• DIY video file streaming from linux/osx to iOS devices

  27 septembre 2016, par sfactor

  This is for a hobby project. I want to learn about video streaming and also create something that’s useful for me as well.

  The project should be able to run a server on my macbook and a client on my iPad that will allow me to watch the videos I’ve got stored on my laptop without having to copy them in my iPad over my wifi.

  I know there are solutions like Plex, Air Video etc. that allow me to do it. But since my goal is to practice writing some client/server code, I want to create something myself with the basic functionality of these apps.

  I figured I’d probably need something like ffmpeg and Apple’s HTTP Live Streaming (HLS), but I don’t have a Apple developer account to be able to use it. I do have Xcode in my mac. So, some free 3rd party library for HLS or something equivalent. I also fond this tool called https://www.bento4.com.

  How would I go about getting started with such an application and what are the libraries I could use to accomplish this ?

• Stream MP4 using FFMPEG on remote VLC

  8 novembre 2016, par Satish

  I’m trying to stream a MP4 file from my Embedded device and play it in the VLC in my laptop. My H/W setup look like below

  --------------                ------------------      
  
  |  Board     |     Ethernet   | Window Laptop  |
  
  | (Android N)|----------------|     VLC        | 
  
  | 192.168.1.5|                |  192.168.1.2   |  
  
  |   ffmpeg   |                |----------------|
  
  |------------|  

  I’m trying to issue ffmpeg command from board side and it look like below

  Embedded board ---
  ./ffmpeg -re -i vid.mp4 -vcodec copy -an -f rtp rtp ://192.168.1.2:1234 -vn -acodec copy -f rtp rtp ://192.168.1.2:1234

  On Laptop VLC side my sdp file look like below

  v=0
  
  o=- 453271780569021 453271780586833 IN IP4 /192.168.1.5
  
  s=Unnamed
  
  i=N/A
  
  c=IN IP4 /192.168.1.2
  
  t=0 0
  
  a=recvonly
  
  m=video 1234 RTP/AVP 96
  
  a=rtpmap:96 H264/90000

  I don’t see any stream on VLC side. I believe there is something wrong command which I couldn’t figured yet. Please let me know if anyone knows how I can achieve this. By the way the video file is not limited to MP4 format , i’m open for any file format.

  Thanks, Satish

• ffmpeg and ffserver live stream to HTML5

  19 novembre 2016, par andrixnet

  What would be the setup for a reasonably supported live stream with ffmpeg and ffserver ?

  I mean I know ffmpeg can’t live stream MP4.
  It can live stream flv, but that requires flash plugin.
  I’ve read about HLS which is specific for Apple target devices.

  My target is mostly windows PC/laptop (Firefox, Chrome, Opera, optionally MSIE 10+) and Android smartphones (android 4+).
  Mac OSX and iOS devices are of little interest, if it works, ok, but not a requirement.

  On the playback side the target is pure HTML5 with <video></video> tag. No Flash.
  On the server side : ffserver.
  On broadcast side : ffmpeg with capture device as video and audio source.

  Can anyone suggest a configuration for ffmpeg+ffserver ?
