Compiling ffmpeg with NVIDIA GPU Hardware Acceleration on Ubuntu 20.04LTS

Please note that the following commands were executed on a system that already had CUDA support so we might be missing a step or two to enable NVIDIA CUDA support.

Install necessary packages

sudo apt-get install build-essential yasm cmake libtool libc6 libc6-dev unzip wget libnuma1 libnuma-dev nvidia-cuda-toolkit;

Clone and install ffnvcodec

git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git;
cd nv-codec-headers;
sudo make install;
cd -;

Clone and compile FFmpeg’s public GIT repository with NVIDIA GPU hardware acceleration

git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg/;
cd ffmpeg;
./configure --enable-nonfree --enable-cuda-nvcc --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 --disable-static --enable-shared;
make -j 8;
sudo make install;

SUCCESS!

After performing the above steps, we were able to process media using ffmpeg without stressing our CPU! The workload was transferred to the GPU!

413 Request Entity Too Large

We tried to upload a large file to a WordPress site and got the following error:

413 Request Entity Too Large

The WordPress installation was behind an Nginx reverse proxy.

To fix this, we added the following line in the /etc/nginx/nginx.conf configuration file inside the http section/context:

client_max_body_size 64M;
http {
    ...

    client_max_body_size 64M;

    ...
}

Syntax: client_max_body_size size;
When client_max_body_size is not set, it defaults to the value of one megabyte;
It can be set to any of the three following contexts: http, server, location
client_max_body_size sets the maximum allowed size of the client request body. If the size in a request exceeds the configured value, the 413 (Request Entity Too Large) error is returned to the client. Please be aware that browsers cannot correctly display this error. Setting size to 0 disables checking of client request body size.

Source: https://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size

After making the change to the configuration file, we restarted Nginx to apply the changes.
