Network video is very popular, users often upload video, Video site allows specific coded video to maintain the original specification at a certain peak rate, and then to add lower-level specifications to the code. At present, many analysis tools can only get the maximum rate of the whole video, and cannot get the rate map, nor support the new video format. This design proposes using the Swift language to display the video bitrate analysis data in different forms, FFmpeg/ffprobe applications is called to analyze video stream. The experimental results show that the design can get the information of all frames of the video to depict the column chart, and can display the corresponding time point of the frame, so that users can modify the area exceeding the rate limit, so as to achieve the goal of no forced transcoding. In addition, this design supports HEVC format video.
