I'm trying to grab content from http://tv.nrk.no and the content is downloaded as *.flv. But VLC cannot play that file, no errors or other information.

I have tried to reinstall ffmpeg with additional codes: brew reinstall ffmpeg --with-libvpx and convert the flv file to mp4. But getting error *.flv: could not find codec parameters.

So how can I either download in another format? Or convert the file to mkv/mp4?

Please use the [homebrew] tag instead of [brew], which has nothing to do with that. I edited your question to fix the tag. Thanks! – bfontaine

I cannot download the content, so I can't try the input video from http://tv.nrk.no

And, what is your command line? Can you post it? It seems that you don't have some codec.

Maybe you can download ffmpeg-static to transcode the video.
