Provide logs as requested and I will review it. You might also want to check Config.Demuxer.ReadLiveTimeout (default is 20sec timeout) so if you get a timeout just increase this (in Ticks).

do we have any timeout event? so that its easy to play again.

@saman1832 you can use Player.MainDemuxer.TimedOut event for that (better use Task.Run to pause/re-open etc.)

saman1832 · 2023-11-07T16:34:51Z

@SuRGeoNix I tried Player.MainDemuxer.TimedOut but here Player.MainDemuxer is null so getting null exception .
Then i tried Player.VideoDemuxer.TimedOut but when i try to openasync url inside this, i never get debugger on opencomplete event and UI is also getting stuck. I ahve also sued task.run with dispatcher

SuRGeoNix · 2023-11-07T17:51:02Z

Logs!

saman1832 · 2023-11-07T17:54:10Z

I have applied Player.MainDemuxer.TimedOut successfully but when I am debugging the code when timeout hit one by one I am able to play again. But without debugger its not restarting.
code inside timeout method:
Task.Run(() =>
{

            Dispatcher.Invoke(async() =>
            {
               
                    if (this.VideoView.Player != null)
                    {
                        
                        this.VideoView.Player.Stop();
                        
                        videoPlayerLoader.Visibility = Visibility.Visible;
                        this.VideoView.Player.OpenAsync(url);
                    }

                
            });
        });

SuRGeoNix · 2023-11-07T18:10:42Z

For some reason you dispose the previous player and you create a new one?

Just use OpenAsync (no Stop, no Dispose)

saman1832 · 2023-11-07T18:17:43Z

Just use OpenAsync (no Stop, no Dispose) this is causing UI freeze as well not able to play again.
when coming in timeout event status of player is playing. so if status is playing can we use openasync

SuRGeoNix · 2023-11-07T18:30:31Z

Just tried this code and worked fine for me

Player.VideoDemuxer.TimedOut += (o, e) =>
{
    Player.OpenAsync(@"...");
};

You need to debug your code, you shouldn't Dispose the Player (actually also the FlyleafHost) from what I can see

saman1832 · 2023-11-07T18:36:56Z

SuRGeoNix · 2023-11-07T18:41:22Z

Can you pause the debugger and see why it freezes (which thread/dead lock?)

saman1832 · 2023-11-07T18:44:41Z

when I am pausing the debugger and running then its working fine. But let me check again

saman1832 · 2023-11-07T18:57:29Z

I found this.

It starting after timeout but again getting stopped then paused.(see highleted one)

saman1832 · 2023-11-07T19:01:30Z

sometime
00.39.57.154 | Debug | [#1] [Demuxer: Main] Running -> Stopping

SuRGeoNix · 2023-11-07T19:17:38Z

I don't see something with these logs. Its normal to see the screamer to stop/finish. You need to identify the freeze, I suspect a binding or another event that you listen which hangs the UI.

saman1832 · 2023-11-07T19:18:43Z

now UI is not freezing but player is not opening

saman1832 · 2023-11-07T19:22:48Z

@SuRGeoNix please see the above cooment

SuRGeoNix · 2023-11-07T19:32:52Z

You dispose the FlyleafHost/Player/SwapChain. Not sure what you are doing as I cannot see your code.

saman1832 · 2023-11-27T12:18:19Z

@SuRGeoNix after applying
Player.VideoDemuxer.TimedOut += (o, e) =>
{
Player.OpenAsync(@"...");
};
the Playback opencomplete event is called after 5-7 mins.
You can have any rtsp url and switch off then on the camera the timeout will be hit then you can replicate easily.

saman1832 · 2023-11-27T13:07:25Z

AT 18.29 Player.VideoDemuxer.TimedOut += (o, e) =>
{
Player.OpenAsync(@"...");
}; this piece if code is executed.

SuRGeoNix · 2023-11-28T13:02:30Z

@saman1832 I cannot see your implementation. What I see from your logs is that you dispose the Demuxer and then trying to re-open it. That shouldn't be happening. You are doing something wrong with your code.
