Topic: Not all notifcation events are fired (Read 9604 times)

Hi,

I wrote a little plugin in C#. The plugin uses Mr GriZ's Template to begin with. I've found out how to register the MjEvent Routine in C# but I now see that not all Events are fired (is this related to the Zone Problem I read earlier? (MCC: NOTIFY_TRACK_CHANGE only works for active zone? from Gappie)). When a track changes, notification are fired (see below) but when f.i. the Equalizer is changed I don't get the MCC: NOTIFY_PLAYERSTATE_CHANGED Event. In fact I don't get any other events than the ones printed below which are fired when the player changes tracks. I've downloaded the latest version I could find (12.0.207) but that didn't help.

Paul.

MJEvent type: MCCommand/MCC: NOTIFY_PLAYERSTATE_CHANGE/0
MJEvent type: MCCommand/MCC: NOTIFY_TRACK_CHANGE/0
MJEvent type: MCCommand/MCC: NOTIFY_PLAYERSTATE_CHANGE/0
MJEvent type: MCCommand/MCC: NOTIFY_PLAYERSTATE_CHANGE/0
MJEvent type: MCCommand/MCC: NOTIFY_PLAYERSTATE_CHANGE/0
MJEvent type: MCCommand/MCC: NOTIFY_TRACK_CHANGE/0
MJEvent type: MCCommand/MCC: NOTIFY_PLAYERSTATE_CHANGE/0
MJEvent type: MCCommand/MCC: NOTIFY_PLAYERSTATE_CHANGE/0

I've passed Paul a link to the latest beta build for Dev purposes only.

PaulSinnema · « **Reply #2 on:** April 14, 2007, 03:25:06 am »

Downloaded that one. Problem stays the same.

PaulSinnema · « **Reply #3 on:** April 14, 2007, 03:29:42 am »

The skin change notification does work:

MJEvent type: MCCommand/MCC: NOTIFY_SKIN_CHANGED/0

I'll test the other events on monday...

John,

There's a problem with the MCC: NOTIFY_SKIN_CHANGED event. It fires a bit too early. When I try and change the colors for the plugin at the time the event is fired, probably not all the colors have been set for the skin correctly yet. When however I set the colors on the Paint event of my MainInterface Panel (UserControl) the color appear correctly (this is how I have implemented it for now).

John, I can confirm his results.

The Wiki says

Quote

MCC: NOTIFY_PLAYERSTATE_CHANGED
Fired when a the player state changes
Change in volume
Change in mixer
Change in image being displayed
string3 is the zone

But I only seem to get them just before a track change (I assume by the image changing ?). I can't trigger one by adjusting the volume or mixer settings. I only use one zone.

My logs look like this...
EQdbCtrl::MJEvent(MJEvent type: MCCommand, MCC: NOTIFY_PLAYERSTATE_CHANGE, 0) EQdbCtrl::MJEvent(MJEvent type: MCCommand, MCC: NOTIFY_PLAYERSTATE_CHANGE, 0) EQdbCtrl::MJEvent(MJEvent type: MCCommand, MCC: NOTIFY_PLAYERSTATE_CHANGE, 0) EQdbCtrl::MJEvent(MJEvent type: MCCommand, MCC: NOTIFY_TRACK_CHANGE, 0)

PS. I'm using 214.

PaulSinnema · « **Reply #11 on:** April 17, 2007, 12:47:57 am »

My plugin shows all the events in the plugin (for now). Would you like a copy of the installation exe?

John Gateley · « **Reply #13 on:** April 17, 2007, 04:44:41 pm »

There's a typo in the docs and shown above. The PLAYERSTATE event is:

NOTIFY_PLAYERSTATE_CHANGE

It is not:

NOTIFY_PLAYERSTATE_CHANGED

Sorry...

Had already noticed that and changed it in the Wiki.

scthom · « **Reply #15 on:** April 18, 2007, 10:48:12 pm »

I indeed had my handler looking at the wrong keyword, but even fixed, I still do not recieve the event as frequently as expected (only at track change).

Now using 216, still unable to trigger this event with volume or mixer changes. Is just changing the slider enough or is there something else I'm supposed to do? Or, perhaps I misunderstand it's application? (Is it only triggered by a function call to the mixer to set the mixer?)

John Gateley · « **Reply #16 on:** April 19, 2007, 11:17:57 am »

Sorry - misread the code when doing the docs.
The NOTIFY_PLAYERSTATE_CHANGE is fired on a change in player state, like going to the next track, stop, pause, or start.
I added two events for the volume and the mixer:
MCC: NOTIFY_VOLUME_CHANGED
MCC: NOTIFY_EQ_CHANGED

Available next build...

Can I or can I not get this latest build? I'm quite frustrated at the moment and already planning to give it all a big kick into the Trash Can. It's impossible for me to program anything with all the bugs and missing stuff in the version I have (213). Are you going to encourage or dissapoint me?

Thank you for your help, fixing document pages for JRiver in Wiki

Thanks King,

I believe everybody else is ignoring me here. What's the matter with you people out there?

I'm an experienced programmer who is trying to build a plugin for a friend for whom I installed (and bought mind you) MC to play music in his Pub in Zürich. He would like to have a plugin that can set certain properties based on song/genre/album (haven't quite found all the possibilities yet). Now is it so hard too get a little help from my friends so I can get along. DO YOU WANT ME TO GET ON MY KNEES AND BEG! Ok I'm on my knees now, PLEASE HELP

!

Paul.

PaulSinnema · « **Reply #20 on:** April 21, 2007, 01:25:41 am »

Just to show you guys I'm not fooling arround. This is what I've programmed so far but now I'm stuck and need your help:

All written in C# with Visual Studio 2005 Professional Edition and SharpLibrary (http://www.sharplibrary.com/) Components.

Colors are taken from the skin and automatically set.
The Field 'AutoEQ' is automatically added to the Database (need it to set features on a per song/album base).
The equalizer already syncs with the MC Eq.

In the Search field a profile can be entered and the result is shown in the grid (would have been nice If I could enhance the pop-ups in MC with my functionality and use the Search and select logic already present in MC, but didn't see that posibility yet).
Planning to do bulk changes to the AutoEQ Field here.

Craig · « **Reply #21 on:** April 21, 2007, 03:07:36 am »

Paul,
You're not being ignored, We've been trying to get developments made to the event SDK since it was introduced and at the moment there is more progress being made than ever before.

I guess the problem is that they're invisible to 99.9% of users.
It'll get there but you can't expect minority changes to be made overnight.

Craig

PaulSinnema · « **Reply #22 on:** April 21, 2007, 04:56:24 am »

Craig,

You're missing the point here. I see that changes are made to MC to allow programmers to hook into MC. But the changes made are not available to me because I can's get the overnight builds. I've been waiting for over a week now to get on with my programming but I'm stuck because of missing functionality and bugs (solved in the latest build).

Paul.

PaulSinnema · « **Reply #23 on:** April 21, 2007, 04:59:06 am »

Made the plugin to look like this now. Wow, sharplibrary is realy cool

scthom · « **Reply #24 on:** April 21, 2007, 10:45:05 am »

Paul,

I don't think anyone was doubting the sincerity of your requests. But all the "Bumps" and rapid-fire requests were a little annoying, and as Craig mentioned, keeping up with the developers is not their highest priority. I'm guessing your enthusiasm just came off as annoying. Your "Take it or leave it" response probably didn't buy you any points, either

Don't give up!

PaulSinnema · « **Reply #25 on:** April 22, 2007, 04:55:11 am »

Scot,

You're right. I've been a bit impacient but can you really blame me? I'm a professional IT Consultant in my daily business and when I have a problem with something I consult my colleagues to help me. I was hoping for the same attitude from JRiver. Supporting developers should be a top priority. There is no way to get more functionallity into MC FOR FREE than by supporting enthousiastic people like you and me. If I get supported my attitude will be to think of more functionality to be build into MC and I do have some nice ideas at the moment. On the other hand if I get put down all the time my enthousiasm is going to deminish rapidly (my time is precious to me too). At the moment I'll stick with this little project for now but I don't like to spend my energy to get arround bugs and missing functionality in MC. That's why I need all the help I can get. So once again, Please help!

Paul.

Hi,

Moving the Volume slider generated an Event with empty Strings s1, s2 and a '-1' in string s3.

MJEvent type: MCCommand//-1
MJEvent type: MCCommand//-1
MJEvent type: MCCommand//-1
MJEvent type: MCCommand//-1
MJEvent type: MCCommand//-1

Changes to the Equalizer produce the following Events

MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1

Does the -1 have a meaning in this case? It may be usefull to tell which Band is being changed. When a preset is choosen I get 11 Events (I guess 1 for each Band Changing). Causing me to loop over all my bands (11 bands) getting the Values for each band which result in 11 * 11 times getting the Values.

Paul.

That's not happening for me, I just get one. But I am not implementing my own sliders, I rely on the DSP studio for that. However, when I set the EQ, that does trigger another event. Which seems like it should be correct, since I should get an event if something else changes the EQ setting.

PaulSinnema · « **Reply #28 on:** April 25, 2007, 11:03:15 am »

Oops I see now that my text is not quite right. s1 does contain the correct string. Only s2 is empty. I'll debug the Preset thing tomorrow to see if Scot is right.

PaulSinnema · « **Reply #29 on:** April 25, 2007, 12:40:12 pm »

John, Scot

Couldn't wait until tomorrow. Here's the result. This is what I get when I select a Preset:

MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1
MJEvent type: MCCommand/MCC: NOTIFY_EQ_CHANGED/-1

Exactly 11 Events. So my guess still stands. 1 Event for every Band (which makes sense).

Paul.

No, string3 is not used (and I got it right in the wiki docs too!).

The way events are signaled: a single slider change signals an event that must be sent to a lot of different interested components (such as the 11 slider controls). This also means that the single change generates multiple events for automation. Your plug-in will have to be careful to handle that correctly. Maybe in the future the architecture will be nicer...

Paul, does each of your sliders attach to the event interface, or do you have one master routine that attaches just the one process?

I have 1 Routine that handles the Events from MC. On each 'EQ Changes' event from MC a Routine is called that sets all the Sliders (loops over all 11 EQBand(n) and sets my corresponding sliders accordingly.

Yeah, I expected that. But not quite what I asked. How do you attach to the events interface? I suspect you are attaching 11 times (once for each slider), that's why you get 11 events instead of just 1.

John Gateley · « **Reply #37 on:** April 27, 2007, 09:46:02 am »

When you change a slider or turn the eq on or off, MC starts with a single event. The event processing code says "who is interested in the event" and sends it on to the 11 sliders (11 events). The slider event processing code then sends it on to Automation, so the plug-in gets 11 notifications of the event.

Not the cleanest approach, but it works. I'll improve it later...

PaulSinnema · « **Reply #38 on:** April 27, 2007, 01:11:42 pm »

Aha, I didn't quite understand Scot here. Now I do. In MC Internaly you can add listeners to the Event. In my plugin I have to wait for MC to fire my MJEvent (11 times). Ok, yeah right, not very OO but it works. But heck, the whole of Windows works like that (at least the older versions).

That's what I'm thinking Paul's code is doing (not sure) -- with C++ and the way I attach, I do not have that problem. I (correctly) only get the one event.

My (very brief) testing with C++ gave me multiple events. I'm not sure what's different. I tried two different tests: turning the eq on and off, and moving a slider.

What remains is the question: "How do you attach?", isn't it?

scthom · « **Reply #43 on:** April 29, 2007, 10:51:57 pm »

Oh, are you asking me?

I'm not 100% sure of why it works right for me. Couple of potential reasons...

I only have to attach once because I'm using a composite control for my dialog.
I don't use additional sliders, so I don't have as many SetEQBand calls to make. Which tend to cause more events to be generated.
C++ versus C#
