Obtains the VUI configurations of an H.264 encoding channel.

The Atlas 200/300/500 Inference Product does not support this API.

The Atlas Training Series Product does not support this API.

chn: int, encoding channel ID.

h264_vui: dict, VUI attributes of an H.264 encoding channel. For details, see hi_venc_h264_vui.

ret: int, error code.

• 0 indicates success.
• Other values: failure. For details, see VENC/JPEGE Return Codes.

• This API is used to obtain the VUI configurations of an H.264 encoding channel.

• This API must be called after an encoding channel is created and before the channel is destroyed.

• It is recommended that this API be called after an encoding channel is created and before encoding is started, to reduce the number of the API calls during encoding.
• It is recommended that this API be called only in an H.264 encoding channel.
