h264enc for Linux

[froggy1]

Have you already tried the two xbox presets available (mx and mxhq) ? They don't work? I don't see anything special in the above settings that'll make the already present xbox presets in the script incompatible. The only thing is that CABAC is disabled while I have it enabled in the xbox presets. Maybe xbox1 can't take CABAC?

[mrplow]

Those are xbox360 presets and to tell you the truth I tried them many revisions ago and many xbmc revisions ago and at the time it would stutter from time to time in high action scenes. But that was a while ago and I could try them again this weekend.
It seems the xbox1 can only handle CABAC if Deblocking is disabled and visa versa. With CABAC on and deblocking off the video is better quality but larger and with CABAC off and deblocking on the quality goes down slightly along with the file size.

[froggy1]

hmm, CABAC is supposed to increase compression more than CAVLC so I'm a bit at a loss why you get smaller file sizes when you disable it. If I add such a preset, then I'll only disable CABAC but leave deblocking on. Can you try the xbox presets again on a short sample and see if you still get problems with them on the xbox1?

Hi,

I have a multi core cpu I was wondering if there is an option I need to be setting to make the encode multi-threaded? I got h264enc off the Karmic repository today (version 9.0.0) and am trying out a test encode but it is currently only using a single core. A quick search of this thread and the man pages hasn't revealed anything to me ... :-(

Thanks in advance.

First of all, I'd recommend getting MPlayer/MEncoder SVN, built against a recent libx264 version and then the latest h264enc version. Ubuntu provides oldish versions of these programs.

Multithreading should work with those versions too, but maybe froggy1 can guess what's going on.

[froggy1]

the threads=auto option is always used in h264enc so it should work. As nm said, get latest stuff from SVN/git/whatever

[daniel.pool]

Froggy1, nm,

Thanks for the really fast reply guys.

I've got the latest x264 from git, but I'm currently unable to get the latest mplayer from svn, one of the dependencies (I'm using this guide on compiling mplayer-nogui, so maybe I'm building completely the wrong thing) has a broken deb. I've got a bug raised against it, so for now the only way I've been able to get h264enc working is to go with what is coming from rvm's ppa (https://launchpad.net/~rvm/+archive/testing).

I'll try upgrading as soon as a fix is made available for the deb (or someone points out I'm being thick and get pointed to the right guide for compiling on Karmic )

[froggy1]

what is this broken dependency? Just go to mplayer's site, get SVN link, and pull from there. That's what I always to (though I have a script called getprog which accepts params about which software to pull from SVN, something small I've written to east it for me)

To quote Andrew from the Ubuntu forums:

By default Ubuntu does not offer a particularly rich development environment so we need to download the required 'dev' files which are specific to Intrepid Ibex. (These files are loosely modelled on the results of the command 'sudo apt-get build-dep mplayer-nogui', I have removed some files and added others.)

The dep that was failing me was libopencore-amrnb0, as stated, there is a bug raised against it.

However, as it turns out in researching these links to reply to you (and running the apt-get command again to try and get the error), the dependencies now actually install, which means my compilation should succeed! Huzzah.

So, I'll grab the latest h264enc once I've got the latest mplayer. Will update this with my results. Thanks very much for your help.

Thanks

This is why I don't use Ubuntu! They got to have the most incompetent packagers out there :P
I'm a packager myself but luckily not for Ubuntu...

So then... compile everything, first x264 then mplayer, and see if you get threading problems. Make sure to run h264enc -r to reset its config file

[daniel.pool]

Gaah, it's still only running on a single core

I'm pretty sure that it's not an option I've selected (I've attached my options file just to make sure).

I'm going to call it a day on this, but will look at it again tomorrow evening. I'm guessing the best way would be to call the encoder directly from the command line and see what is happening there. Is it mencoder called, or ffmpeg?

Cheers,

[froggy1]

better post attachments to an external site as it can take here some time before they get accepted by a mod
as for the threading. I don't have problems, neither other users who have reported that it works

Im getting errors after updating h264enc, mencoder, mplayer and ffmpeg.

@kripz

Look at the top, your libx264 is not new enough as it's missing weightp option. Pull latest x264 from git and compile it, then you may need to recompile mplayer and make sure it's linked to it, not to another older libx264 if you have one on your system

[WalterK]

yeah folks dont forget to keep x264 updated as well as mencoder and mplayer.

[kripz]

lol i totally missed that line

edit: those patches on your website are very outdated?

edit2: Doesnt look right...
