I find the performance of WebChimera is half of fbvlc(CPU loading) about webchimera

[RSATom]

I didn't test it for perfomance yet, but there are at least one place where optimization could be made:
In QmlVlcVideoOutput.cpp RGB32 used as default pixel format, but most of videos use I420 pixel format. Furthermore I420, is more suitable for OpenGL as I know. So I plan to use I420 instead of RGB32 in the future, to increase performance.
Another possible reason is that for video output I use QtMultimedia's video surface, and I don't know how efficient it is.
And the biggest problem - I limited in free time, and now I am working on FBVLC for Mac. I hope to return to WebChimera development till end of Junuary.

Anyway you comment is very useful, Thanks!

Thanks, Could you help share a cool qml you used ?

[RSATom]

btw, when you talking about fbvlc's performance, do you mean windowless or windowed version?
Fbvlc's windowless mode should be slower than WebChimera. Since fbvlc use vmem (i.e. decode to memory), and then draw on hwnd with GDI. WebChimera use vmem too, but use hardware accelerated OpenGL (or DirectX in Qt version with Angle Lib) drawing.
In turn, WebChimera should be slower than windowed FBVLC, since then libvlc use OpenGL or DirectX for rendering directly.

I use windows mode for FBVLC

Sorry, didn't understand what you mean. If you are talking about qml used in WebChimera - it's in available: default.qml. But it's not cool, I plan to find real designer who, I hope, will draw really cool UI

[RSATom]

Windowed FBVLC has very big disadvantage - it's not allow place custom UI items over it via HTML. But it has very big advantage in performance.
Windowless FBVLC can be overlayed by html items, but it has very poor performance. That's why I started WebChimera project - it uses hardware accelerated draw via Qt Quick, and allow to add custom Ui items via Qml.

[xsmart]

Yes, i mean the qml used in WebChimera. not the default.qml, If you have a my_cool_ui.qml?

[RSATom]

no, I haven't it ;) It's only in future plans.

WebChimera was born less then month ago, so there are a lot of work still...

[xsmart]

Waiting for you cool UI ...

[RSATom]

You can try do it by yourself, that's the main Idea of WebChimera. Qml is reasonable simple.

[RSATom]

WebChimera 0.1.2 was switched to I420 pixel format internally...

Waiting for you cool UI ...

It seems cool UI now available: http://jaruba.github.io/WebchimeraGUI
