Returns a list of adapters that are suitable to handle workload @p input_info. The list is sorted in priority order, with iGPU given the highest precedence.

This rule may change in the future. If the @p input_info pointer is NULL, the list of all available adapters will be returned.
|

@param[in] input_info Pointer to workload description. See mfxComponentInfo description for details.

@param[out] adapters Pointer to output description of all suitable adapters for input workload. See mfxAdaptersInfo description for details.

@brief
|
|
Returns list of adapters that are suitable to decode the input bitstream. The list is sorted in priority order, with iGPU given the highest precedence. This rule may change in the future. This function is a simplification of MFXQueryAdapters, because bitstream is a description of the workload itself.

|
|
@param[in] bitstream Pointer to bitstream with input data.
|
|
@param[in] codec_id Codec ID to determine the type of codec for the input bitstream.
|
|
@param[out] adapters Pointer to the output list of adapters. Memory should be allocated by user. See mfxAdaptersInfo description for details.
