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 使用 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

根据您的要求

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上的叠加图像填充您可以在此处更改背景图像“-i”+“/storage/emulated/0/R.jpg”设置背景图像路径
