/**
 * pixelformat_for_profile - map a VA-API VAProfile to its V4L2 OUTPUT-side
 *                            pixel format FOURCC.
 *
 * @profile: VAProfile enum value as passed to vaCreateConfig.
 *
 * Returns the V4L2_PIX_FMT_* constant that the V4L2 device's OUTPUT_MPLANE
 * (bitstream-input) queue should be set to in order for the kernel
 * stateless decoder to dispatch to the right codec_mode. Used at
 * RequestCreateConfig to populate object_config->pixelformat, and read
 * from there at RequestCreateContext when committing the OUTPUT format
 * to the V4L2 device.
 *
 * Returns 0 for an unhandled profile; caller is expected to either
 * fall back to a safe default or refuse to proceed.
