crtmpserver + ffmpeg

This post will show the process of installing , running and using crtmpserver on ubuntu 64 bit machine with gstreamer .

gcc and cmake

We shall build gstreamer directly from sources . For this we first need to determine if gcc is installed on the machine .

If not installed then  run the following command

GNU Compiler Collection (GCC) is a compiler system produced by the GNU Project supporting various programming languages( C, C++, Objective-C, Fortran, Java, Ada, Go etc).

sudo apt-get install build-essential

once it is isnatlled it can be tested with printing the version

cmake is a software compilation tool.It uses compiler independent configuration files, and generate native makefiles and workspaces that can be used in the differemt compiler environment .

Crtmpserver

To get the source code from git install git first . Then clone the project from https://github.com/j0sh/crtmpserver

sudo apt-get git
git clone https://github.com/j0sh/crtmpserver.git
cd crtmpserver/builders/cmake

Next we create all makefile’s using cmake .

cmake .

Output should look as follows

Run make to do compilation

make

Run using following command . If should print out a list of ports and their respecting functions

./crtmpserver/crtmpserver crtmpserver/crtmpserver.lua

If you the following types of errors while pushing a stream to crtmpserver , they just denote they your pipe is not using the correct format.

ffmpeg

Download and install ffmpeg from git

 git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg

Once the source code is obtained we need to configure , make and make install it .
We need to have following plugins for muxing and ecoding like libx264 for h264parse , so we configure with the following options

./configure \
  --prefix="$HOME/ffmpeg_build" \
  --pkg-config-flags="--static" \
  --extra-cflags="-I$HOME/ffmpeg_build/include" \
  --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
  --bindir="$HOME/bin" \
  --enable-gpl \
  --enable-libass \
  --enable-libfreetype \
  --enable-libopus \
  --enable-libtheora \
  --enable-libvorbis \
  --enable-libx264 \
  --enable-libx265 \
  --enable-nonfree

the make and make install

make
sudo make install

RTMP streaming

1.start the stream from linux machine using ffmpeg

ffmpeg -f video4linux2 -s 320x240 -i /dev/video0 -f flv -s qvga -b 750000 -ar 11025 -metadata streamName=aaa "tcp://<hidden_ip>:6666/live";

3.playback the livestream from another machine

using ffplay
ffplay -i rtmp://server_ip:1935/live/ccc
