Dual core issue and how to reset encoders back to default?

[monkey]

Hi,

I've been trying to add "-threads 2" to my encoders, but for some reason it's not working

Here's what I've currently got as my mpeg transcoder

Code: Select all

ffmpeg -threads 2 -ss %o -i %s -async 1 -b %bk -s %wx%h -ar 44100 -ac 2 -v 0 -f flv -

OK, I should have tested this out on a couple of encoders first, but I didn't

Now when I remove the threads 2 option, I'm getting access denied errors on the movies that previously played OK

So, firstly, how can I easily reset my encoders back to their defaults?
Secondly, any idea why ffmpeg isn't playing nicely with a dual core processor (Ubuntu Oneric Server) ?

Here's the error log

Any ideas? Thanks in advance!

I was having a simular problem (running 10.04 though). Follow the guide in the ubuntu wiki to update ffmpeg and add in all the optional stuff in the guide. once it's done you have to change the symlink in /var/subsonic/transcoders/ for ffmpeg to the new install location. once that's done use this

Code: Select all

ffmpeg -ss %o -i %s -async 1 -b %bk -s %wx%h -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset fast -threads 0 -

Hope that helps.
