Hello, This is not really a BBB issue so you might not find the support you need.
from what I can tell you only have a warning and it can be ignored. you are have the output set to a file out.avi. Does it exist? maybe check the ffmpeg site for help. I use mplayer instead .... so if you want you could try ... sudo apt-get update sudo apt-get install mplayer sudo apt-get install v4l-utils mplayer tv:// -tv driver=v4l2:width=960:height=720:device=/dev/video0:outfmt=MJPG reference => here <https://www.blogger.com/blogger.g?blogID=4064111232456282252#editor/target=post;postID=3975722784958133717;onPublishedMenu=allposts;onClosedMenu=allposts;postNum=24;src=link> good luck On Monday, 26 January 2015 19:59:55 UTC+1, Felipe ordoñez wrote: > > > Hi everybody, > > I am new with beaglebone and I am trying to connect a webcam to do image > processing. > I do all the steps of the Derek malloy's website( > http://derekmolloy.ie/building-ffmpeg-for-beaglebone-from-source/#comment-29934) > > > > there is not something wrong in the process. > > But when I finished all the process I type: > root@beaglebone:~# ffmpeg -f video4linux2 -i /dev/video0 out.avi > > and appears: > > WARNING: gnome-keyring:: couldn't connect to: > /run/user/daniel/keyring-37jbja/pkcs11: No such file or directory > ffmpeg version 0.8.16-6:0.8.16-1, Copyright (c) 2000-2014 the Libav > developers > built on Sep 17 2014 13:57:48 with gcc 4.6.3 > The ffmpeg program is only provided for script compatibility and will be > removed > in a future release.
