Based on the hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.
Referring to fig. 3, fig. 3 is a flowchart illustrating steps of a video playing method according to an embodiment of the present invention, where the method is applied to a mobile terminal, and as shown in fig. 3, the method includes:
step 301, obtaining the reverse order coded data in the target video file.
In this step, the method obtains the reverse order encoded data in the target video file. In the embodiment of the invention, when or after the video is recorded, each frame of data in the recorded video is subjected to reverse order coding, and then the reverse order coded data and the forward order video data are stored in the video file together.
In the embodiment of the present invention, the method may determine whether the target video file supports reverse playback after receiving a playback operation for playing the target video file, and if the target video file supports reverse playback, the method obtains reverse encoded data in the target video file; and if the target video file does not support reverse-order playing, the method plays the target video file in a forward order.
In some embodiments of the present invention, after the method determines that the target video file supports reverse-order playing, the method may control the mobile terminal to provide a user interface for a user to select whether to play the target video file in a reverse order, and determine whether the mobile terminal receives a selection operation of selecting reverse-order playing by the user, and if the selection operation of selecting reverse-order playing by the user is received, the method obtains reverse-order encoded data in the target video file. In this case, if a selection operation that the user selects reverse-order playing is not received, the method plays the target video file in forward order.
The method for judging whether the target video file supports reverse order playing may be to judge whether the target video file includes reverse order encoded data or to judge whether a flag bit in the target video file is a preset value. For example, the method may define that the target video file supports reverse playing when the flag bit is "1", and the method may also define that the target video file supports reverse playing when the flag bit is "0", which is not specifically limited in this embodiment of the present invention.
In this step, the method obtains the reverse order encoded data in the target video file. In this embodiment of the present invention, the structure of the target video file may be as shown in fig. 4, that is, the target video file includes an original video file, reverse order encoded data, reverse order PTS data, and reverse order flag information. The method determines the position of the reverse order coded data in the target video file according to the reverse order marking information, and then obtains the reverse order coded data in the target video file according to the determined position. Specifically, the reverse order flag information may include reverse order encoded data position indication information indicating a position of reverse order encoded data in the target video file.
