why is streaming to an flv server with ffmpeg only showing black/blank video for clients?

When I stream to an flv server, like flash media server, using ffmpeg, like

 ffmpeg -i input -vcodec libx264 rtmp://hostname/streamname

it turns out black. Why is that?

Turns out that in "more recent" versions of ffmpeg, the default x264 pixel format is "yuv422p" which isn't supported by most commercial encoders.

Fix: specify -pix_fmt yuv420p or -pix_fmt yuyv422 for the x264 format.
