Abstract: Aspects of the technology described herein are directed towards systems, methods, and computer storage media for, among other things, converting a video stream being transmitted in a first streaming protocol to a second streaming protocol without transcoding the content communicated in the video stream. For example, the technology described herein may convert an RTP video stream to a non-RTP video stream without transcoding. The technology described herein extracts a plurality of media content from an RTP package and repackages the extracted content into a non-RTP streaming protocol, such as WebRTC or HLS. Moreover, the technology described herein can provide for the synchronization of video and audio data during conversion.
