Embodiment 1
[0051] figure 1 It shows a flow chart of an improved method for dual-channel video recording provided by the first embodiment of the present invention, which is described in detail as follows:
[0052] Step S11, create an encoding instance of channel 1, and set encoding attributes in the encoding instance of channel 1.
[0053] In this embodiment, the encoding attribute includes encoding type, encoding size, encoding mode, whether to perform code rate control, and the like. Among them, the encoding type can be any one of H.264, MJPEG, H.263, and MPEG4, and the encoding size can be any one of QCIF, CIF, VGA, D1, 720P, and 1080P. Of course, it can also be set Other encoding types and encoding sizes are not limited here. Wherein, the encoding method refers to which encoding method is used for a certain encoding type, for example, for H.264, cabac encoding, cavlc encoding, etc. may be used.
[0054] In step S12, an encoding instance of channel 2 is created, and an encoding attr...

Abstract
The invention is suitable for the field of videorecording monitoring, and particularly relates to a method and device for improving double-way videorecording and a monitor unit. The method includes the steps that (1) a coding instance of a first channel is built, and a coding attribute is set; (2) a coding instance of a second channel is built, and a coding attribute is set; (3) according to the set coding attribute of the first channel, coding parameters which are assigned to a register are determined; (4) according to the set coding attribute of the second channel, the coding parameters which are assigned to the register are determined; (5) after the register is successfully assigned, codes of current frames are started, whether the current frame of the first channel and the current frame of the second channel are coded or not is judged, if yes, the step (6) is executed, and if not, the step (7) is executed; (6) codes of next frames are started, and coded current code streams are written into a file; (7) whether the current frames are coded or not continues to be judged; (8) the operation from the step (3) to the step (7) is repeatedly executed until videorecording is finished. According to the method and device for improving double-way videorecording and the monitor unit, coding efficiency can be improved.
Description
technical field [0001] The invention belongs to the field of video monitoring, and in particular relates to an improved method, device and monitor for two-way video recording. Background technique [0002] At present, monitoring technology has developed from single-channel monitoring to multi-channel monitoring. Multi-channel monitoring technology has many advantages. According to user needs and different application scenarios, video recordings with various resolutions and encoding methods can be formulated. With the development of monitoring technology, multi-channel monitoring technology is also changing with each passing day. [0003] The frame rate of single-channel encoding is generally 30 frames per second, that is, the fps of single-channel encoding is 30. Correspondingly, the fps of dual-channel encoding will be 60, that is, dual-channel encoding requires higher encoding efficiency. It can be seen that improving the coding efficiency of the two-way coding can better...
