[ITP] ffmpeg (5.1.2)

[ITP] ffmpeg (5.1.2)

[Takashi Yano]

I would like to propose new package ffmpeg which is
well known audio/video tool. ffmpeg is ported to
many linux distributions and other unix like systems
as well as widows. Since there is windows build,
the demand of cygwin port might be relatively small,
however its libraries are usefull for other softwares.

I have posted another ITP for MOC (Music On Console)
which is a ncurses based music player, whose plugin
uses ffmpeg libraries.

I have already prepared the ffmpeg package as follows.

https://tyan0.yr32.net/cygwin/x86_64/release/ffmpeg/

To build ffmpeg, other new packages i.e., x264, x265 and
xvidcore are required, I have proposed ITP at the same
time.

It's also missing cygswscale-6.dll which I don't find anywhere.

It should be in:

https://tyan0.yr32.net/cygwin/x86_64/release/ffmpeg/libffmpeg/libffmpeg-5.1.2-1.tar.xz

which is reuqired by ffmpeg-5.1.2-1.tar.xz.

OK, I had overlooked that in the ffmpeg folder.
Now I get:

Thanks for testing.

You need libSDL2_2.0_0 package installed as described in
https://tyan0.yr32.net/cygwin/x86_64/release/ffmpeg/ffmpeg-5.1.2-1.hint

Thanks!

For a long time, ffmpeg was not included in Fedora, due to concerns 
about codec patents, but those issues seem to have been resolved.

Can you please investigate what configuration is used in Fedora, and 
what the effects of matching that would be?

A first test suggests that this build may be significantly (~70%) slower 
than the native Windows build of ffmpeg, unfortunately. Do you see a 
possible reason for that and a chance to compensate?

As well as looking at:

	https://src.fedoraproject.org/rpms/ffmpeg/tree/

I've found it useful to look at other work done in recent forks e.g.

https://src.fedoraproject.org/fork/yselkowitz/rpms/ffmpeg/commits/rawhide

and other distros; OpenSuSE and Arch are like Fedora; Gentoo is like Cygwin; 
OpenBSD is behind on v4 so skipped:

I tested the encoding speed of ffmpeg and the cygwin build indeed
slower than windows build. In my test, the speed is almos half.

However, I noticed that if "-threads 64" option is added, it gets
faster. Even with this option, cygwin build is 15% slower.

I am not sure why...

I have checked the configuration of ffmpeg in fedora.
It seems that most of codecs are disabled in fedora
by default unless 'all_codecs' flag is specified.
https://src.fedoraproject.org/rpms/ffmpeg/blob/f37/f/ffmpeg.spec

I have built a ffmpeg package using the configuration
almost imitated fedora.
https://tyan0.yr32.net/cygwin/x86_64/release/ffmpeg-free/

You would find this ffmpeg of the above configuration is
almost unuseful...
aac, h264, hevc, mpeg4, wma, wmv, etc. are not supported.

I also imitated the configuration with 'all_codecs' flag
and have built another ffmpeg package.
https://tyan0.yr32.net/cygwin/x86_64/release/ffmpeg-all_codecs/

This is almost common with the major ports of ffmpeg.

Could you please review them?

Thanks for looking into this.  The packaging looks fine from a technical 
standpoint.

The concern here is that we have an informal policy to only accept 
packages which is would be allowed in Fedora (by it's policies on 
content and being free of legal encumbrances (e.g. license, patent and 
trademark issues))

After some discussions, it seems that policy should be formal.  I've 
amended [1] to state that.


I'm sorry to cause you more trouble, but given that, can you package 
this based on the codec set in Fedora's ffmpeg-free?


If you don't think the package is useful under those constraints, don't 
let this discourage you from offering either the cygport for interested 
people to build it themselves, or the packages via an overlay package 
server [2]

[1] https://cygwin.com/packaging-contributors-guide.html#submitting
[2] https://cygwin.com/package-server.html#overlay

(Note for the peanut gallery: none of this should be construed as 
reflecting my personal opinions on the virtues and validity of software 
patents generally, or in this specific case.  This is not the place for 
discussion of such issues)

Thank you for your consideration. I have re-arranged the ffmpeg
package basend on Fedora's ffmpeg-free package.

https://tyan0.yr32.net/cygwin/x86_64/release/ffmpeg/

As I mentioned in IRC, the Fedora approved numerous of codecs for
ffmpeg recently. As a result, ffmpeg-free package becomes much more
useful compared to the past.

As far as using for ffmpeg-plugin of moc (Music player), it has
almost enough codecs.

ffmpeg itself might be somewhat weak (e.g., no x264, x265),
however, it whold be much better than nothing.

This seems an odd way to write this. If possible, just apply the patch 
unconditionally (I assume it doesn't break all_codec=no builds), and 
treat it normally (i.e. keep it next to the cygport, list it in 
PATCH_URI, so it gets placed into the source package.)

If it's really necessary to only apply the patch in the all_codec=yes 
case, use src_patch_apply_hook [1].

[1] 
https://cygwin.github.io/cygport/src_prep_cygpart.html#src_patch_apply_hook

Otherwise, looks good.

Patching conditionally is necessary because the target file
is excluded from free-source tarball (ffmpeg_free_sources)
if all_codecs != "yes".

I revised the cygport file which uses src_patch_apply_hook()
as you recommended.
