aclError aclvencSetChannelDescMaxBitRate(aclvencChannelDesc *channelDesc, uint32_t maxBitRate)

Python Function

ret = acl.media.venc_set_channel_desc_max_bit_rate(venc_channel_desc, max_bit_rate)

Parameters

Parameter	Description
venc_channel_desc	Int, pointer address of the description of a video encoding channel. Call acl.media.venc_create_channel_desc to create data of the aclvencChannelDesc type in advance.
max_bit_rate	Int, output bit rate (kbps) For the Atlas 200I/500 A2 inference product, the value range is [2, 614400]. The default value is 2000. If it is set to 0, the default value 2000 is used. For the Atlas inference product, the value range is [2, 614400]. The default value is 2000. If it is set to 0, the default value 2000 is used.
