About Us
Modelcam Technologies provides a wide variety of Services from ART to PART from Concept Design to Industrial Modeling and Analysis for final Manufacturing.
If you’ve ever tried to build video processing software for embedded Linux, you know the pain. You write beautiful code on your Ryzen workstation, only to watch the Raspberry Pi (or similar SBC) throttle its CPU to 600MHz halfway through a make -j4 .
Cross-compiling turns that 45 minutes into . But only if you know the incantations. Step 2: The Toolchain Trap You need a cross-compiler. For S01 (Cortex-A53), I recommend aarch64-linux-gnu-gcc .
ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked Perfect.
Now run a decode test on the S01:
export CC=aarch64-linux-gnu-gcc export CXX=aarch64-linux-gnu-g++ export AR=aarch64-linux-gnu-ar export AS=aarch64-linux-gnu-as Then reconfigure. The build system needs to see the cross-tools for assembly. After make and make install DESTDIR=./rootfs , copy the .so files to your S01.
Run file libvpx.so :
Make sure your environment variables are clean:
Happy compressing. May your S01 stream VP9 without dropping a single frame. P.S. If you try to build for a 32-bit ARMv7 (like the old Pi 2), use --target=armv7-linux-gcc and -mfpu=neon . But honestly? Move to 64-bit. Your A53 will thank you.
