내 질문은 ffmpeg를 시작하는 데 내 문제에서 비롯됩니다. ffmpeg를 설치했으며 설치된 것으로 표시됩니다.
whereis ffmpeg
ffmpeg: /usr/bin/ffmpeg /usr/bin/X11/ffmpeg /usr/share/ffmpeg /usr/share/man/man1/ffmpeg.1.gz
나중에 일부 프로그램은 설치 자체와 함께 제공되지 않는 라이브러리에 의존하므로 ldd 명령으로 누락 된 항목을 확인했습니다.
# 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)
그것은 ffmpeg가 7 개의 라이브러리에서 잘립니다. 먼저 각 라이브러리를 설치해야한다고 생각했지만, 알아 낸 것보다 일부 또는 전부가 설치 될 수 있지만 해당 위치는 ffmpeg로 알려지지 않았습니다. /etc/ld.so.conf 및 /etc/ld.so.cache에 라이브러리 경로가 포함되어 있지만 한 줄만 있기 때문에 혼란 스러웠습니다.
/etc/ld.so.conf
cat /etc/ld.so.conf
include /etc/ld.so.conf.d/*.conf
그러나 매우 길다 /etc/ld.so.cache
.
나는 지금 내가 더 조사하는 방법을 잃어 버렸다고 생각하는 시점에 있습니다. 이것은 다음 라이브러리를 알아내는 데 도움이 될 것입니다. 해당 위치가 ffmpeg에 알려지지 않은 경우에도 주어진 라이브러리가 실제로 설치되었는지 확인할 수있는 방법입니다.
