Kramerika 16 Posted September 8, 2017 Share Posted September 8, 2017 I just noticed that all of my Fire TVs are transcoding everything that I play on them in Emby. All of my files are MKV with H.264 video, PGS subtitles (although I have them off by default), and either DD stereo or 5.1 or DTS 5.1 audio. This is for 3 different FIre TVs on completely different TVs. These TVs do support output of DD audio. I have audio set to direct in Emby for all of them. I cannot get them to direct play anything. What am I missing? They were able to direct play before although I can't pinpoint when it changed as I hadn't noticed until now. I prefer to direct play as much as possible to save server resources unless there is good reason to transcode. I sent a log as MediaServer just now.

Luke 37100 Posted September 8, 2017 Share Posted September 8, 2017 Hi, can you please provide the emby server and ffmpeg log? you can learn how to do that here: https://emby.media/community/index.php?/topic/739-how-to-report-a-problem/ thanks !

Luke 37100 Posted September 9, 2017 Share Posted September 9, 2017 Hi @@Kramerika, there's only two examples of a full transcode and that is due to burning in DVDSUB format subtitles, which are not natively supported by fire tv. The other logs are just audio conversions. If you enabled audio downmixing in the app then that could be why the audio conversions are happening. Does this answer your question?

Kramerika 16 Posted September 9, 2017 Author Share Posted September 9, 2017 I do not have downmixing enabled. I have it set to direct. Why it is converting DD stereo or 5.1 or DTS 5.1? Link to comment Share on other sites More sharing options...

ebr 14925 Posted September 9, 2017 Share Posted September 9, 2017 Dts is going to have to be converted on the fire. For Dolby it depends on the equipment involved. Please play one of these items and send a log from the app. Thanks. Link to comment Share on other sites More sharing options...
Kramerika 16 Posted September 12, 2017 Author Share Posted September 12, 2017 I just sent logs as MediaServer from 3 different Fire TVs connected to 3 entirely different TVs via HDMI. All of the TVs do support DD and DTS. None of the TVs are connected to a receiver though nor are the Fire TVs. These are 2nd generation Fire TVs. The first log also was sent following a break where the stream froze with a volley timeout error. Not sure what happened there. Link to comment Share on other sites More sharing options...
ebr 14925 Posted September 12, 2017 Share Posted September 12, 2017 DTS is not supported by the Fire TV so it will have to be converted. The DD tracks you played were high-bitrate ones (over 448kb/s) and we've had people reporting audio dropouts trying to direct play those. Upon investigation, we found that the Fire specs only state support for DD at 448kb/s so we are converting to that bitrate for proper playback.

I can't seem to discern why it is transcoded/remuxed. I thought it was the audio bitrate but the native file is 448, I believe 448kb/s is the general max recommended bit rate for DD, so it is not just the Fire platform, probably a good choice for most clients! ffmpeg-remux-6a04148d-d9e9-42bb-b5cd-8bb05f8975ae.txt Thanks, -vicpa Edited September 13, 2017 by Vicpa Link to comment Share on other sites More sharing options...

A new version was submitted to Amazon this morning. Once it passes review, it should resolve this. 1 Link to comment Share on other sites More sharing options...

Kramerika 16 Posted September 13, 2017 Author Share Posted September 13, 2017 @@Kramerika does this address your concerns? Disappointing, but I guess so. I'm just ripping DVDs and blu-rays out and passing through the DD audio on compression, so I'm not changing the bitrate from what the DVDs or blu-rays included with the native audio track.

ebr 14925 Posted September 14, 2017 Share Posted September 14, 2017 Your DVDs should be fine (with the new version on its way out) but some BD DD tracks are likely 640kbs. Audio only transcodes are pretty light-weight. Shouldn't have much of an impact. Link to comment Share on other sites More sharing options...
