Compiling PS3 Media Server on OSX

[Redlum]

Awesome, thanks I'll test it this weekend.

This means the patch needs rewriting

Since this is a workaround for an MEncoder issue that might affect any platform using the same version(s) of MEncoder, IMO this would be better implemented as an MEncoder option in the GUI/profile e.g. "Use AC3 fixed" (localizable)/mencoder_ac3_fixed. The default value could then be set to true for the Mac build. e.g.

PmsConfiguration.java

Code: Select all

    private static final String KEY_MENCODER_AC3_FIXED = "mencoder_ac3_fixed";

    public boolean isMencoderAc3Fixed() {
        return configuration.getBoolean(KEY_MENCODER_AC3_FIXED, Platform.isMac());
    }


Ideally*, the same should also be done for ffmpeg.

* Well, ideally, ffmpeg and mencoder should just work

Made me chuckle!

Agreed, your suggestion is better and will still set the default correctly (for people scared of the gazillion options that already plagued poor PMS ).

If that's true, we can just detect the version of MEncoder and choose the correct option automatically. We already get the version info so it wouldn't be hard

Although the garbled MEncoder message makes it sound like a fix (and it may well be in buggy MEncoder versions), the ffmpeg documentation indicates that it's a preference with different tradeoffs on different platforms/hardware:

AC-3 audio encoders.

These encoders implement part of ATSC A/52:2010 and ETSI TS 102 366, as well as the undocumented RealAudio 3 (a.k.a. dnet).

The ac3 encoder uses floating-point math, while the ac3_fixed encoder only uses fixed-point integer math. This does not mean that one is always faster, just that one or the other may be better suited to a particular system. The floating-point encoder will generally produce better quality audio for a given bitrate. The ac3_fixed encoder is not the default codec for any of the output formats, so it must be specified explicitly using the option -acodec ac3_fixed in order to use it.

Also: parsing MEncoder versions could get messy. Not all builds report the SVN revision:

Code: Select all

$ mencoder
MEncoder 1.0rc4-4.4.5 (C) 2000-2010 MPlayer Team

I'm a big fan of programs just working with minimal configuration, so IMO it's better to have a bit of code mess to grab the revision/version numbers than to offer users that option.
Of course we can just do both things: try to be automatic but allow the user to override with an option

First i have to say, i love ps3mediacenter and the community seems to be awesome.

@Raptor399: I'm on an iMac mid 2010 with Core i5 3,6 GHz running Mac Os X 10.6.7 with Xcode 3.2.6. I tried your version v1.8 of your build script, but getting an syntax error -> build-pms-osx.sh: line 1291: syntax error: unexpected end of file

Any ideas?

I also tried TARGET_ARCHITECTURE="x86_64"

Any ideas?

Line 1291 would be exactly the last line of the script.
I think the error means that the script expected to find a newline to complete that last line, but there is none.
You can probably solve this by adding a couple of empty lines to the bottom of the script, under the line that reads "build_ps3mediaserver".

Does that help?

My fault. It helped to create the script inside of Xcode and not an external editor Thanks for reply.

Hehe... Glad you found a way out. To be honest I never touched Xcode itself, to me it's just a set of installed binaries that I can use from the shell. I work purely in Terminal and use "vi" to edit. Old unix folks are old.
