VLC: implement building from source again, build with X11 for older OS (?)

[barracuda156]

1. Desired enhancement: restore building VLC3 from source, which was removed in [ddd6f4336c9cb206f76bc438e355a929425676b0/macports-ports]

2. It seems that Qt can be disabled altogether for VLC, and then there is nothing to prevent it from building in principle even on Tiger. Even with no GUI it should be perfectly usable, as long as the output is sent to X window.

If the point 1 is too complicated to implement, maybe we can make vlc-cli port?

You can try, but you'll probably run into the reasons why I got fed up with building from source in a "MacPorts condoned fashion".

I have VLC2 building now on PowerPC, but I did not try VLC3 in any form.

[barracuda156]

Apparently support for Qt4 existed early in 3.x branch: ​https://github.com/videolan/vlc/commit/1c221a77d92935866e897254c07e1d12a4b95ae0

Though it could be a clean-up too. But if it still worked at the time of 3.0.0-1, it is likely restorable into a bit later version.

By the way, are you okay if I modify VLC2 port substantially? Or should I keep changes to the minimum?

It is broken now, and if no one intends to use it for current macOS versions, I rather rewrite the thing to make it easily maintainable for systems without Qt5. Essentially, drop the stuff that does not work, use Qt4 and X11, remove libvlc2 subport etc.

Alternatively, I can make VLC2-X11, for example, or however we call it, to implement support for older OS.

(This only applies to VLC2; VLC3, if restored, should target new macOS.)

[RJVB (René Bertin)]

I cannot recall having tried Qt4 anytime since I started working on the port but the Qt5 interface never worked properly because it does things that Qt5 doesn't support on Mac. If memory serves me well, creating timers and/or an event loop that is not on the main thread. That's a design quirk that will undoubtedly be very hard to change.

If you take maintainership you can do what you like, and I have my own version in my MacStrop tree anyway. I'd appreciate if you kept the libVLC subport just in case anyone picks up/creates a port that (would) depend on it. If you can figure out a way to build only that part you could even let the main port depend on it (rather than conflict with it like now) without having to rebuild everything.

It is broken now

I haven't rebuilt it in a while but I'm guessing that means broken either on (much) newer OS versions than my 10.9 or on older ones?

(This only applies to VLC2; VLC3, if restored, should target new macOS.)

Reminder: upstream didn't like the idea of having a "non-official" build in MacPorts back when the subject came up in a ticket I created.

[barracuda156]

Actually did not take much, I have VLC 3.0.20 built on PowerPC.

Need to figure out how to set Pulse Audio correctly, otherwise it spits out vlcpulse audio output error: PulseAudio server connection failure: Connection refused, but video works. Given that, audio should be fixable.

Obviously, with X11 backend – I won't bother trying to restore Qt4 GUI, it is not really essential. Once I get audio working and sort out patches, I can make VLC-x11 port.

[RJVB (René Bertin)]

FWIW, back when I did my 64bit wxGTk build of Audacity it happily used CoreAudio (through PortAudio). PortAudio is a dependency of my Linux port for VLC3 so you should be able to use it on Mac too, and thus (hopefully) get access to direct audio playback rather than through PulseAudio.

Hmm, how do you make it work with it? Configure does not seem to have such an option anymore.

And CoreAudio, I think, upstream has deliberately broken. Won’t be hard to keep stuff working, given it works fine with other software, but instead they do this: ​https://github.com/videolan/vlc/commit/ad17fde5c6753e5ed1b13087db62e3b92561227e

[RJVB (René Bertin)]

You're right, apparently we found a dangling/obsolete dependency in my port. Bummer.

Upstream don't support legacy OS X versions, so it makes sense that they remove unnecessary code. Shouldn't be hard to reintroduce though, from the looks of it.

If not ... how about JACK? If memory serves me well (rare these days ;)) my PPC Macs were the only systems where I used that stuff with some form of success. PulseAudio can work, but it can also introduce noticeable lag. (On Linux it typically runs under some form of realtime control.)

[RJVB (René Bertin)]

Or ... have you looked at all at PipeWire? It's touted as the replacement/alternative to PA solving all (kinds of) woes, and there's this: ​https://www.remlab.net/vlc-plugin-pipewire/

Jack is/was broken on 32-bit archs due to a bug in upstream GCC, which led to ICE during compilation. It might have been fixed in the latest snapshot of GCC in fact. I will try building it (since I have just yesterday built my gcc-powerpc from the new snapshot of GCC 13).

I have seen that error with pulseaudio on Sonoma by the way, with a different port. Do you know how to make in work on macOS/in Macports? It could be I just do not add needed environment settings or smth alike.

Isn't pipewire Linux-only? I thought it relied on some Linux system libs which do not exist in macOS. Like alsa. (This is from memory, I can be wrong.)

16. S. So silly they dropped portaudio, which is the most reliable of all these.

I just remember that it's tricky enough that at some point I created a hacked version of the port that renames the binary to prevent it from getting auto-started (and for the rest just serve to fulfill dependencies, but as usual, if I did make any notes about it they've since been removed).

I didn't have it down as Linux-specific though their homepage does say "for Linux"; the build system also seems to support (some) *BSD versions. Those *might* have ALSA, though that library is not a required dependency though. There are too many dependencies and the install instructions mute about that, so I can't easily say what PipeWire will fall back on in case ALSA is missing. I wonder if no one ever wrote a bridge from ALSA to CoreAudio?

(And VLC dropped PortAudio because it was buggy and unreliable. Really not illogical when you have a native implementation, esp. since older PA versions couldn't really copy with dis/appearing sound devices without restarting the application.) IMHO the best solution would be to get the existing VLC CoreAudio backend to build. That's probably mostly a 1-time effort, and hopefully almost exclusively a question of reintroducing code that was stripped. CoreAudio hasn't evolved much after all.

I recently built a couple of projects using GCC 12 where I ended up setting OBJCXX to (a recent enough) clang. For other reasons (@autorelease and family) but it may be your solution too. If that works here you can let the Portfile pick the most recent known-compatible clang version the user already has installed or else pull in a version of your choice. (I do that with Python build dependencies nowadays.)

[barracuda156]

With almost the same patches (I had to drop a patch for freetype, otherwise it did not build) on Sonoma I got a nearly identical result: video works, audio is broken. So at least it is not specific to powerpc. Either some patch is wrong, or pulseaudio is broken, or VLC is broken without GUI. Hopefully the first :)

I tired playing some FLAC on Sonoma:

And have no audio output at all.

[barracuda156]

On PowerPC pulseaudio just segfaults on start, so no surprise it failed with VLC. Should be fixable. Sonoma still makes me wonder though.

Segfault on ppc fixed, and I have found something very funny which perhaps explains why it does not work: the port installs dylibs, but its binaries are looking for .so objects:

That looks like a not uncommon build system bug where modules/plugins are built as shared libraries (which they are... more or less) but the build system thinks that means they need to have a .dylib extension. There are several ways to fix that, but beware that some projects actually do use modules as shared libraries, usually for unit-testing. And that won't work when you build them as modules because Darwin does generate slightly different file types for that. The easiest solution would be to install symlinks or rename the files in the post-destroot.

I honestly can't remember if I ever ran into this issue on Mac, but I do know that pulseaudio worked (for some people) at some time.

You can use paplay from port:pulseaudio itself for basic testing, and port:pavucontrol for more advanced tinkering. That port was updated quite recently so someone must have tested pulseaudio...

The X11 shared memory errors are common and frequent, due to the fact that shared memory limits are quite low by default on Mac. I have started getting them after a GTk3 update, leading to apps being aborted until I wrote an X11 error handler that ignores certain errors. I figured out how to avoid the allocation failure by increasing the right limits but then got 2 KPs in a row while testing an update to webkit2-gtk and decided I could live with the errors that are mostly without consequence. (That might be different for video playback).

Obvious/stupid question: did you verify if PA needs to load a dedicated module for supporting CoreAudio? I'm on my Linux system ATM, and see 3 modules for ALSA, and 2 for OSS:

  /opt/local/lib/pulseaudio/modules/libalsa-util.so
  /opt/local/lib/pulseaudio/modules/module-alsa-card.so
  /opt/local/lib/pulseaudio/modules/module-alsa-sink.so
  /opt/local/lib/pulseaudio/modules/module-alsa-source.so
  /opt/local/lib/pulseaudio/modules/liboss-util.so

Wait, there's no more CoreAudio support in PulseAudio? From what I see in the HB recipe they only make CoreAudio the built-in default.

Logical, pavucontrol sees what pulseaudio provides...

There's no port for that, or is there? I'm not aware whether it works on Mac. I know I mentioned it but that was just to show that PulseAudio has modules for the different sound backends. However, getting hiss is a first step to getting something a bit more meaningful.

You must have understood how well it worked... Thing is I can't even remember why I even tried this, but it must have been before I found out about libVLC and the VLC backend to phonon that works just fine to get sound in KDE applications.

Ah yes, I remember running into code that required those changes to build. Honestly, I wouldn't bother backporting, I'd first try a PulseAudio version from before that patch above.

16. S. By the way, how do I check pulseaudio on its own, without VLC?

As I said, paplay.

Do you have a VLC2.x version that makes sound through CoreAudio on your legacy systems? If so I'd try to get the CoreAudio "driver" to build and work with VLC3.

Does not work on either systems, though fails a bit differently.

That is not trivial, unfortunately, since the code in libauhal depends on general VLC headers (like vlc_es.h) and just replacing with VLC2 versions does not work. So now the question is whether it is easier to fix the current code and restore the older but working one (which would require modifying stuff beyond CoreAudio plugin).

[barracuda156]

Ah, this was the error with the VLC3 libauhal:

audio_output/auhal.c:450:27: error: 'kAudioObjectPropertyScopeOutput' undeclared (first use in this function); did you mean 'kAudioDevicePropertyScopeOutput'?
  450 |                           kAudioObjectPropertyScopeOutput);
      |                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

(and more of the same). It also uses AudioFormatID which is 10.10+: ​https://developer.apple.com/documentation/coreaudiotypes/audioformatid

Which led to to a choice of disabling it in a hope PulseAudio will save us. Well, PulseAudio is broken and god knows which is broken worse :)

You mentioned a SIGSEGV in pulseaudio?

The one I referred to is specific either to powerpc or at least to < 10.7. Something which is supposed to work in libpthreads is in fact pretty broken. I have seen that failure elsewhere, though I am not entirely sure whether it is just broken or fails to work in some conditions but not generally.

I just got one when letting it launch as a daemon. In that case it tries to do something you're not allowed to do after a fork() on OS X (but I don't know since what version).

Later versions perhaps use poll, and that will not work correctly.

From your log it follows you use rather old version of it. I did not try it. Was it built from a custom portfile or standard, just archaic one?

From your log it follows you use rather old version of it.

Yes, but should be new enough. (I do use a newer version on Linux.)

Was it built from a custom portfile or standard, just archaic one?

Thank you.

If you have a few min, could you try the current version on your system? I just wanna make sure it is not broken just for me (which is possible if I do something wrong).

It thinks gcc13 does not support gnu11 :)

You do mean the current mainstream version then? I can try, but not promise when. Why don't you ask on one of the mailing lists, or file a ticket? After all my system isn't really relevant for what you're doing.

Not exactly. GCC is very good at backward compatibility with older OS versions, but not so much with older build systems. You could try to figure out where the earlier _DARWIN_C_SOURCE definition comes from, but redefining a token is in no way an error in C (AFAIK!) so at least the -Werror argument would have to be dropped from CFLAGS during these tests.

FWIW, I think I had a renewed interest in PulseAudio a few years back to see if it would allow me to have remote sound when working over a VNC connection. I never managed to get that to work, possibly because I don't feel like running Avahi in addition to Apple's own ZeroConf/Bonjour (see the zeroconf init error in the terminal output I copied).

I have found something potentially interesting, though old: ​https://github.com/zonque/PulseAudioOSX

Looks like something written "around" PulseAudio. The prefpane and helper might be interesting, if they don't require the HAL plugin (of which I fail to see the interest).

Did that. Something appears to be wrong with the CoreAudio modules: they fail to initialise, and PulseAudio quits because it doesn't detect any sound hardware as a result.

The dylib-instead-of-so thing is because of the move to Meson, easy enough to fix in modules/meson.build but you the etc/pulse/* config files (that should be installed as samples, not overwrite the current versions!) need to be fixed too. (Plus evidently meson doesn't use the same weird versioning as libtool/autoconf so you end up with libraries with a lower compatibility version and are rejected by all dependents...)

EDIT: I see that the CoreAudio code hasn't changed between the PA version in my tree and the current version (17), except for an additional headerfile that doesn't appear to be used. The reason module initialisation fails (or is thought to fail) could thus be trivial...

FYI, I have pushed a full upgrade to 17.0 at ​https://github.com/RJVB/macstrop/tree/master/audio/pulseaudio (URL fixed).

Darwin/Linux so there's some crud to filter out, but: it works. Heck, even publishing over Apple "Bonjour" works; I've been able to stream audio from my Linux rig. Sadly there's no implementation for the opposite direction, but then I have almost no PA clients on Mac anyway.

Switching to .so on macOS is wild LOL

Let me try. Great, if it gonna work finally.

I guess I miss something. With paplay I keep getting this:

Connection failure: Connection refused
pa_context_connect() failed: Connection refused

With pulseaudio I just get a bunch of complaints on trying to launch it:

So it looks like I am back to this: ​https://trac.macports.org/ticket/69539#comment:21 With fixed modules, but broken CoreAudio.

[RJVB (René Bertin)]

I'll try to remember to upload my /opt/local/etc/pulse/default.pa file when I get back to my Mac. There may be something wrong in the one that gets installed by default, I haven't tested that. The simplest explanation would be that it checks for the existence of modules with a .dylib extension.

I also got the "any sound hardware" error the 1st time I tried and I wouldn't be surprised if that's because of looking for modules with the wrong extension. But you should be able to test that with pactl load-module module-coreaudio-detect and pactl load-module module-coreaudio-device.

The system bus messages come from the fact that you're not running a system dbus daemon. I think you can ignore them safely.

[RJVB (René Bertin)]

The default.pa file I promised.

[RJVB (René Bertin)]

BTW, my renaming of the daemon to pulseaudio.daemon is in no way responsible for the fact it works; I just began doing that at some point so it wouldn't be auto-started.

I do install it setuid root so I can start it with --realtime but I'm not convinced that it actually has Mach realtime support and it shouldn't need to run with escalated privileges just in order to detect sound hardware, of course.

Not really. The linker won't find libfoo.so from -lfoo of course, but it will accept the file just the same (the actual libraries in frameworks don't even have an extension at all).

But there's no standard for the extension of shared modules/plugins and as I said before, those can be created in a way that you can't use them as shared libraries even if they otherwise behave the same way.
