Abstract:
Disclosed are various embodiments for facilitating uninterrupted playback of video streams using lower quality cached files. A video file corresponding to an entirety of a video content feature encoded at a first quality is obtained. A video stream corresponding to the video content feature encoded at a second quality higher than the first quality is then obtained. The video stream is rendered for playback on a display. In response to detecting an unavailability of the video stream at a particular time in the video content feature, the video file is rendered for playback on the display in place of the video stream and commences at the particular time in the video content feature.
