  • FFmpeg "Unrecognized option" error when trying to merge 2 audio files in Android

    20 mars 2017, par Sha

    Looked at This and This links to create a command to merge 2 audio files using ffmpeg but it’s not working.

    My command :

    String input1 = "/storage/emulated/0/jd.m4a "; 
    
String input2 = "/storage/emulated/0/jd.m4a "; //trying with same audio just to check if it works or not
    
String filter = "-filter_complex [0:a]volume=0.99[a1];[1:a]volume=0.3[a2];[a1][a2]amerge=inputs=2,volume=1.3,pan=stereo|c0code>

    The console output :

    From what I can understand is that ffmpeg is unable to split and differentiate the inputs, filter and output from the command, but I tried with a lot of variations, still not working :(

    Please help. Looked around a lot but none of the commands is working.

    Thanks in advance !

    EDIT :
    Added -report before -filter_complex and ran. LOG is below AS @Mulvya asked

  • No output file when converting audio using FFmpeg in Android

    18 mars 2017, par Sha

    I’m trying to convert m4a audio file to wav using FFmpeg. The code executes fine and gives no error, but I don’t see any output file in my directory.

    This is what I am executing :

    String[] cmd = {"-y", "-i", "/storage/emulated/0/jd.m4a", "-f","wav" ,"/storage/emulated/0/DCIM/Camera/output.wav"};

    And this is what gets printed :

  • Compiling x264 on a Mac : "No working C compiler found" and "arm-linux-androideabi-gcc : command not found"

    29 novembre 2014, par Xavi Gil

    I am trying to compile the x264 library for Android, following this post.

    I have cloned the x264 project git clone git://git.videolan.org/x264.git and tried to compile with the following configuration :

    NDK=~/development/android-ndk-r10c    
    
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64
    
PLATFORM=$NDK/platforms/android-21/arch-arm
    

    
./configure \
    
--cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
    
--sysroot=$PLATFORM \
    
--host=arm-linux \
    
--enable-pic \
    
--enable-static \
    
--disable-cli

    The problem is that I get a No working C compiler found. error.

    The conftest.log output :

    $ cat conftest.log 
    
./configure: line 153: arm-linux-androideabi-gcc: command not found

    But the arm-linux-androideabi-gcc is the toolchain’s bin folder !!

    Looking at this other question it looks like for some reason, even though the file exists, since it is a 64bit Mac, it won’t execute the arm-linux-androideabi-gcc file and will return this weird error and log.

    I am in a Mac OS X 10.10 and I have installed the XCode Command Line Tools :

    $ xcode-select -p
    
/Applications/Xcode.app/Contents/Developer

    GCC version :

    $ gcc --version
    
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
    
Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)
    
Target: x86_64-apple-darwin14.0.0
    
Thread model: posix

    Can anyone tell me how to fix this please ?
