This message should always be the last streaming message received by a channel.

If all the input buffers sent with DVM_STREAM_ADDBUFFER haven't been returned to the application, your driver should fail the message. Client applications should send DVM_STREAM_RESET to mark all pending buffers as done prior to sending DVM_STREAM_FINI.

For VIDEO_EXTERNALIN channels, this message halts capturing of data to the frame buffer.

For VIDEO_EXTERNALOUT channels that support overlay, this message disables the overlay video.
