Audio playback issues with fast forward

[Aztorius]

Hi, i'm running Fedora 37 (KDE Wayland + Pipewire + mesa with RX 6700) with Bino 2.0 manually compiled (thanks for this great 3D video software).

I'm playing an MKV file (3D Half Side By Side) of 13GB :

When using multiple times the Right arrow to move forward (or page up), the sound is desynchronising and then totally mute. Then, if I try to change Audio track Bino completely freeze. Also the sound briefly spikes at the start of the video (really spikes).

Thanks.

Since version 2.0, Bino does not implement its own decoding, seeking or audio/video synchronization anymore. It relies on Qt Multimedia instead. So this is most probably an issue with Qt Multimedia; either its implementation or its backend (GStreamer). Maybe adding seeking support to the Qt Media Player example via QMediaPlayer::setPosition() could help you track down the problem. There's nothing we can do to fix this in Bino.

I've just compiled the Qt Media Player example. Same issues (without the audio spike at the beginning like Bino). When seeking further in the file a first time it is fine, but the second time audio is muted, then the app freeze if I try to change audio track. Same issues with different video files. No useful logs.

That should be enough material to write a Qt bug report.

Closing this since it is a Qt problem, not a Bino problem.
