This is a simple screen recorder
http://www.murga-linux.com/puppy/viewto ... 087#502087

There is a front end which I wrote and my
programming buddy 'Shadow' created this part
which increments the saving of video mpg's . . .

Code: Select all

#!/bin/sh
X=1
fname="video$X.mpg"
while ([ -f $fname ])
do
  ((X++))
  fname="video$X.mpg" 
done
var="$(xrandr | grep '*')"
IFS=" "
set -- $var
ffmpeg -f x11grab -s $1 -r 25 -i :0.0 -sameq $fname

but how to add sound recording?
would 'wavrec' do it (and then stitch them together) or some
parameter in 'ffmpeg'?

Lob, have you forgotten Fatdog64 has this screen recorder for a while already (menu Graphic --> Screencaster).
ffmpeg can do it, just add the following parameters to ffmpeg:

Code: Select all

-f alsa -ac $AUDIO_CHANNEL -ar $AUDIO_SAMPLERATE -i $AUDIO_DEVICE -acodec $AUDIO_CODEC -ab $AUDIO_BITRATE

For more details, you can check the source.

AUDIO_CHANNEL is number of audio channel, usually is 2
AUDIO_SAMPLERATE - obviously it's the sample rate (44100, 22050, 8000, or others)
AUDIO_DEVICE is usually hw:0,0
AUDIO_CODEC is the codec, you can use libmp3lame, libfaac, pcm_s8 or others
AUDIO_BITRATE is the bitrate reserved for audio, 8000, 16000, 64000, whatever.

Good luck.

Yes I forgot

thanks for the reminder . . .
OK off to look for my head which was loosely screwed
to my head last time I looked . . .

If I find my head, it will make use of the code - thanks again

Bravo Lobster, nothing to say : a usefull little too, like i like them.
If I install ffmpeg from w5, i loose the sound. I withdraw it.
It's very OK !
