• Location of the amd64 compiler in Visual Studio 2022 | Compiling FFmpeg with NVENC

  6 juin 2022, par Gal Grünfeld

  I'm trying to follow Nvidia's guide to compile FFmpeg with nvenc support on Windows and it has a stage to export the path of Visual Studio's 2013 SP2 amd64 compiler to the global path variable of the compilation dev environment :

  


  


  export PATH="/c/Program Files (x86)/Microsoft Visual Studio 12.0/VC/BIN/amd64/" :$PATH

  


  


  They say earlier in the guide that for different versions of Visual Studio different path might be required. I'm trying to use Visual Studio 2022 Community, but don't know where its amd64 compiler directory is.
I also don't know what that VC stands for ("Visual C", maybe, whatever that "Visual" might mean ?).

  


  I found in the installation directory of Visual Studio 2022 a few directories named amd64 but none of them were under one with VC or something similar in its name.
The one I think is the most likely candidate to be the updated compiler is at /MSBuild\Current\Bin\amd64.

  


  If anyone knows, please tell me if if this is the right path, and if not, what is the right path.

  


  Microsoft does offer a version of Visual Studio 2013 Update 2, though (I assume they changed their naming scheme from "service packs" to "updates, which would make it the same software), but it doesn't offer a 64-bit version of it, and I want to compile a 64-bit software - so I assume it doesn't come with one. Please do correct me if I'm wrong, it'd save me needing to use a version of Visual Studio that is different than the one in the guide.

• How to Install FFMpeg on centos 6 in 2022 ?

  17 août 2022, par Ruben Fernandes

  a client of mine asked to add videos to their website, i decided to install FFMpeg on their server so whenever they upload a video, the service automatically generates the first frame for the preview and encodes them in webm.

  


  Sadly it seems to be impossible to install without having to compile it myself (which i don't really want to do as i have never done it before and don't want to risk breaking something in their server),

  


  The server is running cento6 but EVERY repository that provides the centos6 version of FFMpeg seem to use dependencies from dead hosts (they are offline and unreachable), every solution i find ends up with the same error like "Couldn't resolve host 'apt.sw.be'"

  


  I've changed yam repositories, installed apt-get to try with that instead of yam, disabled and enable repos like nux that seem to be very outdated, even followed posts that were published/updated recently like this but they all keep ending up with the the same "Couldn't resolve host..." when installing decencies.

  


  Is there any live and updated repo that provides a way to install FFMpeg for centos6 with yum or apt-get in 2022 ?

  


  Thanks

  


  EDIT
Following Romeo's tip about downloading the binaries, i managed to install it but in my case i needed a older 32 bit version to make it work (else i'd get Kernel too old) :

  


  $ wget https://www.johnvansickle.com/ffmpeg/old-releases/ffmpeg-4.0.3-32bit-static.tar.xz
$ tar xvf ffmpeg-4.0.3-32bit-static.tar.xz
$ sudo mv ffmpeg-4.0.3-32bit-static/ffmpeg ffmpeg-4.0.3-32bit-static/ffprobe /usr/local/bin/
