Problems solved by technology

[0008] However, in the process of implementing the present invention, the inventor found that the above-mentioned scheme may also involve encryption issues when performing in-depth protocol analysis, resulting in that the added fields cannot be decrypted and obtained. For example, the entire load of RTP may be encrypted, so that May result in the inability to measure the GOP value

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0027] Such as figure 1 As shown, it is a schematic flow chart of the video stream performance measurement method in the embodiment of the present invention, and the flow includes:

[0028] 101. Obtain bit amount information of each video frame in the video stream from the video stream. For example, each video frame is obtained according to the boundary information of the video frame detected from the video stream, and its bit amount information is obtained according to each video frame.

[0029] 102. According to the bit amount information of each video frame and the preset matching strategy, perform matching detection on the assumed GOP value within the value rang...

Abstract

The invention discloses a device and a method for measuring video flow performance and a packet loss method. The method for measuring video flow performance comprises the following steps: acquiring bit quantity information of all video frames in the video flow; carrying out matching detection on the assumed Group of Picture (GOP) value within the GOP value span of the video flow according to the bit quantity information of the video frames and the preset matching plan; and if the matching is successful, the assumed GOP value is the GOP value corresponding to the video flow. In the scheme, theGOP value is acquired by carrying out the matching detection according to the bit quantity information of the video frames without analyzing all the frames so as to avoid decoding, excessive dependence on the transport protocol, excessive dependence on the deep protocol analysis and the problems of enciphering, copyright and the like. Thus, the measuring equipment arranged in the network can detect the GOP value of the video sequence at low cost.

Description

technical field [0001] The invention relates to the field of information transmission, in particular to a video stream performance measurement method, device and system. Background technique [0002] When providing video services in a network with Internet Protocol (IP) as the core, in order to ensure the performance of the provided video services, in addition to adopting some internal measures to ensure the service quality, it is also necessary to monitor the video streams of the video services from the outside. performance is measured and monitored in real time. [0003] When video stream performance measurement is performed at the application layer, the measurement object may be a Group of Pictures (Group of Pictures, GOP) value. The GOP value refers to the length of the GOP, that is, the number of continuous frames from one I frame to the next I frame (including the first I frame). Among them, GOP refers to a picture group composed of several consecutive pictures, whic...
