Returns

0: success
Other values: failure. For details, see VDEC/JPEGD Return Codes.

Restrictions

Ensure that a channel has been created. Otherwise, the error code HI_ERR_VDEC_UNEXIST is returned.
Ensure that the channel has stopped receiving streams. Otherwise, the error code HI_ERR_VDEC_NOT_PERM is returned.
