• FFmpeg Ubuntu linker error

  29 mars 2016, par CodeDezk

  I am trying to decode audio using ffmpeg lib and c++ from Ubuntu 12.04. I am following the code here https://0xdeafc0de.wordpress.com/2013/12/19/ffmpeg-audio-playback-sample/

  Below is the command used to compile the code

  g++ -std=c++11 decode_play_audio.cpp -I/home/codeDev/ffmpeg_sources/build_Mar-10-2016/include -L/home/codeDev/ffmpeg_sources/build_Mar-10-2016/lib  -lavcodec -lavformat -lavutil

  But getting the compile error as below,

  I have build latest ffmpeg 3.0 and located at /home/codeDev/ffmpeg_sources/build_Mar-10-2016/

  And I can see all the libs located at /home/codeDev/ffmpeg_sources/build_Mar-10-2016/lib

    libavcodec.a
  
    libavfilter.a
  
    libavutil.a
  
    libswresample.a
  
    pkgconfig
  
    libavdevice.a
  
    libavformat.a
  
    libpostproc.a
  
    libswscale.a

• ffmpeg compilation with —arch=x86_64 always compiles with x86

  31 juillet 2019, par Guerlando OCs

  I’m compiling ffmpeg with

  ./configure \
  
        --prefix=${BUILD_DIR}/desktop/${ARCH} \
  
        --extra-cflags="-I$HOME/ffmpeg_build/include" \
  
        --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
  
        --enable-shared \
  
        #--extra-cflags="-I/opt/intel/mediasdk/include" \
  
        #--extra-ldflags="-L/opt/intel/mediasdk/lib" \
  
        #--extra-ldflags="-L/opt/intel/mediasdk/plugins" \
  
        --arch=${ARCH} \
  
        --enable-libmfx \
  
        --enable-vaapi \

        --enable-pic \
  
        --extra-libs="-lpthread -libm -libc -lz -ldl" \
  
        --enable-nonfree 

  where ARCH=x86_64 but it always gives me this in the output of configure :

  install prefix            /home/deps/ffmpeg/build/desktop/x86_64
  
  source path               .
  
  C compiler                gcc
  
  C library                 glibc
  
  ARCH                      x86 (generic)
  
  ...

  uname -m says my machine is x86_64 so I’m not trying to build on a x86 only.

  What is happening ?

• Android with pthread_cancel enabled ? ffmpeg depends on pthread_cancel

  12 mars 2014, par Whoami

  I am building ffmpeg 2.1.3 in the android with ndk r9b version.

  I have used the below command.

  ./configure --enable-shared --prefix=/home/fbuild 
  
               --cross-prefix=arm-linux-androideabi- 
  
               --enable-cross-compile

               --cpu=cortex-a8 
  
               --enable-pthreads --enable-static

  in config.log

   main:ffconf.82qqjSTF.c(.text+0x4): error: undefined reference to '**pthread_cancel**

  Which clearly indicates, pthread_cancel is unavailable.

  Is it an existing issue, or do we have a any other solution for the same ?

  I have enabled '—enable-pthreads',

  I am trying to stream RTSP Stream through, UDP

  Your help is much appreciated. Thanks.
