At present, I'm using x264 for my streaming application. I would like to<br>
upgrade it to HEVC encoder as my clients have the HEVC decoder support. Is<br>
the open source implementation of HEVC started ? Can anyone share when will<br>
it be ready ?<br>

<br>
Greeting!<br>
<br>
I would like to share with some compilation problem while I was prepared libx264.a. Then I was linked libx264 with the ffmpeg compilation and meat some problem.<br>
<br>
All Steps:<br>
<br>
1. Source downloading of the libx264<br>
<br>
> git clone git://<a href="http://git.videolan.org/x264.git" target="_blank">git.videolan.org/x264.git</a><br>
<br>
2. Compiling libx264 for iOS (let's say it will be for armv7s)<br>
<br>
> CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc ./configure \<br>
--host=arm-apple-darwin \<br>
--sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk \<br>
--prefix=armv7s \<br>
--extra-cflags="-arch armv7s -mcpu=cortex-a9" \<br>
--extra-ldflags="-arch armv7s -L/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/usr/lib/system" \<br>
--enable-static \<br>
<br>
On that step I have compiled library and includes. Compiles library I was copy to the /usr/local/lib and includes I was copy to the /usr/local/include<br>
<br>
3. Source downloading of the ffmpeg<br>
<br>
> git clone git://<a href="http://source.ffmpeg.org/ffmpeg.git" target="_blank">source.ffmpeg.org/ffmpeg.git</a> ffmpeg<br>
<br>
4. Some preparation for ffmpeg compilation<br>
<br>
- Installing mac ports (if not installed)<br>
- Installing pkgconfig (> sudo port install pkgconfig)<br>
- Downloading <a href="http://gas-preprocessor.pl" target="_blank">gas-preprocessor.pl</a> and copy it to the /usr/local/bin<br>
- Then change permitition for <a href="http://gas-preprocessor.pl" target="_blank">gas-preprocessor.pl</a> (> chown 777 /usr/local/bin/<a href="http://gas-preprocessor.pl" target="_blank">gas-preprocessor.pl</a>)<br>
<br>
So for now we are ready to compile and install ffmpeg with libx264<br>
<br>
5. Compiling and installing ffmpeg<br>
<br>
> ./configure \<br>
--prefix=armv7s \<br>
--disable-ffmpeg \<br>
--disable-ffplay \<br>
--disable-ffprobe \<br>
--disable-ffserver \<br>
--enable-avresample \<br>
--enable-cross-compile \<br>
--sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk" \<br>
--target-os=darwin \<br>
--cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" \<br>
--extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=6.0 -I/usr/local/include" \<br>
--extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk -miphoneos-version-min=6.0 -L/usr/local/lib" \<br>
--arch=arm \<br>
--cpu=cortex-a9 \<br>
--disable-asm \<br>
--enable-libx264 \<br>
--enable-gpl \<br>
<br>
> make clean && make && make install<br>
<br>
The main thing here is --enable-libx264 option and paths to the libx264 in --extra-cflags and --extra-ldflags<br>
<br>
6. Putting all together<br>
<br>
- Create new Xcode project<br>
- Copy libraries from libx264 to the project<br>
- Copy libraries from ffmpeg to the project<br>
- In the project in the AppDelegate.m file in method didFinishLaunchingWithOptions I added one ffmpeg call avcodec_register_all();<br>
<br>
After running the project I found one warning from XCode<br>
<br>
PIE disabled. Absolute addressing (perhaps -mdynamic-no-pic) not allowed in code signed PIE, but used in l070 from /Users/aukuzmin/Projects/x264/h264/lib/libx264.a(pixel-a.o). To fix this warning, don't compile with -mdynamic-no-pic or link with -Wl,-no_pie<br>
<br>
<br>
I was trying to find out what's going on and I found next thing. When I was configuring libx264 it is compiling with -mdynamic-no-pic flag. I opened configure file and made next:<br>
<br>
And after that I compiled libx264 one more time copied lib to the /usr/local/lib and compiled ffmpeg one more time. Then copy compiled libs to the Xcode and run the demo project.<br>
So warning wash't dismiss.<br>
<br>
So my question is:<br>
<br>
How can I compile libx264 without any warning?<br>
<br>
P.S. My system is OS X 10.8.2, Xcode 4.5.2, iOS SDK 6.0<br>
<br>
Thank you,<br>
Alexey<br>
