dbowles1975 25 Posted May 25, 2019 Share Posted May 25, 2019 (edited) I'm prepared to send logs when I get home but I just wanted to start this topic while it was on my mind... I was recently playing a file with DTS audio on my Fire Stick and I started having freezing issues. Of course it was transcoding the audio but it also told me that the audio bitrate had exceeded the limit. The video would freeze every 15-20 seconds for roughly 2-3 seconds. I switched to another file... this one with Dolby Digital. This one did not transcode but it still said the audio bitrate was being exxceeded. It was running at 640 Kbps at the time. I also noticed that the "stats for nerds" info indicated the file was still being transcoded although the dashboard said that it was not. It was also strange that the transcoding percentage continued to climb beyond 100%. Emby Server is running on a very capable Windows PC and at the time this was happening I checked resources and everything looked fine. The Fire Stick is connected wirelessly but within 15' of an AP and all network tests show a rock solid and extremely fast connection. I also tried a wired connection and noticed the same results. Any ideas? Edit: I was able to solve the issue by uninstalling Emby. Edited June 9, 2019 by dbowles1975 Link to comment Share on other sites More sharing options...
kikinjo 172 Posted May 25, 2019 Share Posted May 25, 2019 I never understanded this "bitrate over the limit" to be honest, i have a android client on 200 mbit fiber connection and he also gets trans-coding most of the times, even he choose 100mbit in max bit-rate settings in android app on firestick 4k. The funny thing is that movie bitrate is like 8-9 Mbit (altogether video and audio). We tried internal access external access, does not matter it just spills bit rate exceeded and transcode. It would be nice that devs make a detailed wiki article about this and explain it... Link to comment Share on other sites More sharing options...
ebr 14958 Posted May 25, 2019 Share Posted May 25, 2019 Hi. The Fires don't support DTS at all and only support DD up to 384kb/s (we may need to check some of the newer models to see if they've relaxed this restriction). Link to comment Share on other sites More sharing options...

I was aware they didn't support DTS but was unaware of the bitrate restriction. Still, should video be freezing when only the audio is being transcoded? That seems odd to me.

I did notice that playing the exact same file on the exact same device just now it was only transcoding because of unsupported audio and not because the audio was exceeding the bitrate limit. Bitrate was 1.54Mbps. Edited May 27, 2019 by dbowles1975 Link to comment Share on other sites More sharing options...
neik 838 Posted May 27, 2019 Share Posted May 27, 2019 Hi. The Fires don't support DTS at all and only support DD up to 384kb/s (we may need to check some of the newer models to see if they've relaxed this restriction). Amazon does offer EAC3 sound for some series, do they also only have 384kb/s or is it simply limited on the FTVS? Where did you find that information? I looked at their developer page and couldn't find anything. Link to comment Share on other sites More sharing options...

I am not 100% sure but I'm quite sure that my FTVS Gen. 2 does direct play AC3 640kb/s without downmixing if I force it to, by disabling remux/transcode in the user settings. I will give it a try once I'm home and feed back. Link to comment Share on other sites More sharing options...

With the file direct playing if forced to, I am wondering why it does remux at all?! Shall I provide any logs? Link to comment Share on other sites More sharing options...
