• convert ogv to webm using ffmpeg and point ffmpeg to new installed version

  9 juin 2015, par Aisha

  I was facing problem in converting files from one format to another, so I put the question on stackoverflow, some people suggested me to recompile ffmpeg my ffmpeg version was 0.10.0 so they suggest me to install new one with full codecs from this link

  https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

  I followed the steps and installed new version but i didnot uninstall my old one and its still giving me error when i am converting video from ogv to webm

   /root/bin$ ffmpeg -i hello.ogv -acodec libvorbis -ac 2 -ab 96k -ar   44100 hello.webm

• Error in compiling x264 on ARM 64-bit platform

  2 septembre 2021, par yanzhang.guo

  The same x264 source code I compiled on Debian 10 (Buster) system has no problem, but I can't compile it on an ARM 64-bit platform. Why ?

  


  Maybe there is something wrong with the Makefile, but I don't know where it is.

  


  


  1. Configure

     


     ./configure --disable-asm --enable-shared  --host=aarch64-linux

platform:      AARCH64
byte order:    little-endian
system:        LINUX
cli:           yes

interlaced:    yes
avs:           avxsynth
lavf:          no
ffms:          no
mp4:           no
gpl:           yes
thread:        posix
opencl:        yes
filters:       crop select_every
lto:           no

gprof:         no
strip:         no

• ffmpeg build fails with gcc error even with gcc installed (C compiler test failed)

  15 mars 2023, par Martin

  I am on macos 11.2.3, trying to build ffmpeg in my terminal. When I run my script sh buildffmpeg.sh which is below :

  


  #!/bin/bash

# If you get error `c compiler failed` run `sudo apt install libglfw3-dev libglew-dev`
# apt-get install build-essential
# apt-get build-dep ffmpeg
# when running this on mac, you need to install some libraries such as 'brew install opus'

  It fails with this error :

  


  > sh buildffmpeg.sh

Extracting...
Building...
gcc is unable to create an executable file.
C compiler test failed.

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
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.


  


  I have been trying to solve this error, and have installed gcc with brew, if i run gcc -v I can see my installed gcc version :

  


  $ gcc -v
Using built-in specs.

  So if gcc is installed correctly (i think) why is it failing with a gcc error when I build ffmpeg ?
