(old)Puppy Linux Discussion Forum

Hi All

If you want to make videos in Puppy Linux to upload to youtube etc, then just open your terminal and bash the following code in.

#!/bin/sh
var="$(xrandr | grep '*')"
IFS=" "
set -- $var
ffmpeg -f alsa -ac 2 -i hw:0,0 -f x11grab -s $1 -r 25 -i :0.0 -sameq /root/test.avi

FFMPEG will now record your desktop and your Mic + Sound input as well, just use CTRL+C to end the recording.

This will give you a big file of nice quality, I would suggest you use FFConvert to shrink it down to a few megs so you can upload it quicker to youtube.

This means you dont need to install apps like xvdcap or recordmydesktop as you can do it straight from FFMPEG.

Cool! I downloaded "Recordmydesktop" after watching one of your videos "Puppy Linux 5.28 Part 1 & Pt2" (Yesterday.) I will try this, thanks...

I tried it, very nice. But I can not view the videos from Puppy, but I can from a different puppy build and my main OS. It does the same for "record my desktop" I am using 5.2.8 004

Hi Buddy

I dont use the updates and I have no problems I am using 5.28 with no update added, and mplayer plays the original files back no problems at all.

I will add the 004 update and let you know. Thanks for your kind words re me youtube.

Hi I have upgraded my 5.28 to 004 and my mplayer works just fine so please can you post some screen shots of your issue and I will try to help you resolve it.

Thank you for the reply..

Here is a quick video.

I have decided to re do my USB, I was hoping to know what went wrong but no big deal.

Thank you

Edit:

It works fine now.

I'm excited !

the ffmpeg line runs good on puppy 511 which had ffmpeg 0.5.2 installed without x11grab support .

i have compiled 7.11 and 9.1 with x11grab and can see the screen capture in mplayer . gxine-059 does not want to play .avi videos , but thats it .

will have to check it on Puppy 4 series where i could not get it to work until now .

So...it seems to be dependent of the selected screen resolution.

That works for me with ffmpeg-0.9.1 also. It produces good video quality due to libx264. Of course you need that lib to be installed...and that your ffmpeg has been compiled supporting it.

The commandline has to work , otherwise i get crazy error messages like
#Unable to find a suitable output format for '-f'

Screen resolution not being larger than actual is important as pemasu states .

The configure script autodetects headers in /usr/include .

If no alsa headers , no alsa !

I had the same with BSD kernel headers installed .
/usr/include/dev from it gave

/usr/include/dev/bktr/ioctl_meteor.h:185: error: expected specifier-qualifier-list before 'caddr_t'

which i could not solve .
renaming /usr/include/dev to /usr/include/dev.ffmpeg.backup
AND running ./configure $MYPARAMETERS again
did not find /usr/include/dev/ and now ffmpeg finally compiled .

The sound headers should be in /usr/include/alsa .
alsactl -v
alsactl version 1.0.20

would roughly correct show which alsa lib version is installed .

By getting /usr/include/dev out of the way i got ffmpeg to compile on 4.3 and x11grab working .
Also gxine-059 shows the avi format .

*****
./configure should show these parameters at the very end : I can't find a ./configure parameter to force alsa ie --enable-indev=alsa .

funny thing is ffmpeg recognizes the output format because of the outputfile.extension .
works for me to create a flash file .

gxine renders it 45degrees deformed .

FlashVideo File is approx. 50% larger in size than AudioVideoInterleave File .

Hmmm . the codeline does not work for me in a script ... ffmpeg seems not to like ' ' spaces but tabs :

This test script works for me , i have also set filetype none in geany

Is there a way to set up a short delay?

OR

Hi All

This is my final entry after trying many variations out.

#!/bin/sh
var="$(xrandr | grep '*')"
IFS=" "
set -- $var
ffmpeg -f alsa -ac 2 -i hw:0,0 -f x11grab -s $1 -r 30 -i :0.0 -sameq /root/test.avi

I have found 30 frames to be the optimal and it produces the best visual quality, I have tested this on Puppies 5.25/5.28 & 5.31 Slacko, I have now moved to Slacko as my main operating system as I just love it to bits.

I hope all of you trying to get this to work with older Puppies are successful please contact me if I can help you in any way.

MORE frames = MORE MB

I had forgotten that it ran for 40 minutes and the avi file became 1,15GB ( -s 1280x1024 -r 25 )

No luck with mp4 format either , still very very large .
Would be nice to get more extensions to work andor to decrease the filesize .

Could not get 9.1 compile on one Puppy431 installation but 7.11 and 8.10 compiled .

yasm >=0.8 needed to enable yasm and the source compiled fine but it seems not to have any effect .

Despite --enable-x11grab some other configure options disable it
and the binary does not include x11grab though ffmpeg -help says so .
The first time i compiled source i had to look into the /tmp/* folders for hints .
After installing several header and library packages it worked .
