  • Changer son thème graphique

    22 février 2011, par

    Le thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.
    Le placement peut être modifié effectivement, mais cette modification n’est que visuelle et non pas au niveau de la représentation sémantique de la page.

  • FFmpeg convert .mov to .ogv

    24 juillet 2016, par Morten Hauberg

    I have some troubles converting my .mov to a .ogg file using FFmpeg.

    This command should work, right ?

    ffmpeg -i test.mov -s 640x320 -vcodec libtheora -acodec libvorbis out.ogv

    It gives me this output

    It seems right, right ?

    But the movie is only about 1 second long.
    Why is that ?

    I do not have access to ffmpeg2theora, so please dont suggest that :)

  • Building FFMPEG library for iOS6.0 ARMv7 Processor

    15 août 2013, par Jimmy

    WARNING :

    I was just informed by another user that there are some legal issues revolving around using FFMPEG for iOS, leaving the link here http://multinc.com/2009/08/24/compatibility-between-the-iphone-app-store-and-the-lgpl/

    I cleaned up my question a little bit, when I wrote it the first time I was flustered. Now I can be more clear after taking a small break.

    Edit : learned that you have to build for ARMv7, ARMv7s and iOS6.0

    I'm trying to use the FFMPEG library in an XCode 4.5.1 project. And I'm trying to build it for ARMv7. What I'm looking for is the exact process, and some explanation. I understand that this is not a well documented problem. But I know that other pople have had the same problem as me.

    What I have been able to do.

    I have been able to build the library for testing.

    1) I have been able to clone ffmpeg. For beginners this will get you started by creating a directory with the ffmpeg source. (Kudos to the guys who wrote it)

    git clone git ://source.ffmpeg.org/ffmpeg.git ffmpeg

    2) I have been able to write a config file that doesn't have any errors. We will go back to this part later. This is the command I attach to ./configure

    ./configure
    —disable-doc
    —disable-ffmpeg
    —disable-ffplay
    —disable-ffserver
    —enable-cross-compile
    —arch=arm
    —target-os=darwin
    —cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2

    —as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2'

    —sysroot=/applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk

    —cpu=cortex-a8
    —extra-ldflags='-arch=armv7 -isysroot /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk'
    —enable-pic —disable-bzlib —disable-gpl —disable-shared —enable-static —disable-mmx —disable-debug —disable-neon —extra-cflags='-pipe -Os -gdwarf-2 -isysroot /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk
    -m$thumb_opt :-no-thumb -mthumb-interwork'

    These are some things to note.

    • I had to download ( https://github.com/yuvi/gas-preprocessor ) copy the file gas-preprocessor.pl at /usr/local/bin. Set permissions to read write (777)
    • Make sure I'm using the right GCC compiler : /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2
    • Make sure I'm using the right SDK : /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk
    • —extra-cflags="-arch armv7" causes : error : unrecognized command line option “-arch”

    Here in lies the problem.

    I can include the library like so

    libavcodec/avcodec.h

    But when I started to write the encoder. I received this warning, and countless errors.

    ignoring file /Users/Jimmy/Development/source.ffmpeg/Library/libavutil.a, file was built for archive which is not the architecture being linked (armv7s) : /Users/Jimmy/Development/source.ffmpeg/Library/libavutil.a

    That means that I didn't build the right binary.

    What I'm looking for is someone whose done it before, to walk all of us through the process of building FFMPEG for iOS6.0 and ARMv7 and the majority of things to look out for. Thanks a ton.
