• YouTube isn't recieving any data from my FFmpeg stream to the RTMP server

  9 novembre 2020, par Eniola Oyewole

  So I have a python programming running on my computer that is sending the same image to an RTMP server every second. The python program is reading the image and then sending the data, from the console everything seems ok but youtube says that its not receiving any data. My code :

  


  import subprocess
import cv2
rtmp_url = "rtmp://b.rtmp.youtube.com/live2/"

fps = 1.5

width = 600
height = 600

# 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',
           '-f', 'flv',
           rtmp_url]

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

while True:
  f = cv2.imread('assets/temporary.png')

  p.stdin.write(f.tobytes())


  


  My console :

• Why does the ffmpeg process hang ?

  15 janvier 2021, par lavAzza

  I try to make video from 2 jpeg (6912x3456 px, files is large it is 360 panoramas) with ffmpeg by

  


  ffmpeg -r 1/4 -pattern_type glob -i "my_dir/*.jpg" -c:v libx264 -profile:v high -crf 18 -vf "fps=30,format=yuv420p" -movflags +faststart output.mp4


  


  And ffmpeg process hang. I get

  And only Ctrl+C helps.
But when there is one jpg file in the folder, ffmpeg is work fine.
My ffmpeg command works fine on another PC with WSL Debian on Win10. What is problem ?
