• 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

  


• Why does ffmpeg keep using more and more RAM and crash ?

  29 décembre 2022, par József Márton Kakas

  I am using the following command with ffmpeg to encode a video file using the libsvtav1 codec : ffmpeg -i hevc.mkv -map 0:v:0 -c:v:0 libsvtav1 -preset 8 -crf 22 -format matroska av1.mkv.

  


  However, ffmpeg is using up all of my available RAM and crashing. I have also tried using the libx264 codec, but the same issue occurs, although it happens more slowly. I have already allocated 12 GB of RAM to ffmpeg, but it still seems to be insufficient. How can I prevent ffmpeg from using all of my available RAM and crashing when using either the libsvtav1 or libx264 codecs ?

  


  I have tried it on another VM, but the same issue occurs. Here is the full output of the program.

• ffmpeg on RTSP stream works on local but fail on Heroku

  13 avril 2022, par mkto

  I have a piece of Node.js script that :

  


  

  1. Extract one image frame from an mp4 file using ffmpeg

  


  2. Extract one image frame from an RTSP stream using ffmpeg.

  


  


  They works on local. However when uploaded on Heroku using a ffmpeg Heroku buildpack :
https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest/issues?q=rtsp, extract RTSP fail silently without any error output.

  


  This is the comparison of the ffmpeg versions :
