繼承人的命令:我的FFMPEG轉換器不允許mp4進行webm轉換。
ffmpeg -i videos/test.mp4 -c:v libvpx -level 216 -profile 0 -qmax 42 -qmin 10 -c:a libvorbis -f webm out.webm
我不斷收到此錯誤:
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
這裏是全響應
# ffmpeg -i videos/test.mp4 -c:v libvpx -level 216 -profile 0 -qmax 42 -qmin 10 -c:a
libvorbis -f webm out.webm

沒有任何人有任何想法怎麼回事?我完全失去了。我嘗試了很多不同的命令。從mp4到ogg的轉換工作正常,我已經有mp4到webm工作,但我重新安裝ffmpeg讓mp4到ogg工作,現在我的mp4轉換爲webm。 >。這整個安裝過程是如此惡夢般的噩夢。有沒有人有一個很好的教程,爲mp4 ogg和webm工作的ffmpeg的centos安裝?我使用了ffmpeg網站下載的centos tut,但它讓我失望了。如果任何人有任何想法可以指出我正確的方向,我將非常感激!
有關使用FFmpeg命令行的問題是堆棧溢出的主題。請在將來向[SU]提問。 (但請不要交叉發表這一個) – slhck
