Considerations

Keep this information in mind while using the PSDK for iOS.

• Playback is supported only for HTTP Live Streaming (HLS) content.
• Video playback requires the native Apple AV Foundation framework. This affects how and when media resources, including closed captions and timelines, can be accessed:
  • Timeline adjustments cannot be revised after the initial setup.

    For example, an advertisement cannot be removed from the timeline after it has played, so if the user seeks back in the presentation, the same ad plays again even if the normal policy would have been to remove it.

  • Depending on encoder precision, the actual encoded media duration may differ from the durations recorded in the stream resource manifest.

    There is no reliable way to resynchronize between the ideal virtual timeline and actual playout timeline. Progress tracking of the stream playback for ad management and Video Analytics must use the actual playout time, so reporting and user interface behavior might not precisely track the media and advertisement content.
