Unhandled Exception in AudioDecoder when seeking multiple times

[getsolved]

When seeking in a video multiple times in a short time period, sometimes an unhandled exception is thrown in AudioDecoder class. The app crashes at this moment. Why isn't there any exception handling?

The screenshot is from a webm file playing, with other formats the same situation as well.

Any suggestions?

This seems either a broken file or an FFmpeg bug. Does this happen with v3.7 (ffmpeg v5) and v3.8 (ffmpeg v6)?
Can you provide a file to reproduce it?

Sorry for my late reply.

You can use any video that is longer than your provided sample. Tested it with different source videos (YT downloads, mkv files, mp4 files, 1 minute videos, 1 hour videos...). When you open a video file in the FlyLeaf Media Player (same behaviour using FlyLeaf Media Player Control in my WPF app) and seek many times (means click ony many different positions on the time progress bar) within a second, the app crashes, giving different exceptions: sometimes detecting audio problems, sometimes finding no frame for the current timestamp. Other behaviour: the play button does not work any more; the video seems to play, but no frame is changed, the current frame is freezed and pause, start, stop does not change anything; you have to restart the app.

Couldn't find out the reason. Very disappoiting to finally have a working WPF app but the embedded media player crashes regularly.

Perhaps you can easily detect the source making these problems. I am kind of helpless.

Additional information: using FlyLeafLib 3.8.2, Flyleaf.FFmpeg 7.1.0

All videos are working correctly with "fast seeking" like described above in PotPlayer and VLC Media Player.

@getsolved Still can't reproduce it. Do you use Flyleaf's FFmpeg libraries or custom build? This is might also related with your hardware. I cannot help if I will not reproduce it.
