ffmpeg chroot jail from Gentoo linux (ffmpeg 4.1 with gcc 8.2)

Here we build a Gentoo ssh chroot jail. You may need this because

  • you want the bleeding edge versions of the video libraries like x264, x265, ffmpeg the latest version and so on.
  • latest version of GNU C library and the compiler GNU GCC (version 8.2) at the moment
  • use all the optimizations for compiling the ffmpeg and the libraries for you current processor. Use “-march=native”
  • you want just to be able to update your system and not to break your carefully compiled latest version ffmpeg
  • experiment with GCC compile flags
  • update and test in another directory by just copying the old chroot jail directory
  • no need of any additional software on the host (like virtualization lxc, docker, qemu, etc)
  • or you might want a 32bit version (why? really? but it is possible…)

Of course, you can use for the base any Linux system, but it is easy with Gentoo – the latest versions of almost all important libraries and a packet system, which builds everything for you after a little bit of first tuning…

So here is how to do it:

Use Intel QuickSync with ffmpeg to have hardware accelerated video decoding and encoding – CentOS 7.4.1708

This howto shows how you can use ffmpeg to hardware accelerate the video decoding and encoding if you have the proper Intel processor. Some of the Intel processors have GPU unit in them, which can be used to decode and encode video streams and it is pretty fast! High end Intel CPU could encode around 20 h264 (using faster preset) video streams on a single processor mini server as SUPERMICRO system using X11SSV-M4F.
Here are the steps how to enable the hardware options and what and how to install the software to hardware encode a video stream successful under linux – CentOS 7 distro.

For the first four steps just follow the howto “Install Intel Media Studio SDK and GPU driver from Intel Media Server Studio 2018 R1 – CentOS 7 (7.4.1708)” Here we include only the headers of the steps, because they are important part of this howto.
Installing Media Server Studio your system will get validated stack of software by Intel to build application against Media SDK interface:

  • libmfx.a dispatcher – the API for your application
  • libmfxhw64.so hardware implementation
  • related libraries (including OpenCL)
  • specific versions for libva and libdrm
  • user mode driver
  • modified i915 graphics driver module
  • kernel patches

Here are the steps:

STEP 1) Enable internal graphics in your system.

STEP 2) Install the right CentOS 7 – 7.4.1708

STEP 3) Download Intel Media Server Studio 2018 R1

STEP 4) Install Intel Media Studio SDK from Intel Media Server Studio 2018 R1

“Install Intel Media Studio SDK and GPU driver from Intel Media Server Studio 2018 R1 – CentOS 7 (7.4.1708)”

STEP 5) Tune pkgconfig libmfx (Intel library, installed with the Media Server Studio)

Create a file:

/usr/lib64/pkgconfig/libmfx.pc

with the following content:

prefix=/opt/intel/mediasdk
exec_prefix=${prefix}
libdir=${prefix}/lib/lin_x64
includedir=${prefix}/include
 
Name: libmfx
Description: Intel Media SDK
Version: 16.8
Libs: -L${libdir} -lmfx -lva -lstdc++ -ldl -lva-drm -ldrm
Cflags: -I${includedir} -I/usr/include/libdrm

STEP 6) Move the Media SDK include files in a mfx sub-directory

This is required because ffmpeg expect these files to be in a sub-directory

[root@srv ~]# mkdir /opt/intel/mediasdk/include/mfx
[root@srv ~]# cp /opt/intel/mediasdk/include/*.h /opt/intel/mediasdk/include/mfx/

STEP 7) Install yasm – a dependency for the ffmpeg software.

[root@srv ~]# wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
[root@srv ~]# tar xzf yasm-1.3.0.tar.gz

STEP 8) Download ffmpeg version 2.8.X and compile it

it is important to use this branch 2.8.X because we’ve tested with the others 3.2.X, 3.3.X, 3.4.X and there were errors and we unable to use the the GPU unit to accelerate our video decoding and encoding. Here is the different ffmpeg release https://ffmpeg.org/download.html#releases or you can use the github to download https://github.com/FFmpeg/FFmpeg/releases

And now you have a ffmpeg installation build against Intel API libmfx dispatcher, which could benefit from the hardware acceleration in decoding and encoding video streams. Thus using a Intel QuickSync technology.

You can see ffmpeg is using VA-API and /opt/intel/mediasdk/lib64/iHD_drv_video.so for video acceleration encoding.

* Live stream decoding and encoding with hardware acceleration and outputting multiple output

The input stream is from a multicast source and the output is a wowza server
