Audio Problems Android Tv - Qnap Server

July 30, 2018

Hi I have a Philips Android TV. I output audio via optical to Integra 70.4. The Integra show Dolby when viewing TV. If I switch to Emby App all I get is pcm. I have checked TV is set to multi-channel and Emby app is set to Auto for Audio. Emby server on Qnap is 3.5.1 All transcoding settings on Qnap are as factory installed except for Hardware Acceleration which is set to Video Acceleration API. Stats for nerds state 5.1 audio channels. Does anyone have any suggestion please ? Are there settings I'm not seeing ? Thanks Gary

Hi Luke Thanks for answering. I have uploaded the logs via Android TV. I have included screenshots of TV & Emby playing and their respective outputs to Integra

Emby Output. Thanks Luke

Ok, @@ebr will take a look at that and let you know what he thinks. Thanks.

Hi. Can I please see the ffmpeg log that is generated on the server when you play that first item?

Thanks.

BTW - the app is sending 5.1 PCM but the TV is converting it to stereo because an optical connection cannot carry more than two channels of PCM.

Hi ebr

Here is the ffmpeg txt file. Is there a way for the app to send DD rather than pcm ?

[mpeg4 @ 0x1cc5740] Video uses a non-standard and wasteful way to store B-frames ('packed B-frames'). Consider using the mpeg4_unpack_bframes bitstream filter without encoding but stream copy to fix it.
