Question

I m 试图将ffmpeg作为独立的双手(因为我想在AWS lambda中使用)

在Im编辑的服务器上,我可以做一些事情,但是,如果我复制本并从另一个服务器操作,我会:

/ffmpeg:在装上共享图书馆时的错误:libvdpau.so.1:不能开立共同的物体档案: 无此类档案或目录。

So it sounds like something didn t made it into the binary. From what I ve read, I ve to compile ffmpeg with the flags --disable-shared and --enable-static, which I ve done:

PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure 
  --prefix="$HOME/ffmpeg_build" 
  --pkg-config-flags="--static" 
  --extra-cflags="-I$HOME/ffmpeg_build/include" 
  --extra-ldflags="-L$HOME/ffmpeg_build/lib" 
  --bindir="$HOME/bin" 
  --disable-shared 
  --enable-static 
  --enable-gpl 
  --enable-libass 
  --enable-libfreetype 
  --enable-libmp3lame 
  --enable-libvpx 
  --enable-libx264
PATH="$HOME/bin:$PATH" make
make install
make distclean
hash -r

是否有人失踪?

Answer 1

--enable-static and --disable-shared only affect libav* binaries. It doesn t prevent linker to use necessary shared object files.

纯粹的静态平衡,就会是trick和肉。你们必须建设你们所需要的每一个静态平衡,然后努力在大战中增加新的ld。

另一种选择是将这些校准/参考/组合整理成大的工具。其中一部分列于以下网站:。包裹共用图书馆进入代号

尽管我成功地用双双手汇编了所有材料,但我还是能够把依赖物上载到AWS lambda:

copy all dependencies in a folder

我写了一幅大写的文字来做。文字依据<代码>lld,列出属性。

#!/usr/bin/env python
import subprocess
import os
from shutil import copyfile

def copyLibraries(bin, destination):
  if not os。path。exists(destination):
    os。makedirs(destination)

  output = subprocess。Popen(["ldd", bin], stdout=subprocess。PIPE)。communicate()[0]
  for l in output。split( 
 ):
    if len(l。split("=> ")) > 1:
      lib_location = l。split("=> ")[1]。split(" ")[0]。strip()
      if lib_location != "":
        real_location = os。path。realpath(lib_location)

        lib_name = real_location。split( / )[-1]

        copyfile(real_location, destination + lib_name)

        if os。path。islink(lib_location):
          link_name = lib_location。split( / )[-1]
          if link_name != lib_name:
            os。symlink(real_location, destination + link_name)

copyLibraries("/home/ubuntu/bin/ffmpeg", "/home/ubuntu/libs/")

AWS lambda

include the ffmpeg binary as well as the libs folder in the lambda zipped code。
in the lambda code, include the corresponding paths。 In node。js this can be done as:

。

process。env[ PATH ] = process。env[ PATH ] +
   :  +    process。env[ LAMBDA_TASK_ROOT ] +
   :  + process。env[ LAMBDA_TASK_ROOT ] +  /bin  +
   :  + process。env[ LAMBDA_TASK_ROOT ] +  /lib ;

Answer 3

添加<条码>-extra-ldexeflags=“-static”,以获得独立的条码。

Answer 4

如果您在开发机上有Nix,你可以使用以下一种指令:

nix-build  <nixpkgs>  -A pkgsStatic.ffmpeg-full
# this might take a while, since you re compiling **everything** required by ffmpeg
# once this is done, check that the file is what you need
file ./result/bin/ffmpeg

如果你处于ARM64-030,需要静态AMD64,则情况有所不同。 Denis Gosnell s blog for more details.
