Channel Analytics message: "rebuffers per streaming hour have exceeded our quality threshold."
Rebuffers are typically due to the device not getting data fast enough - with HLS the data in the playlist needs to be available in time for your device to retrieve it.
Be sure your CDN supports range requests.
Rebuffering can also occur when HLS is not properly encoded - there should be a Keyframe, and SPS/PPS pointers at the start of each segment. For each video you should have multiple bitrate versions, all aligned on segment boundaries, so that the device can switch to a lower bitrates stream when the bandwidth fluctuates, and up to a higher bitrate when available. Each link in your metadata should point to a master playlist that contains links to playlists for each stream variant.
This should reduce rebuffering by allowing the device to reduce video quality slightly if available bandwidth fluctuates.
- What is the rebuffers per streaming hour threshold?
- Our rebuffering threshold is one rebuffer per hour. If you are seeing this message and your rebuffers are below the threshold, you can create a ticket with Partner Success.
