// Specifies the type of shared image format used by media video
// encoder/decoder. Currently, we have (1) one shared image (and texture)
// created for single planar formats eg. RGBA (2) multiple shared images created
// for multiplanar formats eg. P010, NV12 with one shared image for each plane
// eg. Y and UV passing singleplanar SharedImageFormats (kR_8, kRG_88, kR_16,
// etc.) and (3) one shared image created for multiplanar formats passing in
// legacy multiplanar SharedImageFormats that are used with external sampler.
// As we roll out usage of MultiPlaneFormat, this enum helps with
// differentiating between 3 cases: (1) SinglePlaneFormat/LegacyMultiPlaneFormat
// (2) MultiPlaneFormat without external sampler, and (3) MultiPlaneFormat with
// external sampler. NOTE: This enum is interim until all clients are converted
// to use MultiPlaneFormat for all multiplanar use cases; then it will be
// replaced with bool for external sampler usage.
