• where to save mpd file in raspberry pi so dash.js can access it remotely ?

  11 mai 2016, par Djm

  This is very high level question. I want to stream a live video from raspberry pi. I want to be able to watch live video in the browser remotely being streamed by the Raspberry pi.I want to use DASH stream protocol, and Dash.js as client to HTML5. I have looked through different tutorials but i am still puzzled about how this works.I understand that (assuming you have already prepared your videos with FFMPEG tool) from the client Dash.js
  you have to make a call/request and pass a url to your mpd file. My question is where would you save the file in raspberry pi especially if the Dash client is in a different web app(i want to make the call remotely) ?

• Android - Adding Effects to Videos like Instagram

  10 mai 2016, par San

  I am in need of a idea to apply filters to video like Instagram, video trimming and fetching images from the video. I have researched a lot and all I can come up with is the following ways to achieve what I want :

  1. FFMPEG
  2. Open CV
  3. Camera2 API

  FFMPEG :

  As far as FFMPEG is considered, majority of the average level droid devs feel that its a pain cause it involves NDK and compiling the FFMPEG commands.The above mentioned link is self-explanatory and it saves me the pain of setting up the NDK but the biggest drawback in this is that its not stable and its REALLY slow.
  My query on this topic is that how do I compile FFMPEG into my project. I have gone through several links to integrate FFMPEG as follows :

  One

  Two

  Three

  The third link seemed to make sense but ultimately I couldn’t understand completely and go where,do what after following those steps.

  Question 1 :

  Is there is a solid Android - FFMPEG Integration Document that can help a beginner like me ?

  Open CV

  Question 2 :

  I haven’t tried Open CV yet but will it be worth it ?

  Camera2 API

  Question 3 :

  As far as I researched, I can see that the Camera2 API can help us shoot videos and images with effects added to it but will it be useful for me to process the already existing videos and images ? I don’t have the requirement to add effects to the camera while its captured, its aftermath is where I want to add my effects.

  If someone is kind enough to accept my stupidity and help me out, I am thankful to them.

  Will going ahead with FFMPEG be good or OpenCV or Camera2 API will be better ?

• Live TV Stream to Android

  8 mai 2016, par Hd Dream

  I am new user on stackoverflow.
  I wrote you today to get answer and solution to my problem.
  I have input stream come from vlc. I need that all android connected to my network can watch stream in live in the same time like an online channel tv.
  I saw for this channel

  Code : Select all
  www.canal2international.net/live.php

  there is a same ts file is generated for each 45 second.

  I need to do the same but with a mp4 file that I insered on html5 video tag.
  for that I tried to convert my input stream with this cmd on ffmpeg

  Code : Select all
  ffmpeg -i 192.168.1.10:8620 -c:v libx264 -profile:v baseline -c:a aac -ar 44100 -ac 2 -b:a 128k -f segment -segment_time 45 -segment_format_options movflags=+faststart -segment_list D :\live\play.m3u8 -segment_list_size 2 D :\live\watch%03d.mp4

  I’m not satisfied. I can’t insert m3u8 file in html5 video tag because android don’t read it and his content.

  I tried another code that I can say little similar that the result of this page

  Code : Select all
  www.canal2international.net/live.php

  Code : Select all
  ffmpeg -i 192.168.1.10:8620 -hls_flags single_file D :\live\play.m3u8

  It generated two files, a ts and a m3u8.
  I know that html5 video tag can read ts file. Maybe there is a solution somewhere.

  The second way I don’t like in this code is ts file don’t read in real time. When I read file it begin from the first encoding.

  All android connected to my network must watch in real time !

  I don’t know how to solve my problem that’s why I write in thie forum.

  Thank you in advance for all your help !
