Hello,
I am currently developing a video player using Custom AVPlayer SDK and testing LL-HLS live streaming.
I encountered a specific error, CoreMediaErrorDomain -15418, during playback. I have searched through the official documentation and the forums, but I could not find any information regarding this error code.
I would like to inquire about the following:
-
Description & Cause: What does the error code -15418 specifically represent in the context of CoreMedia and LL-HLS?
-
Severity: Is this a critical error that halts playback, or is it merely a warning?
Environment Details:
- iOS Version: iOS 26.2
- Device: iPhone 15 Pro Max
- Stream Type: LL-HLS (Low-Latency HLS)
- Impact: Quality drops
Any insights or references to documentation would be greatly appreciated.
Thank you.
It appears that the LL HLS playlist provided is missing the required EXT-X-RENDITION-REPORT. That leads to the player dropping out of low latency mode. Note that the spec requires that every LL-HLS Media Playlist contain a Rendition Report for every other Media Playlist in the MVP
Should you find that a missing rendition report is not the issue, please file a bug report following steps at https://developer.apple.com/services-account/download?path=/iOS/iOS_Logs/CoreMedia_Logging_Instructions.pdf
