RecordMyDesktop- no sound

[PDA1]

I'm running Ubuntu 12.04

In using RecordMyDesktop (RMD), while watching a video online, no sound is recorded.

In the RMD sound Device is set as "default"

aplay -l output is;

**** List of PLAYBACK Hardware Devices ****

card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0

card 0: Intel [HDA Intel], device 1: STAC92xx Digital [STAC92xx Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0


Any idea how to fix this from someone who has actually done it?

Use "pulse" instead of "default".

And then install pavucontrol with:

sudo apt-get install pavucontrol

This mixer gives you then the posibility to change the device from which RMD shall record.

That worked perfectly!

Thanks!

The other problem is that after about 5 seconds into the playback of the record desktop, all motion within the video ends. Playback still continues with the sound playing very well but there's no video movement. (I'm trying to copy an earthcam video feed).

Yeah I know that ...

... click the button for advanced settings. Go to the performance options (don't know the correct words because I'm German → I have the german version) and activate all options instead of the first one, something like "encode while recording" because this will speed up your video and make a for example 5min recording to a 5s video. Furthermore you should create a new folder which you use as "work directory" in the advanced settings.

By the way: You should try Kazam, just search in the software center.

Kazam doesn't work.

It doesn't allow for any kind of select region...even though there's the option of it.

[Halbblutplins]

Normally Kazam shall show a rectangle which you can resize and then you would press enter and click on start ..... do you use normal desktop environment so Unity or other like Lxde? Because on Lxde this function doesn't work.

Kazam works the best for me. It does have a rectangle to select region what you want. The only problem I have is the color is too green and I don't know how to correct the color.

Running 64bit 12.04 with Unity, I have: Kazam Screencaster - "NCC-2893" 1.0.6 version.

I'm running Gnome-Desktop instead of Unity. ('Pretty sure that's what it's called...regardless I'm not using Unity).

'Can't select any region or area. Kazam dialog just sort of goes "gray" and does nothing.

Thanks for trying.

[Halbblutplins]

Using unstable ppa fixes the colour bug:

Open terminal and type in:

sudo apt-get remove kazam

then add the ppa by typing in:

sudo add-apt-repository ppa:and471/kazam-daily-builds

then this one (really important!):

sudo apt-get update

and finish by using this command:

sudo apt-get install kazam

Have fun!

If you can, try on Unity.

If this doesn't help I have an other programm for you:

FFmpeg

It's a commandline tool which is really powerful.

Here's is an example you could try:

ffmpeg -f x11grab -s ****x**** -i :0.0 -r 30 -qscale 1 -vcodec mpeg4 /home/******/video.mp4

I explain ...

- "ffmpeg" → programm;
- "-f x11grab" → just don't change;
- "-s" → Resolution → put instead the * the resolution you want for example "1920x1080";
- "-i"→ just don't change;
- "-r" → framerate;
- "-qscale"→ quality → from 1-30 (30 is bad);
- "-vcodec" video codec; the rest → direcory where to safe → put instead * your username

important!:

If you wanna record only a region use an other syntax for resolution option "-r".
Use instead of "****x****" → " ****x****+'''','''' "

**** → which size the region have
'''' → 1. is X-coordinate and 2. Y-coordinate

-----------------------------------------------------

but before you have to install ffmpeg:

sudo apt-get install libav-tools
