Hi kewlbear,
Thank you very much for entire explanation to set up FFmpeg for iOS. I followed each step and successfully installed everything. I have a problem that i have to convert .h264 file to .mp4. Here is my question I have a .h264 file in my xcode project bundle, i have to convert the file in to .mp4, how to do this programmatically using this FFmpeg in Xcode?
Please give any suggestions or any snippet of code.

Thank you.

i use the build-fdk-aac.sh(ARCHS="armv7 x86_64 i386")/build-ffmpeg.sh(ARCHS="x86_64 i386 armv7") compile success,but i copy the fdk-aac-ios to subdir of FFmpeg-iOS-build-script-master,it occurs error:

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

what is up ?

When FFmpeg is built successfully, a folder "scratch" will be generated, the files in it are related files?

I put the script file and ffmpeg source in the same folder, after run it , there is a warning .

I have also added the required frameworks, but still same error! can you please suggest what could have went wrong?

Thanks.

I have an app, In which I am decoding video frames coming from ip camera, but the method avcodec_decode_video2(m_pCodecCtx, m_pFrame, &consumed_bytes, &avpkt); present in avcodec.h/ avcodec.a generating bad_access.

It was working fine with older version of static libraries but when i updated it to give my app support for arm64, its crashing with bad_access.

You can download a binary for FFmpeg 2.5.3 release at https://downloads.sourceforge.net/project/ffmpeg-ios/ffmpeg-ios-master.tar.bz2

Can i download this drag and drop the file and use ? I am totally new to this.
Or is it mandatory for me to run the scripts and generate the files.?

And things look different for ios8 and xcode 6.1 , a possbile script update?

Hello,
The above command seems to do what I need (trim a remote video file and save the results locally).
I need to do this on my iPhone but I could not use the library. The documentation is very obscure.

Can anyone help me?
Thanks

Sorry but i always get that error : build-ffmpeg.sh: line 92: cd: /Users/MyMac/build/built/armv7/lib: No such file or directory

If I also want to have the library for armv7s, is that I just need to edit ARCHS="arm64 armv7 x86_64 i386" to be ARCHS="arm64 armv7 armv7s x86_64 i386" in file build-ffmpeg.sh.

This might sound like a newbie question, but I am trying to compile ffmpeg with mp3 support. From what I have searched, I have to use libmp3lame.

• So I downloaded lame-3.99.5.tar, extracted it, ran ./configure, make, make install.
• I then editted the build-ffmpeg.sh, adding "--enable-libmp3lame" to the configure flags.
• running "./build-ffmpeg.sh" gives me an error libmp3lame >= 3.98.3 not found.

I clearly am missing a step. Am I suppose to copy files over to somewhere specific for it to look for? I would really appreciate some help.

When linking an app with the results of this build script for the simulator, it fails with the following error:

ld: illegal text-relocoation (direct reference) to (global,weak) _ff_h264_cabac_tables in ...(cabac.o) from _ff_h264_decode_mb_cabac in ...(h264_cabac.o) for architecture i386

Any thoughts on adding tvOS support?

When uncomment the #X264=pwd/fat-x264 I get: ERROR: libx264 not found
I did put the libx264.a under the fat-x264

any idea?

I want to play MMS address , Anyone help me to config <CONFIGURE_FLAGS="?......"> best, config something this <build-ffmpeg.sh> file.
Paly address like as blew:
mmst://live.cri.cn/oldies.wsx ;
mmsh://live.cri.cn/hyhq.wsx
mms://live.fm95.net/fm95;
rtsp://www.fmtz.net/fmtz;

I have write a demo for testing. this is demo : https://github.com/JobsWang/ADTSMedioFMPlayer

If I link against libraries compiled with this script I get a "moov atom not found" error thrown whenever I try to call avformat_open_input on a mov or mp4 file generated by an iphone. When I simply link against dylibs homebrew generates for ffmpeg, it works just fine. Any ideas?

After i build it,and finally it shows "Done",so i think it built successfully.
Then i import it to a new xcode project and build.
it reports libavutil/samplefmt.h not found,not only this one,all the "liba**/**.h"format #include have same error.

Dear,

When executing the script I receive the following output :

sh build-ffmpeg.sh 
    building arm64...
    Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
    Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
    xcrun -sdk iphoneos clang is unable to create an executable file.
    C compiler test failed.

The script is a fresh checkout, I'm trying ffmpeg version 2.7.2 & I've set the deployment target in the script to 7.0.

I've never done something like this before, so if you require additional logs/information I'll be happy too, if you point me to where I should get them from as well :)

Thanks in advance.

Hi

I found that the build does not have any of the muxers for example mpegts in the build. Is this by accident or by design. I tried building it using your shell script by adding configuration option --enable_muxers but no change. How do I get muxers into the build?

i download x264 source and rename to x264 in the directory .

run the command as : ./build-x264.sh
but fail

I am trying to build iFrameExtractor and it instructs the user to first build ffmpeg and use the resultant libraries in its project. I used your build script and although it built most of the libraries, it is missing libpostproc.a. How do I go about building that?

I followed the steps and built ffmpeg for armv7 and arm64.

How do you include FFmpeg in your project ?

Any use case example would be great.

Thanks!

Hello,
I am getting the https protocol not found message when I try to play a file from Dropbox. The streaming URL's from Dropbox starts with "https://" so I can't play the files. How can recompile the Framework with openssl or gnutls enabled?
Best regards,

when run build-x264.the lib dir is "fat-x264"
but in build-ffmpeg.sh,you wrote "fat_x264". must be a minor mistake.

I'm getting many warnings like : "ld: warning: URGENT: building for tvOS simulator, but linking in object file (/lib/libavutil.a(log.o)) built for iOS. Note: This will be an error in the future".

But it runs on both simulator and real device despite of these warnings.
How can i build without these warnings?

I need compile old version such as 0.8.7.
How can I modify the script?
Thank you.

Hi mate,

Would you mind to teach me how can I use ffmpeg with Cordova on iOS and Android?
I am trying to build an app with cordova that can use ffmpeg to transcode videos.

Many thanks

I was looking around to find the reason for the warning while running with the compiled FFmpeg:
"No accelerated colorspace conversion found from yuv420p to rgb24"
and found it's related to the reason of not usging the GPU.

did the following with no difference:

1. compiled the FFmpeg with x264
2. added to the configure flags: --enable-neon

this warning become when calling:
sws_getContext with PIX_FMT_RGB24 where the source is YUV420P

I need to include libz.dylib in order to get my project succesfully compiled.

if i removed the "--disable-asm" option, it shows "make: extras/gas-preprocessor.pl: No such file or directory" , please support neon。thx

i can compile i386, but when build arm64,armv7.i have such errors
libavcodec/aarch64/fft_neon.S:380:21: error: invalid immediate expression

i have installed yasm in /usr/local/bin/yasm
downloaded latest gas-preprocessor.pl
ffmpegc2.3.1 xcode5.1.1
what is wrong ? plz help me.

'libavutil.a(dict.o)' does not contain bitcode.
You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64

hi, thanks for your script, it's great helpful. Now i want to compile ffmpeg with x264 for iOS, what command should I write to use this script? Actually I want to use the 'preset' argument of ffmpeg but there is a hint "no such argument". I google that it needs the x264. So I want to compile the ffmpeg with x264. Thank you very much.

As the title says.

Hi kewlbear,
Could you help me to resolve my problem?

If i only build ffmpeg without x264lib, it work well.
But when i try to clone libx264 to local, build x264 by your "build-x264.sh". After that run "build-ffmpeg.sh". It's successful.

But when i import to Xcode project. That IDE give me error

I've tryed on real device, but still have same error.

Please help me.

Thanks and sorry for my bad english.

Thanks for the binary, but you forgot to add the config.h header. It should be in the root of the "include" folder.

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.
