Operations include extracting and presenting data associated with a media stream being transmitted from a source device to a target device. The media stream may include a stream of video frames displayed by the source device. A screen sharing application, executing on the source device, may capture the stream of video frames. The screen sharing application may transmit the stream of video frames to a target application executing on a target device. The target device (or an intermediate device) analyzes the media stream, as the media stream is received from the source device. The target device may execute pattern matching to extract information, including text, images, and audio clips from the media stream. The target device may present the extracted information or use the extracted information to perform tasks, such as filling in a form.
