[Discussion] About video parsing/playback as texture.

[adfriz]

as title said...

I have done implementing video playback using library, specifically libmpv with their dll file.

although it works and run well locally (only tested with .mp4 in windows), I'm still unsure how this play well in terms of license.

AFAIK, we could just bring the dll as is ? and write the license in the readme as usual?

Note: the code still on my PC maybe i will push it as a PR like always if all clear...

@leezer3 what do you think?

the object written as usual, using load command.

[MeshBuilder]
Vertex 0.0000, 0.6000, -1.0000, 1.0000, 0.0000, 0.0000
Vertex 0.0000, 0.6000, 1.0000, 1.0000, 0.0000, 0.0000
Vertex 0.0000, -0.6000, 1.0000, 1.0000, 0.0000, 0.0000

If the license can be cleared and implemented, it would be great if it could be played on the interior of the exterior view.

I understand that current animated GIFs are designed for around 30 seconds. It would be great if the playback time could be unlimited.

There are people who use it this way, and it would be great to be able to display various movies on displays in trains, stations, and advertisements to create digital signage.

[adfriz]

the duration of the video will not get cut, you may try it yourself by following the instructions in #1333

well... it can be used anywhere, i tried make this as basic as possible. you just need an object like signage and separate the [meshbuilder] for the video part.

let say an signage-object.b3d

[meshbuilder]
vertex......
Face....
Load yourtexture.jpg
Coordinates....

[meshbuilder]
vertex......
Face....
Load myvideo.mp4
Coordinates....

This should works.

Thank you show me how to use for testing.
If it could be incorporated as an object section within the animated objects, I think it would look like the Crosshatch video. Is that possible?

[adfriz]

should be possible.

you may test it with simple animated file first.

maybe make the object spin with RotateYFunction = sin[time/5] ?
