Sorum, ffmpeg'i başlatma sorunumdan kaynaklanıyor. Ben ffmpeg yükledim ve yüklü olarak görüntülenir:
whereis ffmpeg
ffmpeg: /usr/bin/ffmpeg /usr/bin/X11/ffmpeg /usr/share/ffmpeg /usr/share/man/man1/ffmpeg.1.gz
Daha sonra, bazı programların kurulumun kendisi ile birlikte gelmeyen kütüphanelere bağlı olduğunu anladım, bu yüzden eksik olan ldd komutuyla kontrol ettim:
# 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)
Görünüşe göre benim ffmpeg çok çalışma 7 kütüphaneden kesilir. İlk olarak, bu kütüphanelerin her birinin kurulması gerektiğini düşündüm, ancak anladığım kadarıyla, bazılarının veya hepsinin yüklenebileceğini, ancak konumlarının ffmpeg tarafından bilinmediğini düşündüm. /Etc/ld.so.conf ve /etc/ld.so.cache kitaplıklarının yollarını içerdiğini okudum, ancak kafam karıştı, çünkü içinde sadece bir satır vardı
/etc/ld.so.conf
cat /etc/ld.so.conf
include /etc/ld.so.conf.d/*.conf
ama çok uzun /etc/ld.so.cache
.
Şimdi daha fazla araştırmak için nasıl kayıp hissettim bir noktada, konumu ffmpeg bilinmeyen bile belirli bir kütüphane gerçekten yüklü olup olmadığını belirlemek için nasıl yardımcı olabilir, bir sonraki adım yardımcı olabilir.
