What does com.apple.coremedia.videoencoder do?
VTEncoderXPCService is VideoToolbox’s out-of-process video encoder used by FaceTime, Photos, Final Cut, browsers, and other apps that compress video with Apple’s GPU-accelerated codecs. It starts on demand when an app requests hardware/software encoding. You need it while encoding or streaming video; quitting can stall the active encode (and the call or export using it) until the client relaunches the service.
