Implementations provide low-latency live-video streams using existing content delivery networks. An example method includes receiving a video broadcast as a series of frames and determining, for each frame, whether the frame is a break frame. Responsive to determining that the frame is a break frame, the method includes removing an in-progress tag from a current segment file in a playlist for the video broadcast. The playlist includes at least a previous segment file, the current segment file, and a next segment file, which also has a respective in-progress tag. The method also includes associating the frame with a next segment file in a playlist and transmitting the playlist to a cache server. Responsive to determining the frame in the series of frames is not a break frame, the method includes associating the frame with the current segment file. The frame is transmitted to the cache server as a chunk.

Methods and systems for a content server to select sets of video streams having different encoding parameters for transmitting the sets of video streams to a media device are disclosed herein. In some embodiments, a method for transmitting video streams for a media program from a server to a media device includes: selecting, by the server, first encoding parameters including a first bitrate for a first set of video streams for the media program based on a first estimated bandwidth capacity for a network linking the server and the media device, transmitting the first set of video streams from the server to the media device, determining, by the server, second encoding parameters including a second bitrate for a second set of video streams for the media program, and transmitting the second set of video streams from the server to the media device.

A method and respective system for determining quality of experience parameters of an encrypted video stream received at a client device is provided. The method comprises extracting, from one or more encrypted video streams sent over a network from a content server to a plurality of client devices, a first instance of at least one stream-related feature. A first instance of at least one quality-related label of a plurality of quality-related labels is determined based on applying a trained classifier to the first instance of the at least one stream-related feature, wherein each of the plurality of quality-related labels corresponds to a respective experience parameter of the quality of experience parameters of the encrypted video stream received at the client device.

Systems and methods for bandwidth-limited video transport are configured to receive (or otherwise discern) a selection of video parameter limits that correspond to a bandwidth limit and apply the video parameter limits to an input video stream to enforce the bandwidth limit while preserving video quality. Methods may include adjusting the video stream one parameter at a time until the adjusted video stream meets the bandwidth limit. Parameters to be adjusted may include image resolution, frame rate, image compression, color depth, bits per pixel, and/or color encoding. In some embodiments, the image resolution is reduced first, the frame rate is reduced next, and the image compression is increased last. The extent and/or order of the adjustments of the parameters may be selected by the user, based on the content of the video stream, and/or based on the bandwidth limit.
