That's because the drawbox filter does not know anything about text_w or text_h. Also w and h are the desired box dimensions not the dimensions of the video. And BTW, x should be 0, if you want the box to span from the left to the right edge of the frame. Also, you can omit w if the box shall span the video width. Have a look at which constants this filter accepts. Here is an example that works: drawbox="y=(ih-h):h=30:color=black@1:t=max" _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
