Hi, after most recent array crash (raid10 … and it still corrupted data) I need to scan all the files for errors.
I need ffmpeg for that and it seems there is no easy way for doing that.
Hi @Tomasz_Kusmierz,
so you need to move your cats movies from mov to H.264 uh? 
Hope this will help, found a good guide from ffmpeg.org:
https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

Nope, I’ve got a trick to check whenever all videos are intact by destroyed array:
find -name “*.mkv” -exec sh -c “echo ‘{}’ >> errors.log; ffmpeg -v error -i ‘{}’ -map 0:1 -f null - 2>> errors.log” ;
pretty simple and it works like a charm 
anyway, back to ffmepg - compile it from source ? WTF ? there should be a package … this is what I got from yum
[root@server ~]# yum install ffmpeg

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
You right,
but current ffmpeg is 3.2.4, nux package is 2.6.8-3 and compiling from source you solve all dependencies issues 
EDIT:
Always had ffmpeg from source on Debian family (Debian/Ubuntu) too because of those kind of issues
M.
@phillxnet & @suman : do we have elrepo on our envs? O_o…tested on my Rockstor testing machine and no elrepo
@Flyer I might have adde elrepo to use kernel 4.9 against problem I’ve had with my array. Anyway I don’t care about any extra packages - I need bare ffmpeg to crawl through mkv files and check their consistency.
BTW, I would sugest pushing kernel to 4.10 because 4.8 has a serious problem with snapshots and qgroups that in my case resulted in FS falling back to RO on snapshot creation (kernel ops) and then in FS crashing whole system on mount. (and AFAIK they did not fix it in 4.9)
