Jellyfin-web: Arbitrary low bandwidth limit on iOS

[timo95]

Describe The Bug

The iOS App and Browser have a bandwidth limit of 800 Kbps.
This prevents direct streams and forces transcodes to 800 Kbps.

Offending line:
https://github.com/jellyfin/jellyfin-web/blob/800e5166831ebd9022bba2798fa9432557d7178a/src/components/appRouter.js#L254

Using 10.6.0, it didn't want to start the transcode at all, so i had to revert back to 10.5.5. Thats why the following examples are based on 10.5.5. 10.6.0 showed a similar log for the bandwidth limit, but stopped direct playback after 0 seconds and didn't try to transcode after that.

Steps To Reproduce

1. Remove bandwidth limits lower than 800 Kbps
2. Play anything with iOS (App or Browser)
3. Bandwidth is too low for direct play and transcode is limited to 800 Kbps

Expected Behavior

It direct plays or transcodes with any bitrate.

Screenshots

System (please complete the following information):

• Platform: iPhone
• Browser: App and Safari (iOS)
• Jellyfin Version: 10.5.5 and 10.6.0

@anthonylavado I can confirm this, I have been processing all videos through ffmpeg down to below 800kbs for months just to get them to direct play on ios without transcoding.

[gnattu]

Yes, and this caused https://github.com/jellyfin/jellyfin/issues/3957

[Wepwawetcode]

I edited the following function in /jellyfin/web/components/appRouter.js

From

function getMaxBandwidthIOS() { return 8e5 }

to

function getMaxBandwidthIOS() {
    return null
}

this fixed my issue on IOS 14.* for my iPhone devices.

[RemoteMedia]

I have been having this same issue. I’m on iOS 14.1 and access my content remotely usually. However, this problem also occurs when on the same internal network.

I am having no issues with flac files, only mp3 files with 320kbps and 48000hz. These files work on a pc within the same internal network accessing via the same means (wifi).

I have tried in the native iOS app, and on the following browsers - brave, chrome, Firefox, safari.

I have found the issue with at least 3 files now.

The issue continues even with the amendments made to the docker container appRouter.is as suggested by @Wepwawetcode

Each time I test I am saving my settings and restarting the docker container to ensure a restart has been pushed through.

I have also attempted with audio transcode on and off over all browsers with wifi and cellular to no avail.

Any other tips or confirmation would be appreciated.

Edit:

I can actually see in the logs whether my remote access and remote transcoding is on or not that I’m having a section of the error advising

EnableRedirection=true&EnableRemoteMedia=false

I’ve also attempted and replicated this on the admin and a user account

Edit 2: @RemoteMedia it does work on docker after all I’m not sure if it was something held in cache, maybe restarting nginx if you have it behind that.

And you will want to create a volume for that file so it is persistent with jellyfin updates. but hopefully this will be fixed in the next release and you will not need to.

for reference for others using docker the location of the file after you docker exec -it container-name /bin/bashis /jellyfin/jellyfin-web/components/appRouter.js if using nano Ctrl + w to find the "getMaxBandwidthIOS" as it is minified and should help you find it faster. Thank you @Wepwawetcode

@Bellusterra are you saying 48000hz .mp3 files work on your iOS device? I’m not having issues with any other .mp3 or .flac files since amending approuter.js only with 48000hz .mp3 files playing back on iOS devices

[Bellusterra]

That I couldn’t tell you, I have only now tested it with .mp4 video files over 800 Kbps. Which now, with the change suggested by @Wepwawetcode, direct play on iOS devices when they didn’t before.

[RemoteMedia]

Thanks, I’m having no issues with these files now as we since modifying as suggested.

It’s only the .mp3 codec sampled at 48000hz which I have opened an issue for

[flyinRyan424]

just tried this fix to appRouter.js on Windows and still having issues with some video playback on iPhone 6s - i.e. bitrate 1655 kbps
