avbuild's Issues

Cross build using mingw fails on both MSYS2 and Ubuntu 16.04

Having successfully built FFmpeg 2.1.5 on Ubuntu 16.04, I installed mingw (sudo apt-get install mingw-w64) and issued the build command given in the wiki (./avbuild.sh mingw x86_64) and the script fails quickly with the following output:

If I instead use ./avbuild.sh mingw x86_64 it fails the same way as with linux above.

Attempted this in Windows using VS2015 as well:

bash
export FFSRC=ffmpeg-src
./avbuild.sh

...results in a linux build.

./avbuild.sh vc

...fails with 'c/configure: c99wrap: not found'

Is there any help you can give to get me on the way to create a windows 64 bit build of my required version of FFmpeg?

这些版本是把那些第三方库都包含进去了吗

比如 libfdk-aac

Add x86_64 builds for Android

Currently there are no x86_64 builds for android clang. Do you plan to also add support for this?

Sets NDK_ROOT automatically

Although I have specified NDK_ROOT before your script "config-android.sh" overwrites my value. I had to remove the statement to use my own NDK_ROOT path.

MacOS builds successfully but fails at runtime with Symbol not found: _av_get_dict

I'm using the libraries with QtAV on MacOS SDK 10.12. Building against FFmpeg 4.1 is successful but fails during execution with symbol not found. Another user with similar setup wang-bin/QtAV#1161 has the same problem.

The issue seems to be resolved by removing -flat_namespace EXTRA_LDFLAGS inside avbuild.sh setup_macos_env(). This was introduced in 24b7098.

Do you happen to remember the original purpose of the flag? From Apple's documentation, it "Changes from a two-level to a single-level (flat) namespace." Not sure how its removal will affect QtAV, if at all.

Errors on glibc when trying to link with FFmpeg builds for Linux

Using the builds ffmpeg-4.2-linux-gcc-lite.tar.xz and ffmpeg-4.1-linux-gcc-lite.tar.xz for Linux in sourceforge gives me this error related to glibc:

libavcodec.so: undefined reference to `powf@GLIBC_2.27'
libavformat.so: undefined reference to `glob64@GLIBC_2.27'
libavcodec.so: undefined reference to `log2f@GLIBC_2.27'
libavcodec.so: undefined reference to `expf@GLIBC_2.27'
libavcodec.so: undefined reference to `exp2f@GLIBC_2.27'
libavcodec.so: undefined reference to `logf@GLIBC_2.27'

Where as using ffmpeg-4.0.3-linux-gcc-lite.tar.xz compiles normally.
It seems that the newer versions are built against glibc 2.27, while I have glibc 2.23 on my Ubuntu 16.04. Is there any solution to this?

2. No problems when compiling arm64-clang, x86-clang, x86_64-clang against Android r19.
 

Android: made clean build of full version, encoder doesn't work

As per subject. I made a build of ffmpeg for Android (full version) and call to:
avcodec_find_encoder(AV_CODEC_ID_H264)
returns 0.

Is there whole ffmpeg executable file without so files ?

Is there whole ffmpeg executable file without so files ? it is around 20M.
BTW, how to use the small ffmpeg excecubale in downloaded package? it needs .so lib files ?

请问能将libass静态链接到ffmpeg中吗？

您编译的ffmpeg没有链接libass，因此很多外挂字幕都没法正常显示，ffmpeg官方的做法是将libass静态链接到ffmpeg中，因此也不需要额外的dll

Unable to create mkv containers on Android using lite version

When using the built FFmpeg 4.2 Lite on Windows and Linux I can create mkv containers using avformat_alloc_output_context2. But using the built FFmpeg 4.2 Lite (armeabi-v7a) on Android, trying to create mkv containers for the same video gives me error:

[FFmpeg:NULL] Unable to find a suitable output format for '/data/data/Sample/files/1.mkv'

But using mp4 is fine on Android. Is this feature for mkv turned off for Android?

Recent sysroot build failure

Thanks for this great build tool!
I think your recent commit 5fd5204 broke my build. It will complain about the sysroot, which is also changed in the commit. Could you tell me whether I am using your tool wrong?

我想使用C#调用FFmpeg，但是不知道FFmpeg的调用约定是什么？

备注：我看过FFmpeg的头文件，没有见到调用约定的关键字和导入导出C函数的关键字。

error build ffmpeg for android ndk r16

Hi,
it is impossible to build ffmpeg for android with ndk r16.
the error is the following:
fatal error: jni.h: No such file or directory
#include <jni.h>

with r15c it is possible.
Thanks

想问下这个脚本适合ndk r19吗

遇到报错
/bin/sh: error while loading shared libraries: libc.so.6: cannot open shared object file: Error 24
应该是找不到库，我的环境就配置了俩：

export FFSRC=../ffmpeg-4.1
export ANDROID_NDK=../android-ndk-r19
./avbuild.sh android "armv7"

Android builds >= 5.0 require PIE support

Invocation of FFMPEG we get "only position independent executables (PIE) are supported."

Hi, do you plan to support WSL on Windows 10 as host

使用vcpkg编译的方式，如何编译intel qsv硬编？

要启用GuardCF，链接器也需要传一个参数

如果想要启用GuardCF这个特性，不仅需要给编译器传/guard:cf这个参数，链接器也需要传一个相同的参数/guard:cf，链接器缺少这个参数的话这个特性其实是没有启用的。

从下面的两幅图片也可以看出，图一是MDK自带的ffmpeg，就是用这个仓库的脚本编译的，我看了您写的脚本，发现您已经传了-guard:cf或-cfguard参数，看得出来您是想启用这个特性的，但是您没有给链接器也传这个参数，所以实际上最终得到的文件是没有启用这个特性的。

而图二是我自己用clang-cl + lld-link编译的ANGLE，从图里能看到，特性里多了GuardCF这个关键词，这才是真正启用了，而您自己编译的不管是MDK还是ffmpeg，都没有这个关键词，也就是都没有真正启用这个特性。

No prebuilt package for Desktop VS2015 x86

Hi I found that no prebuilt version for Visual Studio 2015 and x86 is done.

How can I launch avbuild for that target? Do I need to launch from linux machine?

Android SSL problem

Hi and thanks for this project.
When I called https urls, I get SSL errors. How can I build ffmpeg for android with SSL support?

multiple architectures as script arguments

archs are separated by +. appends -compiler to switch compiler.

./avbuild.sh ios                       # use default archs: armv7+arm64+x86+x86_64
./avbuild.sh android                   # use default archs: gcc armv5+armv7+arm64+x86
./avbuild.sh android armv7+arm64-clang # use gcc armv7 and clang arm64

ios.sh can be removed.

building for Windows from macOS, Clang+LLD

Hello to you all, can someone give me some hints?

My macOS host build works fine. Now I am trying to make build for Windows and I am out of ideas how to proceed. I managed (hopefully successfully) integrate lld-link as I can see it in the log being used --ld="/Users/matousvencl/projects/llvm/build/bin/lld-link ".

I wonder what those two options do:

-DEFAULTLIB:msvcrt" 
--extra-libs="oldnames.lib"

as I can see there is error related to them in the log:

lld-link: error: could not open oldnames.lib: No such file or directory
lld-link: error: could not open msvcrt.lib: No such file or directory

Build for android

Hello,

What does these tools build ? a library or an executable ? Also does it use GPL parts of ffmpeg or only LGPL ?

I need to build FFMPEG for a commercial product on Android but the ones on the internet are built for android using GPL source code, and are not up to date (current one i use is 2.4 version)

Thanks in advance

FFmpeg changed the version.sh script to ffbuild sub dir

FFmpeg moved version.sh to ffbuild sub dir in version 4.1, the avbuild.sh script will not run correctly when excute under mac osx. To solve this, change the script to following will work:

cd $FFSRC
if [ -e `version.sh` ];
then
FFVERSION_FULL=`./ffbuild/version.sh`
FFMAJOR=`./ffbuild/version.sh |sed 's,[a-zA-Z]*\([0-9]*\)\..*,\1,'`
FFMINOR=`./ffbuild/version.sh |sed 's,[a-zA-Z]*[0-9]*\.\([0-9]*\).*,\1,'`
else
FFVERSION_FULL=`./version.sh`
FFMAJOR=`./version.sh |sed 's,[a-zA-Z]*\([0-9]*\)\..*,\1,'`
FFMINOR=`./version.sh |sed 's,[a-zA-Z]*[0-9]*\.\([0-9]*\).*,\1,'`

android gcc如何编译？

以下是输入的命令：
export FFSRC=D:/zzxs/codes/FFmpeg-master ./avbuild.sh android "armv7-gcc"

sh文件中添加：

build失败，如下：
configuration changes clang is unable to create an executable file. C compiler test failed. ...... ...... /d/zzxs/codes/FFmpeg-master/configure: line 984: clang: command not found C compiler test failed.

创建了文件夹：build_sdk-android-armv7-clang

请问armv7-gcc如何正确编译？

only add one line

--enable-ffplay \

and compile with command

./avbuild.sh macos10.14.4 "x86_64"

as a success result find no ffplay command

can't I build ffmpeg with ffplay for macos ?

dlopen failed: invalid ELF file android

Hi,
when I use the master prebuilt libraries I have the following error
dlopen failed: invalid ELF file /usr/arm64/libswscale.so.
I don't have this error with the 4.2 libraries.
I need the master because I have to compile for x86_64 for android and in 4.2 prebuilt zip there are not the x86_64 libs.
Thank you very much
Angelo

HTTPS support for Android build

Currently https is not supported in any of Android builds. Is it trivial to add support for https on android?

No OS X build option?

Trying to build QtAV with FFmpeg with libx264 enabled. But I can't seem to find option for OS X? Why? And how do I enable specific codecs?

Thank you!

Your script expects the path "android-ndk-r12b/toolchains/x86_64-linux-android-4.8". The NDK path is actually "android-ndk-r12b/toolchains/x86_64-4.8", so it does not find the compiler. For the arch "aarch64" it works since here the folder has your specified path in the NDK.

ffmpeg4.2 Android arm64-v8a 版本无法加载libswscale 报错：invalid ELF file

参考：https://stackoverflow.com/questions/60850313/invalid-elf-file
我遇到了和如上链接相同的错误：
我按照WIKI上Android的编译步骤，成功编译出了arm64-v8a 和 armeabi-v7a版本的 QtAV so库
其中 armeabi-v7a 能够正常加载并且运行一切正常
后来我需要把编译的目标 ABI 切换到 arm64-v8a 发现这个错误，起初怀疑是下载的so库有问题，后来重新下载了ffmpeg4.2的两个目前最新的版本：ffmpeg-4.2-android.tar.xz 和 ffmpeg-4.2-android-lite.tar.xz
报错都是和上边一样的，怀疑是libswscale这个库arm64编译出的文件或编译配置有问题？求助如何能够解决此问题。

build ffmpeg and after QtAV with clang

Hi, I want to know if it is possible to compile ffmpeg with your script avbuild.sh and after QtAV with clang for android.
In ndk r14 gcc is deprecated and it is impossible to compile ffmpeg with gcc.
Thank you very much

请求添加 filter: crop 的支持

裁剪视频是很常见的操作，但是目前 config-lite.sh 没有开启这一 filter，请添加一下。

pkg-config uses wrong prefix

Hi, thanks for the great build scripts.
I use avbuild to build ffmpeg for android. I want to use pkgconfig to find the libraries, however the pkgconfig files use /usr/local as the prefix instead of the actual path where the libraries are installed.
I can fix it by running the following command, but I would prefer it to be fixed upstream :-)
sed -i 's#/usr/local#/home/user/avbuild/sdk-android-armv7-clang#g' /home/user/avbuild/sdk-android-armv7-clang/lib/pkgconfig/*

windows-desktop的静态库不能用了

今年五六月份我曾经用过您编译的静态库，能完美使用，但最新的不行了。

最近您更新的静态库，突然就需要libmfx了，而且不链接这个库会报错，必须要链接它，但我明确记得以前是不用链接这个库的。

我使用的是您上传的libmfx，Qt是我自己编译的静态版，QtAV和自带的examples都能编译成功，但都无法正常运行，打开是能打开，但只要播放媒体文件就会立即崩溃。无法上传日志，因为来不及写入日志，程序就崩了，日志文件都是空的。我曾经试过英特尔官网的libmfx，也能正常编译，但同样会崩掉。

我感觉应该不是Qt配置的问题，我编译时用的都是默认的配置，opengl 是 dynamic，VC运行时是 -MD。而且编译其他程序都没问题，运行也都很正常。难道与VS版本有关？我用的是最新版的VS2017（目前是15.8.8），但VS2017已经更新好几次了，每次重新编译的程序都会崩掉，感觉跟VS版本也没多大关系。

CONFIG += static_ffmpeg 我加上了，而且看编译后的二进制文件大小，ffmpeg应该是链接进去了的，这个没什么问题，就是程序总是会崩掉。

能否提供LAVFilters的动态库

项目地址： https://github.com/Nevcairiel/LAVFilters ， LAVFilters 是一个基于 FFmpeg 的容器/音视频分离器，作者一直在维护但是并没有发布新的二进制文件，而已有的二进制文件使用的 ffmpeg 已经很旧了。

Android prebuilt包在6.0后无法使用

谷歌在Android 6.0也就是Api level 23之后改变了使用外部库的安全策略，所以使用23之后的SDK编译的话无法继续使用提供的prebuilt包
