[suggestion] Video support? about canvas HOT 4 CLOSED

Hi,
that would certainly be great if DrawImage could also draw a video frame. I don't want to add a dependency to a video library, but what would solve it quite nicely is if DrawImage could also take an interface of some kind. Do you happen to know any decent video libraries? I played around with a Go binding for ffmpeg once, but couldn't get it to work.

@tfriedel6 did you check out https://github.com/3d0c/gmf ? ffmpeg bindings, seems to be still maintened, haven't tested it though. Found it on awesome-go (https://github.com/avelino/awesome-go#video)

@tfriedel6 hey, any news? would be cool if this was implemented, as this is vital for a project I'm working on weekends..

Hi! I didn't have much time last week, but I gave it a shot just now to see what could be done. The best I could come up with was to add a Replace function to the Image type, so that you can replace the image every frame and avoid allocating a new texture. I also tried the gmf library you linked, which seems to work better than any I tried before, but I don't know enough to be able to use it correctly.

Anyway, here is a gist that is just a modification of one of their examples and seems to be able to basically display a video, though it does not respect the frame rate. Not sure how to do that.
