That's what Stephance suggested: > So my advice is to add a 3rd digit to your time values and to replace, for > instance, eq(t\,47.96) by something like between(47.963\,t-0.002\,t+0.002).

Probably you need another operator, such as timefromstring(): select='eq(t\,timefromstring(1:23))' (Perhaps need to replace ":" with "\:", I don't remember.) I'm not sure whether expressions actually work with string values, though. > -Ulf Moritz _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
