A method for providing a media feed to a server. The method includes a client transmitting to the server over a transport layer connection a message comprising a header and a body, wherein the header of the message does not indicate the size of the body of the message. The method also includes the client storing in a transmit buffer media data corresponding to the media feed, wherein an encoding bitrate setting is used to generate the media data. Transmitting the body of the first message to the server over the transport layer connection comprises: 1) before transmitting any media data corresponding to the media feed, the client transmitting to the server over the transport layer connection a movie box comprising information identifying a codec and codec configuration information; 2) after transmitting the movie box, transmitting one or more Common Media Application Format (CMAF) chunks, wherein each CMAF chunk comprises media data corresponding to the media feed; and 3) after transmitting the one or more CMAF chunks, transmitting an end of stream indication, wherein the end of stream indication is i) an end of stream flag or ii) a zero-size chunk.

A system, method, and Head-Mounted Display, HMD, apparatus for recording a video and playing back the video to a viewer in a Virtual Reality, VR, environment. A geographical area is recorded with an omnidirectional video recording camera by dividing the geographical area into a plurality of area portions and recording in separate video sections, each of the area portions while moving the camera in different directions. Time points in each video section are associated with virtual locations of the view. At a time point providing the viewer with a choice of directions to proceed, the system receives the viewer's choice and presents to the viewer, a video section corresponding to the virtual location of the viewer and the desired direction of movement. The viewer's choice may be indicated by detecting a direction of the viewer's field of view or by receiving from the viewer, a response to a banner notification.

A method performed by a client for upstreaming to a server a live media feed is provided. The method includes the client establishing a transport layer connection with the server; transmitting to the server a first message having a header and a body; and storing in a transmit buffer media data corresponding to the live media feed as the media data is generated. The header does not indicate the size of the body. A quality setting is used to generate the media data. Transmitting the body includes:
