Technologies for end of frame marking and detection in streaming digital media content include a source computing device communicatively coupled to a destination computing device. The source computing device is configured to encode a frame of digital media content and insert an end of frame marker into a transport stream header of a network packet that includes an encoded payload corresponding to a chunk of data of the frame of digital media content. The destination computing device is configured to de-packetize received network packets and parse the transport stream headers of the received network packets to determine whether the network packet corresponds to an end of frame of the frame of digital media content. The destination computing device is further configured to transmit the encoded payloads of the received network packets to a decoder in response to a determination that the end of frame network packet has been received. Other embodiments are described and claimed.
