有人可以請幫我一個關於如何在Linux上安裝FFMPEG
的工作方法,我遵循了幾個教程,他們似乎工作,除非在系統中找不到任何FFMPEG
,即使在幾個系統重新啓動我的最後一次嘗試是從這個鏈接Compile FFmpeg on Ubuntu, Debian, or MintOpenCV linux如何安裝FFMPEG
我做教程的一切,但是當我運行man ffmpeg
它告訴我,沒有手動發現OpenCV
也沒有檢測到它,我打過電話了Core.getBuildInformation()

它仍然不能檢測'FFMPEG' –
你能嘗試刪除build文件夾並重新運行cmake的?這些可能有ffmpeg版本,比如libavformat-ffmpeg-dev等,你可能也想安裝它們。 –
好吧,讓我再試一次 –
