  • Use ffmpeg to stream live content to azure media services

    9 juin 2016, par Dadicool

    I’ve been trying to stream content to azure media services using ffmpeg as it’s one of the options described here : http://azure.microsoft.com/blog/2014/09/18/azure-media-services-rtmp-support-and-live-encoders/

    My command is :

    ffmpeg -v verbose -i 300.mp4 -strict -2 -c:a aac -b:a 128k -ar 44100 -r 30 -g 60 -keyint_min 60 -b:v 400000 -c:v libx264 -preset medium -bufsize 400k -maxrate 400k -f flv rtmp://nessma-****.channel.mediaservices.windows.net:1935/live/584c99f5c47f424d9e83ac95364331e7

    I have made sure that the streaming endpoint has one active streaming unit, I also made sure that the channel is actually Ready and I even get it to start streaming (which makes a PublishURL available).

    When I execute the ffmpeg command to start streaming, I keep getting the following error :

    The Azure blog post clearly states that this should be possible but I can’t find a working example anywhere.

    Environment :

    • MacOS Maverick
    • FFMPEG installed from official build
    • 300.mp4 : 1080p trailer of the latest 300 movie

  • Enabling libmp3lame for FFMPEG on elastic beanstalk

    13 octobre 2017, par Adam Sith

    I am trying to enable libmp3lame with FFMPEG in elastic beanstalk (Amazon Redhat Linux machine).

    I am able to successfully install FFMPEG in /ffmpeg.config with the following script :

    # .ebextensions/ffmpeg.config
    

    
packages:
    
  yum:
    
    autoconf: []
    
    automake: []
    
    cmake: []
    
    freetype-devel: []
    
    gcc: []
    
    gcc-c++: []
    
    git: []
    
    libtool: []
    
    make: []
    
    nasm: []
    
    pkgconfig: []
    
    zlib-devel: []
    
sources:
    
  /usr/local/src: http://ffmpeg.org/releases/ffmpeg-3.2.tar.bz2
    
commands:
    
  ffmpeg_install:
    
      cwd: /usr/local/src/ffmpeg-3.2
    
      command: sudo ./configure --prefix=/usr && make && make install

    I need to install libmp3lame however. I’ve tried to do this with an --enable-libmp3lame flag and the directions here. The modified script :

    packages:
    
yum:
    
    autoconf: []
    
    automake: []
    
    cmake: []
    
    freetype-devel: []
    
    gcc: []
    
    gcc-c++: []
    
    git: []
    
    libtool: []
    
    make: []
    
    nasm: []
    
    pkgconfig: []
    
    zlib-devel: []
    
sources:
    
  /usr/local/src: http://ffmpeg.org/releases/ffmpeg-3.2.tar.bz2
    
commands:
    
  01-install_libmp3lame:
    
      cwd: /usr/local/src/
    
      command: curl -L -O http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz && tar xzvf lame-3.99.5.tar.gz && cd lame-3.99.5 && ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --disable-shared --enable-nasm && make && make install
    
  02-ffmpeg_install:
    
      cwd: /usr/local/src/ffmpeg-3.2
    
      command: sudo ./configure --enable-libmp3lame && --prefix=/usr && make && make install

    This doesn’t work. Command 01-install_libmp3lame completes. Command 02-ffmpeg_install fails because :

    [2017-10-12T20:55:19.324Z] INFO  [24606] - [Application update app-8fe3-123456_7895@111/AppDeployStage0/EbExtensionPreBuild/Infra-EmbeddedPreBuild/prebuild_3_clover_platform/Command 02-ffmpeg_install] : Activity execution failed, because: ERROR: libmp3lame >= 3.98.3 not found

    I have tried installing libmp3lame in /ffmpeg-3.2 and got the same issue.

  • java.lang.NoClassDefFoundError : Could not initialize class on Linux (Works fine on Windows)

    26 décembre 2016, par Jake Miller

    I’m using a C++ FFmpeg wrapper for Java (org.bytedeco.javacpp). This works perfectly on a Windows machine (my development machine) but throws this error when ran on Linux (Amazon Web Services Elastic Beanstalk) :

    java.lang.NoClassDefFoundError: Could not initialize class org.bytedeco.javacpp.avutil
    
    at java.lang.Class.forName0(Native Method) ~[na:1.8.0_111]

    at org.bytedeco.javacv.FFmpegFrameGrabber.start(FFmpegFrameGrabber.java:385) ~[javacv-1.3.jar!/:1.3]
    
</clinit>

    I’ve been troubleshooting for the past 2 days and have tried the following to fix the issue :

    • upgrade to Linux to 2.4
    • downgrading javacpp to 1.2.1
    • running mvn clean
    • running mvn -U
    • deleting contents of /.m2/ and redownloading dependencies
    • various combinations of dependency versions
    • git clone on a Linux VM & running mvn install there

    When looking further into the issue, I stumbled upon documentation for avformat$AVFormatContext as it’s in the stack trace posted above (6th line). The documentation for a C++ class named AVFormatContext. Whenever I attempt to view the class in Eclipse, it says Source Not Found.

    My question : could this problem possibly be caused by the C++ libraries on my Linux VM ? None of the above solutions fixed it so this is my only hypothesis as of now.

    Here’s my other Stack Overflow question regarding this subject : Java.lang.NoClassDefFoundError caused by FFmpeg when deployed on Linux as a packaged .war (Works on development machine)
