Disable mediainfo to gain scan speed

[TekDes]

Same here, I have something like 400gb of movies, 100gb of music and 20gb of pictures and the NMJ scan just never ends!
I left it on for more the 24hrs but then I gave up and brutally switch my pch off and on again!

During those hickups, I noticed that mediainfo was running... The bad news is, you cannot rename mediainfo in the /opt/syb/app/bin directory since it is readonly...
So I looked at the PATH environment value, and saw that the /bin directory is the first one. So I created a empty executeable mediainfo file in the bin directory and started the scan again. The result was a big improvement... no more hickups on specific files!
Mediainfo is needed for the resolution, codec and duration info of video's in NMJ. Without mediainfo, audio files don't get added to NMJ. So I created a oneliner that executes the real mediainfo when a audio file is scanned.

This is only a proof of concept, and I think the real problem lies in the fact that NMJ tries to execute mediainfo always on files that mediainfo had problems with (the hickups). So we basically need a script that checks if mediainfo already was runned on a file... but I will look into that later...

For now, try these commands in lundmannshell for those who are interested (or add them to the end of start_app.sh, to make them reboot persistent):

Code:

echo 'if [[ "$*" == *udio* ]]; then /opt/syb/app/bin/mediainfo "$@"; fi'> /bin/mediainfo
chmod +x /bin/mediainfo

if you want to see the mediainfo parameters the scan executes, you can execute

Code:

echo 'echo $* >> /share/mediainfo.txt' >>/bin/mediainfo

where /share/mediainfo.txt is the output file...

Please let me now if this works for you! (hickups with no networkactivity on video files = mediainfo slowdown)

Edit: used lordy's suggestion

Hi

Ive been trying to get this to work. installed the shell to get .sh file in share and then notepad++ to edit it. this is what my last lines now look like.
---------------------------------- - this line is not in the .sh
#M_A_R_K_E_R_do_not_remove_me
echo 'if [[ "$*" == *udio* ]]; then /opt/syb/app/bin/mediainfo "$@"; fi'> /bin/mediainfo
chmod +x /bin/mediainfo


exit 0
---------------------------------- - this line is not in the .sh
I then saved it and cold-booting the PCH. I then tried deleting my old db and ran a new scan (on .avi tv series only). and its working fine but takes about the same time as normal which is 24 hours for my db.

have i made an error or shall I do something else to get it to work

it seems ok, did you reboot?

The speed gain is probably not great in the new 8 or 17 december firmware since it is more optimized...

Yeah I rebooted.

heh if its optimized then it still have a looong way until its acceptable. I can live with a 24h scan on a new db but i cannot accept it takes as long just to add 1 new series. that should take 10 mins and NOT rescan all the other 117 series again (and even FUBAR a lot of them in the process
