[DimaKiva]

Operating system or device, Godot version, GPU Model and driver (if graphics related):
Ubuntu 16.04, Godot 3.0 beta 1

Steps to reproduce:

What kind of VideoStream are you playing? This bug report doesn't provide enough information, please try to be more specific.

• VideoPlayer::set_stream_position calls VideoStreamPlayback::seek: https://github.com/godotengine/godot/blob/86ed07c/scene/gui/video_player.cpp#L378
• It's a virtual method which has to be defined in each VideoStreamPlayback implementation: https://github.com/godotengine/godot/blob/03a0805/scene/resources/video_stream.h#L59
• We currently support Theora and WebM, both of which have a non-implemented seek method. Implementing it for both formats should solve this issue.

  • https://github.com/godotengine/godot/blob/13c2ff9/modules/webm/video_stream_webm.cpp#L222-L225

i am just looking around to see how to add seek to ogg.

looks pretty complicated

i am debating whether or not to try to fix it since i kinda want to understand how ogg works

@hungrymonkey would it be easier to implement for webm?

[hungrymonkey]

@blurymind probably somewhat the same difficulty.

you have to seek to find keyframes. The code doesnt really separate grabbing frames and finding the keyframe.

I would like to give this problem a push.
It would be really great if the seek function could be implemented.
Godot 3.1 ?

godot 3.1.1 same bug

[hungrymonkey]

I do not think libsimplewebm supports seeking.
