YouTube isn't recieving any data from my FFmpeg stream to the RTMP server
9 novembre 2020, par Eniola OyewoleSo 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 :

And htop shows



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 ?
