Hey all,
I am running Kdenlive 0.7 beta on Ubuntu 8.10 beta. The software looks really promising. Question: I read that 0.7 supports screen movies. I have looked on the site and in the product and cannot figure out how to do it. Any ideas?
Thanks,
Ben
Screen movies? What do you mean by that?
Basically you just have to do as it says: add --enable-x11grab to ffmpeg configure line.
When you run your Kdenlive, you click on "Capture monitor", then select "Screen grab" from the drop down menu, then click the record button, and follow the instructions.
There is a page in the settings, where you can set some options for screen capture.
Note, that if you used the wizard to compile Kdenlive, there are currently no way to enable screen grab. I have a new version of the Wizard ready, but is waiting for jb to implement some minor changes in Kdenlive before I want to release it.
I noticed yesterday that although I am able to select screeb grab in the capture monitor (as described also above), upon pressing the record button nothing is really captured.
I used the Builder Wizard indeed.
I wondered if I missed some dependency or so, but apparently it has to do with the Builder Wizard, or do I understand that wrong?

What I do:
- Press the record button.
- After a short while, a message appears telling me to mark a region
- I mark a region
- I press Enter
- Recording starts (message is show in the monitor)
- After a while, I press the record button to stop recording
- The clip shows up in the projectree.
Could you perhaps try the new version of the Wizard I have just uploaded? There was an issue with the wizard _not_ updating the settings for MLT in Kdenlive - perhaps this is related.
Thanks,
Mads
I downloaded KBW 0.6.0 (previous install here was by sue of the 0.5.0). I checked the screen-grab function again and no luck: it still does not want to capture a thing whether trying to capture whole screen or a selection upon record and/or Enter (for selection) the screen remains excatly as before pushing the record button, nothing happens.
In the settings I have not changed a thing, thus:
I have not selected audio captrue.
video capture params
-f x11grab -r 15 -s %size -i :0.0%offset
and
encoding parameters:
-vcodec mpeg4
file extension:
avi
Could it be I am missing a dependency for the encoding or capturing?
I can not get it to work unfortunately, I do like this new option of course (once it works)
=================
Could it be that by installing with KBW the bold marked part is perhaps missing (from the compilation instructions) upon compiling/installinf FFMPEG?:
If you want to compile FFmpeg by yourself:
Get source code:
svn checkout
svn://svn.mplayerhq.hu/ffmpeg/trunk/ffmpeg
Recommended compilation flags:
./configure --enable-gpl --enable-shared --enable-pthreads --enable-libmp3lame --enable-libfaac --enable-libfaad --enable-libvorbis --enable-swscale
If you want to enable screen capture in Kdenlive, also add the following flag:
--enable-x11grab
==================================
Update:
Did a new install from the FFmpeg folder with:
./configure --enable-gpl --enable-shared --enable-pthreads --enable-libmp3lame --enable-libfaac --enable-libfaad --enable-libvorbis --enable-swscale --enable-x11grab
This did not help me any further.
The only thing that DOES happen is when i turn audio capture ON, I get an captrue crashed error. By unselecting audio capture as said before nothing happens...
Perhaps I should recompile kdenlive as well after recompiling FFmpeg?
Thus I decided to run the KBW 0.6.0 again and then noticed (!) that upon pressing the " advanced" button the enable x11 grab support feature was by default unchecked!
(this is the same screen as where you can check "append date" and " install as root" underneath this there is the advanced button).
Thus I guess/hope that the problem was that by running the current wizard FFmpeg is not configured for x11 grab support by default.
@Mads: Perhaps this option (hidden under the advanced button) should be selected / marked on by default?
Now that I try to compile and install again via KBW and the x11grab support enabeld I get:
The operation was a failure.
This error was returned:'FAILURE Some kind of error occured: Unable to build ffmpeg'.
This is because it can only be done as root.
However when I try to use the option Install as root I get right at the beginning of the wizard this error message:
This error was returned:'FAILURE Some kind of error occured: Some kind of error occured while calling /usr/kde/3.5/bin/kdesu. Unable to proceed'.
To summarize I encountered two problems:
1) x11 grab support is not enabled by default
2) option 1) fails for apparently kdesu or kdesudo can not be called properly (is it possible to use su and sudo in the wizard instead of kdesu and kdesudo?), in the folder /usr/kde/3.5/bin/ however kdesu is present, so I do not know whether trying to install as root fails, one should expect a pop-up window demanding you for your root password.

Hi again
Yes, sorry, you are probably right about the x11grab and enabled by default. My bad. Apologies, should have mentioned it, things went a little fast there. Will enable by default in next version.
Could I ask you to email me the log from the run, where you failed to install? Also, what distro/version are you running? And, what version of KDE are you _running_, and what version are you trying to compile against? (if you are running kde3, kde-config should tell, otherwise kde4-config).
Also, could you try to run the wizard without installing as root, and trying to install into /tmp/kdenlive (The page titled "Compile options", just write /tmp/kdenlive in the Install dir. Then test that install. If it works, we will take it from there!
Thanks in advance.
Hi,

b) do this for me in a terminal and paste the output:

Hi again.
Ignore option a) in my previous post - we have crossed eachother.
I think this error may occur, because you have some files owned by root in your source folder? Could that be? Perhaps ffmpeg is so organized, that files get copied during the "make install" step, to the source dir, by the current id, that could explain it.
Perhaps you could try to provide a completely clean directory for the sources, that is, use e.g. /tmp for the sources too. That would mean some time spent downloading the source files, but at least we could make sure that root ownership issues was not an issue.

Ok, thanks. Your version of kdesudo - which I really suspect is kdesu - does not support the --comment option. I will make a new version of the wizard that checks for --comment in the help output.
I may be done with this in 15 minutes, and will upload a "special" version, which I would really like for you to try.
OK I will await the special version and then start that one including new downloads in a new folder and give it another try.
I appreciate the time you spend helping me, but I guess somehow I am helping you to optimise the wizard as well :D
PS what I would like to emphasise that as mentioned I did succeed to install Kdenlive 0.7.0 by use of the Wizard 0.6.0 but ONLY as non-root (problem 1) and that both as root or non-root I get error messages when I try to install with x11grab support enabled (problem 2)(in disabled mode I apparently somehow succeede in installing). In other words I managed a non-root installation but without screengrab support.
Will try one more time without the append date setting marked.

Would be great to know what it says from completely pristine dirs. I have no real idea what --enable-x11grab requires - I just googled a bit, and it seems there may be some more magic one has to do in some cases.
Anyway, please find attached a "special" version of the wizard, that tests for --comment to kdesudo. I would very much appreciate the log from a run into empty directories with this version - with or without installing as root.

P.S. You are right about me optimizing the wizard! But, thats the real purpose of it - to collect the knowledge required to succesfully compile Kdenlive into a program that can actually do it for you. Which again should enable people that do not read g++ manuals for bedtime to actually get a working Kdenlive installation :-)
trying now as non-root with source dir /tmp with no previous source files present in it and option download, compile and install
(which may take a while...)
problem 1 is (of course) solved: x11grab support is now marked enabled by defaultin the wizard
pop ups says:
The operation was a success.
To start Kdenlive, run the following command in a console:
/home/michiel/kdenlive2/20081016//bin/kdenlive_start
Remember: At any time you can always re-run this Wizard. It will remember your choices, so you can quickly run it to update your sources or installation.
What do you want to do now: Close the wizard, view the log from the build process or continue? (Cancel this dialog)
:D :D :D
I will try if I can open the freshly installed kedenlive and whether screen grab functions or not.
and yes screen grab does the " capturing..." now as it should
(unfortunately attachments extension AVI is not allowed here in the forum, otherwise I would have attached my sample screen grab AVI)
:D :D :D
That leaves only the install as root problems I had but those are not really relevant for me then now that all installs fine.

Remember that /tmp is typically deleted when you reboot your system.
And also, x11grab is now enabled, because the wizard remembers your choices. So its not because I changed anything. (Because I didn't :-) )

Sounds good!
Re the root install: It would be nice to know if it works, but I am pretty confident it will work. So, thanks for helping improve the Wizard - for the benefit of others :-)
I think the term used on the site is screen grab:
http://www.kdenlive.org/node/2
* Firewire capture: DV and HDV
* Video4Linux capture: support for webcams (requires ffmpeg)
* Screen grab: grab your desktop or a region of it with sound (ffmpeg compiled with "--enable-x11grab" required)
I have been looking for a usable open source product that runs on Ubuntu that lets me do two things I currently do with Camtasia Studio 5.0 on Windows:
Thanks a bunch. The new release and the drupal site look great.
