You can set fractions as:
gint num=4;gint den=3;g_object_set( G_OBJECT( crop ), "aspect-ratio", num, den, NULL );

I have a pipeline with element aspectratiocrop. When I tried to set aspect-ratio withstd::string crop_str( "4/3" );
auto crop = gst_element_factory_make( "aspectratiocrop", nullptr );
g_object_set( G_OBJECT( crop ), "aspect-ratio", crop_str.c_str(), nullptr );
the app complains about
passed '0' as denometer for GstFraction.
How to set it properly?
