[BUG] Auto Adjust Quality Broken

Received no response on the General Forum, so will try here also.

Auto Adjust Quality isn’t working with Linux PMS and any client.

Just tried playing a 1080P 15mbps stream on a client with download WAN speed of around 8mbps. No other streams were active at the time.

Buffered within a few seconds and there was no attempt to downgrade quality.

Started playing again for a bit, then buffered again, still attempting to play at the original 1080P resolution all the while, saying transcoding was throttled.

Transcoder isn’t the issue. If I manually limit transcoding to 4mbps on the server end- no streams buffer at all and server happily transcodes multiple streams at once (up to around 8 from experience)

Server Stream Status when buffering occurs again: http://imgur.com/3hl6loq

As you can see, error message on client related to lack of bandwidth (not server power), and server status shows transcoding as throttled when buffering is still occuring. All screenshots show the server attempting to send a 1080P stream. It never downgrades to a lower quality to which the client can receive the stream.

All of which suggests the client doesn’t have enough bandwidth to receive the stream.

This is normally when the Server then downgrades the quality of the stream to fit with available client bandwidth. But it doesn’t occur.

Bump. Still broken

Bump.

Bump again

Having the same issue.

Bump again…

An update to the issue has been posted by one of the devs.

Hi @“MovieFan.Plex” thanks for the update.

Auto quality adjust seems to work with the main user now (which is great- thanks) but not for managed users?

The ABR feature is currently only enabled for the Admin user during this initial release. We will evaluate how it will apply to other users in the future.
