Hi, new here and first post 
Finding out about score made me really happy, because it is exactly what I was looking for.
The problem is that I can not get it to work properly at all on my mac. I suppose it might be an issue with my system as Natron, for example, is also not really performant. I downloaded the demo of a proprietary tool âMagic Music Visualsâ which works fine though.
So I am turning to this forum to find out if anyone has ideas to make this work on my system or if anyone has similar issues. There must be a bottleneck somewhere.
Thanks in advance for any ideas.
Hi !
Would you be able to share some scores that donât work fast enough for you, so that we can see where the bottlenecks are on macOS ?
Thanks for the reply. It really is basic things that do not work. Video Playback for example, is stuttery, even after conversion to HAP. All I do is create a window device, and drag the video into the timeline and it stutters. Same with ifs process etc. Anything video. I am not sure why. Thats why I need some help isolating. Is it my macOS version? Is it my graphics card? Do I have a general issue with FFMPG? I hoped for some wisdom of anyone else, who already had to troubleshoot ossia score.
On a more personal note: I really want to get into ossia. Score is looking like the foss creative environment of my dreams (for fun, not for business). Only my time is limited, but I am willing to pay in minutes and hours.
Okay, thatâs definitely not normal. On my mac (macmini 2018 with intel iGPU) just putting a video does not stutter, especially not if itâs HAP, and I can easily put video filters after it before the framerate drops.
Are you running a M1 or an Intel mac ? Do you have a retina screen, and if so, which screen resolution / scaling setting are you using ?

It is a good old intel machine, I already posted the threads over at github issue #1396 but paste them again plus GPU info below. I checked out from github (with submodules) and tried building score so that I can attach a debugger, but I need to get my dependencies straight (used the osx-brew.build.sh)

Okay, very much not normal then, as this is quite more powerful than the macmini I test withâŚ
For building on a mac you need:
- Latest XCode (update if youâre not sure)
- Inside the source dir:
brew update
brew upgrade
brew install ninja qt boost cmake ffmpeg portaudio jack fftw sdl lv2 lilv suil freetype
mkdir build
cd build
cmake .. \
-GNinja \
-DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DCMAKE_INSTALL_PREFIX=install \
-DSCORE_DYNAMIC_PLUGINS=1 \
-DCMAKE_UNITY_BUILD=1
cmake --build .
cmake --build . --target install
then you should be able to see where time is taken through Xcodeâs Instruments:

Thanks, will give it a try. Forgot one important detail. I can not go to the latest xcode version because I am still on macOS 11.6.2 for reasons. Could that be the issue? What are you using on your test machine?
Edit build is failing:
FAILED: 3rdparty/libossia/src/CMakeFiles/ossia.dir/Unity/unity_0_cxx.cxx.o
Looking into it now, but help appreciated.
On 11.6 you should have not the last version but close enough that it will work (some plug-ins will be disabled ; for what you want it should be fine though).
Can you try to post the whole log ? Also I spent some time fixing stuff with brewâs Qt version this morning so you may need to pull the repo again:
cd score
git pull
git submodule update --init --recursive
(and in the meantime if you could send me e.g. a video file youâve tried and the FPS youâre getting + screen resolution / scaling factor, it would be great ! also you mentioned FFMPEG but itâs most likely not it, we only use it for decoding (and even then, decoding HAP is mostly done with a special codepath that goes through the GPU for maximum performance))

For reference I tried a simple score with a 1080p video followed by two ISF effects:
it takes between 10% and 20% cpu here, and seems to run at 60fps ; most of the CPU is taken by the UI redraw ; the video pipeline does not even show up when profiling.
It would be interesting to see what Instruments give you in the same case. I used an HAP sample from Vidvox.

Thanks for the instructions. Trying to continue on this as soon as possible. Got corona right now, so taking it slow 
Thanks.
It might be an issue with my qt5 version or my path but I am too unexprienced to find it. I made sure to upgrage both, qt and qt5 via brew. Here is the result of cmake --build . >> output.txt from my second build attempt after deleting score checkout and starting from scratch.

Hi @jcelerier where you able to spot why my build is not working?
Hi ! sorry, I was at a conference until now.
The qt and qt5 packages cannot coexist on homebrew (mainly because it puts them both in /usr/local/include/ so you get a mix of files from both versions which does not work at all).
If you can, just use the qt5 package and remove the qt(6) one

That worked! Thanks a million.
I did brew uninstall qt and brew uninstall qt5 followed by:
brew install qt@5
echo 'export PATH="/usr/local/opt/qt@5/bin:$PATH"' >> ~/.zshrc
export LDFLAGS="-L/usr/local/opt/qt@5/lib"
export CPPFLAGS="-I/usr/local/opt/qt@5/include"
export PKG_CONFIG_PATH="/usr/local/opt/qt@5/lib/pkgconfig"
As suggested by brew to make sure the proper version is picked upon compilation.
Maybe you might consider to replace âbrew install qtâ with âbrew install qt@5â in the scripts, at least as long as qt6 is not yet supported?
And one more question: Should --target install have created an app bundle or do I need to create that myself? Thanks again for your patience, really appreciate to be guided through this process.
great

yes, definitely (technically, it builds with qt6 but there are a couple unfixed issues).

hmmmm with these build flags I donât think so - they are optimized for local development so you should just have an ossia-score binary in the build folder, which should be enough to check the performance issues (as now you have a build with debug symbols which will be able to tell us where things are slow)

e.g. ideally if you could use the Profiler: Xcode Instruments usage to improve app performance when you have a slow thing running, and send me the trace so that I try to understand what happens it would be absolutely great

It was not possible to just start the binary, I get something like this:
~ % /Users/account1/Documents/Development/ossia/score/build/install/bin/score ; exit;
dyld: Library not loaded: @rpath/libscore_lib_base.dylib
Referenced from: /Users/account1/Documents/Development/ossia/score/build/install/bin/score

I get an app if I add this to the cmake command. But it is not starting either.
-DSCORE_DEPLOYMENT_BUILD=1
Slowly getting the hang of it I guess. It is incredible how long I was able to avoid cmake in my life 
the âossia-scoreâ binary at the root of the build dir, generated before âmake installâ, doesnât run either ? you shouldnât need to install anything to be able to run it, itâs only relevant when making a build to distribute to other computers

I get 3 binaries.
The âscoreâ binary complains about the Library and quits on attempt to run it from terminal or via doubleclick.
Edit: Searched the directory again. No ossia-score binary
