Implementation Of Dynamic Scheduling Technology Of Video Transcoding Resources Based On Nginx

Nowadays,with the rapid development of mobile Internet,mobile video services take a large proportion of the services,and have become a popular way to share information.But the development of communication technology and the diversity of access devices,greatly increased the complexity and heterogeneity of mobile streaming video applications,such as screen size,the lower rate,frame rate adjustment,etc.limited conditions will lead to changes in the compressed stream.In order to provide a consistent user interface to access streaming media,video transcoding technology is introduced.The transcoder can convert the input compressed video stream from one format to another format.With the increasing demand for video transcoding,need multiple transcoders to meet the massive user concurrent video transcoding requests.As a transcoder cluster system,load balancing is used to solve the servers problem of a rational allocation of a large number of concurrent requests.But with the increase of the users of video requests,single transcoder can not meet the demand,to the deployment of tasks on multiple transcoder,we use nginx load balancing to the pool of transcoding,study of the dynamic scheduling algorithm,improve the quality of streaming media service.First of all,the test environment is set up to verify the function of each module in the dynamic scheduling scheme.At the same time,through the load test on single transcoder,transcoder clusters in different situations,analysis of the test results prove the nginx transcoding resources dynamic scheduling scheme than the static round robin load balancing can deal with back-end transcoder node load dynamic change based on,can better play the transcoder node performance.
