【求助】用ffmpeg如何同时去掉两个不同位置的logo?

[foxme]

现在的视频打很多logo, 上下左右几乎都有.

去掉单独位置的logo我可以使用: -vf delogo

我想使用ffmpeg同时去掉 右上 和 右下 两处的logo, 尝试了下面的语句:

ffmpeg -i .\sample.mp4 -vf "delogo=x=649:y=18:w=188:h=64, delogo=x694:y=406:w=145:h=63" -c:a copy output2.mp4

但是返回错我信息:

请问是不是ffmpeg不支持同时使用两个delogo? 如果支持的话, 该怎么写呢?

命令写错了 少了个=号

ffmpeg -i .\sample.mp4 -vf "delogo=x=649:y=18:w=188:h=64, delogo=x=694:y=406:w=145:h=63" -c:a copy output2.mp4
