Could you share a test build?

Sure, I've pushed everything, including the build here:
https://github.com/anibarro/MLV-App-Test/tree/master/platform/build-MLVApp-Qt_6_4_2_for_macOS-Release

Thanks! I'll have a look soon!
AV Foundation is not ffmpeg. It is original Apple encoder. Maybe you need to install the pro video codecs package from Apple.
Finally you need to run macdeployqt. Then the libs, plugins and frameworks are included.

Thanks for the macdeployqt tip It crashed at first but I saw somewhere that apps must be signed for M1 and it worked after signing it.
The AV Foundation export still fails for some reason.

I did a quick export test with a video including some effects and a LUT. Export to prores 422 with ffmpeg took 2:40 vs 3:00 on the current build

Hi,

I've updated a fork of the repository here: https://github.com/anibarro/MLV-App-Test

For now I was just quickly changing a few things to get it compiled, so it's just for you guys to see that it's almost the same code and it works a bit faster with the updated tools, but don't trust the code because it's the first time I see "Qt" and I just got the Macbook Pro this Christmas

About the video export issue, I updated to the latest ffmpeg for Apple silicon and realised that the problem is just happening with "Apple AVFoundation", all the other ffmepg configs work fine.

Edit: Just noticed that the compiled MLV App is much smaller than the one available and it doesn't include the plugins folder, I guess it's loading them from the Qt installation

Cool!
You think this is possible? Qt 6.4.0 doesn't support QtMultimedia as Qt5 did - so some things (mostly audio based, and I think some of the graphics viewer features) don't work anymore. It was the reason why I stopped porting. Did you find a solution for this?

Hi, regarding audio, yes, I had to replace a couple of things like QAudioOutput by QAudioSink, but the compiler was not complaining about any graphic function and seems to be working.
I would need to test a bit more, because there are some methods of QAudioFormat that are missing on the new version (setCodec, setByteOrder, setSampleType). I commented them out and audio was playing normally, but needs to be cheked.

Those fixes for latest llvm should be ported or included in first post maybe?
Try replacing ffmpeg with the apple silicon version here.

Thank you, I'll try this afternoon
I wanted to have everything working properly and replace as much deprecated code as I can before posting, but it was very straightforward,  just minor changes required

Hi, I use Dual ISO a lot and I thought about trying to understand that part of the code in MLVApp and see if it can be optimized or at least divide it on parallel tasks to speed things up on Apple silicon.

I installed the latest Qt 6.4.0, the latest llvm 15, did some changes so the code will compile on the new Qt version and everything looked fine at first... I was getting a few more fps with less CPU usage while playing MLV (20fps vs 17fps on the current Apple silicon release), DNG export worked, but export to other video formats where video and audio are combined is failing.
When the progress gets to 100%, it stays at a 100%, the separate video "_tmp" and audio files are generated, but they are not joined and I have to abort the export.

Any idea where to start debugging? Wasn't MLVApp using ffmpeg for the compression process? Thanks a lot!

False alarm thank god... it was just that I changed the video settings on Canon' menu to 640 from 1080p and it seems to mess things up :O
Working great, so cool that Danne is still finding time to work on this updates, thank you!

For some reason the combination of power and limitations on the EOS M with ML makes it so much fun to use

Rename ML directory, rename autoexec.bin and ML-SETUP.FIR. Copy extracted build contents to card.
Remove battery, insert battery and card. Startup camera. Report back.

I think something went wrong on the update and now the camera is not working properly. I tried with another card that worked fine this morning and now is having the same issues 

Is there anything special that has to be done on this update? I tried just copying the files but I was having problems: the screen was black and only worked with 10x zoom, some presets like 5K frtp have like 2.5K resolution... lot of weird things going on.
I tried updating the firmware like on a fresh install, but still having the same issues. I'm using the build from 1h ago.
Thanks!
