there any way to read single images from the buffer using a metro?

of course, check [pix_buffer_read] and [pix_buffer_write] help for that.

Would be great to have a M1 version on deken

I might be totally wrong here, but I think that the GPU is used by shaders only

I think that GPU is used for all but video decoding and classic pixels processing...
So the more you decode high resolution media and use [pix_*] objects for effects, the more you stress the cpu .

One solution for FX is using shaders.
For media decoding... you can check what is the default backends used (check help files) and try different ones. Also There is a [certainly] more efficient ffmpeg plugin somewhere that could be compiled and used instead of the default decoder...

You might open issues here to see what could be done?

Also, I see that ofelia is far more efficient than Gem at decoding videos...

wow, even having one ceammc ui.menu displaying results in the else/multi.vsl's grinding to a halt updating-wise, no more being able to draw content onto them. looks like i'll not be able to use them then

I tried them altogether without any problem.
I would prefer [ui.sliders] if using ceammc, since it's a real compiled object and not an abstraction using dynamic patching, which is unfortunately more a hack rater than a feature in pd.

@esaruoho

I tried again today with last pd-0.54, deken -> typed "ceammc", download the package, going to browser externals->ceammc->ui.menu-help : works perfectly.

A new version of the lib will be released soon and will offer a lot of new features. I love this lib because I can make anything I want without any other external and it's functions names are much more clear and organised. A Real time saver.

@ddw_music I know there is a snapcraft for the full distribution https://snapcraft.io/pd-ceammc

What you displayed is the global ceammc help.
You can click on the link [ui.menu] in runmode it should open [ui.menu] specific help.

Also, I did rewrite the [ui.menu] help a bit...

if using external is possible, you can use ceammc, which make all this kind of stuffs more easy than pd-vanilla.

Here is an example using [ui.menu] and [symbol2any] to do it:

https://ceammc.github.io/

ceammc lib have a [snd.file] object working like [soundfiler], that support mp3 and many more format
like AAC AIFF ALAC AU AVR CAF FLAC HTK IFF MACE3:1 MAC6:1 MAT4 MAT5 MP3 MP4 MPC OGG PAF PVF RAW RF64 SD2 SDS SF VOC W64 WAV WAVEX WVE XI.

I think everybody will ask you why using a more than 12years old pd-extended software when you have "Purr-data" or "pd-2lork" (pd-extended replacement with a greater interfacre), or cyclone external with vanilla pd, or even Plugdata ? I am surprised pd-extended can still be launched in a computer today.
