description 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.
