• PHP Convert image+audio = video

  31 octobre 2014, par jQuery Angry Bird

  Hi I saw THIS Question.There is no proper rather vague answer.

  He said ffmpeg -r 10 -b 1800 -i %03d.jpg test1800.mp4 .Pretty vague.

  What i want is I have 2 inputs i wil give from php file . Image,Audio ,And Output will be Video .
  I saw people saying ffmpeg And all that .But does it/can it convert Image+Audio to Video ??
  If yes then what should be done ?? I saw lots of questions .but NONE of then answers properly.I didnt see ANY PHP code to do so online.Thanks.

• MP3 Audio requiring overlays at specific intervals to ensure I dont break copyright rules

  15 novembre 2012, par user1828008

  I have started a project as a DJ to record my online radio shows to mp3. The station I play on is licenced so I am not breaking any copyright rules there. I have had the idea to upload the recordings onto Youtube.

  Clearly that needed some form of adjustment to make a video over the top of the audio which I have achieved using ffmpeg so I have an mp4 file with a picture overlay for the duration of the audio. I did a quick test run to upload the video to Youtube and it tracked that I was playing copyrighted material. It was exactly right in its statement and yes as my own channel on youtube I am not licenced to do so. Either way I have spoke to the copyright owners and they have agreed it is fine.

  However in order to not have to do this every week if I overlay a 5 second 'jingle' every 4 minutes over the audio (fading down if possible) the main volume slightly to play the jingle and fade up after (once again if possible) then I am 100% in the clear. I could do this manually but would rather something I can script in bash to do it for me.

  I am using Centos 6.3 operating system and FFMPEG solved the merge of video and audio together, but I couldnt find anything to do a predefined audio overlay at specific intervals.

  I have looked at programs like Avisynth and Sox but dont believe from the documentation that they have anything that can do regular interval overlays during a single track. The closest thing I could find is on this post :

  Add multiple audio files to video at specific points using FFMPEG

  But it would be nice to do everything in a single sweep with ffmpeg of the audio file (video and audio overlay) if thats possible somehow or any better options that are out there ?

  If you need any more info from me then please let me know.
  Thanks

• Compile FFMPEG + x264 - undefined references

  18 juin 2013, par Tishu

  I have been trying to find a solution online for a couple of days with no luck. I am using Ubuntu and trying to compile the latest FFMPEG stable version (1.0.1) with x264 support. I made sure I uninstalled any existing x264 then I downloaded the latest x264 source and compiled it with the following config :

  ./configure --prefix=$PREFIX \
  
      --enable-shared \
  
      --enable-static \
  
      --disable-gpac \
  
      --extra-cflags=" -I$ARM_INC -fPIC -DANDROID -fpic -mthumb-interwork -ffunction-sections -funwind-tables -fno-short-enums -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__ -Wno-psabi -march=armv5te -msoft-float -mthumb -Os -fomit-frame-pointer -fno-strict-aliasing -finline-limit=64 -DANDROID -Wa,--noexecstack -MMD -MP " \
  
      --extra-ldflags=" -nostdlib -Bdynamic -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,nocopyreloc -Wl,-soname,/usr/lib/libz.so -Wl,-rpath-link=$ARM_LIB,-dynamic-linker=/system/bin/linker -L$ARM_LIB -lc -lm -ldl -lgcc" \
  
      --cross-prefix=${ARM_PRE}- \
  
      --disable-asm \
  
      --host=arm-linux \
  
  
  
      make clean
  
      make install

  All goes well, and I checked the installed version :

  x264 -V
  
      x264 0.129.x
  
      built on Dec 27 2012, gcc: 4.6.1
  
      configuration: --bit-depth=8 --chroma-format=all
  
      x264 license: GPL version 2 or later

  I then try to compile FFMPEG with the following options :

  ./configure --target-os=linux \
  
      --enable-libx264 \
  
      --enable-gpl \
  
      --prefix=$PREFIX \
  
      --extra-cflags="-I/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/ffmpeg-1.0.1/android/armv7-a/include -I/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/x264 -O3 -fpic -DANDROID -DHAVE_SYS_UIO_H=1 -Dipv6mr_interface=ipv6mr_ifindex -fasm -Wno-psabi -fno-short-enums  -fno-strict-aliasing -finline-limit=300 $OPTIMIZE_CFLAGS " \
  
      --extra-ldflags="-Wl,-rpath-link=$PLATFORM/usr/lib -L/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/ffmpeg-1.0.1/android/armv7-a/lib -L$PLATFORM/usr/lib -nostdlib -lc -lm -ldl -llog" \
  
      --enable-cross-compile \
  
      --extra-libs="-lgcc" \
  
      --arch=arm \
  
      --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
  
      --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
  
      --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
  
      --sysroot=$PLATFORM \

  The configure and make clean/make install work well, but when I try to create the .so file the following command fails :

  /home/tishu/Apps/android-ndk-r8d/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ld

      --warn-once \
  
      --dynamic-linker=/system/bin/linker /home/tishu/Apps/android-ndk-r8d/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/lib/gcc/arm-linux-androideabi/4.4.3/libgcc.a

  This fails with the following output :

  libavcodec/libavcodec.a(libx264.o): In function `X264_frame':

  The x264 version it is looking for (129) is the one installed and compiled succesfully with —eanable-shared. Obviously all compiles fine when I do not include libx64.

  Question : How can I specify the include path for the last command ? I tried adding the path to $PATH and also adding this as an argument with no luck : -I/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/x264

  Thanks
