| raphaal1 | the problem is well known: how to run lv2 plugin ui written in gtk2 inside host application that uses gtk3? | 19:47 |
| raphaal1 | gtk2 and gtk3 can not be loaded into one memory space | 19:48 |
| raphaal1 | so maybe the solution is run plugin ui in separate process | 19:49 |
| raphaal1 | i'm right? | 19:49 |
| raphaal1 | there's few more questions | 19:50 |
| raphaal1 | it is possible to put LV2_Atom to shared memory? | 19:51 |
| raphaal1 | is there a library to run ui in separate process? | 19:51 |
| raphaal1 | maybe suil supports it | 19:52 |
| raphaal1 | or not | 19:52 |
| raphaal1 | what about extensions? i found external-ui but it is barely known extension | 19:54 |
| raphaal1 | what about JUCE library? | 19:56 |
| rgareus | raphaal1: the solution: don't write plugin GUIs in GTK | 19:57 |
| rgareus | nor QT | 19:57 |
| rgareus | only use toolkits that can be completely self-contained. | 19:57 |
| raphaal1 | rgareus: ok, but i want do write host application :) | 19:58 |
| raphaal1 | there's a lot of good plugins written in gtk, like calf studio gear | 19:59 |
| *** yann-kaelig has quit IRC | 20:07 | |
| ventosus | raphaal1: I do exactly that in synthpod | 20:37 |
| ventosus | UI's in separate processes | 20:37 |
| ventosus | communication via LV2 atoms in lockfree ringbuffers in shared memory | 20:37 |
| ventosus | it is not a library, but may still be reusable | 20:38 |
| ventosus | https://git.open-music-kontrollers.ch/lv2/synthpod/tree/sandbox_ui.lv2 | 20:38 |
| ventosus | carla runs UI's in separate processes, too, got look there, too | 20:39 |
| ventosus | raphaal1: fyi, not all plugins can be run in a separate process | 20:44 |
| ventosus | some need instance-access feature, e.g. DSP and UI in same process | 20:45 |
| ventosus | s/plugins/UIs/ | 20:46 |
| raphaal1 | ventosus: thanks | 20:56 |
| rgareus | The only good (works reliable, realtime safe, mostly bug-free, responds to bug-reports, useful and well-designed DSP) plugin-set using GTK is guitarix. | 20:58 |
| rgareus | calf fails on all those accounts. | 20:58 |
| rgareus | if you want to embedd plugin GUIs, separate process is usually also out of the question. | 21:01 |
| rgareus | raphaal1: for a plugin-host: use libsuil. that's a very painless way to get plugin GUIs | 21:01 |
| rgareus | Also LV2 is pretty much the only plugin standard that allows separating GUI with a process switch. if you want to support VST or AU that's not really an option. most of those do rely on instance access. | 21:02 |
