Setup of Custom FFMPEG with Acceleration of GPU

The Video Codec SDK includes a complete set of high-performance tools, samples and documentation for hardware accelerated video encode and decode on Windows and Linux.

The SDK consists of two hardware acceleration interfaces:

  • NVENCODE API for video encode acceleration
  • NVDECODE API for video decode acceleration (formerly called NVCUVID API)

NVIDIA GPUs contain one or more hardware-based decoder and encoder(s) (separate from the CUDA cores) which provides fully-accelerated hardware-based video decoding and encoding for several popular codecs. With decoding/encoding offloaded, the graphics engine and the CPU are free for other operations.

GPU hardware accelerator engine for video decoding (referred to as NVDEC) supports faster than real-time decoding which makes it suitable to be used for transcoding applications, in addition to video playback applications.

The following code will remove ffmpeg and related packages:

sudo apt-get -y remove ffmpeg x264 libx264-dev
Get NVENC SDK from the NVIDIA developer’s site for cuda enabled ffmpeg libav https://developer.nvidia.com/nvidia-video-codec-sdk
 

Follow the steps provided in following document: FFMPEG-with-NVIDIA-Acceleration-on-Ubuntu_UG_v01.pdf

Install the build infrastructure packages

sudo apt-get install build-essential git yasm nasm unzip wget sysstat
 
NVENC SDK

Copy the NVENC SDK that you downloaded from above side to ~/Development

mkdir Development 
cd Development 
cp Video_Codec_SDK_8.0.14.zip Development/ (or copy paste though GUI) 
unzip Video_Codec_SDK_8.0.14.zip

Copy the NVENC headers to /usr/local/include to make it easier later

sudo cp Video_Codec_SDK_8.0.14/Samples/common/inc/*.h /usr/local/include

CUDA UTILITY

Download and install a light-weight library to communicate with the CUDA display driver.

~/Development/ $ wget http://developer.download.nvidia.com/compute/redist/ffmpeg/1511-patch/cudautils.zip

Copy the CUDA utility to ~/Development/.

~/Development/ $ unzip cudautils.zip 
~/Development/cudautils/ $ cd cudautils

Build the CUDA utility.

~/Development/cudautils/ $ make 
~/Development/cudautils/ $ cd .. 
~/Development/ $

OPEN SOURCE LIBRARIES

Get x264

~/Development $ git clone git://git.videolan.org/x264.git 
~/Development $ cd x264

Configure x264

~/Development/x264 $ ./configure \ 
--disable-cli \ 
--enable-static \ 
--enable-shared \ 
--enable-strip

Build x264.

~/Development/x264 $ make -j 4

Install x264.

~/Development/x264 $ sudo make install 
~/Development/x264 $ sudo ldconfig 
~/Development/x264 $ cd .. 
~/Development/ $

BUILD IT ALL TOGETHER

Get FFmpeg.

~/Development/ $ git clone git://source.ffmpeg.org/ffmpeg.git

Download the NVIDIA acceleration.

~/Development/ $ wget http://developer.download.nvidia.com/compute/redist/ffmpeg/1511-patch/ffmpeg_NVIDIA_gpu_acceleration.patch 
~/Development/ $ cd ffmpeg

Apply the NVIDIA acceleration patch. Note that this patch was created against the
git master commit:
commit b83c849e8797fbb972ebd7f2919e0f085061f37f

~/Development/ffmpeg $ git reset --hard b83c849e8797fbb972ebd7f2919e0f085061f37f 
~/Development/ffmpeg $ git apply ../ffmpeg_NVIDIA_gpu_acceleration.patch

Configure FFmpeg with NVENC, NVRESIZE and x264 support.

~/Development/ffmpeg $ cd .. 
~/Development/ $ mkdir ffmpeg_build 
~/Development/ $ cd ffmpeg_build 
~/Development/ffmpeg_build $ ../ffmpeg/configure --enable-nonfree \ 
--enable-nvenc \ 
--enable-nvresize \ 
--extra-cflags=-I../cudautils \ 
--extra-ldflags=-L../cudautils \ 
--enable-gpl \ 
--enable-libx264

Build FFmpeg.

~/Development/ffmpeg_build $ make -j 4

Check that FFmpeg works. If NVENC and libx264 built properly you should get 
them in this list of encoders. We can filter the list down to h.264 encoders with “grep
264”.

~/Development/ffmpeg_build $ ./ffmpeg -encoders | grep 264 
.................................. 
.....Somethings here.............. 
V..... libx264 libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (codec h264) 
V..... libx264rgb libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 RGB (codec h264) 
V..... nvenc NVIDIA NVENC h264 encoder (codec h264) 
V..... nvenc_h264 NVIDIA NVENC h264 encoder (codec h264)

Check that FFmpeg has the NVRESIZE video filter. We can filter the list down with
“grep nvresize”.

~/Development/ffmpeg_build $ ./ffmpeg -filters | grep nvresize 
.................................. 
.....Somethings here.............. 
nvresize   V->N GPU accelerated video resizer.

Install FFmpeg.

~/Development/ffmpeg_build $ sudo make install 
~/Development/ffmpeg_build $ sudo ldconfig 
~/Development/ffmpeg_build $ cd .. 
~/Development/ $ cd .. ~/ $

Done!!!
