Plugin for flutter.io/videoPlayer

[chunhunghan]

Can we have video player plug-in for Windows?

Thank you for your amazing work.

Yes WE can, but work needs to be made on: #102 #103.
Once those issues are resolved we could implement the plugin

[pchampio]

Progress on #102 has been made.
The Texture api is in beta release (use hover run -b '@beta' to test it)

The texture_tutorial has been updated with a video example.

What is left to do is to align ourself with the way the flutter.io/videoPlayer do things

[pchampio]

Looking for maintainer: A first implementation is available at: https://github.com/go-flutter-desktop/plugins/tree/master/video_player
A partial rewrite needs to be done, more info in the video_player's readme.

I've reimplemented the backend logic using gocv here https://github.com/Knights-of-the-Functional-Calculus/gfd-plugins/blob/master/video_player/cv.go

It's still showing memory leaks. I can't find any place where it might be leaking in my implementation nor in the flutter go embedder. Is there anyway we can renew interest in this subject? I'm not particularly great at leak hunting myself.

Edit: One thing I forgot to mention is that memstat appears to say that the leak isn't happening on the golang side, and I've made sure that my Mats are closed after usage. This could point to a leak in the flutter texture implementation, but I don't see it.

[pchampio]

@j4qfrost I'll take a look at this once I have more time.
It's awesome to see someone working on this subject!

[j4qfrost]

Bump. Is there anything I can do to get better at tracking down the leaks?

[pchampio]

I don't time at the moment, I'm very sorry but I can't help.
To track the memory leaks we can use valgrind, but it will interfere with the C-based engine.

I use this in Mac.But I got error like these:

(This is taking an unexpectedly long time.) ⢿go-flutter/plugins/video_player WARNING MethodCall to ' setLooping ' isn't supported by the Golang video_player

Can U help me?Thanks.
