मुझे मूवी फाइलों से बंद कैप्शन जानकारी निकालने की ज़रूरत है, मैंने ccextractor को आजमाया है लेकिन ऐसा लगता है कि यह काम नहीं कर रहा है।मूवी फाइलों से बंद कैप्शन निकालने का सबसे अच्छा तरीका क्या है?
मैंने एक वीडियो स्ट्रीम (इसमें बंद कैप्शन के साथ) पर कब्जा कर लिया है और फ़ाइल में सहेजा गया है और फिर मैं ccextractor चलाता हूं ... लेकिन यह कुछ भी नहीं मिल रहा है!
मेरे वीडियो नमूने में नीचे हैं:

पहला प्रयास:
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}"

इस सवाल के रूप में, प्रोग्रामिंग के साथ कुछ भी नहीं है। इस विषय पर एक प्रश्न हो सकता है जो प्रोग्रामिंग से संबंधित है, लेकिन यह सवाल बंद कैप्शनिंग निकालने के लिए उपकरण खोजने के बारे में है, न कि बंद कैप्शन को निकालने वाले टूल को कैसे लिखना है। – Makyen
