Detailed Description

Todo:

Fix pause frame deinterlacing

Deinterlacing 'breaks' after certain stream changes (e.g. aspect ratio)

Scaling of some 1080 H.264 material (garbage line at bottom - presumably scaling from 1088 to 1080 - but only some files). Same effect on all VAAPI interop types.

Member Function Documentation

◆ GetVAAPITypes()

void MythVAAPIInterop::GetVAAPITypes ( MythRenderOpenGL Context,
MythInteropGPU::InteropMap Types 
)
static

Return a list of interops that are supported by the current render device.

DRM interop is the preferred option as it is copy free but requires EGL. DRM returns raw YUV frames which gives us full colourspace and deinterlacing control.

GLX Pixmap interop will copy the frame to an RGBA texture. VAAPI functionality is used for colourspace conversion and deinterlacing. It is not supported when EGL and/or Wayland are running.

GLX Copy is only available when GLX is running (no OpenGLES or Wayland) and, under the hood, performs the same Pixmap copy as GLXPixmap support plus an additional render to texture via a FramebufferObject. As it is less performant and less widely available than GLX Pixmap, it may be removed in the future.

Note
The returned list is in priority order (i.e. most preferable first).
