Hello!
is it possible to load a video files(specifically, mpg and avi files) and play it?
tried to use VideoPlayer before, but I cant find out how to use it.

I think Godot can play Theora videos (.ogv) but I never tried it yet.

Godot can currently only decode Ogg Theora (file extension: .ogg or .ogv). Take a look at the VideoPlayer class.

You can encode videos for Ogg Theora using tools like FFmpeg.

Note that there is also OS.native-video-play() that should play mp4 (and some others) on Android and iPad devices.

are there any examples using the OS.native-video-play() function? I can not get this to work either?

If you only want to play fullscreen video with sound (and eventually subtitles), you can include ffplay from ffmpeg into a sub directory of your project, and run it using the OS.execute() function.

extends Control

var pid = null;

func _ready(): #{
	pass
#}
	
func play(videopath): #{
	pid = OS.execute("bin/ffplay",["-autoexit", "-exitonkeydown", "-exitonmousedown", "-fs", videopath ],true);	
#}

func _on_Play_pressed(): play("video/test.mp4");

According to my test, under Windows, specifying the .exe extension is not mandatory. This mean this code should work on all platforms.

Thanks, this is a great workaround.

Does this still work? I think I have everything configured correctly, but still get the errors below?

extends Control

var pid = null;

func _ready(): #{
	pass
#}

func play(videopath): #{
	pid = OS.execute("res://bin/ffplay",["-autoexit", "-exitonkeydown", "-exitonmousedown", "-fs", videopath ],true); 
#}

func _on_Play_pressed(): play("res://assets/videos/P1010293.MP4");

Error from Godot Console:

Does it work for you in the editor?

SteveSmith | 2022-10-20 07:11

I didn’t get any errors before running the program, if that is what you are asking? It was not until after running it and hitting the connected _on_Play_pressed button.

It’s just that the error mentions Javascript, so I wondered if it was only failing after exporting.

SteveSmith | 2022-10-20 07:38

Yes, that is the error I get after the web export.

But does it work when running in the editor?

SteveSmith | 2022-10-20 08:07

I don’t get any video to display, or play, in the editor or otherwise.
