Problème de compilation de l'iPhone SDK 4.3 libav

Question

J'ai été confronté à un étrange problème. J'ai installé iPhone SDK 4.3 et xCode 4 et maintenant je ne peux pas compiler libav de ffmpeg pour l'architecture ARMv6. Voici mon script pour le compiler (il fonctionne bien pour iPhone SDK 4.2) :

./configure \
--disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile \
--enable-encoder=rawvideo \
--enable-decoder=h264 \
--enable-decoder=mpeg4 \
--enable-encoder=mjpeg \
--enable-muxer=rawvideo \
--enable-demuxer=h264 \
--enable-parser=h264 \
--enable-cross-compile \
--arch=c \
--target-os=darwin \
--enable-libopencore-amrnb --enable-libopencore-amrwb \
--cc=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1 \
--as='gas-preprocessor/gas-preprocessor.pl /Developer/Platforms/iPhoneOS.platform/Developer    /usr/bin/arm-apple-darwin10-gcc-4.2.1' \
--sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk \
--cpu=arm1176jzf-s --extra-cflags='-arch armv6' --extra-ldflags='-arch armv6'

make clean
make   

Le résultat est que j'obtiens des fichiers de bibliothèque mais lorsque je les vérifie avec la commande lipo -info, il apparaît que la bibliothèque a été compilée pour l'architecture i386.

Peut-être que quelqu'un a été confronté à ce problème ? Aidez-moi, s'il vous plaît.

Merci.

Mise à jour

Voici une mise à jour du script qui supprime armv6, ajoute armv7s, utilise le SDK iOS 6.0 et corrige les problèmes liés aux modifications apportées au lipo outil. Assurez-vous d'avoir la dernière gas-preprocessor.pl de github en /usr/local/bin :

Ceci va construire les bibliothèques statiques de ffmpeg pour les architectures armv6, armv7 et i386 et les combiner en fichiers fat (universels) pour iOS 4.3 (iPhoneOS4.3 et iPhoneSimulator4.3) :
