### This is a fresh git clone of ffmpeg from its official git repo @ https://github.com/ffmpeg/ffmpeg 
### snapshot is from 17.04.2026 

### Building on QNX 8.0  

### Make sure you move away the bundled ffmpeg libs from /usr/lib/ first !!! 

libavcodec
libavdevice
libavfilter
libavformat
libavutil
libswresample
libswscale

### Make sure you copy from the cross-environment (earlier QNX 8.0 build environment) the ALSA includes /usr/include/alsa  
    since the QNX 8.0 Development Desktop is missing them for some reason and I cannot upload these here due to licensing 
    issues 

### Add this new alsa.pc to /usr/lib/pkgconfig 

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: ALSA
Description: Advanced Linux Sound Architecture (QNX port)
Version: 1.2.0
Libs: -L${libdir} -lasound
Cflags: -I${includedir}
Requires.private: 


### Then proceed to build ffmpeg 

wget https://astr0baby.online/QNX/8.0-DEVELOPER_DESKTOP/RPi4_aarch64/MPV/FFMPEG/ffmpeg.tar.gz
tar -zxvf ffmpeg.tar.gz 
cd ffmpeg

#### Now please note the hacks in the .so copy procedures , on QNX there are issues with autogenerating sonames and appropropriate symlinks 
#### during builds like ffmpeg (this is at least my observation) so when ffmpeg build process hits the linking stage towards libavutil.so do the 
#### hack above with copyting the compiled library in the full soname format to its simplified one line libavutil.so.60 -> libavutil.so and so on ...
