:FFMPEG ölçek ve kırpma aşağıdaki lib kullanarak Android'de FFMPEG kullanıyorum

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

bu Amacım ölçeklemektir: http://writingminds.github.io/ffmpeg-android-java/

Bu kullanıyorum komut görüntü 480x360'a kadar düşer, ardından (0,0) (sol üst köşeden) 360x360'a kırpın. NASIL, sonuç olarak ortaya çıkan şey, dikey merkezden koparılmasıdır. Öyleyse, örneğin, ekranın tamamını dolduran birbirinin üstüne üç blokluk bir vilay alacak olsaydınız, en üstteki bloğu arzuladığım halde, ürün eninde sonunda sadece orta bloğu gösterirdi.

Hata yaptığım şey hakkında bir fikriniz var mı?

Tüm bunlardan nihai amacım 360x360 boyutunda bir kare video elde etmektir.

Çıktı günlüğü: Kaynağınız Video 90 döndürülür

Mayıs 2015 veya sonrası gelen ffmpeg sürümleri ile, orijinal piksel matrisi rotasyon reset ile

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

"-noautorotate -i " + path + \

-strict -2 -preset ultrafast -metadata:s:v rotate=0" + fileOutPath

Daha eski sürümler için, oto rota bayrakını atlayın.
