[Ffmpeg-devel] URGENT- FFMPEG- Video grab error- Please help

Sat Mar 11 09:02:55 CET 2006

Dear Sir,

 I am having trouble in grabbing video using FFMPEG. I am using the video4linux for this. The webcam i am using is Logitech Quickcam Pro 4000 and it works perfectly fine with xawtv & even with gnomemeeting. The device is also listed in the dev folder as /dev/video0. But still i am getting the error "Could not find video grab device". Can you please help me.

 The audio grab is working fine when i used /dev/dsp. 

 This is what i am using to grab the video. 
 ffmpeg -vd /dev/video0 -y test.mpg

 I am using the latest cvs version which i downloaded last week.

 When i checked this page http://article.gmane.org/gmane.comp.video.ffmpeg.user/2589/match=video+grab, i got an answer to check the below given bold commands. I am mailing the result for u to make things easier.
