Charlie117 39 Posted January 9, 2020 Author Share Posted January 9, 2020 (edited) Ok, I'm the sole person Who else in this thread is supporting your controversial opinion then? Please do quote them. It's great that you were able to help certain users on this forum with issues that were resolved by forcing a transcode to AC-3 384 kbps. But that doesn't mean 640 kbps isn't generally supported. Calling this suggestion a bad idea just because you were proven wrong is seriously petty though. Edited January 9, 2020 by Charlie117 Link to post Share on other sites
Guest asrequested Posted January 9, 2020 Share Posted January 9, 2020 I'm not wrong. Less and less devices have an optical port. It's an antiquated standard. Just because at the pinnacle, it's possible, how many manufacturers will actually invest in the later standards when HDMI is ubiquitous? Very few. So what that means is that most optical solutions provided in the real world, will be crap. Which translates to more emby users having playback issues. You really think going backwards in tech is the way forward? I don't even have single device that now has an optical port. Nvidia Shield dumped it long ago. Some of the crap Chinese stuff has it. TVs have an optical output, but again how many have the newer standard. Not very many. And even if they did, the OS would need to recognize it and take a gamble that what's on the other end, also supports it. This spells nothing but problems. Link to post Share on other sites
Jdiesel 1034 Posted January 9, 2020 Share Posted January 9, 2020 Optical out from a TV to a soundbar is still extremely common especially for low end market. Link to post Share on other sites
Guest asrequested Posted January 10, 2020 Share Posted January 10, 2020 Optical out from a TV to a soundbar is still extremely common especially for low end market. Yes it is, and how many times have we seen on here people reporting audio problems because they are using optical? It's not like HDMI where it reports it capabilities. It's spin the wheel and see if it works. And if it doesn't, there's loss of audio, either a few channels or the whole thing. Link to post Share on other sites
Charlie117 39 Posted January 10, 2020 Author Share Posted January 10, 2020 (edited) It's an antiquated standard. Well, at least we agree on that. My original request was for an option to select 640 kbps instead of the default 384 kbps. That really shouldn't be an issue for anyone, because again 640 kbps is completely supported by the standard, but for those rare cases that it does cause problems, people can just revert to the default low bitrate 384 kbps. Win-win for everybody. Interestingly enough, these people with the aforementioned issues with 640 kbps should not be able to watch DVDs, Blu-rays, Netflix, Amazon Prime, Disney+ etc. because they all use either a DD+ 5.1 at even higher bitrates that get automatically converted to DD 5.1 640 kbps or they get a DD 5.1 640 kbps natively. By your reasoning, DTS 5.1 core 1509 shouldn't be supported at all. I wonder why I am not reading a ton of issues with all this... probably because it isn't an issue Edited January 10, 2020 by Charlie117 1 Link to post Share on other sites

zeroprobe 5 Posted April 12, 2020 Share Posted April 12, 2020 (edited) I echo the request. Custom bitrate would be a great feature. Or a convert to dd+ Edited April 12, 2020 by zeroprobe 2 Link to post Share on other sites
FrostByte 2646 Posted April 12, 2020 Share Posted April 12, 2020 +1 for custom bitrate and choosing which audio format. I like DD+ for TV. This should apply to music also though. The Shield seems to convert lossless WMA to 128bit AAC. I would prefer mp3 and something a little higher than 128 bits Link to post Share on other sites
zeroprobe 5 Posted April 12, 2020 Share Posted April 12, 2020 (edited) I've managed to mod the lib where the audio bitrate is. It won't be ideal to do every update.

zeroprobe 5 Posted April 15, 2020 Share Posted April 15, 2020 (edited) If anyone wants to try this mod until something official comes. Patch seems to find ok for x86/x64 variants Windows / Synology tested, if the below search is found it should be fine. Just find a Hex editor that supports a wildcard search for example Hex Workshop or Winhex. Find and open Emby.Server.MediaEncoding.dll On Synology, you need to copy to your NAS share location to edit it and put back after editing. In Synology this is located below, your volume name may be different. /volume1/@appstore/EmbyServer/releases/4.5.0.5-beta/ Telnet / SSH into Synology sudo su ls -l / Find volume name cd /volume1/@appstore/EmbyServer/4*/ cp Emby.Server.MediaEncoding.dll /volume1/MyNASShare (Your share name will be what you called it) Open in Hex Workshop / Winhex.

Or a convert to dd+ Dolby Digital Plus would be even better, especially now that ffmpeg supports it. DD+ is also backwards compatible with DD only devices:Is Dolby Digital Plus content backward-compatible? Because Dolby Digital Plus is built on core Dolby Digital technologies, content that is encoded with Dolby Digital Plus is fully compatible with the millions of existing home theaters and playback systems worldwide equipped for Dolby Digital playback. Dolby Digital Plus soundtracks are easily converted to a 640 kbps Dolby Digital signal without decoding and reencoding, for output via S/PDIF. The 640 kbps bit rate, which is higher than the standard 448 kbps used on DVDs, is fully compatible with all existing Dolby Digital decoding products such as A/V receivers, and can provide higher-than-DVD quality from Dolby Digital Plus soundtracks when played back through existing systems.https://www.dolby.com/uploadedFiles/Assets/US/Doc/Professional/dolby-digital-plus-faq.pdf 1 Link to post Share on other sites
staticmotion 1 Posted November 30, 2020 Share Posted November 30, 2020 (edited) I'll add my vote to this feature - both configurable bitrate and format would be appreciated. I am using a couple of Samsung TVs which don't support DTS; I'd prefer Emby server to transcode to PCM rather than relatively low bitrate AC3 - especially for the 7.1 soundtracks! thanks Edited November 30, 2020 by staticmotion typo Link to post Share on other sites
