simple-live-audio-streamer

A low volume, live streaming audio app over socks5 proxy.

Build Dependencies

We have the following build dependencies

XCode Most is written in c++ and hence must be compiled using XCode. 2. cmake etc. to compile ffmpeg and lighttpd
Nodejs For bundling and minifying html files we need the following modules.
1. npm install uglify-js -g
2. npm install html-minifier -g
3. npm install clean-css-cli -g

Prebuild binaries

This program needs a prebuild copy of ffmpeg and lighttpd Please compile these binaries statically and place them inside components/binaries/

FFmpeg

To compile FFmpeg use the following commands

git clone --depth 1 https://github.com/FFmpeg/FFmpeg
./configure \
    --enable-static \
    --disable-autodetect \
    --disable-programs \
    --disable-runtime-cpudetect \
    --disable-doc \
    --disable-everything \
    --enable-decoder="aac,pcm*" \
    --enable-encoder=aac \
    --enable-parser=aac \
    --enable-demuxer=mpegts,aac \
    --enable-protocol=file,pipe,hls \
    --enable-bsf=aac_adtstoasc,h264_mp4toannexb,hevc_mp4toannexb \
    --enable-muxer=adts,latm,mpegts,segment,hls \
    --enable-filter=pan,volume,aresample \
    --enable-indev=avfoundation \
    --disable-runtime-cpudetect \
    --enable-pthreads \
    --enable-ffmpeg \
    --enable-small \
    --enable-avfoundation
make -j4

Lighttpd

To compile lighthttpd use

ccmake -Wno-dev -DBUILD_STATIC=ON -DWITH_OPENSSL=0 -DWITH_LUA=0 -DWITH_ZLIB=0 -DWITH_PCRE=0 -DWITH_BZIP2=0 -DWITH_WEBDAV_PROPS=0 ..

When you get the error plugin-static.h not found see https://redmine.lighttpd.net/boards/3/topics/5912. Namely in the src directory of lighttpd we created a file plugin-static.h with the following contents

PLUGIN_INIT(mod_auth)
PLUGIN_INIT(mod_redirect)
PLUGIN_INIT(mod_rewrite)
PLUGIN_INIT(mod_cgi)
PLUGIN_INIT(mod_fastcgi)
PLUGIN_INIT(mod_scgi)
PLUGIN_INIT(mod_ssi)
PLUGIN_INIT(mod_proxy)
PLUGIN_INIT(mod_indexfile)
PLUGIN_INIT(mod_dirlisting)
PLUGIN_INIT(mod_staticfile)
PLUGIN_INIT(mod_setenv)

Mac App bundle

For MacOS an application is a folder containing all the resources the app needs. To create an application one needs to compile the Objective-C app in components/bundle/src/Grace Livestream.xcodeproj and export it to components/bundle/dist/bundle.app

Later the build scripts will replace the empty program with the correct binaries.

Build scripts

Build scripts are in the folder build-scripts.

Minify frontend site:

build-site.sh

Minify app interface:

build-interface.sh

Build Backend:

build-backend.sh

Bundle in a single app:

build-app.sh

Build for both x86 and Apple Silicon

On a Apple M1 computer, first run above scripts in terminal to build the arm version

Rename the following packages:

- components/binaries/ffmpeg to ffmpeg_arm
- components/binaries/lighttpd to lighttpd_arm
- components/backend/dist/main to main_arm

In terminal run

arch -x86_64 /bin/bash

To enable x86 mode and compile again. Rename the following packages:

- components/binaries/ffmpeg to ffmpeg_x86
- components/binaries/lighttpd to lighttpd_x86
- components/backend/dist/main to main_x86

In the folder components/binaries/ run

 lipo -create -output ffmpeg ffmpeg_x86 ffmpeg_arm
 lipo -create -output lighttpd lighttpd_x86 lighttpd_arm

In the folder components/backend/dist/ run

 lipo -create -output main main_x86 main_arm

Sources

In the code we use the following c++ libraries:

Webview

We combine the following libraries
