android - 在 FFMPEG Android Studio 上运行多个命令

Question

我已编译https://github.com/WritingMinds/ffmpeg-android-java在我的 Android Studio 上，它工作正常，我已经成功执行了这 3 个命令:

添加文字:

new String[]={"-i",file1.toString(), "-i", water,"-filter_complex","drawtext=fontsize=60:fontfile=/system/fonts/DroidSans.ttf:fontcolor=green:text=AAAA:x=(w-tw)/2:y=(50-th)/2", final_output}

添加水印:

new String[]{"-i",inputVideoFilePath, "-i",overlayImagePath,"-preset", "ultrafast","-filter_complex", "overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2", "-codec:a", "copy", outputVideoFilePath

添加填充:

 new String[]{"-i",file1.toString(), "-i", water,"-filter_complex","[0:v]pad=iw:ih+100:0:(oh-ih)/2:color=white", final_output2};

现在我想将这三个结合起来，我该如何做到这一点？到目前为止，我已经尝试用文本填充:

new String[]{"-i",file1.toString(), "-i", water,"-filter_complex","[0:v]pad=iw:ih+100:0:(oh-ih)/2:color=white","drawtext=fontsize=60:fontfile=/system/fonts/DroidSans.ttf:fontcolor=green:text=AAAA:x=(w-tw)/2:y=(50-th)/2", final_output2};

但我得到这个错误:

Input #1, png_pipe, from '/storage/emulated/0/watermark.png':
Duration: N/A, bitrate: N/A
Stream #1:0: Video: png, rgb24(pc), 200x125, 25 tbr, 25 tbn, 25 tbc
[NULL @ 0xb5c9fc00] Unable to find a suitable output format for
'drawtext=fontsize=60:fontfile=/system/fonts/DroidSans.ttf:fontcolor=green:text AAAA:x=(w-tw)/2:y=(50-th)/2'
 drawtext=fontsize=60:fontfile=/system/fonts/DroidSans.ttf:fontcolor=green:text=AAAA:x=(w-tw)/2:y=(50-th)/2: Invalid argument

任何形式的帮助都会很棒!

您可以使用以下命令添加文本、水印和填充:-

                " -i "+VideoPathonSdCard+" -i "+ImagePath+" -metadata:s:v rotate=0 -filter_complex vflip,transpose=0,overlay=(W-w)/2:(H-h)/2,pad=iw:ih+100:0:(oh-ih)/2:color=white,drawtext=fontsize="+TextSize+":fontfile=/system/fonts/DroidSans.ttf:fontcolor="+hexColor+":text="+ Text+":x="+x+":y="+y+"+40 -y -preset ultrafast -strict -2 "+VideoAfterEdit_Path;
