To reduce delays in FFmpeg, you can try the following methods:<\/p>\n

    \n
  1. Just Down\u539f\u3002<\/li>\n<\/ol>\n
    ffmpeg -re -i input.mp4 output.mp4\r\n<\/code><\/pre>\n
      \n
    1. Adjust the bitrate and frame rate of the output file to match those of the input file. For example, if the input file has a frame rate of 30fps, you can use the following command to set the frame rate of the output file to 30fps:<\/li>\n<\/ol>\n
      ffmpeg -i input.mp4 -r 30 output.mp4\r\n<\/code><\/pre>\n
      One option could be:
      \nYou can set the video bitrate of the output file using the -b:v parameter, for example:<\/p>\n
      ffmpeg -i input.mp4 -b:v 2M output.mp4\r\n<\/code><\/pre>\n
        \n
      1. synchronization of vertical refresh\u7387<\/li>\n
      2. zero, one, two<\/li>\n<\/ol>\n
        ffmpeg -i input.mp4 -vsync 0 output.mp4\r\n<\/code><\/pre>\n
          \n
        1. -size of the buffer<\/li>\n<\/ol>\n
          ffmpeg -i input.mp4 -bufsize 10M output.mp4\r\n<\/code><\/pre>\n
          These methods may need to be adjusted and tried according to specific situations in order to find the best setting that suits your needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
