grabbing videos from youtube

There are lots of full length movies ( on youtube . You cannot grab that video as it is drm encrypted . So I decided to use ffmpeg
I took a screenshot of web browser (opera) then opened jpg file in kolourpaint to find out top left & bottom right of video frame in browser . They were found out to be
24,129 & 669,524
which indicated 645x395 video dimension
So , I ran
ffmpeg -f x11grab -s 646x396  -r 30 -i :0.0+24,129 -sameq out.mpg
comment : Actually ffmpeg said 'Frame size must be a multiple of 2'
& switched to browser where video is being streamed.

Voila , I have replica of video on youtube .
File size is big though , 22 seconds of 4.6MB .
I will rip it using

Only drawback is
If your internet speed is slow then there will be moments of still video being buffered which you have to clip while transcoding .

If you have proper connection speed then play video in browser for desired duration & relax.

Tell me if you find this useful .

I am awed by ffmpeg's x11grab functionality because of its lossless encoding (forget file size).
I think , this is bypassing DRM method a.k.a .

Thank You.
