Latest Mac OS X beta build

[Horseylicious]

That won't be necessary. I think I found the solution for the distorted and skewed audio!
See the Compiling PS3 Media Server on OSX thread for more info.

Wow! Good work, Raptor399. Thanks for your persistence. Sounds like it might fix sync issues with ISO files and VIDEO_TS folders as well.
Can we expect a build soon? If you update the script I might even be tempted to give compiling it myself a go:-)

Awesome work Raptor399! Any chance of sharing your build?

No, sorry!
I'm not going to share my build for a couple of reasons:

- I am not sure my fix is the right fix. Yes, it works for the files I tested it with, but I really have no clue at all what the impact is of changing the audio codec from "ac3" to "ac3_fixed" on mencoder. For all I know it might very well break other stuff.
- I am not sure my patches are the right patches. Even if they are correct for OSX, are they correct for Windows and Linux as well?
- I want to push for an official PMS (release candidate) for OSX by the devs. Which is way overdue!
- <soapbox>In this day and age you should be distrustful of random untrusted people (like me) putting up binaries for download and executing those on your computer. That is why I shared the script with which full builds can be compiled.</soapbox>

Patience! I am pretty sure the devs will pick up on this.

Raptor:

used your script to build 2 days ago, followed the instructions in the other thread, including the ac3_fixed "patch"

DTS and AC3 audio streams work just fine however AAC streams do not. They sound...."choppy"

Ah, thank you for sharing the results!
Was AAC choppy without the patch as well (just replace "ac3_fixed" with "ac3" everywhere in the code)?

I'll have to rebuild without the patch and i'll let you know

Edit: Yes, AAC audio is still choppy, rather sounds like its been time stretched, even without the patch.

The old 1.20 mac build does not suffer from this.

Well, that is partially good news then. It means the "ac3_fixed" change is still a valid one and is (in itself) not the cause of the AAC problems.
Judging by the postings on other boards there are still many problems with current builds of mencoder, also on Windows and Linux.
On those platforms they use 4 separate versions of mencoder ("mencoder", "mencoder_mt", "mencoder-alternative" and "mencoder-alternative_mt") to combat incompatibility problems. We could follow suit on OSX and compile 4 versions as well (instead of 2 now).
I haven't been able to get older versions compiling though, I'll give it another shot.

Bah!

The Windows build is using revision 32674 of MPlayer for "mencoder-alternate", so I tried checking out and building that. Note that this revision of MPlayer automatically checks out a version of FFmpeg as well, as opposed to more recent MPlayer revisions.

At first compiling did not work at all, until I realized that you have to configure, build and install the older version of FFmpeg first because of dependencies on header files. (Running the script builds and installs a newer and incompatible version of the FFmpeg header files in the $TARGET/include directory)

But even with that fixed, I end up with an error:

Code: Select all

libmpcodecs/vd_mpng.c: In function 'pngReadFN':
libmpcodecs/vd_mpng.c:77: error: dereferencing pointer to incomplete type
libmpcodecs/vd_mpng.c: In function 'decode':
libmpcodecs/vd_mpng.c:114: error: dereferencing pointer to incomplete type
libmpcodecs/vd_mpng.c:131: error: dereferencing pointer to incomplete type
make: *** [libmpcodecs/vd_mpng.o] Error 1
make: *** Waiting for unfinished jobs....


Looks like a dead end there. Well, for me at least.
My C is too crappy to understand the error, plus I don't really want to fix anything in the source to obtain a pure build.

For people that want to replay what I did and experiment a little, here is what I added to the script to attempt the build:

Any more word on the chances of an official build coming?

I'd also really like to know when I can get my hands on the next build
