As requested in the contributors chat, here is an audio sample of the VideoStreamPlayer looping seamlessly (warning, might be loud). Audio being looped: Resulting output from Godot: Note that depending on CPU load and complexity of the audio, it still might crack. |

Part of a group of three PRs (#77856 #77857 #77858) that solve godotengine/godot-proposals#264.
This PR enables seamless looping in VideoStreamPlayer nodes with connecting the
on_finishedsignal to theplay()function. Currently doing this will result in a blank frame due to the fact that the internal processing trigger only fires again on the next frame, which means the draw call on the current frame will draw an empty texture. With this change the texture is already updated with the newly started playback, which renders the first frame to the texture instead of leaving it blank, eliminating the one frame flash of transparency of the previous implementation.Before (note the flash of background when the loop restarts):
before.mp4
After (no flash of background):
after.mp4
