FFmpeg Android compilation : command not found
18 février 2019, par maxestSo I’m trying to build, on Ubuntu, FFmpeg from sources. Here’s a script I assembled from here and there :
#!/bin/bash
NDK=$HOME/Desktop/adt/android-ndk-r19b
SYSROOT=$NDK/platforms/android-26/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64
function build_one
{
./configure
--prefix=$PREFIX
--arch=arm
--target-os=linux
--enable-cross-compile
--cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi-
--sysroot=$SYSROOT
--extra-cflags="-Os -fpic $ADDI_CFLAGS"
--extra-ldflags="$ADDI_LDFLAGS"
$ADDITIONAL_CONFIGURE_FLAG
make clean
make -j9
make install
}
CPU=arm
PREFIX=$(pwd)/android/$CPU
ADDI_CFLAGS="-marm"
build_oneUnfortunately I get a list of following outputs :

because there were no folderandroid/arm

I'm trying to make the zoom video using image but facing


TypeError: must be real number, not NoneType.



It used was to run but I don't remember if I might have updated numpy, ffmpeg, or any thing else that is now causing the error. I have tried the code on python 3.10 and 3.11 and get the same error in both. I was previously running it on python 3.10.
