Question

我已经在我的Android Studio上编译了https://github.com/WritingMinds/ffmpeg-android-java，它运行正常，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};

现在我想结合这三个我如何实现这一目标？到目前为止，我已尝试使用文本填充：

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};

但是我收到了这个错误：

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;

我能够自己解决这个问题，因为人们想知道同样的问题，因为这是一个复杂的问题，这里有：

def youtube_search(q, max_results):  # old version: def youtube_search(options):
  youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION,
    developerKey=DEVELOPER_KEY)

  # Call the search.list method to retrieve results matching the specified
  # query term.
  search_response = youtube.search().list(
    q=q,  # old version: q=options.q,
    part="id,snippet",
    maxResults=max_results # old version: maxResults=options.max_results
  ).execute()
