Sony S570 - MKV Audio Problems

I have noticed that when I stream from an MKV FIle the Audio goes from English dts 1500kbit/s Down to 198 KBPS. Does that seem correct ?

Also is there a way to test Audio Bit rate in a file ?

Is it possible to stream full HD Audio Uncompressed using Serviio ?

Re: Sony S570 - MKV Audio Problems

I think we need a sticky topic with a Sony FAQ :)
The situation currently is that all mkv files are remuxed to m2ts which the player streams far better over wifi (less stuttering). Unfortunately FFmpeg cannot remux dts properly and produces a silent file so instead it's transcoded to ac3. This will default to 2 channel in the Serviio console settings. Unfortunately it seems that if you select to keep source channel count the dts to ac3 conversion breaks. Both of these problems will hopefully change in future builds of FFmpeg. See here if you would rather have player-native mkv dts support at the expense of smooth wifi streaming (if you're on a wired connection for instance):

If it's just a one-off, you can use a tool called TSMuxer to manually convert the file from mkv to m2ts. This tool can remux the dts stream properly and it will only take a few seconds even for a 4GB file. Then add the m2ts file to your Serviio library.

You can get comprehensive codec and bitrate info on any file by running FFmpeg -i on it from Serviio's lib folder:
