Failed Transcoding When Remote Streaming To iOS

Plex Media Server
1

Server Version#: 1.19.2.2737
Player Version#: iOS 6.11 Release and iOS 6.12 (20335) Beta

When trying to initiate a remote streaming sessions on iOS, I get the error

Could Not Transcode Because: Not Enough CPU for Conversion of this Item

The PMS logs show the errors

[FFMPEG] - Error: cannot create compression session: -12915
[FFMPEG] - Try -allow_sw 1. The hardware encoder may be busy, or not supported.
Codecs: avcodec_open2 returned -542398533 for encoder 'h264_videotoolbox'

Disabling both hardware accelerated decoding and encoding, fixes the above PMS errors, but stills gives the same error on the client and give the below error in PMS

ClientProfileExtra: video transcode target already exists for streaming hls

If disabling hardware acceleration fixed the issue, I would (reluctantly!) leave it off, but the fact that it still errors when disabled is very confusing.

Cheers, Jake

Edit: Fixed square bracket

Try using the experimental player in ios, found in the advanced settings

Thanks, you’re absolutely right, I forgot to mention that I have tired with both the new, default video player (formally experimental video player) as well as the old video player. I have identical issues on both PMS and client for both players
