Description:

NOTE: As of today (19. August 2013) Artur Lacki (Lacky) have taken over development and mangement of this project. He has decided to use Bitbucket instead of Github. So for more information and latest sourcecode please visit: [url] https://bitbucket.org/Lacky/fdesktoprecorder/ [/url]

FDesktopRecorder is a program that can video record a single window or your entire desktop using FFmpeg.

This can be handy for:
* "How-to's"
* Product demoes
* in-game videoes
* Educational videoes
* Recording Interactive whiteboards like "SMART Boards"
* etc.

Basic features:
* Video record a single window
* Video record your entire desktop
* Video record a region of your desktop

Based on a script by Peter Lyberth from the danish GNU/Linux show "Kanal Tux" http://www.kanaltux.dk

Please note: This is a early version of the program :-)

Requires:
https://github.com/froksen/FDesktopRecorder#requires-to-run

"Nice-to-know-stuff":
* Configurationfile: ~/.config/fdesktoprecorder/fdesktoprecorder.conf
* If you experience weird failues try removing the configurationfile and relaunch the program.

application name is really really not friendly. To be honest, it is even hard to pronounce application name.

Thanks.. Yeah I know that it isn't the best name in history. ;-)

But when I began the project it was more to learn Qt/C++ than creating the actual project (The project was stated about 1,5 month ago but was only on danish). Although as time passed the program better (IMO), so now I have translated it to english, and yeah the name has stuck but maybe I'll change it some day :D

Any suggestions? ;-)

If you made more great applications, letter F can be your signature ;).

Hi

When kalac made his comment the program was called "ktffmpegQt", I later renamed it to FDesktopRecoder :-)

But nice to hear that the name and description makes sence :-D

Why the F at the beginning and not simply DesktopRecorder ?

Hi juancho

Its very typical/normal to have these kind of start letters. Like "KSnapshot", KMess and so on.

In this case the "F" is for "Froksen" :-)

Hi jboss1995

As far as I can see it is a problem with the resolution or simular and as far as I have been able to "google arround" it is a problem with ffmpeg it self.

I'll look for a fix for this, but currently I have been unable. If you or anybody knows how to fix this issue, please let me know :-)

But thanks for letting me know of this issue.. :-)

>>> w:1680 h:1015
!!! Your Aspect Ratio is not valid !!!
For Example:
width = ( ( width % 2 ) != 0 ) ? ( width + 1 ) )
height = ( ( width % 2 ) != 0 ) ? ( width + 1 ) )
will done w:1680 h:1016

Sorry Example failure ;)
again:
>>> w:1680 h:1015
w = ( ( w % 2 ) != 0 ) ? ( w + 1 ) )
h = ( ( h % 2 ) != 0 ) ? ( h + 1 ) )
will done w:1680 h:1016

Hi

Thanks for the tip, always nice :-) Yeah I know that some aspects/radios are invalid, although I should have made a function that takes care of that, but it is not as pretty as yours - so thanks again for the nice tip :-)

I have been looking at your sourcecode before and found some tips and tricks there as well :-) So thanks for making qX11grap - it looks great too :-)

I'm still rather new to Qt/C++ so it tips and tricks are always welcome :-)

Hi

Yeah, i'll make a "readme" soon, sry...

Currently there is no *.deb package, but you can compile it from source via qmake.

Make sure that you have deps installed and qmake/qt-libs + KDElibs/KDE-devels. (dont what they are called in Kubuntu)

After that. Download the sourcepackage, and extract the content. Within the folder do:

qmake FDesktopRecorder.pro
make

now you should have a binary file, or if not an error output that can help you further.. :-)

Hope it helps :-)

Hi

As default ffmpeg tries to autodetect the videocodec.

For better quality you have to go Edit=>Settings=>In the "Record settings tab", remove the check-mark from "Auto-detect" next to "Video codec".
Make sure that video codec is set to libx264 => Press OK and you should be good to go :-)
