Ugh while its nice netrunner rolling comes with vokoscreen for bizarre reason it wont work as soon as I attempt to use it, why?

sudo pacman -S gst-plugins-ugly gst-libav gstreamer0.10-ffmpeg

3

nope, that did nothing.

I have installed kazam and that works fine, just sucks that the installed screen recorder doesnt work for me for some reason.

4

Vokoscreen uses libav or ffmpeg directly.
Would be interesting to see the error output of vokoscreen when run from the terminal. (Please use quote or code tags to paste that terminal output here in the forum)

5

@leszek, This person already posted the output from the terminal.

6

Upps, somehow my mobile phone did not show that command output. Strange.
What would be interesting is the output of this command

This should throw an error which might help debugging this problem.

@TheMadOne
First, try it without the usb Yeti Stereo Microphone connected.

I just ran vokoscreen and it is working fine on my machine, I’m not getting a crash, it’s recording fine.

Here is my output:

nope still a no go, wonder whats happening here.
in any case will probably just be rid of vokoscreen now that kazaam seems to work fine.
Keep this thread in reference though

9

I think I see the issue remove mplayer and smplayer, I remember reading a while ago that vokoskreen sometimes has issues with mplayer…

10

No that changed nothing, vokoscreen is simply broken on my system.

11

I am still waiting for the ffmpeg command output (see my last comment). This might give us a clue what’s going wrong.

Hmm… so that command seems to work. Please check if the /tmp/vokoscreen-*.mkv file recorded your desktop.
If it worked its not a ffmpeg issue but a vokoscreen gui issue somehow.

14

No I only have a video in /tmp/

15

Does that mean the above ffmpeg command recorded a video successfully or not.
From the output I see it recorded something.

16

My output looks very similar to yours so I can’t tell where it is failing on you. Does the GUI disepair on you or is it that you just can’t find the files it created? By default vokoscreen saves it’s videos under /home/{user_name}/Videos.

Could you post your graphics chip and whether or not your using the free (opensource) or non-free (proprietary) drivers? All of my systems are Intel only so this may be why I’m not getting the issue.

17

I am using the opensource driver, I know where vokoscreen usually puts its files but it doesnt record a split second of video.
It just stops.

I am using a old ATI HD4200 card here which by now doesnt have prorpietary drivers in linux anymore.
I have to use the open source driver

18

Have you tried installing the Vokoscreen 2.0.0-1 version from the AUR?

yaourt -S vokoscreen

I’m thinking that this might just be some kind of unique compatibility bug with the 1.9.0-1 version from the blueshell repository, maybe something to do with it being compiled against older libraries, or something similar.

19

As vokoscreen is usually only compiled against qt4 and not against libav or something (it just uses avconc or ffmpeg command directly) I can only imaging it failing because of the ffmpeg output being different then expected. Vokoscreen tries to scan the output of the command to interactively show the framerate when recording.

20

Yes, but couldn’t some of the changes to the latest ffmpeg update be changing the output just enough that the older version of vokoscreen doesn’t understand them.

Here is the ffmpeg release notes for version 2.3.3
http://git.videolan.org/?p=ffmpeg.git;a=blob;f=RELEASE_NOTES;hb=489d066

The next update pack will include ffmpeg 2.4.1, here is those release notes:
http://git.videolan.org/?p=ffmpeg.git;a=blob;f=RELEASE_NOTES;hb=release/2.4

There is also ffmpeg-compat in the repositories that provides an older ffmpeg version.
