  • How to receive byte-stream by using gstreamer with python subprocess module or gst-launch-1.0 command ?

    21 avril 2022, par yuniversi

    I want to receive byte-stream by using gstreamer with python subprocess module.
Now I can successfully use ffmpeg to pull the byte-stream. As shown below.

    


    import cv2
import subprocess as sp


height = 714
width = 420
rtsp_url = 'rtsp://127.0.0.1:8554/video'

# command
command = ['ffmpeg',
            '-i', rtsp_url,
            '-f', 'rawvideo',
            '-s',str(width)+'*'+str(height),
            '-pix_fmt', 'bgr24',
            '-fflags', 'nobuffer',
            '-']

p = sp.Popen(command, stdout=sp.PIPE, bufsize=10**8)

while True:
    raw_image = p.stdout.read(width*height*3)
    image =  np.fromstring(raw_image, dtype='uint8')
    image = image.reshape((height,width,3)).copy()
    cv2.imshow('image', image)
    key = cv2.waitKey(20)


    


    I want to use gstreamer command instead of ffmpeg. So far, I have realized writing byte-stream to a file by using gstreamer command line.

    


    gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/video latency=0 drop-on-latency=true ! rtph264depay ! video/x-h264, stream-format='byte-stream' ! filesink location=/home/name/stdout


    


    But it can't output byte-stream to pipe, so the terminal dosen't display byte-stream, not like ffmpeg command. How to change this command to output byte-stream through pipe so I can read from pipe.
Thank you for taking the time to answer for me !

    


    This is RTSP streaming code.

    


    import cv2
import time
import subprocess as sp
import numpy as np


rtsp_url = 'rtsp://127.0.0.1:8554/video'
video_path = r'test.mp4'
cap = cv2.VideoCapture(video_path)

# Get video information
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))
print('fps={}'.format(fps))

# command
command = ['ffmpeg',
            '-re',
            '-y',
            '-stream_loop', '-1',
            '-f', 'rawvideo',
            '-vcodec', 'rawvideo',
            '-pix_fmt', 'bgr24',
            '-s', "{}x{}".format(width, height),
            '-r', str(fps),
            '-i', '-',
            '-c:v', 'libx264',
            '-pix_fmt', 'yuv420p',
            '-preset', 'ultrafast',
            # '-flags2', 'local_header',
            '-bsf:v', "'dump_extra=freq=k'", 
            '-keyint_min', '60',
            '-g', '60',
            '-sc_threshold', '0', 
            '-f', 'rtsp',
            '-rtsp_transport', 'tcp',
            '-muxdelay', '0.1', 
            rtsp_url]

p = sp.Popen(command, stdin=sp.PIPE)

cnt = 0
t_start = time.time()
while (cap.isOpened()):
    t_cur = time.time()-t_start

    ret, frame = cap.read()
    if not ret:
        cnt += 1
        print("count: {}".format(cnt))
        cap = cv2.VideoCapture(video_path)
        continue

    p.stdin.write(frame.tobytes())

    cv2.imshow('real_time', frame)

    key = cv2.waitKey(20)
    if key == 27:
        p.terminate()

  • nginx rtmp module fails to stream MP4 format

    23 avril 2019, par Keivan

    I have media server running on Nginx rtmp module + ffmpeg
    It is working 100% fine with FLV format but with MP4 it does not create .m3u8 file and stream chunks.
    here is nginx.conf file :

    worker_processes  auto;
    

    
events {
    
    worker_connections  1024;
    
    multi_accept on;
    
}
    

    
rtmp {
    
  server {
    
    listen 1935;
    
    chunk_size 4000;
    

    
    application live {
    
        live on;
    
        record off;
    

    
        hls on;
    
    hls_path        /HLS/live;
    

    
        hls_keys on;
    
        hls_key_path       /HLS/keys;
    
        hls_key_url        https://fakeurl:8441/keys/;
    
    hls_fragments_per_key   10;
    

    
        hls_fragment 3s;
    
        hls_playlist_length 10s;
    
        deny play all;
    
    }
    
  }
    
}
    

    
http {
    
    include       mime.types;
    
    tcp_nopush on;
    
    directio 512;
    
    default_type  application/octet-stream;
    
    sendfile      off;
    

    
    server {
    
        listen       8441 ssl;
    
    server_name  fakeurl;
    

    
        ssl_certificate /home/ubuntu/Keys/server.crt;
    
        ssl_certificate_key /home/ubuntu/Keys/server.key;
    

    
        location /keys {
    
            root /HLS/;
    
        }
    

    
        location / {
    
            root   html;
    
            index  index.html index.htm;
    
        }
    

    
        location /live {
    

    
            # Disable cache
    
            add_header 'Cache-Control' 'no-cache';
    

    
            # CORS setup
    
            add_header 'Access-Control-Allow-Origin' '*' always;
    
            add_header 'Access-Control-Expose-Headers' 'Content-Length';
    

    
            # allow CORS preflight requests
    
            if ($request_method = 'OPTIONS') {
    
                add_header 'Access-Control-Allow-Origin' '*';
    
                add_header 'Access-Control-Max-Age' 1728000;
    
                add_header 'Content-Type' 'text/plain charset=UTF-8';
    
                add_header 'Content-Length' 0;
    
                return 204;
    
            }
    

    
            types {
    
                application/vnd.apple.mpegurl m3u8;
    
            }
    

    
            root /HLS/;
    
        }
    

    

    
        #error_page  404              /404.html;
    

    
        # redirect server error pages to the static page /50x.html
    
        #
    
        error_page   500 502 503 504  /50x.html;
    
        location = /50x.html {
    
            root   html;
    
        }
    
    }
    
}

    and this is FFmpeg command for creating converting my RTP stream to MP4 and stream it to RTMP server :

    ffmpeg -protocol_whitelist 'file,udp,rtp' -i input.sdp -c:v libx264 -pix_fmt yuv420p -profile:v baseline -level 3.0 -g 30 -r 30 -c:a aac -b:v 400k -preset ultrafast -tune zerolatency -movflags frag_keyframe -f mp4 rtmp://0.0.0.0:1935/live/stream1

    I can confirm ffmpeg works fine and it is stable with the input stream, if I change output format to flv, rtmp server creates stream1.m3u8 file and everything is fine. But with mp4, mov or m4v formats nginx does not create anything.
