FFMPEG規模和作物單一命令

2016-03-25 99 views

我使用FFMPEG在Android上使用下面的lib：http://writingminds.github.io/ffmpeg-android-java/FFMPEG規模和作物單一命令

這是我使用的命令：

"-i " + path + " -vf scale=480:360,crop=360:360:0:00 -strict -2 -preset ultrafast " + fileOutPath

我的這個目標是擴展將圖像降至480x360，然後從（0,0）（左上角）將其裁剪爲360x360。然而，最終發生的是它從垂直中心收穫。舉個例子，如果你要在整個屏幕上拍攝三塊互相重疊的圖塊，作物最終將顯示出中間塊，而我希望上塊。

任何想法，我做錯了什麼？

我的最終目標是獲得360x360大小的方形視頻。

源視頻旋轉90！

使用，具有原始像素矩陣

-vf scale=480:360,crop=360:360:120:0

隨着旋轉復位，與ffmpeg的版本從2015年或更高版本可能。

"-noautorotate -i " + path + \ 
" -vf scale=480:360,transpose=2,crop=360:360:0:0 
-strict -2 -preset ultrafast -metadata:s:v rotate=0" + fileOutPath

對於舊版本，請跳過noautorotate標誌。

不，這不是：/是什麼讓你這麼說？ –

這個：「顯示矩陣：90.00度的旋轉」 – Mulvya

我希望你是對的:(這只是水平拉伸我的視頻 –
