Hi,
Is there a way to control the polling frequency/interval for HLS variant playlists / MPD manifests with the Bitmovin web player?
At the start of a live event, the manifests only contain a few segments, and it seems that the buffer gets starved quickly. However if the player was refreshing the manifest more frequently, it would find new segments.
I tried varying the segment duration and with shorter ones, the polling frequency increases as well. Is there a way of dissociating both?
I didn’t see anything obvious in the PlayerConfig.
Yes, you can set the polling rate for HLS variant playlists and MPD manifests with the Bitmovin Web Player. The player refreshes the manifest automatically at a rate that is based on the segment duration and the updateInterval declared in the manifest. If you want to set the polling rate independent of the segment duration, you can apply the LiveConfig.incrementalManifestUpdates configuration parameter to your player setup. By doing this to true, the player will do incremental manifest updates, so there can be more frequent polling without changing the segment duration. This can be used to keep a more stable buffer during the beginning of a live event when the manifest only has a few segments.
