[Request] Expose Vulkan and vo_dmabuf_wayland in libmpv (for third-party clients)
Hello there,
I've been using mpc-qt as the client/player (using libmpv) for viewing content. I inquired with its author if it was possible to enable Vulkan & vo_dmabuf_wayland support and he replied with the following. To summarize, if libmpv exposed these features directly then it may be possible to enable support in mpc-qt without it being complicated for the project.
Expected behavior of the wanted feature
If Wayland and vo_dmabuf_wayland are exposed via libmpv, third-party clients can incorporate the features much easier.
Alternative behavior of the wanted feature
I'm not sure what that would be but @cmdrkotori, or you wonderful devs, would have a better idea about this than I. :)
Being able to access dmabufs would be useful for integrating with toolkit like GTK, which has recently gained support for video passthrough on Wayland.
Is there any update from the team on this, or any specific blockers preventing such a feature?
There is no way for this to work other than writing a totally new api that uses subsurfaces. It's not a trivial change and even then it would require any client to write a ton of new wayland-specific code. So probably not happening anytime soon.
To be clear, you can use vo_dmabuf_wayland in libmpv like any other VO but there is no render API or embedding support. The render API is still opengl-only.

Ah, alright. Thank you for the info! I'll have to figure something else out then.
@Dudemanguy mentioned libwlembed as a potential solution in https://github.com/mpv-player/mpv/pull/12627#issuecomment-3335166707.
