Arnagos 0 Posted February 17, 2019 Share Posted February 17, 2019 (edited) Hi I've bought a new Sony KD AF8 OLED TV and installed the Emby app. While testing it I noticed that almost everything is getting transcoded even though the TV supports all of the supposedly not supported formats. The only things that have worked so far are: h264/5 with AC3 or AAC audio with ASS or SRT subs. Everything else isn't working. I tested everything mentioned above and: - FLAC Audio - DTS Audio - DTS-HD Audio - Dolby True HD Audio - 10 Bit Video - PGS Subtitles Additionally if I have a video with a not supported audio format and enable ASS subs the whole video is getting transcoded even though both ASS and the Video format are supported. If I disable the subtitles the video is transmitted as direct stream again. Emby-Version: 1.6.86g Server-Version: 4.0.2.0 Best regards Edited February 17, 2019 by Arnagos Link to comment Share on other sites More sharing options...
ebr 14947 Posted February 17, 2019 Share Posted February 17, 2019 What leads you to believe that the TV supports all those audio formats? Sony TVs do not support DTS or the HD audio natively. But, in those cases, it should just be converting audio. Hard to say though without seeing a specific example. Link to comment Share on other sites More sharing options...
Arnagos 0 Posted February 17, 2019 Author Share Posted February 17, 2019 (edited) I checked the product page and it lists support for DTS, most Dolby formats and FLAC. Though you are correct that not support for DTS-HD and Dolby True HD are listed. The thing is that I have the TV connected to a Marantz Receiver via ARC HDMI. This Receiver supports absolutely every audio format I listed above and I actually thought that the audio would just be bitstreamed to it without getting touched like the PC Theatre Application does. The thing that's really bothering me is the video transcode. I see no reason why an unsupported audio format should trigger video transcode just because substitles are there. And why does 10 bit video not work? The TV supports HDR, even Dolby Vision, so 10 bit should be supported, I think. The server isn't strong enough for transcoding and the quality reduction of the transcode is so extreme that I really don't want that to happen.

Luke 37166 Posted February 17, 2019 Share Posted February 17, 2019 Can we go over a specific example? Thanks. Link to comment Share on other sites More sharing options...
ebr 14947 Posted February 17, 2019 Share Posted February 17, 2019 Is your TV running Android 8? If so, Sony has broken DTS support on that OS version. As for your other questions, we will have to look at a specific example. Thanks. How to Report a Problem Link to comment Share on other sites More sharing options...
Arnagos 0 Posted February 17, 2019 Author Share Posted February 17, 2019 (edited) Here's the log of a video that is encoded h264, 10bit and has FLAC audio with ASS subs and transcodes (supposedly because of the audio codec). I additionally send the log via the app as described in the link.Time: 18:48User: arnagos Log.txt Edited February 17, 2019 by Arnagos Link to comment Share on other sites More sharing options...
ebr 14947 Posted February 17, 2019 Share Posted February 17, 2019 Hi. Did you forget to attach the ffmpeg log? Multi-channel FLAC in video files is not supported. Link to comment Share on other sites More sharing options...
Arnagos 0 Posted February 17, 2019 Author Share Posted February 17, 2019 I don't know what you mean? The log is attached to the post above and the FLAC Audio is normal stereo. Link to comment Share on other sites More sharing options...
ebr 14947 Posted February 17, 2019 Share Posted February 17, 2019 The log wasn't there when I first looked. I will need Luke's help on why the video is transcoding. It should only be converting the audio as far as I can see... Link to comment Share on other sites More sharing options...
