Cannot record from webcam

I have done a new installation of dolphin 7.0.1 and am unable to record, using the webcam.

Below is the cronlog:

I have the same problem on new installation of dolphin 7.0.1. Maybe someone know how we can fix this? :)

OK, so first question.. Did it work before 7.0.1. Second question.. Did you upgrade to 7.0.1 or is this a fresh install?

At the risk of being flamed for asking another video question - I am having a very similar issue to Denre.

I have searched the forum, and can only find this relevant post where ffmpeg is failing in such a manner.

I assume the first call to ffmpeg is to generate the thumbnail - which is working, it's just generating the mp4 that seems to be a bit of an issue.

It looks like it might be failing because there is no audio present in the stream at all? Given that there are zero audio channels in the input stream.

Any light that can be shed on this would be much appreciated..

It appears that ffmpeg needs the devel libraries installed to be able to work.

On "yum" enabled systems, the quickest and easiest way to do this is by installing ffmpeg-devel and all it's dependencies.

eg

user@server # sudo yum install ffmpeg-devel ffmpeg-libpostproc

Has fixed my problem up :-D

I am having the same problem. I have a fresh install of 7.0.1. I have done a yum update and also the yum install ffmpeg-devel ffmpeg-libpostproc

that installed a couple of things on my server. I have rebooted the server, restarted the apache, re'yum updated

and I still get

How can this be fixed?

Have you foind the solution for this ? I'm still trying to resolve it! Got all the ffmpeg-devel and all installed on my Centos server still not working :-(
