When the capacity of file corresponding to first interface and file corresponding to the second interface reaches to may store in terminal
Large Copacity, and when there is the video data not encoded by encoder, terminal is by the file according to first interface and the second correspondence
The sequencing of storage carries out deleting the file stored at first, to store the video data of the output of encoder.
With terminal storage space as 1G, the file that first interface is corresponding is the first file and the 3rd file, the second interface pair
The file answered is the second file, and the sequencing of the storage of file is the first file, as a example by the second file and the 3rd file, when
First file, the total capacity of the second file and the 3rd file has reached 1G, and terminal still suffers from needing being encoded by encoder
Video data, the most now terminal carries out deleting the file stored at first, by first interface pair according to the sequencing that file stores
File the first file answered is deleted, and to store the video data of the output of encoder, also needs to store the output of encoder afterwards
Video data and terminal in there is no enough memory spaces, then the second file is deleted by the sequencing stored according to file
