* @brief Set bandwidth proportion for the data stream, video stream and download stream of high-speed channel.

* @details Self-defined bandwidth distribution mechanism allows that user can control bandwidth limitation
|
||
* freely. System multiplies total bandwidth limitation of the high-speed channel by a proportion of the corresponding stream to
|
||
* get realtime bandwidth limitation of the specified stream. Realtime bandwidth limitation of data and video stream can be
|
||
* gotten by PsdkDataTransmission_GetDataStreamState() and PsdkPayloadCamera_GetVideoStreamState() interfaces. Total
|
||
* bandwidth of the high-speed channel is determined by the environment in which the system located and loading of system. If
|
||
* user does not set bandwidth proportion for each stream, the default proportion is 33% (data stream), 33% (video
|
||
* stream) and 34% (download stream).
|
||
* @note The bandwidth proportion will be effective after a while, the max value is 1s. If you want use this interface, should calling
|
||
* PsdkPlatform_RegHalNetworkHandler interface firstly, otherwise this interface will not work.
|
||
* @param bandwidthProportion: bandwidth proportion of each stream of high-speed channel. The Sum of bandwidth proportion
|
||
* must equal 100.

* @return Execution result.
