I want to use my raspberry pi 3 for a youtube stream via an usb camera. Therefore, I compiled and installed the following tools:

ffmpeg, libx264, libav-tools

However, when running the following code i always get an error that the libx264 encoder is unknown:

ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video0 
-codec:v libx264 -b:v 700k -maxrate 700k -bufsize 700k -an -f 
flv rtmp://a.rtmp.youtube.com/live2/MYYOUTUBECODE

I installed x264 via clone and make install using this guideline. How can I check if this encoder was installed correctly? I am already stuck for 2 days on this problem - please help!

Related hints (e.g. libavcodec-extra codec, type errors) regarding this problem unfortunately also didn't help further.

Thank You.

The entire console output is:

You compiled ffmpeg with no additional configuration options. Encoding with x264 requires libx264-dev as a dependency and adding --enable-gpl and --enable-libx264 configuration options.
