Recommendations for Submitting an Application to Apple's App Store

iOS App Publishing Requirements and Recommendations

Before publishing your application, we recommend that you to take the following steps:

  • Deliver all content using HTTP Live Streaming (HLS)
  • Make sure all content intended to be displayed on Apple devices is encoded properly with the correct flavors
  • Make sure you have a 64Kbps audio stream for all content – Should be – stream with bitrate  lower than 64kbps
  • Verify that you are implementing the correct URL format when calling playlists
  • Download Apple verification tools and make sure you don’t receive any warnings or errors that may cause Apple to reject your application.
  • View your content on all supported display types (Smartphones / Tablets / Apple TV) and try both Wi-Fi and cellular networks (where possible) and confirm good viewing quality. If not, make sure you have enough flavors to support fallbacks and large screen high quality bitrate. If you don’t have access to all types of devices, we may be able to do provide assistance. Please contact Kaltura for further assistance.
  • Once your app is submitted, be patient as it may take up to few weeks for Apple to reply with an answer.

Cellular Network Support

If you would like to make your content available in a non Wi-Fi environment such as 3G networks, Apple requires you to enable a lower than 64Kbps, audio only, fallback flavor to support low connectivity scenarios.

Long Form Video Content Requirements

Apple requires that HTTP live Streaming is used for video content longer than 10 minutes or 5MB for every 10 minutes of data. For consistency and to avoid application rejection from Apple, Kaltura recommends you encode all relevant content for your app using HLS compatible flavors as described in this article.
