未找到 FFmpeg 重映射过滤器

Question

我正在尝试使用此处描述的方法拼接 360° 图片:
https://trac.ffmpeg.org/wiki/RemapFilter#no1

这是我使用的命令:

ffmpeg -i 360_0008.JPG -i xmap_samsung_gear_2560x1280.pgm -i ymap_samsung_gear_2560x1280.pgm -lavfi remap out.png

和我得到的错误:

我错过了什么？还是为 Ubuntu 16.04 打包的 ffmpeg 中缺少什么？

Answer 1

我自己也遇到了这个问题，重新映射过滤器是在 ffmpeg 3.1 中引入的，奇怪的是 ubuntu 16.04 默认没有 repos，为了让 ffmpeg 3 在 ubuntu 16.04 上工作，请遵循本指南，它对我有用:

http://ubuntuhandbook.org/index.php/2016/09/install-ffmpeg-3-1-ubuntu-16-04-ppa/

编辑:

但基本上，您需要将它们放入 linux 终端(我使用 16.04 Ubuntu 进行了测试)

sudo add-apt-repository ppa:jonathonf/ffmpeg-3
sudo apt-get update
sudo apt-get dist-upgrade

然后我更喜欢:

sudo apt-get autoremove

但请记住，正如页面上所述，某些程序可能依赖于旧的 ffmpeg2 库，因此您需要根据需要对其进行研究。

希望这可以帮助 :)
