Abstract

The application discloses a code stream adjustment method, device and computer storage medium. The code stream adjustment method includes: determining whether the sum of the decoding capabilities required by the opened channels is greater than the maximum decoding capability provided by the decoding device; if it is greater than the maximum decoding capability, sorting the channels according to the evaluation indicators of each channel ; Perform downsampling operations on the sorted channels in turn. Through the above method, the present application can solve the problem of black screen display caused by the decoding requirement for opening the channel exceeds the decoding capability of the device, thereby improving the user's preview experience.

Description

technical field [0001] The present application relates to the field of video monitoring, in particular to a code stream adjustment method, device and computer storage medium. Background technique [0002] After being encoded by the front end, the video data monitored by the network camera is transmitted to the monitoring display terminal for preview through the network bandwidth. The encoded video data is decoded by the network hard disk video recorder, and the monitored video can be previewed. The traditional solution is to apply for a decoder after the channel preview is enabled. After the preview is enabled, the decoding capability will be occupied. However, each DVR has a corresponding decoding capability and supports a certain number of decoding channels. One decoding channel corresponds to a video display window. When the number of decoding channels increases, the occupied decoding capacity also increases, which may cause the last opened channel to fail to decode and p...
