• First input link main timebase (1/15360) do not match the corresponding second input link xfade timebase (1/90000)

  I am new to ffmpeg and i am facing this error for more then 2 days.
This ffmpeg command :
!ffmpeg -i "{fromPath}" -i "{toPath}" -filter_complex "xfade=transition={chosenTransition}:duration={transitionDuration}:offset=-1.5" -c:v libx264 -crf 18 -preset veryfast "{outPath}"
I run that previous command 3 times in row where output of the previous command is input that is getting produced as 15360 timebase video i guess.

  


  is giving me this error : "First input link main timebase (1/15360) do not match the corresponding second input link xfade timebase (1/90000)"

  


  So when i merge two of my videos the output is video with (1/15360) timebase. Original videos has (1/90000) timebase.

  


  Pls help what i wana archive is basicly multiple videos inside a folder called "clips" merge together using a random transition from xfade/ffmpeg.

  


  On colab i tried all this ways :

  


  !rm -rf chunks
!mkdir chunks
time.sleep(1)
folderPath = '/content/clips'
videoOutput = '/content/test.mp4'
transitionDuration = 6

videoFiles = [f"{folderPath}/{f}" for f in os.listdir(folderPath) if f.endswith('.mp4')]
random.shuffle(videoFiles)
fromPath = videoFiles[0]
toPath = ''
outPath = ''
transitions = ['fade', 'wipeup', 'slidedown', 'circleclose', 'radial' , 'hrslice', 'hblur', 'smoothleft', 'smoothright']

for videoIndex, videoName in enumerate(videoFiles):
    if videoIndex == 0:
        continue
    toPath = videoName
    chosenTransition = random.choice(transitions)
    print('chosenTransition', chosenTransition)
    clipDuration = int((imageio.get_reader(fromPath)).get_meta_data()['duration']) - transitionDuration
    # !echo -i /content/clips/clip0.mp4 -i /content/clips/clip1.mp4 -filter_complex xfade=transition={chosenTransition}:duration=3:offset={clipDuration} dissolveVideo.mp4

    if videoIndex == len(videoFiles) - 1:
        outPath = videoOutput
    else:
        outPath = f'/content/chunks/chunk{videoIndex}.mp4'
    time.sleep(2)
    
    # !echo -i "{fromPath}" -i "{toPath}" -filter_complex "[0:v]xfade=transition={chosenTransition}:duration=3:offset={clipDuration},settb=1/19000[v0];[0:a][1:a]acrossfade=d=3[aout]" -map "[v0]" -map "[aout]" -c:v libx264 -crf 18 -preset ultrafast "{outPath}"
    !ffmpeg -i "{fromPath}" -i "{toPath}" -filter_complex "xfade=transition={chosenTransition}:duration={transitionDuration}:offset=-1.5,settb=1/15360" -c:v libx264 -crf 18 -preset veryfast "{outPath}"

• Evolution #3958 (Nouveau) : Mise à jour de la liste des types mines

  12 juin 2017, par Franck D

  Hello, après lecture de http://www.clubic.com/pro/entreprises/apple/actualite-831758-apple-finir-jpeg.html :-(
  Je propose de mettre à jour les types mines https://zone.spip.org/trac/spip-zone/browser/_core_/plugins/medias/base/typedoc.php de la médiathèque pour le support de ce type, car il y a des chances que des utilisateurs l’utilisent :-((
  Le type mine "semble" être dans ce document : http://nokiatech.github.io/heif/technical.html

  Il y a sans doute des formats libres dont il faudrait faire l’ajout, comme http://www.numerama.com/tech/259437-videolan-vlc-se-mobilise-contre-les-codecs-payants-et-proprietaires.html mais je ne sais pas comment faire pour mettre la main sur les infos :-(

• Error when compiling FDK-AAC for iOS

  1er juillet 2014, par 谢小进

  I want to compile FDK-AAC for iOS, including i386, x86_64, armv7, armv7s, arm64. I use this shell script and run, only i386, x86_64, armv7, armv7s are built. Code like this :

  #!/bin/sh
  
  
  
  # OS X Mavericks, Xcode 5.1
  
  
  
  set -ex
  
  
  
  VERSION="0.1.3"
  
  CURRPATH=`pwd`
  
  SOURCE="fdk-aac-$VERSION"
  
  DSTDIR="libfdk-aac"
  
  SDKVERSION="7.1"
  
  ARCHS="x86_64 i386 armv7 armv7s"
  
  DEVELOPER="/Applications/Xcode.app/Contents/Developer"
  
  
  
  rm -rf $DSTDIR
  
  mkdir $DSTDIR
  
  
  
  tar jxf $SOURCE.tar.gz
  
  cd $SOURCE
  
  
  
  for ARCH in $ARCHS; do
  
      mkdir -p $CURRPATH/$DSTDIR/$ARCH
  
  
  
      if [ $ARCH == "i386" -o $ARCH == "x86_64" ]; then
  
          PLATFORM="iPhoneSimulator"
  
          HOST=
  
          if [ $ARCH = "i386" ]; then
  
              HOST="--host=i386-apple-darwin"
  
          fi
  
      else
  
          PLATFORM="iPhoneOS"
  
          HOST="--host=arm-apple-darwin"
  
      fi
  
  
  
      SDK="$DEVELOPER/Platforms/$PLATFORM.platform/Developer/SDKs/$PLATFORM$SDKVERSION.sdk"
  
      IOSMV="-miphoneos-version-min=7.0"
  
      export CC="$DEVELOPER/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang"
  
      export CFLAGS="$IOSMV -arch $ARCH"
  
      export LDFLAGS="$IOSMV -arch $ARCH -isysroot $SDK"
  
      export LIBS="-L$SDK/usr/lib"
  
      export CXXFLAGS="$IOSMV -arch $ARCH -I$SDK/usr/include"
  
  
  
      ./configure \
  
      $HOST \
  
      --with-sysroot="$SDK" \
  
      --prefix=$CURRPATH/$DSTDIR/$ARCH
  
  
  
      make && make install && make clean
  
  done
  
  
  
  cd ..
  
  mkdir -p $DSTDIR/lib
  
  
  
  lipo -create `find $DSTDIR -name libfdk-aac.a` -output $DSTDIR/lib/libfdk-aac.a
  
  
  
  cp -rf $DSTDIR/$ARCH/include $DSTDIR
  
  
  
  for ARCH in $ARCHS; do
  
      rm -rf $DSTDIR/$ARCH
  
  done

  Can somebody tell me why arm64 is not built correct ? If needed, where can I change them ? Maybe it could be like -host= value. but I have used -host=arm-apple-darwin, and -host=arm64-apple-darwin, it’s not correct either.
