DLNA always transcodes mp3 when using BubbleUPNPdlna transcoding
Posted 22 October 2019 - 08:17 AM
Unfortunately I never managed to get my Emby DLNA configuration to work properly. So after some time I am making the last attempts before my annual subscription expires. My configuration: Synology NAS with Emby v18.104.22.168, Yamaha RX-V777 Home Theater for DLNA renderer and android smartphone with BubbleUPNP as DLNA control point. My library consists of only two formats: mp3 or flac. When I run flac everything works perfectly, while with any mp3 Emby transcodes and everything freezes. I have to switch off all devices to get the working dlna back. I attach the server and transcoding log. This unfortunately happens only with Emby, forcing me to use other dlna servers. Does anyone know if there is something I can try to solve the problem before abandoning Emby?
If it can help, I noticed that the URL called for the stream has a double encoding of "&", and in fact if I try to simulate the call from a browser, with double encoding Emby does the transcoding which does not happen without double encoding; example:
(note the "&amp;") emby perform the transcoding;
Emby play without transcoding
I don't know how and why double encodings happen, but this is in the log.
Any help is appreciated. Thanks

Thank you very much Luke! I would be very happy if we could solve this problem. Of course I can install the beta version, but I couldn't find the version for synology armv7. Maybe I could do tests on PC with the windows version? Always if the problem is not related to the hardware... Meanwhile, thanks for the support!

I don't know if i must open a new topic in the Server Test area, however i installed the beta server 22.214.171.124 on my windows machine. The problem is the same with my NAS and described above except that transcoding does not hang all systems. I don't know why Emby decides to transcode from mp3 to the same mp3, but this happens only when I transmit via DLNA to my Yamaha home theater and only for mp3 formats (flac works very well). If we could prevent any transcoding, the server would work fine. I did two tests and attached the logs: the first using the dlna function "send to" directly from the browser, the second using BubbleUPNP from an Android smartphone. The results are the same. I remain available for testing. Thanks

Please try again with the next beta update. Thanks.
Thanks Luke. I've tested the new beta version 126.96.36.199. I can finally confirm that unnecessary mp3 transcoding no longer occurs and my home theater works fine, but the log fills up with errors for every mp3 I play through dlna. I attach the server log and as you can see there are many errors that report: "Error MediaSourceManager: Error getting media sources"... It's strange because in any case the mp3 is played despite a very small latency compared to the flac. Did I configure something wrong?
