Still, when I copied our av1.webp profile under different name and replaced libaom part of first line with libsvtav1 (and removed rest of options) encode never finished? It never made it past 96% Not sure if it was termux-specific or cingg in general does not work with this specific encoder? I also tried rav1e in same way - using shared ffmpeg build already available on termux. It also not worked :( > > > > > >
