Improving Video Playback with ExoPlayer
summary
Tests show replacing DASH with use MP4 for <45s reduces playback errors by about 5% and raises video views; adding background prefetch via use DownloadManager prefetch trims time-to-first-frame (~2% improvement) and nudges views up ~1.7%. Tuning ExoPlayer’s buffering with tune LoadControl buffers (keep min/max equal, lower values for short clips, prioritize time over threshold) yields faster starts (more under 500 ms) and noticeably fewer long loads. Also enable decoder fallback to recover devices lacking hardware decoders.
