• Local file creation of ffmpeg hls http stream

  10 juillet 2018, par Emilian

  After researching all the options for ffmpeg hls streaming and setting it up for uploading to a http server i encountered a problem, ffmpeg also creates local files for the segment/playlist in the current working directory.

  What im trying to achieve is upload to a server and serve the segments and playlist from memory and not from disk. Tried setting a http url for segments like this :

  ffmpeg -re -i filter_test.ts -f hls -hls_segment_filename http://localhost:3000/segment/playlist_%03d.ts -method PUT http://localhost:3000/segment/playlist.m3u8

  but that also didnt work.

  Is there any way to stop ffmpeg from creating local files for the hls stream and only upload them to the server ?

  In the logs it says

  [hls @ 00000274041104e0] Opening 'http://localhost:3000/segment/playlist_000.ts' for writing
  
  [http @ 00000274046a2fa0] request: POST /segment/playlist_000.ts HTTP/1.1

  but nothing about writing it to a file.

• Run ffmpeg as window service

  7 juin 2018, par Brad Reiter

  My setup is like this :

  It contains components :

  • Web Cam : which send out the RTP packets when i get a stream request
  • Agent server : Which receives the stream from the Webcam and forwards
    the same to ffmpeg server.
  • ffmpeg server : this where i need to run the ffmpeg as window service,
    receives the rtp stream sent by agent server and create a ts file.

  What have i done is :

  I have setup the ffmpeg in one of my dev environment using this link :

  https://video.stackexchange.com/questions/20495/how-do-i-set-up-and-use-ffmpeg-in-windows

  My problems :

  • How to make ffmpeg run as daemon.?
  • How can i make ffmpeg aware that new stream is coming from agent
    server and start creating a ts file.?
  • Is there a way in ffmpeg that i reserve ports for ffmpeg and make it
    listen to all the ports for eg : reserve 2000 - 3000 ports and listen
    to them as soon as rtp stream arrives, convert to ts stream.

  I need to use ffmpeg in a Node.js application that runs in a docker container (created using docker-compose). I'm very new to Docker, and would like to know how to command Docker to install ffmpeg when creating the image.

  



  DockerFile

  



  FROM node:carbon
WORKDIR /usr/src/app

# where available (npm@5+)
COPY package*.json ./
RUN npm install -g nodemon
RUN npm install --only=production
COPY . .

EXPOSE 3000
CMD [ "npm", "start" ]
