| Spark[01] | hey can I get some LADSPA help here? | 12:39 |
|---|---|---|
| Spark[01] | I know it's kinda off-topic but there's not LADSPA chat I know of :P | 12:39 |
| falktx | no one uses ladspa anymore | 12:40 |
| Spark[01] | LMMS uses it, and not LV2 - which is the only reason I'm not using LV2 :P | 12:41 |

| rgareus | LV2 = LADSAP version2 so it's not really off-topic. | 14:03 |
| *** sigma6 has quit IRC | 14:03 | |
| rgareus | Spark[01]: well, just ask. | 14:03 |
| *** sigma6 has joined #lv2 | 14:04 | |
| Spark[01] | alright so my plugin is compiling fine, and it works in audacity - but it doesnt load in LMMS whatsoever | 14:07 |
| Spark[01] | I think it has something to do with the ladspa_descriptor but I'm not sure what the problem is | 14:07 |
| Spark[01] | http://pastebin.com/raw/RtG8ZABd it's towards the bottom of the code | 14:07 |
| Spark[01] | (the function is, I mean) | 14:07 |
| rgareus | I can't see anything obviously wrong | 14:16 |
| Spark[01] | hm, i wonder if its something to do with LMMS | 14:19 |
| Spark[01] | probably not a bug with LMMS but | 14:19 |
| Spark[01] | maybe I tried installing it wrong | 14:19 |
| rgareus | maybe there's already another plugin with unique ID 7888 | 14:19 |
| Spark[01] | thats possible, ill try changing it | 14:20 |
| * rgareus finds all those static variables inside a switch case hard to read | 14:20 | |
| Spark[01] | yeah, I should probably fix that, I wrote that part a while ago and i'm not sure why I did it that way | 14:21 |
| rgareus | in any case that's not an issue. | 14:22 |
| rgareus | I just don't remember what LADSPA_Descriptor looks like, and maybe some fields there are missing or not initialized | 14:22 |
| rgareus | a global static LADSPA_Descriptor desc = { all, values, here }; would be easier to check. | 14:23 |
| rgareus | does the .PortDescriptors array need to be NULL terminated? | 14:24 |
| Spark[01] | hm, i tried changing the unique id a few times, no luck | 14:24 |
| Spark[01] | I'm not sure, I'll check | 14:25 |
| * rgareus wrote his last LADSPA plugin about 8 years ago. | 14:25 | |
| rgareus | Spark[01]: are you working on windows? | 14:28 |
| Spark[01] | yeah | 14:28 |
| * rgareus just wondered about the dllexport | 14:28 | |
| * rgareus checked. NULL termination is not needed for the port array. .PortCount is what does that | 14:30 | |
| rgareus | Spark[01]: so maybe it's just that LMMS looks in a different folder for ladspa plugins? | 14:31 |
| Spark[01] | Nah, already double checked | 14:31 |
| Spark[01] | I'm gonna try cleaning up the code as per your suggestions, though | 14:31 |
| rgareus | now it gets mysterious.. | 14:31 |
| Spark[01] | maybe that will make things easier to figure out at the very least | 14:31 |
| Spark[01] | btw, what'd you mean here?: | 14:33 |
| Spark[01] | <rgareus> a global static LADSPA_Descriptor desc = { all, values, here }; would be easier to check. | 14:33 |
| Spark[01] | is that valid syntax? | 14:33 |
| Spark[01] | I've never seen that before | 14:33 |
| rgareus | Spark[01]: compare to https://github.com/x42/nodelay.lv2/blob/master/nodelay.c#L168 | 14:34 |
| Spark[01] | oh, I see | 14:34 |
| Spark[01] | I didn't know you could do that, that's neat :) | 14:34 |
| rgareus | you could go one step further and add coments.. on every line :) | 14:35 |
| Spark[01] | I should and I shall | 14:35 |
| rgareus | Spark[01]: anyway, after removing the dllexpoet, your plugin compiles here (on linux) . let's see | 14:35 |
| rgareus | loads and runs in Ardour | 14:37 |
| Spark[01] | hm | 14:37 |
| Spark[01] | I must be doing something wrong with installing it then | 14:38 |
| rgareus | maybe remove the underscore from the name? | 14:38 |
| Spark[01] | Yeah, that's a good point | 14:38 |
| rgareus | it should not make a difference. but it may some menu entries use _ to denote keyboard accelerators (on windows) | 14:39 |
| rgareus | http://robin.linuxaudio.org/tmp/sprk.png | 14:39 |
| Spark[01] | Well, thank you for all that help! :D I'll get back to you once I've made a few changes, and let you know if I've figured out a solution :) | 14:40 |
| Spark[01] | (that sounded sarcastic haha, wasn't intended to) | 14:40 |
| rgareus | Spark[01]: keep in-place processsing in mind | 14:41 |
| rgareus | aah you did. n/m | 14:41 |
| Spark[01] | oh oke | 14:41 |
| * rgareus was reading soundblur->last_data[j]=soundblur->input[i]; wrong | 14:41 | |
| Spark[01] | yeah that code isnt very readable anyway | 14:41 |
| rgareus | soundblur->output[i] is only set _after_ that. | 14:41 |
| Spark[01] | I'm gonna redo that part too | 14:41 |
| rgareus | Spark[01]: curious. Where are ladspa usually on windows? | 14:44 |
| Spark[01] | i don't know that there's a usual directory for them | 14:44 |
| rgareus | %COMMONPROGRAMFILES%\LADSPA\ ? | 14:44 |
| Spark[01] | I just put it in my user directory | 14:45 |
| rgareus | and LMMS looks there? | 14:45 |
| Spark[01] | yeah | 14:46 |
| rgareus | well, no idea, then | 14:46 |
| rgareus | I just checked https://nightly.ardour.org/ and it has no global search path for LADSPA on windows. | 14:46 |
| *** gianMOD has quit IRC | 14:50 | |
| *** gianMOD has joined #lv2 | 14:51 | |
| rgareus | Spark[01]: the plugin has no controls, maybe LMMS does not like that? | 15:01 |
| Spark[01] | hmm that's possible | 15:01 |
| Spark[01] | I don't know why that would be the case, but it could be | 15:01 |
| *** gianMOD has quit IRC | 15:08 | |
| *** sigma6 has quit IRC | 15:23 | |
| grejppi | rgareus: Spark[01]: lmms has no problem with having 0 controls in general | 15:25 |
| Spark[01] | is compiling it with MinGW a problem, if LMMS wasn't compiled with that? | 15:27 |
| grejppi | it shouldn't make a difference with a C api | 15:28 |
| grejppi | Spark[01]: why are you delete'ing static arrays in cleanup? | 15:28 |
| grejppi | *delete_descriptor | 15:29 |
| grejppi | oh, well it's not called anyway | 15:30 |
| Spark[01] | yeah i dont know what the deal was with that | 15:30 |
| Spark[01] | i removed it | 15:30 |
| Spark[01] | like i said, i wrote that a while ago and i probably made some dumb mistakes | 15:31 |

| *** edogawa_ has quit IRC | 15:50 | |
| Spark[01] | UGH i'm stupid lol | 15:50 |
| Spark[01] | It's cuz I was using 64 bit LMMS | 15:50 |
| *** gianMOD has quit IRC | 15:55 | |
| rgareus | Spark[01]: wow. it's always the "simple" part. good job tracking that down | 15:57 |
| Spark[01] | thanks :P and thank you for all your help narrowing it down! | 15:58 |
