• How to slow down the ouput speed of ffmpeg while streaming to a RTMP server ?

  25 avril 2023, par Loc Bui Nhien

  I'm currently trying to process multipul short videos (each is about 0.5s long) to be stream on a RTMP server. However, the output/fps/speed when sending is too high (results printed here), making the server crashed very often.

  


  Here is the the code and settings that I'm using :

  


  import cv2
import ffmpeg
import av
import numpy as np
import os
import subprocess

url = "rtmp://..."
key = "..."
rtmp_url = url + "/" + key

cap = cv2.VideoCapture('traffic.mp4')

# gather video info to ffmpeg
fps = int(cap.get(cv2.CAP_PROP_FPS))
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH))
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))

# command and params for ffmpeg
command = ['ffmpeg',
           '-y',
           '-f', 'rawvideo',
           '-vcodec', 'rawvideo',
           '-pix_fmt', 'bgr24',
           '-s', "{}x{}".format(width, height),
           '-i', '-',
           '-r', '20',
           '-c:v', 'libx264',
           '-pix_fmt', 'yuv420p',
           '-preset', 'slow',
           '-f', 'flv',
           rtmp_url]

# using subprocess and pipe to fetch frame data
p = subprocess.Popen(command, stdin=subprocess.PIPE, shell=True)

received_video_path = 'ReceivedRecording'
while True:
    video_files = [filenames for filenames in sorted(os.listdir(received_video_path), reverse=True)]
    # Loop through the videos and concatenate them
    for filename in video_files[:len(video_files)-3]:
        video = cv2.VideoCapture(os.path.join(received_video_path,filename))

        # Loop through the frames of each video
        while True:
            ret, frame = video.read()
            if not ret:
                # End of video, move to next video
                video.release()
                break
            
            p.stdin.write(frame.tobytes())

        os.remove(os.path.join(received_video_path, filename))


  


  The same settings work fine with the webcam, but I can not control the speed and fps of it sending to the server. The stream on the server seems to work fine with a steady 20fps as intended.

  


• why node-media-server not creating sub folders in server while implementing Live video with RTMP ?

  10 mars 2020, par Kadam Saikumar

  I tried this configuration in local it got works and it creates **./media/live/STREAM KEY** folder and storing video data (MP4 file).
  
      If i push the same code in server it doesnot create sub folders **live/STREAMKEY** and i am using node version 8 and linux server and ffmpeg 4.
  
  
  
  
  
  const nodeMediaServerConfig = {
  
        // logType: 3,
  
        rtmp: {
  
          port: 1935,
  
          chunk_size: 60000,
  
          gop_cache: true,
  
          ping: 60,
  
          ping_timeout: 30
  
        },
  
        http: {
  
          port: 8000,
  
          mediaroot: './media',
  
          allow_origin: '*'
  
        },
  
        trans: {
  
          ffmpeg: '/usr/bin/ffmpeg',
  
          tasks: [
  
            {
  
              app: 'live',
  
              ac: 'aac',
  
              mp4: true,
  
              mp4Flags: '[movflags=faststart]'
  
            }
  
          ]
  
        }
  
      };
  
  
  
      var nms = new NodeMediaServer(nodeMediaServerConfig);
  
      nms.run();

  If i create manually folders will it be useful in server ?
