47// change how the component receives the native buffers. If store-metadata-mode

390// to video encoders and decoders when the
391// 'OMX.google.android.index.describeColorAspects' extension is given.
392//
393// Video encoders: the framework uses OMX_SetConfig to specify color aspects
394// of the coded video before the component transitions to idle state.
395//
396// Video decoders: the framework uses OMX_SetConfig to specify color aspects
397// of the coded video parsed from the container before the component transitions
398// to idle state. If the bitstream contains color information, the component should
399// update the appropriate color aspects - unless the bitstream contains the
400// "unspecified" value. For "reserved" values, the component should set the aspect
401// to "Other".
402//
403// The framework subsequently uses OMX_GetConfig to get any updates of the
404// color aspects from the decoder. If the color aspects change at any time
405// during the processing of the stream, the component shall signal a
406// OMX_EventPortSettingsChanged event with data2 set to the extension index
407// (or OMX_IndexConfigCommonOutputCrop, as it is handled identically). Component
408// shall not signal a separate event purely for color aspect change, if it occurs
409// together with a port definition (e.g. size) or crop change.
410//
411// NOTE: this structure is expected to grow in the future if new color aspects are
412// added to codec bitstreams. OMX component should not require a specific nSize
413// though could verify that nSize is at least the size of the structure at the
414// time of implementation. All new fields will be added at the end of the structure
415// ensuring backward compatibility.
