C Prototype

        
             aclError aclvencDestroyChannel(aclvencChannelDesc *channelDesc)

Python Function

        
             ret = acl.media.venc_destroy_channel(venc_channel_desc)

Parameter	Description
venc_channel_desc	Int, channel description. It must be the same as the channelDesc argument passed to the acl.media.venc_create_channel call.

Return Value	Description
ret	Int, error code. 0 on success; else, failure.

The channel is destroyed after the callback function is handled.
If the acl.media.venc_destroy_channel_desc API has been called to destroy the channel description before acl.media.venc_destroy_channel is called to destroy the channel, an error is reported when acl.media.venc_destroy_channel is called.

For details about the API call sequence and examples, see Media Data Processing V1.
