I have a docker container which when run opens a URL using firefox which is
the input and stream it to an RTMP URL using FFMPEG FLV. here is the
Github project if anyone wants to test. Nice application.

timecode? not sure.
ffmpeg \

-s ${SCREEN_RESOLUTION} \
-r ${VIDEO_FRAMERATE} \
-draw_mouse 0 \
-f x11grab \
-i ${DISPLAY} \
