ffmpeg2theora not encoding from v4l device


Hello all ,

I'm using slackware on a 64-bit system, and I have a video capture device installed in my system which normally works fine. Both mencoder and xawtv work fine, and I'm able to watch and record TV (e.g. using mencoder) without any problems.

However I would like to try to encode from a v4l device directly into ogg/theora format. I found a program called "ffmpeg2theora" which is avaliable here;

http://www.v2v.cc/~j/ffmpeg2theora/index.html

and this program can support input from a v4l device. However, I've hit apon a problem. If I try the following;

Code:
./ffmpeg2theora-0.17.linux.bin  --v4l /dev/video0 -o test.ogg
I get this error message;
File `' does not exist or has an unknown data format.

/dev/video0 definately exists, and can be viewed with xawtv and mencoder. I'm not sure what the "`'" means, however. Normally I also have to specify an input too on xawtv and mencoder (the input is via an svhs input, in xawtv and mencoder there's usually an option to specify weather the input is from video or svhs, e.g. mencoder -tv input=1 ) .

I can't find such an option in ffmpeg2theora as well as getting the strange "File `' does not exist" message.

Can anyone help out? Thanks

SP
