VideoStreamPlayer stops and cracking sound

[LordNeo17]

Tested versions

v4.2.1.stable.official [b09f793]

System information

Godot v4.2.1.stable - Windows 10.0.22631 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 4070 (NVIDIA; 31.0.15.5152) - 13th Gen Intel(R) Core(TM) i5-13400F (16 Threads)

Issue description

When playing the video in Godot, it just pauses briefly at one point and otherwise you can hear audio crackling throughout the entire video. Am I doing something wrong or is this a bug in the engine? Outside the engine, the video works fine.

VideoStreamPlayer.1.mp4

Steps to reproduce

• Add a VideoStreamPlayer
• Put the video in the stream property

Probably related to #21568 and #66331. (duplicate?)

Godot's Theora decoding implementation has been confirmed to have a glitchy audio whenever the image doesn't update.

I believe this issue and those two above are the same thing. Have you tried to encode the video with a keyframe interval of 1 (ffmpeg -g:v 1)? This ensures each frame in the video is a different one while massively increasing file size, but it's just for testing purposes.

If the issue doesn't happen with the resulting video, then yes, it's the same.

I just encountered this bug. the fix from @DeeJayLSP to add -g:v 1 worked. It didn't increase file size at all really for me, since my video is very small.

Consolidating in #66331 which is about the same underlying bug.
