Function: vdec_destroy_channel

C Prototype	*aclError aclvdecDestroyChannel(aclvdecChannelDesc channelDesc)**
Python Function	ret = acl.media.vdec_destroy_channel(vdec_channel_desc)
Function Usage	Destroys a video processing channel created by calling acl.media.vdec_create_channel.
Input Description	vdec_channel_desc: int, pointer address of the channel description. It must be the same as the vdec_channel_desc argument passed to the acl.media.vdec_create_channel call.
Return Value	ret: int, error code. 0 indicates success. Other values indicate failure.
Restrictions	The channel is destroyed after the transmitted frames are decoded and the callback function is handled. acl.media.vdec_destroy_channel encapsulates acl.rt.unsubscribe_report to unsubscribe from a thread (callback function in the stream is no longer processed by the specified thread), and acl.rt.destroy_stream to destroy a stream. To implement the VDEC function, acl.rt.unsubscribe_report and acl.rt.destroy_stream do not need to be called separately. If acl.media.vdec_destroy_channel_desc has been called to destroy the channel description before the acl.media.vdec_destroy_channel call, an error is reported.
Reference	For details about the API call sequence and example, see Media Data Processing V1.
