/drexpPFtjUF /tmp/drSoundEncoder.8056.mp3
Assuming raw pcm input file : Forcing byte-swapping

while qt-recordmydesktop outputs only .ogg file which are unreadable on windows so far using a lot of software ie: jetaudio, winamp, windows (those are the major names) but it runs with no problems on linux
another problem with this program is the low recorded voice (I guess this problem is with the whole computer because there was no significant difference between the two programs)

id there a differnce between

How can I make my screencasts viewable on windows?

Offer to Help with crash of the DemoRecorder export filter and Sound Recording Volume

Hello AGazzaz,

I am the author of DemoRecorder so I can probably help you out with the crash of the export filter which you showed in your email.

Once the crash is fixed you can export to Flash/FLV ( as attempted with the shell-log in your post ) or to AVI, both resulting in videos which can be played back both on Linux and Windoze. (as you have asked for playback under Windoze)
( the AVI even works with the Windoze Media Player... and of course with Linux players such as gxine )

For getting the crash fixed please send me the DemoRecorder-recording called "test" in your example. I will try to reproduce the crash with this example, then fix it and make a prerelease containing the fix available for you.
( if the example "test" it is too large for sending by email please tell me and I will give you instructions for uploading. )
Since an original DemoRecorder-recording is a directory of files, please create a tarball of this directory.

Also I can probably help with with the recording sound volume. Most of the time, the mixer settings have to be adjusted. (please send me a screenshot of your current mixer settings or post it here). Sometimes the microphone signal is simply too weak for the sound card. Then a microphone preamplifier is needed between microphone and soundcard.

Best regards,

Chris
