new packages: shotcut, mlt and their deps

[knyipab]

Draft PR. currently the app mostly works well but cannot output video results, perhaps there are problems with QProcess, see #20354 . [fixed]

Other things to note:

• [fixed] 32-bit arch does not build (see error log, related to qint64 type)
• [fixed] GPU mode requires PR new package: movit #20352 , related to [Help] Cross compile movit (shotcut & mlt GPU deps), which can build on-device #20351
• [optional] rtaudio (mlt optional deps) needs ALSA and jack API, we may need a functioning pipewire, related to [Bug]: pipewire seems not tested and it is not working #20316
• [optional: someone may try] opencv cannot be included as mltbuild deps (which is done by Archlinux), prompting some compilation error related to QPrivate when building shotcut

[knyipab]

This package will be ready and I will force-push it once #20352 and #20374 are merged.
The sound effects should work with sdl2 package. jack-dummy is more for runtime purpose (won't produce sound) otherwise need to patch the code. rtaudio is a longer run TODO item when pipewire is in a good state. opencv is nice-to-have item if someone find a fix but that shouldn't matter much.

Please make sure to add

termux_step_pre_configure(){
	CXXFLAGS+=' -Wno-c++11-narrowing'
}

to make sure the 32 bit builds succeed.

[knyipab]

Thanks and will do when movit is available

[TomJo2000]

In that case I'm gonna go ahead and merge movit.

[knyipab]

Tested on my aarch64 phone. Import playlist, track editor, preview, some basic filters (rotate, opacity), export work.

Ready to be merged. See if you are fine with the way I patch the source code.

[truboxl]

Please change all the .patch files that hardcoded with /data/data/com.termux/files/usr to @TERMUX_PREFIX@

[knyipab]

fixed. thanks

[Biswa96]

x11-packages/mlt/0001-cmake-mlt-undefined-version.patch and x11-packages/mlt/0002-cmake-mlt++-undefined-version.patch are probably not required. The issue can be fixed with LDFLAGS+=" -Wl,--undefined-version" (see packages/zlib/build.sh).

[knyipab]

Thanks @Biswa96 . You are right and force-pushed.

[truboxl]

Please change TERMUX_PKG_MAINTAINER field

[knyipab]

oh right, fixed.

[knyipab]

@truboxl refactored: addressed your comments, used the jack merged in #20544, removed TODO, and removed the libjack.so.0 patch.

[knyipab]

Just realized that this PR should be ready but has not yet merged. Any chance merging to provide shotcut to Termux users? And then close #20021

[TomJo2000]

LGTM.
Gonna wait for the CI to run through before merging.

fixes #20021

[TomJo2000]

I went in and updated the build scripts.

I had to regenerate mlt/0004-fhs-path.patch, but that was just some line drift causing the 7.24.0 version of the patch to no longer apply.

[TomJo2000]

Guess that's what I get for only testing against AArch64 locally.
We're having symbol issues with 32Bit again.

Related to mltframework/shotcut#1580 and mltframework/mlt#1020.
TLDR: Someone suggested below patch and mlt dev said that only apply it conditionally for 32-bit build:

--- a/src/mlt++/mlt++.vers
+++ b/src/mlt++/mlt++.vers
@@ -541,6 +541,7 @@ MLTPP_6.14.0 {
       "Mlt::Playlist::reorder(int const*)";
       "Mlt::Transition::connect(Mlt::Service&, int, int)";
       "Mlt::Producer::set_creation_time(long)";
+      "Mlt::Producer::set_creation_time(long long)";
       "Mlt::Producer::get_creation_time()";
   };
 } MLTPP_6.10.0;

Honestly, I am not so sure how to make a conditional patch other than writing some sed shell script. Help is appreciated. Thanks.

[TomJo2000]

Should be easy enough.
I'll do it in a bit.

[TomJo2000]

util-linux has an example of a bit-ness depedent configure argument.

termux-packages/packages/util-linux/build.sh

Lines 61 to 63 in 31e2ed4

	elif [ $TERMUX_ARCH_BITS = 32 ]; then
	TERMUX_PKG_EXTRA_CONFIGURE_ARGS+=" --disable-year2038"
	fi

We can use the same approach and just apply a *.diff patch instead.

[knyipab]

EDITED:

Can't build even reverting to your version. Clueless and shouldn't relates to libicu cuz there was no update.

Previous incorrect comments.

There seems to be a bug in the build system handling qt6 cross tool. Can't build even reverting to your version.

Not many clues, I guess related to gst-plugins-gl-headers being installed during the build process for unknown reason and breaks other packages (it conflicts with mesa). Cuz I encountered weird problem recently in TUR's on device building.

[truboxl]

The cross tools need to be rebuilt after the Ubuntu base image upgraded to 24.04.

[knyipab]

Thanks a lot! Ready to be merged.

[TomJo2000]

LGTM.
Thanks a lot for your contribution and working with us on it.
