• ffmpeg image and flask app in two different containers in Docker compose. How do I use ffmpeg in flask app ?

  14 novembre 2017, par Conor Quinn

  Here is my docker compose yml file :

  ffmpeg:
  
      image: jrottenberg/ffmpeg:ubuntu
  
      tty: true
  
  flask_app:
  
    build: ./flask_app
  
    #image: conorquinn01/composeapp
  
    command: python ./flask_app/app.py
  
    ports:
  
     - "5000:5000"
  
    volumes:
  
     - .:/muse_compose2
  
    links:
  
      ['ffmpeg']

  Not sure how to do this. Thanks.

• Dump WebRTC stream to a file

  20 novembre 2014, par Mondain

  I’d like to capture the audio and video from a WebRTC stream to a file or pair of files, if audio and video require their own individual files. The audio and video are not muxed together and are known to be available on a set of server udp ports :

  Port   Encoding
  5000 - VP8 video
  5001 - RTCP (for video)
  5002 - Opus audio @48kHz 2 channels
  5003 - RTCP (for audio)
  

  The SDP file / data is not available and DTLS may be used.

  I would prefer to use avconv or ffmpeg to capture the stream, unless a better tool is suggested.

  Edit : I’ve found that this as inquired will most likely not work. Until I hear otherwise, none of these tools support the initial DTLS handshake followed by the data transmission via SRTP.

• ffmpeg video stream to app c# [on hold]

  3 septembre 2014, par Alexey Medvedev

  I am trying to make a video mixer for online broadcasts. To do this, I use ffmpeg and C #. I had a problem with the transfer of the video stream from ffmpeg to my program. I would like to receive a stream of ffmpeg using network protocols (e.g. TCP, UDP or others) or capturing if from ffplay window, but I don`t how I can do it. Can you give me some ideas ?

  For example, I have command for ffmpeg : "ffmpeg -i video1.mp4 -f mpegts udp:127.0.0.1:5000" or same command with other output formats or network protocols. How i can read video stream from the port and convert it to Bitmap ?
  I need to send video stream from my program from computer A to my program to computer B. I write program on C#. I dont know how I can compress video which I must send between my computers and I decided to use Ffmpeg. Now, I can streaming video from my program in computer A to ffmpeg and compress it with parameters which I need.
  On second computer I can read this steam using ffmpeg or ffplay, but I don`t know how I can get this stream into my program.
  1) How can I get this stream in my program ? Which libraries can you recommend me ?
  2) Do you know any libraries which can compress video, instead of using ffmpeg ?
