[FFmpeg-user] Directshow Crossbar Support

Hi,

I'm trying to record some live video using an Osprey-230. I can't seem to
get ffmpeg to work at all. After some googling it seems like it might have
to do with the device requiring crossbar support. Is it still the case that
ffmpeg lacks this?

Here is a command that is not working along with the output.

Any help greatly appreciated.
