• FFMPEG 2.5.4 build for Android with NDK r10d

  7 décembre 2015, par jmartinalonso

  I’m trying to build FFmpeg for android following this tuto : http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/

  I’m using :

  • NDK r10d
  • FFMPEG 2.5.4

  I have tried to build on MacOs and Ubuntu and I get the same error when I execute ./build_android.sh :

  `Creating config.mak, config.h, and doc/config.texi...
  
  ./build_android.sh: line 16: --prefix=/Users/jesusmartin92/Documents/android-ndk-r10d/sources/ffmpeg-2.5.4/android/arm: No such file or directory

  ./build_android.sh: line 48: --extra-cflags=-Os -fpic -marm: command not found
  
  ./build_android.sh: line 50: --extra-ldflags=: command not found`

  It’s like the script doesn’t find the ndk folder, but I checked and the path is OK. The script "build_android.sh" is in the ffmpeg folder. This is the content of it :

  #!/bin/bash
  
  NDK=/Users/jesusmartin92/Documents/android-ndk-r10d
  
  SYSROOT=$NDK/platforms/android-9/arch-arm/
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64
  
  function build_one
  
  {
  
  ./configure \
  
      --prefix=$PREFIX \
  
      --enable-shared \
  
      --disable-static \
  
      --disable-doc \
  
      --disable-ffmpeg \
  
      --disable-ffplay \
  
      --disable-ffprobe \
  
      --disable-ffserver \
  
      --disable-avdevice \
  
      --disable-doc \
  
      --disable-symver \
  
      --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
      --target-os=linux \
  
      --arch=arm \
  
      --enable-cross-compile \
  
      --sysroot=$SYSROOT \
  
      --extra-cflags="-Os -fpic $ADDI_CFLAGS" \
  
      --extra-ldflags="$ADDI_LDFLAGS" \
  
      $ADDITIONAL_CONFIGURE_FLAG
  
  make clean
  
  make
  
  make install
  
  }
  
  CPU=arm
  
  PREFIX=$(pwd)/android/$CPU 
  
  ADDI_CFLAGS="-marm"
  
  build_one

  I’m very stuck, so any idea will be well received.

  Thanks

• Some Mp3 Audio Files are not playing

  28 octobre 2014, par Ramesh Karanam

  When Playing mp3 Audio Files some songs are playing successfully but some songs are not playing.When decoding audio file getting error like No Data found when processing input.

  dec_ctx = fmt_ctx->streams[audio_stream_index]->codec;

  Finding Audio Stream :

  audio_st = fmt_ctx->streams[audio_stream_index];

  Finally I am Decoding Audio

  if (packet.stream_index == audio_stream_index)
  
              {
  
                  frame = avcodec_alloc_frame();
  
                  avcodec_get_frame_defaults(frame);
  
                  got_frame = 0;
  
                  ret = avcodec_decode_audio4(dec_ctx, frame, &got_frame, &packet);
  
  }

  Here avcodec_decode_audio4 returns the negative value when printing error it shows Inavalid Data Found When Processing input.

  I am Using ffmpeg 2.0.1 My configure options are

   --prefix=$PREFIX \
  
      --enable-shared \
  
      --enable-static \
  
      --enable-doc \
  
      --enable-ffmpeg \
  
      --enable-ffplay \
  
      --enable-ffprobe \
  
      --enable-ffserver \
  
      --enable-avdevice \
  
      --enable-doc \
  
      --enable-symver \
  
      --enable-swresample\
  
      --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
      --target-os=linux \
  
      --arch=arm \
  
      --enable-cross-compile \

  I am not understanding whats the problem ?code or any modifications required in ffmpeg configure file.Please Provide any information about this issue.
