makemkv Blu-Ray extraction exceptionally slow with Centos 7
Posted: Wed Sep 23, 2015 8:54 pm
I have purchased makemkv and hoped to use it on my Centos 7 home server to extract mkv files from blu-ray disk images I have as ISO's (made with Slysoft).
When I use makemkv on Centos 7, it sees the ISO and attempts to extract it. But it then the time to do this extraction is enormous (many hours). It really makes very slow progress, I haven't had the patience to see if it's even generating a valid file.
But when I access the same image i.e the same file on the Centos 7 machine via NFS to a Fedora 22 client machine and run makemkv on that it works very quickly (about 15 minutes).
The Centos 7 machine is much much higher spec than the Fedora 22 (a core 2, 4GB RAM machine vs a Xeon with 32 GB of RAM). And the Centos 7 machine is accessing the Blu-Ray image directly not via NFS. I just don't get it.
I have tried the makemkv in the nux repo, the "schotty" one from the forum, Fedora 21 RPM's and a hand built one with the latest FFMPEG.
Anyone seen this? Or can provide any insight?
There are some warnings on the output:
The source file '/BDMV/STREAM/00000.m2ts' is corrupt or invalid at offset 2112215040, attempting to work around.
But both the Fedora version and the Centos 7 version generate these and the output seems okay from the Fedora system.
