Videotexture Playback stuttering

[wirmachenbunt]

is there any way to make videotexture playback smooth ? right now it's not really usable this way.

and can also be seen in the demo patch with the clouds video

example can't be opened in editor, so can't really look at it

the example is a stop motion video, it is not fluid, yes its a bad example, i dont have anything better with a license we can use

what codec is this video ? is seems to be transparent, thats not a standard feature of browser videos, so thats probably slow ?

the title was misleading, its a standard mp4 file

when playing the video as videoelement and not as texture, it plays smooth

this is 60fps 1080p it plays fine for me

not the best video to see if it stutters but this stutters as well, on multiple PC's with big GPU's

on the mac with its high refresh rate, its probably not as visible compared to a 60hz display. comparing your video in a videoplayer software to the playback as a texture in cables, the difference is very much visible

i dont know

maybe its the same as this discussion:

mrdoob/three.js#13379
https://web.dev/articles/requestvideoframecallback-rvfc

that solution does not work in ff

[pandrr]

on dev.cables.gl the op now uses requestVideoFrameCallback if available and ignores the input fps number (output port "auto fps" is then true)

please check if this gives you better results.
