I am trying to add image overlay on video using "mobile-ffmpeg-full-gpl:4.4" library but faced 'Error when evaluating the expression 'between(t' for enable' error.
I have a class that create overlay filter for adding image:
`class ImageFilter {
static String getFilter(String input, String output, ArrayList<ExtraTL> listImage, int order){
String filter="";
for (int i=0; i<listImage.size(); i++){
ImageHolder image = listImage.get(i).imageHolder;
int index = i+order;
String in = i==0?input:"[out"+index+"]";
String out = i==listImage.size()-1?output:"[out"+(index+1)+"];";
filter += prepareImage(image, index);
filter += addImage(in, out, image, index);
}
return filter;
}
private static String prepareImage(ImageHolder image, int index){
return "["+index+":v]scale="+image.width+":"
+image.height+",rotate="+image.rotate+":c=none:ow=rotw("+image.rotate
+"):oh=roth("+image.rotate+")[ov"+index+"];";
}
private static String addImage(String input, String output, ImageHolder image, int index){
return input+"[ov"+index+"]overlay="+image.x
+":"+image.y+":enable=between(t,"+image.startInTimeLineSec +","
+image.endInTimeLineSec +")"+output;
}`

Also my log when I run program is:

How can I resolve this error?
Thanks...
