[SOLVED] Trying to do basic screen recording

[harkelyn]

I don't need audio, just want to capture some desktop cursor movements on a webpage. Objective is to upload brief .mp4 clips in connection with software testing gigs.

I've tried setting up VLC Media Player as a Capture Device. I select Desktop, then select Stream, then New Destination, /home/username/Video/file name. For transcoding I select Video H.264 + MP3(MP4), and finally, Stream. VLC then seems willing enough: it offers the record button which I activate, and then I click into a Firefox window and move the cursor around briefly, then I stop the test recording.

In the course of these tests, 70 to 80 MiB data is being generated and saved either as .avi or .mp4. However upon subsequent playback using VLC, the video clip proceed as only a black screen with a footer, as shown in the example immediately below. I should be seeing a video clip which includes clicking over and moving the cursor in a Firefox browser window.

This is what plays back on a black screen after I set up VLC for a test video recording of my desktop web browser.

I've tried installing Byzanz, and Mageia Control Center indicates that Byzanz is now installed in Videos - Editors and Converters. However, no Byzanz icon is appearing within my Gnome Applications list, nor does Search locate it. (I also installed Handbrake, and I do see the Handbrake icon and that application opens normally.)

Since I am using Gnome, I've tried the Ctrl+Alt+Shift+R combination to start the Gnome Screen Recorder, however that isn't happening: no red circle is displayed in the top right corner of the screen, and no screen recording file is created.

Hardware is a Dell E6430 64-bit laptop, 5.15.46-desktop-1.mga8, and--

Code: Select all

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108GLM [NVS 5200M] (rev a1)


Fortunately, I am under no time pressure to figure this out. Why don't I see a Byzanz desktop icon? Why doesn't Gnome Shell Screen Recorder work? How does one persuade VLC to record something that would be useful? Suggestions will be appreciated!

For Byzanz:

I've tried installing Byzanz, and Mageia Control Center indicates that Byzanz is now installed in Videos - Editors and Converters. However, no Byzanz icon is appearing within my Gnome Applications list, nor does Search locate it.

Videos - Editors and Converters is only the MCC category for such programs. Byzanz has no entry in applications list as it is a command line tool. Command line tools have no desktop icon or application menu entry. The program is located under and can be opened via terminal with:

Code: Select all

/usr/bin/byzanz-playback
/usr/bin/byzanz-record

For VLC:
This works fine here to capture a whole screen with different windows/programs open. Issue following command in a console (it will create a flv video in your home directory. You can change it also to .mp4 as in my second command):

Code: Select all

vlc screen:// --screen-fps 25 --nooverlay --sout "#transcode{vcodec=h264,vb=2048,scale=0.5,acodec=mp3,ab=128,channels=2}:duplicate{dst=std{access=file,mux=mp4,dst=screencast.flv}}"

Code: Select all

vlc screen:// --screen-fps 25 --nooverlay --sout "#transcode{vcodec=h264,vb=2048,scale=0.5,acodec=mp3,ab=128,channels=2}:duplicate{dst=std{access=file,mux=mp4,dst=screencast.mp4}}"

I have used simplescreenrecorder, which we have packaged.

I installed SimpleScreenRecorder. Next I figured out to select GNOME on Xorg upon logging in, as on my laptop, Wayland seems to have been the default setting and that was preventing operation. SimpleScreenRecorder combined with GNOME on Xorg works great. Problem is resolved, thank you for the responses.
