Installing Ffmpeg Source Code on youyeetoo X1

Installing Ffmpeg Source Code on youyeetoo X1

Preface

Hello, everyone. Today, I have some free time to review a development board. This board is highly capable and comes with a rich set of peripheral resources. I'll show you the external interfaces and features of this board.

Above is a visual overview for your reference, and now let's provide a formal introduction to this board:

The youyeetoo X1 is a single-board computer (SBC) based on the x86 architecture, introduced by Shenzhen Windfirewheel Technology. It is capable of running full-featured Windows and Linux operating systems and boasts low cost and high performance, thanks to its 11th-generation Intel CPU N5105. The board primarily targets the AIOT (AI of Things) and automation control markets. Despite its small form factor, measuring only 115 x 75mm, it offers a rich set of interfaces, including 3 UART serial ports, 2 HDMI ports, 6 USB ports, 1 I2C interface, 1 SPI interface, and 5 GPIO pins, which are commonly used in AIOT and IoT applications. Additionally, it supports a 7-inch MIPI touchscreen display.

To install ffmpeg from source on youyeetoo X1:

For basic tutorials regarding the board, you can refer to the wiki tutorials:

Here, I will primarily focus on compiling and installing FFmpeg from source on Ubuntu. The process is similar to installing Linux in a virtual machine, similar to what we do when learning Linux. The wiki provides a tutorial with steps, so I won't reinvent the wheel:

Let's start preparing to install FFmpeg:

1. Compile AAC:

AAC download link:

Begin compiling:

• 1、./configure --prefix=/usr/local/ffmpeg/ --enable-shared
• 2、make -j8 && make install

Here I have placed the compiled files in /usr/local/ffmpeg/ and only compiled the shared libraries. You can follow the two steps above for the operation.

The dynamically compiled libraries are located in /usr/local/ffmpeg/lib, and the header files are in /usr/local/include.

2. Compile x264:

Download the x264 source code from the following link:

wget http://ftp.videolan.org/pub/videolan/x264/snapshots/x264-snapshot-20191024-2245-stable.tar.bz2

Let's start the compilation:

1、./configure --prefix=/usr/local/ffmpeg --enable-static --enable-pic

2、 make -j8 && make install

Here, we place the compiled files in the directory /usr/local/ffmpeg, and we are compiling static libraries:

Note: If you encounter an error about an outdated NASM version during your initial installation, you will need to download NASM source code and compile it again:

Here are the installation steps for NASM. First, download NASM using the following link:

wget https://www.nasm.us/pub/nasm/releasebuilds/2.14.02/nasm-2.14.02.tar.bz2

Compilation steps:

1、./configure

2、make -j8 && make install

Okay, this operation is relatively simple. Just follow these instructions. If you encounter errors when installing x264 for the first time, reinstalling nasm as described above can resolve the issue. Now, let's proceed with the x264 installation:

The generated header files and static libraries should also be placed in the /usr/local/ffmpeg directory:

3. Compile x265

x265 download link: wget http://ftp.videolan.org/pub/videolan/x265/x265_3.2.tar.gz

Compilation steps:

1、cd x265_3.2/build/linux/

2、./make-Makefiles.bash

3、 make -j8 && make install

You can see that the libraries and header files compiled for x265 are respectively placed in the /usr/local/lib and /usr/local/include directories.

Compiling and Installing FFmpeg from Source Code:

Here we are using the source code from Gitte, as downloading from GitHub can be a bit slow.

git clone https://gitee.com/mirrors/ffmpeg/

We download it and switch to the 5.1 branch:

git checkout -b remotes/origin/release/5.1

And then start compiling:

1、./configure --prefix=/usr/local/ffmpeg --enable-gpl --enable-shared --enable-version3 --enable-nonfree --enable-pthreads --enable-libx264 --enable-libx265 --enable-libfdk-aac

2、make -j8 && make install

We found that libfdk_aac couldn't be located. To resolve this, we need to set the environment variables: vi ~/.bashrc

Then, exit the terminal and run source ~/.bashrc to make it take effect. The reason for this is mainly to locate fdk-aac using the fdk-aac.pc file within this context.

Now, when you run the previous configuration again, it should resolve this issue. If you encounter similar problems in the future, you can refer to this approach to resolve them. The key is to locate the .pc file corresponding to what you have compiled.

Continuing from here, let's proceed with the compilation. This process may take a while. I'll only show you the "make install" part:

Finally, you can find the generated libraries in the /usr/local/ffmpeg/lib directory.

Executable programs and header files:

Configure the environment variables here as well:

At this point, you can check the version of FFmpeg from any terminal by running the following command:

The last:

This concludes the brief evaluation of this board. Unfortunately, I don't have an HDMI cable to test multiple displays, but you've seen the board's capabilities and how to install FFmpeg for multimedia tasks. If you have any further questions or need assistance with anything else, feel free to ask.
