Film dosyalarından kapalı altyazı bilgisi almam gerekiyor, ccextractor denedim ama işe yaramıyor.Film dosyalarından kapalı altyazı elde etmenin en iyi yolu nedir?
Bir video akışını yakaladım (içinde kapalı başlık var) ve bir dosyaya kaydedildim ve sonra ccextractor'u çalıştırıyorum ... ama hiçbir şey bulamıyor!
My Video örneği aşağıdadır:

Önce şunu deneyin:
cvlc -I dummy v4l2:///dev/video1:width=720:height=480:norm=ntsc:standard=ntsc:pixelformat=2:aspect-ratio=4\:3:channel=0 --sout "#transcode{vcodec=mp2v}:standard{access=file,mux=dummy,dst=gsd.mpg}"

Bu soru formüle edilmiş olarak, programlama ile ilgisi yoktur. Bu konuda programlama ile ilgili bir soru söz konusu olabilir, ancak bu soru, kapalı altyazıların çıktısını almayı amaçlayan araçların nasıl yazılacağı hakkında değil, altyazıyı çıkarmak için araçlar bulmakla ilgilidir. – Makyen
