Abstract

The invention discloses a video recording method and device based on a player. The video recording method based on the player comprises the following steps: copying data before decoding of the playerfor caching, recording a first timestamp of a first frame of playing data, and recording a second timestamp of the first frame of playing data; when a user starts recording, acquiring recording starttime, carrying calculation according to the recording start time and the first timestamp and the second timestamp corresponding to the first frame playing data so as to obtain the first timestamp of arecorded first frame, and finding out a corresponding data frame in the cached data according to the first timestamp corresponding to the recorded first frame to start recording; and when the user stops recording, acquiring recording ending time, carrying out calculation to obtain a first timestamp of the last recorded frame, and ending recording according to the first timestamp corresponding tothe last recorded frame. According to the invention, accurate recording of videos can be realized.

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. The diversification of playback functions is also constantly improving. For example, users hope to add PVR (Personal video recorder, personal video recorder) to the player, so that users can enjoy different experiences brought by traditional DVB live programs on various mobile terminals, allowing users While enjoying the pleasure brought by the direct program, you can also record the wonderful moments of the reserved program, realizing the humanize...
