Embodiment Construction
[0054] Embodiments of the present invention provide a method, device, and terminal device for realizing seamless video recording at the native layer of the Android system, so as to solve the problem of missed seconds commonly existing in existing continuous video recording solutions.
[0055] The inventor found in the research process that in the prior art, in the local framework layer of the Android system, that is, the native layer, the continuous video recording is generally realized through the video interface StagefrightRecorder; specifically, the StagefrightRecorder controls an encoder and an encapsulator for cyclic creation And release, each time the encoder and wrapper are created, the encoding and encapsulation of audio and video data within a predetermined period of time is completed, a video file is obtained, and then the wrapper is released and recreated, thus starting to process the next time period Encoding and encapsulation of audio and video data to obtain the n...

The embodiment of the invention provides a method and apparatus for sealing seamless video recording on a native layer, and a terminal device. Original audio and video data collected by an audio and video collection device are encoded through an encoder in a video recording interface StagefrightRecorder to obtain audio and video encoded data, a package operation of the audio and video encoded data is executed by two packaging devices alternately, before one packaging device stops a package process, the other packaging device is started in advance, and the package operation is started, therefore two adjacent video recording files have a superposed part, in this way, the second leakage phenomenon can be completely eliminated, and seamless video recording is truly realized. Meanwhile, the method and apparatus provided by the embodiment of the invention are realized on the native layer, therefore the original audio and video data collected by the audio and video collection device can be directly obtained and then are encoded and packaged to ensure that the frame rate of the finally obtained video recording file is not reduced, and the video recording quality is improved.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of video recording, and in particular to a method, device and terminal equipment for realizing seamless video recording at the native layer of the Android system. Background technique [0002] In production and life, continuous video recording is required in many occasions, such as surveillance video on the street, surveillance video in the production workshop, driving record on the car, etc. Since the longer the recording time, the larger the recorded video file, it is impossible to save all the recorded videos in one file during the continuous recording process. It is necessary to segment the recording according to the time, that is, to produce a video file every time a period of recording is recorded. . For example, if the recording time of each video file is set to 5 minutes in advance, and the recording starts at 9:00:00, the following video files should be obtained in sequenc...
