Good morning,
in my application i am using version ffme 7.0.360-b1. My application allows the user to play various media files, which can be videos or gifs.
Every time the user plays a media, I stop and close the currently playing file

public void StopProgramAsync(bool close)
{
    Media.MediaEnded -= media_MediaEnded;
    if (t != null)
    {
        t.Stop();
    }
    StopAsync();

    if (close)
        CloseAsync();
}
public async void StopAsync()
{
    if (Media.Source != null)
        await Media.Stop();
}
public async void CloseAsync()
{
    await Media.Close();
}

and then open and play the new file.

if (File.Exists(file_media))
 {
     await Media.Open(new Uri(file_media));
TimeSpan start_time = TimeSpan.Zero;
if (Media_Prog.CutStart)
    start_time = TimeSpan.FromSeconds(Media_Prog.CutStartSeconds);
if (Media_Prog != null && Media_Prog.CutStart)
{
    start_time = TimeSpan.FromSeconds(Media_Prog.CutStartSeconds);
}

await Media.Seek(start_time);

await Media.Play();   
 if (Media_Prog.CutEnd && Media_Prog.CutEndSeconds > 0)
    {
        t = new System.Timers.Timer((Media_Prog.CutEndSeconds - Media_Prog.CutStartSeconds) * 1000);
        t.Elapsed += T_Elapsed;
        t.AutoReset = false;
        t.Start();
    }
    else if(Executions > 0)
    {
        Media.MediaEnded += media_MediaEnded;
    }
}

the problem is that sometines, especially when play a gif (in rarer cases also with videos), after play nothing is displayed.
I have capture the log in case when media is displayed correctly:

the engine seems to be in run, but when the media is not displayed there are log messages "VideoRenderer frame skipped at ..."

Do you have any suggestions on what it could be?
