Member Data Documentation

mirror_flags

uint32_t VAProcPipelineCaps::mirror_flags

Mirroring flags.

For each mirroring direction supported by the underlying hardware, the corresponding bit is set in mirror_flags. See "Mirroring directions" for a description of mirroring directions.

rotation_flags

uint32_t VAProcPipelineCaps::rotation_flags

Rotation flags.

For each rotation angle supported by the underlying hardware, the corresponding bit is set in rotation_flags. See "Rotation angles" for a description of rotation angles.

A value of 0 means the underlying hardware does not support any rotation. Otherwise, a check for a specific rotation angle can be performed as follows:

VAProcPipelineCaps pipeline_caps;
...
vaQueryVideoProcPipelineCaps(va_dpy, vpp_ctx,
    filter_bufs, num_filter_bufs,
    &pipeline_caps
);
...
if (pipeline_caps.rotation_flags & (1 << VA_ROTATION_xxx)) {
    // Clockwise rotation by xxx degrees is supported
    ...
}
