Well, then something is wrong with your ffmpeg version. Please post a full command line and complete, uncut console output from a reproducible attempt. Your expression works fine for me on Linux with said quotes (though I'm not sure it makes sense): $ ffmpeg -f lavfi -i testsrc -c:v libx264 -t 100 -force_key_frames "expr:gte(t,n_forced*5)" -f null - [I'm not quoting the output here. I simply don't get an error.] Moritz _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
