• Compile FFMPEG Using Eclipse Android

  3 septembre 2013, par Ivelius

  NDK experts , I need your help...

  My goal is to easily compile ffmpeg library using android NDK and eclipse.

  What I usally do when I want to develop using NDK , is right click on android project in eclipse ->Android Tools -> Add Native support. And Everything works and compiles.
  Every time I want to build my project , I just hit "Build" button (with a hammer icon on it).

  Now I just need to add all ffmpeg libraries and run a simple program like this.
  I downloaded latest ffmpeg libraries from official website.I've extracted downloaded content into JNI library . And when I try to build , I get countless errors. Something like
  "fatal error : libavutil/avconfig.h : No such file or directory" ...

  My Android.mk file looks like this :

  LOCAL_PATH := $(call my-dir)
  
  
  
  include $(CLEAR_VARS)
  
  include $(call all-subdir-makefiles)
  
  
  
  LOCAL_MODULE    := HELLONDK
  
  LOCAL_SRC_FILES := hello-ndk.cpp
  
  
  
  include $(BUILD_SHARED_LIBRARY)

  EDIT :
  I've been looking for a solution for a few days before posting this question.

• Run 3 Docker images together as a single service

  20 juin 2018, par kitce

  I want to run 3 Docker images as a single service. They are the official nginx, jrottenberg/ffmpeg and a custom image.

  The custom image will return video files for HTTP requests on port 80, e.g. http:////video.mp4.

  I want to make the video files available for HLS in M3U8 playlist (or other better formats ?).

  The main idea is as follows :

  • Encode video.mp4, output video.m3u8 and segment files with ffmpeg
  • Serve the video.m3u8 and segment files with Nginx
  • The final and the only available web service of the container is http:///.m3u8.
  • Encode only when someone is requesting it (i.e. trigger the encoding when the first request comes, stop encoding and delete segment files when nobody requests it)

  I tested the HLS part with ffmpeg and it works. I am just not sure about how to put Nginx and ffmpeg to work together.
