Abstract
This application provides a video transmission method and apparatus, and pertains to the field of network technologies. In this application, after procedures such as obtaining positions of I-frames of videos, arranging the positions of the I-frames, and indicating a video capturing device management platform to adjust a position of an I-frame of a video are performed, the I-frames of the videos are staggered at a radio air interface, helping resolve a problem that I-frames of videos collide, and reduce demands for wireless network bandwidths from the plurality of videos. The problem that I-frames of videos collide is resolved on a per-cell basis, with I-frames arranged for each cell.
Claims20
A video transmission method implemented by computer device, comprising:
- obtaining first positions of I-frames of a plurality of videos in a first cell;
- performing arrangement based on the first positions of the I-frames of the plurality of videos, to obtain second positions of the I-frames of the plurality of videos, wherein a distance between second positions of I-frames of adjacent videos of the plurality of videos meets a condition;
- and
- sending indication information to a video capturing device management platform, wherein the indication information indicates to adjust a position of an I-frame of a first video of the plurality of videos from a first position of the I-frame of the first video to a second position of the I-frame of the first video, and the first position of the I-frame of the first video is different from the second position of the I-frame of the first video.
A video transmission method implemented by a coding device for a video capturing device management platform, comprising:
- receiving indication information, wherein the indication information indicates to adjust a position of an I-frame of a first video of a plurality of videos from a first position of the I-frame of the first video to a second position of the I-frame of the first video, and the first position of the I-frame of the first video is different from the second position of the I-frame of the first video;
- obtaining, based on the indication information, an amount of adjustment that is for the position of the I-frame of the first video;
- and
- sending an adjustment command to a video capturing device, wherein the video capturing device is a data source of the first video, and the adjustment command instructs to adjust the position of the I-frame of the first video by the amount of adjustment.
A computer device, comprising:
- a memory storing computer programming instructions;
- and
- one or more processors coupled to the memory and configured to execute the computer programming instructions to cause the computer device to perform steps of:
- obtaining first positions of I-frames of a plurality of videos in a first cell;
- performing arrangement based on the first positions of the I-frames of the plurality of videos, to obtain second positions of the I-frames of the plurality of videos, wherein a distance between second positions of I-frames of adjacent videos of the plurality of videos meets a condition;
- and
- sending indication information to a video capturing device management platform, wherein the indication information indicates to adjust a position of an I-frame of a first video of the plurality of videos from a first position of the I-frame of the first video to a second position of the I-frame of the first video, and the first position of the I-frame of the first video is different from the second position of the I-frame of the first video.
