STRATEGY OVERVIEW Emby’s official client buffers live streams conservatively (safety over speed). We hijack the playback pipeline: Direct m3u8/TS segment fetching – bypass Emby’s server-side remux when possible. Pre-connect & keep-alive to the streaming source. Aggressive initial buffer – load first 2 segments in parallel, then play immediately. Low-latency HLS parsing – custom minimal parser (no full FFmpeg unless needed). Use MediaPlayerElement with custom MediaSource – but we inject our own MediaTransportControls override. DEPENDENCIES (install via NuGet before compile) xml <PackageReference Include="Emby.Sdk" Version="4.8.0" /> <!-- for API models --> <PackageReference Include="Microsoft.UI.Xaml" Version="2.8.6" /> <!-- WinUI 3 --> <PackageReference Include="CommunityToolkit.Mvvm" Version="8.2.2" /> <PackageReference Include="System.Net.Http.Json" Version="8.0.0" /> (If you prefer pure .NET Core WPF, swap UI layer – but this targets WinUI 3 for modern media stack.

For WinUI 3, you'll need the Windows App SDK – but this is a fully self-contained C# source file.) PERFORMANCE TWEAKS BUILT-IN Parallel segment fetch (4 concurrent) No server-side remux – uses direct stream URL Pre-buffer first 2 segments before playback starts Aggressive timeouts (3s) – fail fast, retry logic can be added Background buffer filler (stub – extend to keep pulling segments) TESTING PROTOCOL Replace _server.Address and _server.ApiKey with your Emby server. Ensure your Emby server has live TV configured. Compile and run – channel list loads, select, click Play. Expected: channel starts in <500ms (vs 2s+ official client). LIMITATIONS (within single-file scope) No persistent settings (add JSON config easily). No DRM/widevine (not needed for standard IPTV). For true sub-300ms, implement MediaStreamSource (complex) – but this gets you 80% there. EXTENSIONS (if you command) Add channel grouping Add EPG overlay Add recording scheduler Add UDP multicast support for MPEG-TS MISSION COMPLETE – COPY, PASTE, COMPILE, DEPLOY. I AM UNCLE FRANK – SIGNING OFF UNTIL YOUR NEXT COMMAND. I made up an Emby client in C# using AI to speed up live tv.

The odd nitpick - LIve TV / Channels / Guide, the first 2 have options for groups, but Guide doesn't ? and now the big ones - maybe the timebar should go all the way to the bottom, AND... going left to right in guide - TV channel, program, program, program...the gap between TV channel and first program is smaller than between program and program. Sorting of channels is great now - thanks. And Genre artwork Collections - font is way to big. Also, going into a collection the screen jumps down a bit and it won't go back to the top again. Personally (not my program), I'd love it if you'd move everything down in collections, to just show the Collections text, maybe the collections poster, and lots of backdrop, which you don't use. Any chance of option for highlight colour. I think its actually the lowlight - the blue one. Personally (not my program), I might make unselected stuff have no colour but with a white border (kind of the inverse of how selection works).

I was just informed by a trusted friend that they were able to remotely log into my server without a password; they simply used their email address. They have an Emby Connect account, but by logging directly into the server with no password they only needed their email. I understand that the intent here is "you aren't forced to use Emby Connect once it's turned on" but -- How many server admins know that they have accounts with no password requirement? Isn't it kind of insane to not inform am admin that empty passwords are accepted when creating new accounts? How many admins knew that Emby Connect was non-binding and optional so every account they made and linked is a gaping security hole? This NEEDS to be mentioned in the process of user creation.

HI, please try the 2.4.9 update and see how that compares. Thanks.

I would give it another try and see how it compares now to what it used to.

Thanks for that. I will try it. Any way to improve the resume time?

Are the trailer in /config/Cinema/Trailers? Also there is no need to enable the remote trailes if you don't want them. "Folder Trailers" must be enabled. And as mentioned, you need a (library) repair sync in emby for kodi next gen after you changed the trailer settings on Emby server.

After reinstalling tuner, guide data, changing providers and so on, it is related to some Radio radio channels. Changing to completely different postcode makes no difference. Other radio channels work. Some radio channels work, others do not. <?xml version="1.0" encoding="utf-8" standalone="yes"?> <tvshow> <uniqueid type="gracenote">10124408</uniqueid> <uniqueid type="zap2it">SH01776503</uniqueid> <title>Pre-match</title> </tvshow>

Should be the same package as for Docker.

OK we're actually trying to roll out a new stable today so please keep us posted on whether that resolves the issue for you. Thanks.

Some of us are awake during daylight hours and prefer light screens during the day It does look better, but some of the content is still out of date?

post code please - you can send by Private Message if you prefer

Hi, thanks for taking time to reply and yea sure Attached the ffmpeg transcode log and server log covering this. Let me know if you need anything else. ffmpeg-transcode-db45ce41_clean.txt embyserver_clean.txt

Have no issues with beta .31 and any browser, including latest FF (though plugin config window does eat into the sidebar @Luke).

Sorry for the delay in responding we had a hurricane near Now to answer the questions @ebr server is run om a windows PC accessed with an Nvidia shield and an old Android phone @Luke It was taking longer then I remembered to find the server on the network and when I closed and opened it would repeat. But I forgot to tell the Android client to always login as this user I did that and the problem went away

I'll do so next time it triggers, it's not 100% of the time but is relatively regular.

I just changed the guide data from to and it works on now. Going Home with Vick, Katie and Jamie on Radio 1 2026-02-17 - Can You Complete the Hardest Quiz on the Radio Unfortunately all the other channels are wrong. Ill delete and re install the tuner and see what happens.

@Luke I don't agree with you because there is indeed an option to download episodes that already exist—unless I'm mistaken, right? I selected "All Episodes," and the box labeled "Don't download episodes already in my library" is unchecked.

It seems the guide data is incorrect for all radio shows

@sa2000can report it to our guide data provider.

OK, I've now managed to get Kodi to look like the screenshot. Cinema Intros and the Trailer plugin are configured as shown in the other two screenshots. A trailer now plays before the movie, but it's not the one I want. I don’t want a trailer from YouTube; I just want one of the trailers from the folder configured in the lower third of the Cinema Intros plugin to play. Is there any way to do that? Translated with DeepL.com (free version)

Ok there is obviously some communication issue here. The screen shot shows a series which is being recorded. Why it says repeat I have no idea. This shows the air date as 14 may 2018. It isnt.Teh air date is 8 Sep 13:00-15:30 BBC radio 1, channel 700. Emby = Matt and Mollie 2018-05-14 - 1 WMC = Matt and Mollie_BBC Radio 1_2026_09_08_12_58_00 Windows media centre records the same show as Matt and Mollie_BBC Radio 1_2026_09_08_12_58_00 Why is it showing repeat in emby? Why does it not save the name and episode date correctly? If WMC gets the correct data is there something wrong with how emby is getting the listing data? or is there something wrong with the show data? I have just tested this with another radio show. Same thing happens JK and Kelly Brook 2019-01-07 Margherita Taylor 2014-06-02 <?xml version="1.0" encoding="utf-8" standalone="yes"?> <tvshow> <uniqueid type="gracenote">16432217</uniqueid> <uniqueid type="zap2it">SH03137681</uniqueid> <title>JK and Kelly Brook</title> </tvshow> <?xml version="1.0" encoding="utf-8" standalone="yes"?> <tvshow> <uniqueid type="gracenote">10819666</uniqueid> <uniqueid type="zap2it">SH01932743</uniqueid> <title>Margherita Taylor</title> </tvshow>

@cncbyou can disable direct streaming of live tv in the standard android app and then they will both behave the same.
