新人求助 添加水印命令出错

jihuai

我测试使用的源码是cumulusclips它的后台设置H.264 Encoding 就可以添加水印


原始H.264 Encoding是
-vcodec libx264 -vf "scale=min(640\,iw):trunc(ow/a/2)*2" -vb 800k -ab 96k -ar 44100 -f mp4
官方论坛给出加水印方法是
-vf "后添加 movie=/full/path/to/watermark_image.png [watermark]; [in][watermark] overlay=10:10 [out]
下边是官方论坛帖子地址 http://cumulusclips.org/forums/discussion/1178/watermark-on-videos
--------------------------------------------------------------------------------------------------------------------------------------------
我按照官方方法添加之后
-vcodec libx264 -vf "movie=/www/wwwroot/watermark.png [watermark]; [in][watermark] overlay=10:10 [out], scale=min(640\,iw):trunc(ow/a/2)*2" -vb 800k -ab 96k -ar 44100 -f mp4

上传视频出现错误，错误如下
Simple filtergraph 'movie=/www/wwwroot/watermark.png [watermark]; [in][watermark] overlay=10:10 [out], scale=min(640\,iw):trunc(ow/a/2)*2' was expected to have exactly 1 input and 1 output. However, it had >1 input(s) and >1 output(s). Please adjust, or use a complex filtergraph (-filter_complex) instead.Error reinitializing filters!Failed to inject frame into filter network: Invalid argumentError while processing the decoded data for stream #0:0Conversion failed!刚刚接触ffmpeg，百度谷歌搜了一天了，没有找到解决办法，希望大神指点一下，不胜感激。

-filter_complex  看提示说是用这个替代-vf的建议，试试看

谢谢回复，找到原因了，[out]位置错了。

一个问题接一个问题
我想继续添加字幕，
-vcodec libx264 -vf "drawtext=fontfile=default:text=‘aaaaaaaaa’, movie=/www/wwwroot/watermark.png [watermark]; [in][watermark] overlay=10:10, scale=min(640\,iw):trunc(ow/a/2)*2[out]" -vb 800k -ab 96k -ar 44100 -f mp4

得到错误

看错误提示的意思好像是没找到字体

谢谢大师兄，是的没有字体，如果在文字中添加当前的日期应该添加什么

变量，可以在播放器里面做，也可以在编码器里面做，播放器里面做的话是不影响影片的，编码器里面做的话，可能会打到视频图像里

大师兄，能给我个变量吗？现在水印字幕能一次加了，就是没找到这个变量
