C++ (Cpp) handle_preemption Examples

Example #1

File: gl_hwdec_vdpau.c Project: asdlei00/mpv

static int map_image(struct gl_hwdec *hw, struct mp_image *hw_image,
                     GLuint *out_textures)
{
    struct priv *p = hw->priv;
    GL *gl = hw->mpgl->gl;

    assert(hw_image && hw_image->imgfmt == IMGFMT_VDPAU);

    if (handle_preemption(hw) < 0)
        return -1;

    if (!p->vdpgl_surface)
        return -1;

    mp_vdpau_mixer_render(p->mixer, NULL, p->vdp_surface, NULL, hw_image, NULL);

    gl->VDPAUMapSurfacesNV(1, &p->vdpgl_surface);
    out_textures[0] = p->gl_texture;
    return 0;
}

Example #2

File: vdpau.c Project: CrimsonVoid/mpv

// Check whether vdpau initialization and preemption status is ok and we can
// proceed normally.
bool mp_vdpau_status_ok(struct mp_vdpau_ctx *ctx)
{
    return handle_preemption(ctx) >= 0;
}
