  • accelerate x264 encoding

    7 août 2012, par Saraswati

    i am making use of x264 to encode raw data captured from the iphone camera .. but the encoding is very slow .Can anyone help me accelerate the encoding speed.

    I have used following settings to build x264 lib :

    //for armv6

    CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc ./configure —host=arm-apple-darwin —sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk —prefix='dist' —extra-cflags='-arch armv6' —extra-ldflags=-L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/lib/system/ —extra-ldflags='-arch armv6' —enable-pic —disable-asm

    //for armv7

    CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc ./configure —host=arm-apple-darwin —sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk —prefix='dist' —extra-cflags='-arch armv7' —extra-ldflags=-L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/lib/system/ —extra-ldflags='-arch armv7' —enable-pic

    I am using default preset like this :

    x264_param_default_preset(param, "slow", "zerolatency");

    and setting few perameters :

    param->i_bframe = 0;
    
param->analyse.i_me_method = X264_ME_HEX;
    
param->analyse.i_subpel_refine = 2;
    
param->i_frame_reference = 1;
    
param->analyse.b_mixed_references = 0;
    
param->analyse.i_trellis = 0;
    
param->rc.b_mb_tree = 0;
    
param->analyse.i_weighted_pred = X264_WEIGHTP_NONE;
    

    

    
param->rc.i_bitrate = 180;
    
param->rc.i_qp_min = 20; 
    
param->rc.i_qp_max = 26; 
    

    
param->i_keyint_max = 15; 
    
param->i_keyint_min = 15;
    

    

    
param->i_width = w;
    
param->i_height = h;
    

    
x264_param_apply_profile(param, "baseline");
    
x264_picture_alloc( &(enc->pic), X264_CSP_I420, param->i_width, param->i_height );

  • iFrameExtractor fails to build library for armv7 using XCode 4.3.3 & iOS 5.1

    16 mars 2013, par Rajat Lala

    I have downloaded code to build with XCode 4.3.3 for iOS 5.1 from this link - https://github.com/lajos/iFrameExtractor
    I am successfully able to build the libraries for FFmpeg using build_universal script. But it always builds the libraries for X86_64 architecture. Checked with lipo -info command.

    Also tried the build script from the link - http://stexgroup.com/blog/ffmpeg-for-iphone-ios-xcode4.3-build-script. It also builds libraries for X86_64 architecture.

    I changed the scripts as per this post - problem compiling ffmpeg for iFrameExtractor

    But nothing is working for me.

    The build script for armv7 [iFrameExtractor] is as following

    ./configure \
    
--disable-bzlib --disable-doc \
    
--disable-ffmpeg --disable-ffplay \
    
--disable-ffserver --disable-mmx \
    
--cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc \
    
--as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' \
    
--enable-cross-compile --target-os=darwin \
    
--arch=arm --cpu=cortex-a8 --enable-pic \
    
--sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk \
    
--extra-ldflags="-arch armv7 -    L//Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/usr/lib" \
    
--extra-cflags="-arch armv7"

    Can anybody guide me what can be the issue, considering the same thing is working for everyone else ?
