    I fixed this issue by building openh264 from the source. I chose the version v2.0.0 which creates the libopenh264.so.5 shared object file. Newer versions created objects like libopenh264.so.7 and didn't work.

    git clone -b v2.0.0 https://github.com/cisco/openh264
cd openh264
make -j4
sudo make install
ls /usr/local/lib
# libopenh264.so.5 ........
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
ls ${PKG_CONFIG_PATH}
#openh264.pc
