  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • ffmpeg mp3 encoder : how to set exactly 8.00 kbps bitrate

    18 novembre 2022, par al.zatv

    I want to produce constant-bitrate mp3 with bitrate 8.00kbps. I use this :
ffmpeg -i q.wav -b:a 8k q.mp3

    


    But,instead of creating 8.00 kbps mp3, it creates 8.40 kbps file (or 8.41 or like that), as soxi informs :

    


    Channels : 1
Sample Rate : 8000
Precision : 16-bit
Duration : 00:00:05.11 = 40896 samples 383.4 CDDA sectors
File Size : 5.37k
Bit Rate : 8.41k
Sample Encoding : MPEG audio (layer I, II or III)

    


    But I need 8.00 bitrate ! I can easily produce it with sox q.wav -C 8 q.sox.mp3
Bit Rate : 8.41k

    


    How can I force ffmpeg produce mp3s with 8.00 k bitrate exactly ?

    


  • Complie FFMpeg with Xcode5 preview's clang

    2 août 2013, par Yeung

    With release of IOS7 beta, I would like to try compiling ffmpeg for ios7.

    There is a lots answer like this. It use the llvm-gcc as compiler.

    However, seem like Xcode 5 would not include llvm-gcc. Then I have no choice but to use clang to compile.

    I use the following to config :

    export IOS_SDK="/Applications/Xcode5-DP4.app/Contents/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk"
    

    
./configure $CONFIG_DISABLE_FLAG $CONFIG_ENABLE_FLAG \
    
--arch=arm \
    
--target-os=darwin \
    
--cc=/Applications/Xcode5-DP4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang \
    
--as='gas-preprocessor.pl /Applications/Xcode5-DP4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang' \
    
--ar=/Applications/Xcode5-DP4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar  \
    
--sysroot=$IOS_SDK \
    
--cpu=cortex-a8 \
    
--extra-cflags="-arch armv7 -mfpu=neon -mfloat-abi=softfp -ftree-vectorize -ffast-math -funsafe-math-optimizations -fsingle-precision-constant -isysroot ${IOS_SDK} -I${IOS_SDK}/usr/include" \
    
--extra-ldflags="-arch armv7 -mfpu=neon -mfloat-abi=softfp -ftree-vectorize -ffast-math -funsafe-math-optimizations -fsingle-precision-constant -isysroot ${IOS_SDK} -L${IOS_SDK}/usr/lib" \
    
--enable-pic

    clang would probably not take CFLAGS other than -arch  -isysroot -I into account, but let it be.

    I seems it can complie but I encounter this. Actually, I don't understand the answer in this question. Using the external assembler ? Yes, the toolchains do have a assembler stated it is GNU version 1.38. Using --as=/Application/Xcode5-DP4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/as, it even cannot pass the check as test. It fall back to use 'gas-preprocessor.pl $CC'

    Here is the config log to cannot pass :

    Yep, with config --disable-asm would complie but it probably not a option.
