53 ``V4L2_DEC_CMD_START_MUTE_AUDIO`` flag instead.
55 This ioctl call asks the audio device to mute the stream that is
56 currently being played.
62 On success 0 is returned, on error -1 and the ``errno`` variable is set
63 appropriately. The generic error codes are described at the
64 :ref:`Generic Error Codes <gen-errors>` chapter.
