Cross-platform video sink on top of SDL

[Yuriy Volkov]

Thank you for your reply, Nicolas.

What would it take to integrate well in an existing app from the GStreamer
perspective? Are there any standard approach which applications tend to
follow?

Isn't it possible to abstract away SDL rendering method and match
colorspace with https://wiki.libsdl.org/SDL_CreateTexture ?

Best,
Yuri
