Abstract
In some embodiments, a method receives playback information for a plurality of representations based on one or more videos being played at a media player. The plurality of representations have at least one different characteristic that affects playback of the video. A dropped-frame measurement is predicted for the plurality of representations based on the playback information. Then, the dropped-frame measurement is compared to a threshold for the plurality of representations. The method marks a first set of the plurality of representations as not being available based on the comparing. A second set of the plurality of representations are provided to the media player when the media player requests a video for playback and the first set of the plurality of representations for the video are blocked from being requested by the media player.
