Expected Behavior

I expect the full audio of the file to be played out rather than cut early

Current Behavior

When playing the transition the audio will be cut abruptly instead of continuing

Steps to Reproduce

Create 2 scenes
Create a 4 second stinger transition with audio
Swap between the two scenes ...

Anything else we should know?

The File Type is AVI The Stinger file is 4 seconds The Transition Point is 1.5 seconds The Audio is being cut around 2.5 seconds

Please provide the stinger file you're testing with.

Also, could you try this with the "Preload Video to RAM" option enabled? That should rule out decoding performance issues.

@gxalpha Thanks, I have tested the Preload Video to RAM and the issue is still occurring, however as far as the stinger file goes, its a custom commission for a customer graphic and audio (art of their model that has not been released yet) that I would rather not post publicly without their permission.

I reached out to someone on the discord and they are going to share the file with you internally

@Baylem thank you, I received the file. I was able to reproduce the problem.

Logging my initial findings:

It plays back fine in VLC
In an OBS Media Source, it plays back fully, but the toolbar goes into negative time left at the end
At the time where the media source would reach 0 (and then go into negative time), it cuts out when using it as a transition
When playing back, the log OBS complains about Timestamp for source '[source name]' jumped [...].

Does the same issue occur when the AVI is converted to VP9 or ProRes? If it doesn't that might suggest that either the timecodes in the AVI are broken or our handling of the timecodes is.

@gxalpha Would you be able to test what @PatTheMav suggested or do I need to figure it out and reply? (I'm not familiar with audio files/encoding is why I'm asking, I apologize)
