Not negotiate means there is something incompatible at run-time. I have
two suggestion for you to look at:
1. You camera maybe not support 640x480 ?
2. Or maybe your camera is jpeg only, and requires jpegdec afterward ?
Let use know if on of these two was your issue. Meanwhile, you should
consider a tune= parameter on x264enc, the default is not that great
for streaming (very high CPU and latency).
