I gave an update above, right?

@LukeI was asking for any new news

@LukeI know you are busy, and I really do appreciate the time you have given me. I have spent a great deal of time trying to figure out why the Emby server doesn't fetch the next channel in your "virtualTVexample code. When a program is selected to play (by clicking it in the EPG) it always starts at the beginning. It's interesting that the duration timer at the bottom of the Emby client shows the correct playing time. Also, when the program ends (and again when the duration timer ends) the following error is thrown.

From my novice knowledge I assume that this error was caused by the server failing to find the next program to play. To remedy the problem the server fetches channels again. I am sure the server is doing this because it believes it's out of channel data.

@Luke Can I modify the "Ensure Channel Schedule" code in the "VirtualTvExample" so it will provide to Emby the next program to play. For example, as a temporary fix, can I reload the channel data at the proper point to start playing the next program and then tell Emby to start playing it? If this idea is worthless, please give me some pointers on what I can do.

Any success I have, I will share with @pünktchenand he is always welcome to use freely any of my code in any way that he chooses.

No, this comes from the EPG. It will just start playing the channel at the current time, meaning whatever is currently on the channel.

March 8, 2024

@Luke I discovered this a short while earlier today.

Is the problem in the server code? I ask this because the error log says the server was not able to find the next program to play.

Should I abandon this project? Will a fix be available anytime soon?

Vic

Edited March 8, 2024 by VicMoore

March 10, 2024

Where does it say that?

March 10, 2024

@Luke I read it in the Emby log. I will try and recreate the event and send you the log. I have been watching via log messages each time the server calls anything in the Tuner code trying to understand why the next channel is found OK in Chrom but not with Android. Sometimes even Edge goes to the next program OK. As a temporary fix I was considering sending a playlist to the client when a program is requested. I know @pünktchenhas this working. I am only interested in this solution for my own use. Do you have any ballpark idea when this problem will be solved?

@LukeWhile waiting for the problems associated with playing programs in the virtualTvExample code, I decided to try a simple work around. One similar to what @pünktchenis doing. In the GetChannelStreamMediaSources task I added a small program that builds a playlist from the schedule info and then I send that playlist to the client with a "Play Now" command. I have tested this idea and it works. I have experienced one strange problem when clicking a movie to be played. The client plays the playlist OK, but it adds trailers for the movies to the front of the playlist. TV shows are played OK. All of the code is below. Now programs start at the proper time and programs in the schedule play sequentially.

Do you have any suggestions on how to improve this idea? Of course, when the changes for the virtualTvCode is ready I will remove this code.

@LukeIt's been almost a year, has any progress been made? By progress I mean fixing the Emby players so they will advance to the next video when the current one finishes, and the issue of starting at the current time rather than always at the beginning of a clicked video.

All apps should have this now except for Roku. To use on Android TV, make sure to be testing with the standard Emby android app.

If you see an issue anywhere let me know and we'll look at it. Thanks.

December 12, 2024

@Luke the android reference client (fire TV), the Emby Web Client, and my Samsing TV Emby client all fail to start programs at the current time. They always begin at the start of the current program in the Emby EPG.

You need to be using the Emby standard android app:

This is what I meant that they should all have. So you can confirm that?

December 13, 2024

@Lukeare you implying in the reply above that "fixing" the Emby players only included changing them so that they advance to the next video when the current one terminates? If so, the players will quickly get out of sync with their EPG. I speak from much experience.

As you know, I have created work arounds. I don't mind doing this, but it is not my fight. It should be easy to fix this problem. You can do it as I have on the server or fix the players. You said this yourself.

Does this problem have a low priority because you plan to replace the current LiveTV architecture with something new?

I am grateful for the "virtualTVexample" code that you gave me. I have learned much from it and have added to it new abilities. It was a blessing.

Vic

December 13, 2024

It is a two part problem. I'm saying that is step one. Is that part functional? The second step is to be able to allow the channel to set the starting position in the video.

It is in the code. Hasn’t really been tested.

@LukeI tested the Android reference client, the Samsung Android client and the Emby Web Client. Only the Web Client worked properly. The other two did not work for either playing the video at the current time or playing the next video when the current one finishes. I found it interesting that the progress timeline for all of the clients was working correctly.

I know you are very busy, and @pünktchenand my requests are a low priority, but it has been one year. I am OK with you saying these problems will never be fixed. I would then know what to do. Does this problem have a low priority because you plan to replace the current LiveTV architecture with something new?

@Luke you are doing and have done a great job. None of my remarks are an attack on you.

I have been digging deep into the Emby "Live TV" architecture. I have learned so much about how you employ C# building solutions. I see your professional training. Learning is more important to me than creating a TV solution. @pünktchenis much better at that than me.

Vic

We’ll take a look at it. Thanks.

@LukeWhen you play a program from the EPG the media under the current time stamp is played and it starts that media from the beginning, rather than the current time. When this happens, you will have trouble transitioning to the next media in the EPG because in a short time the media at the current time will not be what you expect. For example, when the media completes playing, the current time has passed well into (or even past) the next item in the EPG. I observed this behavior in my testing.

An interesting point is that the progress display bar at the bottom of the Samsung android client properly identifies where the video should be playing, even though the video is playing from it's beginning. In other words, the client knows where it should be playing, its just not doing it. I suspect this problem is move common in your variety of clients than you suspect.

The point I am trying to make is that the problem does not divide into two parts as you suggested.

Vic

@LukeI would like to suggest that you fix this problem in the server rather than in the clients. When you send the session command to start the video, you can just add to it the number of ticks to skip. Just an idea from someone unfamiliar with the side effects, like the difficulties with transcoding, that this idea may involve.

Vic

A simple solution for the "start" problem maybe could be ContainerStartTimeTicks of MediaInfo. I've never seen any value other than 0 for this property. The plugins could set the required start offset and the requesting client then would request the stream with this value the same way it does normally for any other in progress item.

What is the Android reference client? The Android standard app works fine for me. The Android TV app not. But Luke already said that this app will not get needed code updates.

What is the Samsung Android client? Do you mean a smartphone? Because Samsung TV's don't have Android!

Btw. the Windows app also advances to the next program.
