मेरा सवाल ffmpeg शुरू होने में मेरी समस्या से उत्पन्न होता है। मैंने ffmpeg स्थापित किया है और इसे इंस्टॉल के रूप में प्रदर्शित किया गया है:
whereis ffmpeg
ffmpeg: /usr/bin/ffmpeg /usr/bin/X11/ffmpeg /usr/share/ffmpeg /usr/share/man/man1/ffmpeg.1.gz
बाद में, मुझे पता चला, कि कुछ प्रोग्राम पुस्तकालयों पर निर्भर करते हैं जो स्वयं इंस्टॉलेशन के साथ नहीं आते हैं, इसलिए मैंने ldd कमांड के साथ जाँच की कि क्या गायब है:
# ldd /usr/bin/ffmpeg
linux-vdso.so.1 => (0x00007fff71fe9000)
libavfilter.so.0 => not found
libpostproc.so.51 => not found
libswscale.so.0 => not found
libavdevice.so.52 => not found
libavformat.so.52 => not found
libavcodec.so.52 => not found
libavutil.so.49 => not found
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f5f20bdf000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f5f209c0000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5f205fb000)
/lib64/ld-linux-x86-64.so.2 (0x00007f5f20f09000)
जैसा कि यह पता चला है कि मेरा ffmpeg 7 पुस्तकालयों से भी कटा हुआ है। मैंने पहले सोचा था कि उन पुस्तकालयों में से प्रत्येक को स्थापित किया जाना है, लेकिन जितना मुझे पता चला है, कि कुछ या सभी स्थापित हो सकते हैं, लेकिन उनका स्थान अनजान है ffmpeg। मैंने पढ़ा कि /etc/ld.so.conf और /etc/ld.so.cache में पुस्तकालयों के रास्ते हैं, लेकिन मैं उलझन में था, क्योंकि, वहाँ केवल एक ही लाइन थी
/etc/ld.so.conf
cat /etc/ld.so.conf
include /etc/ld.so.conf.d/*.conf
लेकिन बहुत लंबा है /etc/ld.so.cache
।
मैं अब एक ऐसे बिंदु पर हूं, जहां मुझे लगता है कि आगे की जांच कैसे की जाए, यह पता लगाने के लिए एक उपयोगी अगला कदम हो सकता है, मैं यह कैसे निर्धारित कर सकता हूं कि यदि दी गई लाइब्रेरी वास्तव में स्थापित है, भले ही उसका स्थान ffmpeg के लिए अज्ञात हो।
