我正在尝试将文字设置为已录制视频的水印,但它无效。当我尝试将image.png作为水印时,按照此网址http://androidwarzone.blogspot.in/2011/12/ffmpeg4android.html
进行操作在已录制视频上将图像应用为水印的命令:
String[] complexCommand = {"ffmpeg","-y" ,"-i", videoPathHere,"-strict",
"experimental", "-vf", "movie="
+ Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/watermarkImg.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]",
"-s", "160x120","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab", "48000",
"-ac", "2", "-ar", "22050",
Environment.getExternalStorageDirectory().getAbsolutePath()+"/watermark.mp4"};
但是当我尝试将文本作为水印实现时,它无效:
String[] complexCommand = {"ffmpeg", "-y" , "-i", videoPathHere, "-strict", "experimental",
"-vf", "drawtext=fontfile=" + file + ":text=TestText", "-s", "160x120", "-r", "30",
"-b", "15496k", "-vcodec", "mpeg4", "-ab", "48000", "-ac", "2", "-ar", "22050",
Environment.getExternalStorageDirectory().getAbsolutePath()+"/watermark.mp4"};
但它在我的情况下也不起作用。
那么,将文本添加为水印会出现什么问题?
我在commenad中进行了更改; text = TestText到:text = TestText然后显示给定的错误。

答案 0 :(得分:0)
这个 - ";text=TestText"
应为":text=TestText"
