Control rendition order

Learn how to set the resolution preference order during adaptive playback in the FastPix Android Player.

Rendition order controls which resolutions the player prefers during adaptive playback. You can prioritize quick startup (ascending) or best quality first (descending).

Set the rendition order

1private fun startPlayback() {
2    player?.setFastPixMediaItem {
3        playbackId = "YOUR_PLAYBACK_ID"
4        renditionOrder = RenditionOrder.Descending
5    }
6}

Available modes

  • Ascending: 144p → 360p → 720p → 1080p. Starts with the lowest resolution for a faster startup, then increases quality as conditions allow.
  • Descending: 1080p → 720p → 360p → 144p. Starts with the highest resolution for the best initial quality, then steps down if needed.

When to use each mode

Use ascending order when quick startup matters (for example, mobile on cellular networks). Use descending order when you want the best initial viewing experience and can tolerate a slightly longer load time.

The player intelligently switches resolutions based on real-time network and device conditions while respecting the set priorities. This helps avoid sudden quality drops and maintains smoother playback.
