Preface
Renesas RZ/G2L is a high-performance, ultra-efficient chip for the industrial field. It has rich multimedia functions and abundant display, camera, and audio interface resources to meet the needs of human-computer interaction and image acquisition. It is suitable for industrial HMI, medical, industrial automation, power, display and control terminals and other scenarios.
This article takes the construction of ffmpeg development environment and performance testing as an example to experience the application of this development board in multimedia and other fields.
Prepare
The following development is based on the WIN11+WSL2 environment. You need to install the necessary tool chains such as aarch64-linux-gnu-, etc., which will not be repeated here.
Download the code
Cross-compiling
./configure --cross-prefix=aarch64-linux-gnu- --enable-cross-compile --target-os=linux --cc=aarch64-linux-gnu-gcc --arch=arm64 --prefix=/ home/lhj/opt/ffmpeg/board --enable-ffmpeg --disable-armv5te --disable-armv6 --disable-armv6t2
(Note that you need to create the /home/lhj/opt/ffmpeg/board folder first)
WARNING: aarch64-linux-gnu-pkg-config not found, library detection may fail.

Test results comparison
It can be seen that the development board has no problem processing 720p and 40 frames.
The gap is more than 10 times that of a PC, but compared to the comprehensive environment of desktop-level DDR, SSD and CPU, the performance of the development board is already very good.
