Re: Video build deps for CentOS 6 (Matteo) well, rpmforge is even older than rpmfusion. Rpmfusion is well known, but if vlc is going to be dropped (will it?) we can skip it entirely and reduce the number of packages. Imagemagick is needed to be updated only for mod_imagick, otherwise is not needed. If we limit everything on what is on SD repo (and exclude vlc+mod_imagick) well I think (but must check) that epel is enough and only few stuff must be added (mpg123, lame?, libshout, libmpv2 and maybe nasm). But I need to recheck it since I tried to have everything fs 1.6 needs, with the correct versions. there's one dep on freetype2 is FS which is not really needed, I'll file a pull rq for it, so we can avoid updating it. (you need 2.4.something but with 2.3.11 compiles and works ok) About libpng: I've used the CentOS shipped one and seems to work ok (version 1.2.49) to me. So, I think most of the work is around vlc: you say that does not work well, what will be it's destiny? If is just an experiment I can try to rebuild everything without it and check what is needed again in order to shrink that list (it will be a lot shorter) and report back.

The main "source" of deps (and troubles) is vlc 2.2, which needs a lot of stuff.
I've taken some packages from rpmfusion and rebuilt them, updating when needed.
So while epel is needed for deps, rpmfusion is not because all needed rpmfusion packages have been rebuilt by me using same sources/specs (if not updated)
I don't know if epel will ever accept all packages, because some are also updates to base system, like opencv which is present on CentOS base but too old and ImageMagick, to name few.
So the picture is: if you want to have video under CentOS 6 without hosting something (mainly vlc stuff and it's deps), you're out of luck since FS requirements are on very recent packages.
Just a quick list of stuff needed:
base CentOS updates not present anywhere: ImageMagick (updated), nasm(updated), libvncserver(updated), opencv(updated)
** from rpmfusion: a52dec, faad2, gpac, lame, vlc(updated), libmad, mpg123(updated), x264(updated for vlc 2.2), xvidcore
** from epel (rebuilt because different version) libmpv2(updated), libshout(updated)
** from Freeswitch SD: g722_1, broadvoice, libav, libcodec2, libsilk, libvpx, libyuv(updated), opus, soundtouch, openh264, flite, ilbc (epel has a newer one, pay attention!)
This is the list (should be almost complete, I'm not in the office right now) of what I've rebuit to have video running.
Is possible to reduce by 6 packages if rpmfusion is added with repo. Dunno if is wanted or not.
I think that epel will never accept updates to packages that are already into base distro.
And don't know about vlc and its deps... if rpmfusion exists maybe is because patents does not allow it into epel?
What do you think?

since some packages are only centos 6 specific updates, how do you plan to handle them?
For example, nasm is a required update to CentOS 6 in order to build other stuff, but is not needed for debian or CentOS 7
Right now in the repo I don't see anything distro-specific .

Rpmfusion is well known, but if vlc is going to be dropped (will it?) we can skip it entirely and reduce the number of packages.
It's not getting dropped but it is of limited value, mod_av does nearly everything mod_vlc does, and does it better, the only thing it doesn't do is play youtube videos by youtube url. Seems a minor feature for a massive dependency chain. I'd say just don't bother trying to include it. In regards to mod_av, you only get the functionality people probably want (and same for vlc) if its built against x264, which again, we may have issues finding a package in a reputable repo.
Imagemagick is needed to be updated only for mod_imagick, otherwise is not needed.
mod_imagick supports playing pdf files like videos. Its useful but your call.
If we limit everything on what is on SD repo (and exclude vlc+mod_imagick) well I think (but must check) that epel is enough and only few stuff must be added (mpg123, lame?, libshout, libmpv2 and maybe nasm). But I need to recheck it since I tried to have everything fs 1.6 needs, with the correct versions.
Just to be completely 100% clear, we will not be serving up mp3 or h264 binaries from our repos.
there's one dep on freetype2 is FS which is not really needed, I'll file a pull rq for it, so we can avoid updating it. (you need 2.4.something but with 2.3.11 compiles and works ok)
We for sure need freetype to support a bunch of features that have to do with putting text on video, and it will require rebuilding it against libpng 1.6 for some basic functionality, while these are already optional, this will significantly impact some conference functionality.
About libpng: I've used the CentOS shipped one and seems to work ok (version 1.2.49) to me.
libpng1.6 is required for some transparency functionality that we use heavily. It will build with older versions, but functionality will be significantly diminished.
So, I think most of the work is around vlc: you say that does not work well, what will be it's destiny?
We are not getting rid of it, but my recommendation would be to not try to build it. I already spend significant time telling people to use mod_av instead.
If is just an experiment I can try to rebuild everything without it and check what is needed again in order to shrink that list (it will be a lot shorter) and report back.
I'm not sure about mod_imagick, not tested it yet.
Another question about mp3 code: what about mpg123/lame that is needed by FS?
These can't go into our repo, but any moderately recent one should be fine. I think the api is stable. The issue with using older versions would be if it will cause stability issues and crashing, as there has been a long list of buffer overflow issues in that code over the years.
If you're not willing to add it to your repo, how mp3 files are handled ? using libav ?
If there is no other place to get packages for that library, the module simply wouldn't be built, and that feature would not be available.
If yes, another dep can be removed.

Uhm, while I get more informations, I get more confused :) Or, at least, seems to be that is not possible to have a 100% working install on CentOS 6. Both rpmforge and rpmfusion has mpg123 and lame, so mp3 functions can be kept. Dropping mp3 support is just not feasible imho, since is a heavily used format. If rpmfusion is not very trusted (nothing for el7 yet) there's handbrake repo which is heavily focused on video ( http://negativo17.org/repos/HandBrake/ ) and has (updated) x264 stuff. x264 stuff on rpmforge is just too old. ( handbrake is a really powerful video transcoder, so for me can be trusted :) ) Combining both we may have a full mp3/h264 support. What do you think? libpng 1.6 and freetype2 compiled against it is a different story. Even CentOS 7 does not have libpng 1.6. And since is a quite "basic" lib I think is not sane to try to update it. How do you handle them in jessie ? With two separate packages that do not overlap with system one and pointing FS build to it? (I see that also jessie has libpng12 and freetype linked against it) So, to sum up, right now I see this: * include 2 new repos: rpmforge and handbrake for mp3+h264 . The question is if both are trusted enough. Of course testing is needed. * try to build a separate freetype2+libpng16 and out that into SD repo for CentOS * regarding mod_imagick, I'm still testing the situation, while I've already updated ImageMagick for fax conversion purposes since months without issues in production, I need to check it better with the new Fs module. What do you think? regards, Matteo PS: just for curiosity, why you do not want to host mp3 and h264 code? You already host openh264, is not the same issue? ----- Il 25-giu-15, alle 22:23, Michael Jerris mike@jerris.com ha scritto:

** from epel (rebuilt because different version) libmpv2(updated), libshout(updated)
** from Freeswitch SD: g722_1, broadvoice, libav, libcodec2, libsilk, libvpx, libyuv(updated), opus, soundtouch, openh264, flite, ilbc (epel has a newer one, pay attention!)
This is the list (should be almost complete, I'm not in the office right now) of what I've rebuit to have video running.
Is possible to reduce by 6 packages if rpmfusion is added with repo. Dunno if is wanted or not.
I think that epel will never accept updates to packages that are already into base distro.
And don't know about vlc and its deps... if rpmfusion exists maybe is because patents does not allow it into epel?
What do you think?

for things like nasm, is that newer version out there for example in epel? that would be the best case. Backup would be to take a source pacakge from something newer and just rebuild in a way that doesn't require any modifications, fallback we can put the src out on our download servers and create a job for it. As for x264, we will not be putting that in our repo, you'll have to find some way to get that into some official repo that we can reference, maybe see if you can get it into epel? The best case would be to get as much as possible directly into epel so it leaves us having to manage as little as possible.

I know how specs works, I'm maintaining a private repo like epel with tens of packages since years, using the same tools used by fedora ( koji, mock, mash).
My intent is not to create a custom build of freeswitch, but a repo like epel or rpmfusion with only the needed build deps.
What is not clear to me is the flow to add a new dep.
Let's say I need to add a bunch of new libs, like gpac, nasm, x264, to name a few.
Which is the correct approach to fit into Fs build structure?

You know in the spec files you can if things for specific versions... You'll just have to figure out the correct Ifs for Cent7 vs Cent6 vs say Suse

Ok,
since some packages are only centos 6 specific updates, how do you plan to handle them?
For example, nasm is a required update to CentOS 6 in order to build other stuff, but is not needed for debian or CentOS 7
Right now in the repo I don't see anything distro-specific .
