• View the incoming live mpeg stream from python socket

  19 janvier 2017, par ITried

  So I have an Intel Edison microcontroller running Linux that has a usb cam attached to it. It has a python script that uses ffmpeg to send the mpeg stream to a specific ip:port. I have another ’server’ script on my computer that opens a basic socket and binds on that port. The stream is clearly transferring because when I receive on the server, I print to terminal and all this gibberish and outputs. My question is how can I use ffmpeg or OpenCV (or anything else really) to receive from this port and view it real time ?
  On the Intel Edison, this command transmits data :

  os.system("/home/root/bin/ffmpeg/ffmpeg -s 640x480 -f video4linux2 -i /dev/video0 -f mpeg1video -b 800k -r 30 http://myip:8082")

  On the ’server’ side this the basic socket for binding and receiving.

  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  
  s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
  
  s.bind(('',8082))
  
  s.listen(1)
  
  conn, addr = s.accept()
  
  print "Connected to:", addr
  
  while True:
  
      data = conn.recv(1024)
  
      if data:
  
          print data

  I want to be able to view the incoming stream live, capture images, or save to video file. I tried looking online, but have not found any for live stream capture through python socket.

  thanks in advance !

• Gphoto2 live view with nikon dslr5100 pipes to ffplay for 3 seconds then dies

  30 avril 2020, par Will Simpson

  I am trying to use my DSLR camera with OBS.
I have installed Gphoto2 on mac and have managed to get a connection to the camera.
Now I am trying to get some kind of live view window that I can then capture in OBS.

  



  The problem is when I use the following command, the camera makes like it is about to go into movie mode, the window opens and then the image begins streaming for usually about 4 seconds before it freezes.

  



  gphoto2 --port usb:250,006 --capture-movie --stdout | ffplay -i pipe:0 -vcodec mjpeg


  



  I specify the port because I also have my iphone camera in another window in OBS

  



  Does anyone have any suggestions ?
