• 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 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

• FFMPEG Audio and Video Streams merging and restreaming

  2 novembre 2015, par Brandon

  I have multiple streaming sources that need to combined and re-streamed as a single source.

  My sources are :

  • A local low rate RTP audio stream
  • A camera

  I need to redistribute the combined stream (via UDP multicast) across the local network.

  The problem I am seeing is that periodically ffmpeg appears to lock up and stop processing the combination after an indeterminate amount of time (sometimes as little as 15 min sometimes almost an hour). However if I redirect the streams independently (audio or video only) there appears to be no problem and the run indefinitely.

  Command

  ffmpeg -f rtp -i rtp://127.0.0.1:6666 -f video4linux2 -standard NTSC -s 704x480 -i /dev/video1 -strict experimental -vcodec libx264 -acodec ac3 -preset ultrafast -r 3 -g 3 -keyint_min 6 -x264opts "keyint=6:min-keyint=6:no-scenecut" -b:v 200k -ac 1 -b:a 64k -f mpegts udp://225.1.1.15:30000
