[0054] In the disclosed embodiment, the watermark added by the system to the first target video can be understood as a processing marker, that is, the watermark indicates that the video has been processed by the system and does not need to be processed again by the Android side. The watermark can be a time watermark as described above, etc. The specific form of the watermark is not limited in this disclosure.

[0075] In the embodiment of the present disclosure, the electronic device may send the encoded data to the Android side through the system side.

[0076] Specifically, after the electronic device obtains the encoded data through the system side, it can send the encoded data to the Android side, for example, using the TCP protocol to send the encoded data to the Android side.

[0083] like Figure 2As shown, for example, when the current vehicle is driving, the video of the driving process can generally be acquired through the camera of the driving recorder in the vehicle. When acquiring the video, the electronic device first calls to open the camera interface through the Android side (Android), then assembles the camera parameters of the camera, and sends the camera parameters to the system side (QNX) through the TCP protocol. The system side (QNX) adjusts the camera parameters according to the camera parameters, and controls the camera to acquire the first target video. Then, the system side adds a watermark to the first target video to obtain the second target video, and then encodes the second target video to obtain corresponding encoded data in H265 format. The electronic device sends the encoded data to the Android side (Android) through the system side (QNX) through the TCP protocol, and saves the received encoded data through the Android side (Android) to obtain the corresponding final video in MP4 format.
