android - 如何使用ffmpeg并排创建两个带有填充和图像背景的视频？

Question

使用 ffmpeg 与 collageView 同时播放两个视频。我有代码，但它不能正常工作，请帮助我。

-ss " + getStartTime()  + durationTime_act_select +getVideoUrl() +
                       " -ss " + getStartTime() +
                       " -t " + this.durationTime_act_select +
                       " -i " + getVideoUrl() +
                       " -i " + "R.jpg" +
                       " -filter_complex nullsrc=size=720*720[base1];" +
                       "[0:v]setpts=PTS-STARTPTS,scale=345*700[upperleft];" +
                       "[1:v]setpts=PTS-STARTPTS,scale=345*700[upperright];" +
                       "[2:v]setpts=PTS-STARTPTS,scale=720*720[over];" +
                       "[base1][over]overlay=shortest=1:x=0:y=0[base];"+
                       "[base][upperleft]overlay=shortest=1:x=10:y=10[tmp1];" +
                       "[tmp1][upperright]overlay=shortest=1:x=366:y=10" +
                       " -c:a copy -strict experimental -ss 0 -t " + this.durationTime_act_select + " -preset ultrafast -an " +videoName_act_select

作为您的要求

array2 = (FileUtils.getFFmpeg(SelectedFrameVideos.this) +
                       " -y -ss " + ((Collage) Utils.collageData.get(0)).getStartTime() +
                       " -t " + String.valueOf(this.durationTime_act_select) +
                       " -i " + ((Collage) Utils.collageData.get(0)).getVideoUrl() +
                       " -ss " + ((Collage) Utils.collageData.get(1)).getStartTime()+
                       " -t " + String.valueOf(this.durationTime_act_select) +
                       " -i " + ((Collage) Utils.collageData.get(1)).getVideoUrl() +
                       " -i " + "/storage/emulated/0/R.jpg" +
                       " -filter_complex nullsrc=size=720*720[base];" +
                       "[base][2:v]overlay=1,format=yuv420p[base1];"
                       "[0:v]setpts=PTS-STARTPTS,scale=345*700[upperleft];" +
                       "[1:v]setpts=PTS-STARTPTS,scale=345*700[upperright];" +
                       "[base1][upperleft]overlay=shortest=1:x=10:y=10[tmp1];" +
                       "[tmp1][upperright]overlay=shortest=1:x=366:y=10" +
                       " -c:a copy -strict experimental -ss 0 -t " + String.valueOf(this.durationTime_act_select) + " -preset ultrafast -an " +
                       SelectedFrameVideos.this.videoName_act_select).split(" ");

并排添加两个视频并添加显示在视频填充上的叠加图像您可以更改背景图像“-i”+“/storage/emulated/0/R.jpg”在此处设置您的 bg 图像路径

在下面显示这个视频它是从这个命令创建的
