• ffmpeg tcp error -138 and HTTP error 503 while downloading from https source

  15 juin 2022, par PeterM

  i'm trying to download media (video) files from sharepoint (i have view access), but during the process i get several "Connection to tcp ://xxx.xxxxx.ms:443 failed : Error number -138 occurred" or "HTTP error 503 Service Unavailable" errors

  


  tcp error

  


  HTTP error 503

  


  i get more errors with the following parameters :

  


  ffmpeg -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


  


  less errors with :

  


  ffmpeg -re -vsync 1 -i "https://theURLtoTheManifestYouCopiedHere" -codec copy downloadedVideo.mp4


  


  the options suggested in this article didn't help : https://medium.com/intrasonics/robust-continuous-audio-recording-c1948895bb49

  


  the output video is ok, but sound seems to be missing occasionally (a few seconds worth)

  


  ffmpeg version 2022-06-12-git-4d45f5acbd-essentials_build-www.gyan.dev

  


  any advice ?

  


• FFMPEG HTTP Stream error, failed : Connection refused

  17 juillet 2022, par Halo Gass

  I tried to stream a video frame from opencv to network using MPEG-Dash, HLS, or RTSP via FFMPEG, but everytime I tried everything, it always throw "Connection Error, Connection Refused" even streaming to 127.0.0.1.

  


  Here the code for testing :

  


  import subprocess
import cv2
rtmp_url = "rtmp://127.0.0.1:1935/stream/pupils_trace"

# webcamera is 0, also you can set a video file name instead, for example "/home/user/demo.mp4"
path = 0
cap = cv2.VideoCapture(path)

# 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),
           '-r', str(fps),
           '-i', '-',
           '-c:v', 'libx264',
           '-pix_fmt', 'yuv420p',
           '-preset', 'ultrafast',
           '-f', 'flv',
           rtmp_url]

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


while cap.isOpened():
    ret, frame = cap.read()
    if not ret:
        print("frame read failed")
        break

    # YOUR CODE FOR PROCESSING FRAME HERE

    # write to pipe
    p.stdin.write(frame.tobytes())


  


  and below is the log :

  Here what I tried (All of it always "Connection Refused")

  


  

  1. Running the code directly

  


  2. Running the code using sudo

  


  3. Run with 'sudo su'

  


  4. Allow the port used in ufw

  


  5. Disable ufw

  


  6. I tried executing command directly in terminal, also throws "connection refused"

  


  7. using 127.0.0.1 or "localhost" or 0.0.0.0 or my local IP, everything throws connection error

  


  8. Tried UDP and TCP

  


  


  Anyone can help me ?
Thanks

  


• avutil/error : Add HTTP 429 Too Many Requests AVERROR code

  22 avril 2024, par Derek Buitenhuis

  avutil/error : Add HTTP 429 Too Many Requests AVERROR code
  This is a common error code from e.g. CDNs or cloud storage, and
  
  it is useful to be able to handle it differently to a generic
  
  4XX code.
  Its source is RFC6585.
