Use a computer encoding software like OBS (free), or vMix/Wirecast (paid). Add in the software a video source (saved image), add an audio source (recorded file or microphone or camera). Configure your YouTube Live output destination. Now you need to select the signal sources. Select your audio/video sources. The mixing software will use the video and audio sources you specify, mix them into a program output, and stream live to YouTube.
