Problem with remote playback

[ice-p]

Hey Team,

I have some issues with remote playback from other networks and devices. In my wifi at home everything works fine but others users from remote have issues. It seems that Iphones for example seem to work fine, AndroidTV like FireTV Stick 4k seem to work from home wifi but not from other remote users. Playback starts and freezes or stopps.

In the GUI i dont see any issues.

Hardware is 12th Gen Intel® Core™ i5-12400 / 32GB memory

Log is here:

If you need anything else, im glad to assist in fixing my issue

thanks

Can you provide an ffmpeg log for the item transcoding? Looks like it's not using hardware acceleration (see lines 337+). Maybe a screenshot of your hardware acceleration options in Jellyfin web? Would be helpful to know how you're running Jellyfin (e.g., bare metal, OS, virtualization).

Here's the line in question IMO:

Code:

The ffmpeg command is not calling any hardware devices. Your iGPU on the i5-12400 should be set as the transcoding device to enable HWA.

Hey bitmap,

thanks for your quick reply.

Here is the ffmpeg log

Here is also a screenshot of HW Acceleration, its set to quicksync. I dont see any transcoding happening so far. When I am using my clients in my wifi everything seems fine.

The server is running as a lxc container in proxmox. But it should be setup correct to use hw acceleration as far as i can see. I also did a test to force trancsoding which was using the igpu on the host then. Attached a screenshot of this also.

There isn't any HWA since it is only transcoding the audio.

AFAICT, nothing is wrong on the server.  It is transcoding plenty fast.

What is your home Internet upload speed?

[ice-p]

Internetspeed is 250Mbit/s down and 50Mbit/s up. While my friend was testing I checked the internet connection, it was idling aroung 5Mbit/s. He has a 100Mbit/s download speed.

Are you using a reverse proxy? Do you use Cloudflare tunnels/proxys for remote access?

[ice-p]

Yes i use nginx. Can that be related to that?

[TheDreadPirate]

Using Nginx is fine (I use Nginx). But I'm curious what your Nginx config is. Can you share that via pastebin? Censor your domain name.

And using cloudflare proxies can also be a factor. Are you using cloudflare as DNS only? Or proxied?

[ice-p]

For cloudflare i use proxied. But i can test that without.

for nginx i will send you the config later.

thanks for your help.

[TheDreadPirate]

You need to disable cloudflare proxies, regardless. It is against their TOS to serve video and audio through their free tier proxy service.

And it can definitely cause problems like this.
