FFMPEG build still resulting in Illegal instruction on raspberry pi ZERO, but not PI 2+
3 mai 2017, par zyeekThe process in which I do it configures the lib and ffmpeg files on the zero then move over to a pi 3 to make and install it (for speed).
Build process :
# x264
git clone git://git.videolan.org/x264.git
cd x264
sudo ./configure --host=arm-unknown-linux-gnueabi --enable-shared --disable-opencl
sudo make
sudo make install
sudo ldconfig
# FFMPEG
git clone git://source.ffmpeg.org/ffmpeg.git
cd ffmpeg
sudo ./configure --arch=armel --target-os=linux --enable-gpl --enable-libx264 --enable-nonfree
sudo make
sudo make installI tried following this cross compile type build but complained I was missing a C compiler, but GCC was installed. SO I just went to follow my previous method.
