x264, raspberry

Is the raspberry hardware encoding supported from x264? Have you got an example on how I can use it?

By "raspberry" do you mean the Raspberry Pi? It should be supported. It is just an ARM processor, isn't it? If it doesn't have NEON instructions it is probably useless though.

I believe they were asking if x264 would use the H.264 encoder that is in the Pi's SoC. Which would obviously be: no.

Yes. You're right.
I have written an video surveillance application that runs in a Debian system with x264 (using FFmpeg). In Raspberry PI the program works but I can encode only 2 frames for second.
If the x264 library will support the hardware encoding of Raspberry PI, my application can be usable. Is possible?
If not I have to study and implement the hardware encoding directly without x264 and FFmpeg.

x264 can't "support" a hardware encoder; x264 already is an encoder. Using a different encoder (the hardware encoder) by definition means not using x264, because it's a different encoder.
