Correct. This fails, as mentioned by Kaled: $ ffmpeg -f lavfi -i anoisesrc=seed=0 -f lavfi -i anoisesrc=seed=42 -map 0 -map 1 -c:a:0 libmp3lame -strict experimental -c:a:1 dts -bsf:a dca_core -t 10 -f null - This succeeds: $ ffmpeg -f lavfi -i anoisesrc=seed=0 -f lavfi -i anoisesrc=seed=42 -map 0 -map 1 -c:a:0 libmp3lame -strict experimental -c:a:1 dts -bsf:a:1 dca_core -t 10 -f null - Cheers, Moritz _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
