Abstract

The invention discloses a video recording method and device based on a player. Among them, the video recording method based on the player includes: copying the data before decoding by the player for buffering, recording the first timestamp of the first frame of playback data, and recording the second timestamp of the first frame of playback data; when the user starts When recording, obtain the recording start time, calculate the first time stamp of the first recorded frame according to the recording start time, the first time stamp and the second time stamp corresponding to the playback data of the first frame, and obtain the first time stamp of the first recorded frame according to the first time stamp of the recorded first frame The corresponding first time stamp finds the corresponding data frame in the cached data and starts recording; when the user stops recording, obtain the recording end time and calculate the first time stamp of the last recorded frame, according to the corresponding first time stamp of the last recorded frame A timestamp to end the recording. The invention can realize precise recording of video.

Description

technical field [0001] The invention relates to video recording technology, in particular to a player-based video recording method and device. Background technique [0002] In recent years, with the rapid development of DVB CA (Digital Video Broadcasting Conditional Access, Digital Video Broadcasting Conditional Access) technology and the continuous advancement of the intelligentization of mobile consumer products, users are more concerned about the presentation form of programs and media while enjoying traditional media programs.
