This is a (very) bad regression and we should do the same as for x264.

I strongly object to that. It makes the build system slower and harder to maintain for no benefit.

...

Several operating systems don't install pkg-config by default.

Several operating systems don't install a C compiler by default. And most operating systems do not install the development files for the

I am willing to take the burden. libraries by default. What I meant was: On several operating systems, after you install the compiler and the necessary libraries and headers, there is no pkg-config and this configuration was supported by FFmpeg for many years. Removing this support means introducing a regression.

If people need pkg-config, they install it, just as the libraries they want and yasm and texi2html and...

Not everyone who wants to compile FFmpeg can install on the target system.

...

Additionally, I believe it is very useful to link an external library without installing it first.

Please share the basis for that belief.

You misunderstand: When I test, I never install the libraries but always link them from the build directory. (The basis is just my workflow for testing FFmpeg because of user reports that include using external libraries.) -- Ticket URL: <https://trac.ffmpeg.org/ticket/4197#comment:5> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

I am willing to take the burden.

I do not think it can work that way for the build system.

I don't understand: Why should something that does work fine for x264 not work for other libraries?

The extra code complexity is a nuisance for anyone who needs to look at it, and, unlike for an isolated decoder or demuxer, that means potentially any contributor.

I very much doubt this, especially when comparing the "complexity" of our configure script with any other part of FFmpeg.

The slowness, of course, affects everyone.

Could you elaborate?

...

Removing this support means introducing a regression.

The difference between a regression and the cleanup of an obsolete feature become useless is only a matter of point of view.

Of course. I opened this ticket because I consider this issue a (severe) regression.

Not everyone who wants to compile FFmpeg can install on the target system.

Is there a misunderstanding here? pkg-config is required on the build system, never on the target system.

You misunderstand: When I test, I never install the libraries but always link them from the build directory. (The basis is just my workflow for testing FFmpeg because of user reports that include using external

For the sake of clarity, I suggest we keep the discussion about your use

case separate from the discussion about generic users. I do consider myself a user.

Concerning generic users, can you quote actual situations where pkg- config is impossible to install, or at least significantly harder than the other required build components (including yasm)?

I mean every user who is not an admin on the build system. Note that yasm is not needed on all targets.

You certainly will need to invoke exotic cases, cross-building or such, but please keep it realistic.

Please understand while for you (as for many other FFmpeg developers) it is completely clear how to use pkg-config, for me as for many users who post on the user mailing list it is needlessly difficult.

Concerning your personal use case, I am pretty sure that it is possible to alter your work flow just slightly to adjust to a configure that requires pkg-config. You may possibly even save time by doing that.

If I understand you correctly, you need to be able to build ffmpeg with

I want to get rid of it for x264 too! But for x264, it is already there, for speex, it has been removed, and I object it coming back.

...

Of course. I opened this ticket because I consider this issue a (severe) regression.

And I consider it good riddance: configure is faster, simpler, more readable, more reliable.

I don't think it is faster and calling removing a feature being more reliable is hard to understand for me.

Then of course they can install something on the build system: they are installing ffmpeg.

I never install FFmpeg.

Please understand while for you (as for many other FFmpeg developers) it is completely clear how to use pkg-config, for me as for many users who

yasm is not needed on arm and powerpc. post on the user mailing list it is needlessly difficult.

{{{sudo apt-get install pkg-config}}}

This does not even work on my development system and it certainly doesn't work for people using servers where they are not admins. But I meant using pkg-config not installing it.

There is nothing more to do in normal cases. In non-normal cases, the user already did something way more complex than {{{export PKG_CONFIG_PATH=/some/path}}}.

I consider this at least a magnitude more difficult than setting a path.

...

Yes, I just want to be able to build (configure and build) FFmpeg with (most) external libraries without having to use pkg-config.

“without having to use pkg-config” is not a functional need.

It is needed for my workflow and was very often requested by users on the user mailing list. -- Ticket URL: <https://trac.ffmpeg.org/ticket/4197#comment:13> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

how much time is saved by removing non pkg-config cases ?

I must admit, I got carried away. Thinking more specifically about it, the non pkg-config case will only take time if the library was enabled but pkg-config fails. It will only be a burden when auto-detection will be implemented.

Can you or someone else document on the wiki how to setup & use pkg config for the various cases that people need ?

Sure. [http://ffmpeg.org/pipermail/ffmpeg-devel/2014-December/166877.html Patch on the mailing-list.]

One case iam aware of is cross building, or maybe configure could be made to just work in that case without installing wraper scripts or whatever

The most common cases can probably be automated, but I am not familiar enough with cross-compiling to know what the most common cases are. If we can get the linker's search path ({{{ld --verbose | grep SEARCH_DIR}}}), we can set {{{PKG_CONFIG_LIBDIR}}} accordingly, but I do not know if that default search path is usually relevant. -- Ticket URL: <https://trac.ffmpeg.org/ticket/4197#comment:15> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

I see no response to the thread I opened. As such, to me it looks like no one is interested in discussing this, and the change was thus "intentional". Unless someone responds to that thread soon, this ticket should be closed. I will leave it open for a few more days, and in absence of a response will close the ticket.

Why should the users that have reported the issue react on the development mailing list? Why do we (suddenly!) refuse to fix regressions? Why should we handle libspeex different from other external libraries like x264? It is very easy to fix this ticket, I am strongly opposed to closing it just because not all developers use systems without pkg-config or want to force everybody to use it. -- Ticket URL: <https://trac.ffmpeg.org/ticket/4197#comment:25> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

I think what we need to do is make FFmpeg take a clear stance on this issue among some options: 1. We support pkg-config: in this case, we support it all the way, and add all required configure checks. I think very few people like this. I certainly don't. 2. We don't support pkg-config: in this case we remove all pkg-config checks, and add relevant documentation in visible places saying that pkg- config is a build dependency. I personally don't mind this. However, I vaguely recall some legitimate reasons for supporting builds without pkg- config. 3. We support pkg-config with some libraries and not with others: I consider this the most half baked option, but that is what we have currently. In this case, documentation must be in place for describing which external libs can be used without pkg-config, and which ones can't. This is annoying.

We already agreed on having pkg-config as default and detection without

Did not know that. It certainly does not feel that way since many developers are still not happy about this, and comments here and on the mailing list reflect a lack of agreement about this. I will give you the benefit of doubt on this one, and apologize for my negative attitude about this ticket.

In the absence of such proof, one can't call this a regression in my view. Otherwise, theoretically any change in undocumented behavior/state modifications can be called a "regression".

A feature that breaks default detection of a library at least on aix, android, mingw and osx without any discussion or documentation is certainly a regression that cannot be fixed by an entry in the wiki (or

But as said, this is trivial to fix, there should be no further discussion needed. -- Ticket URL: <https://trac.ffmpeg.org/ticket/4197#comment:29> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
