使用 mobile-ffmpeg android 在两次视频之间叠加图像

Question

我正在尝试使用“mobile-ffmpeg-full-gpl:4.4”库在视频上添加图像叠加，但遇到以下错误

评估启用表达式“between(t)”时出错

我有一个创建用于添加图像的覆盖过滤器的类：

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;
    }

使用的FFMPEG命令：

-loop 1 -i /storage/emulated/0/OP_Video_Editor/.temp/background.png -ss 0.0 -t 21.18 -i /storage/emulated/0/OP_Video_Editor/.temp/1614097633623.mp4 -i /storage/emulated/0/OP_Video_Editor/.resource/sticker_i02.png -filter_complex [1:v]crop=640:360:0:0[crop];[crop]scale=1280:720[v_scale];color=black:1280x720,fps=30[bgr0];[bgr0][0:v]overlay[bgr];[bgr][v_scale]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2:shortest=1[v1];[1:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=1.0[a1];[v1][a1]concat=n=1:v=1:a=1[v][a];[a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=1.0[a0];[a0]amix=inputs=1:duration=longest:dropout_transition=1[outAudio];[2:v]scale=333:333,rotate=-0.0:c=none:ow=rotw(-0.0):oh=roth(-0.0)[ov2];[v][ov2]overlay=333.33334:333.33334:enable=between(t,0.0,10.0)[inText] -map [inText] -map [outAudio] -format yuva420p -preset ultrafast -video_track_timescale 90k -b:v 2000k -c:v libx264 -bufsize 64k -c:a aac -bsf aac_adtstoasc -strict -2 -y /storage/emulated/0/videoExport/videoplayback_22_21_28_18_44_10.mp4 

我运行程序时的日志也是：

 E/mobile-ffmpeg: [overlay @ 0xdfa96880] [Eval @ 0xc3f5eb70] Missing ')' or too many args in 'between(t'

 E/mobile-ffmpeg: [overlay @ 0xdc5f3b80] Error when evaluating the expression "between(t" for enable'

 E/mobile-ffmpeg: [AVFilterGraph @ 0xc74469c0] Error initializing filter 'overlay'

 E/mobile-ffmpeg: [AVFilterGraph @ 0xc74469c0]  with args '333.33334:333.33334:enable=between(t'

我该如何解决这个错误？
