Auto3D plugin for MediaPortal 1.2 - 1.12 (GUI & TV/Beamer) (5 Viewers)

@matt: What kind of codecs have you selected? Recommended is LAV filters. I don't have any problem with those.

@wouter1971 - I am using LAV filters. I don't have any other playback issues - only when trying to switch in to the 3D mode using this plugin.

Added new version with a modified UPnP.dll. The old version had 2 problems. A memory leak and high CPU usage, which where found by @Sebastiii while searching for the reason of a MediaPortal crash described here:

https://forum.team-mediaportal.com/threads/fontengine-crash-need-help.122889/

@Sebastiii fixed the memory leak and I (hopefully) fixed the high CPU usage. I did some test on my machine and everything seems to work again.
So it's time to see if this really solves all Problems. I attached a new version of the plugin containing a new UPnP.dll at the first post in this thread.

Auto3D_1.6.pre_4.mpe1

Hi Marcus,

I have let running mp the whole night :

I have stop the music and now on Home screen it stay @ 14-17 % on my i7 3770k (it's too high)
Starting a video and it take too long to start and in fact didn't start and @ the end i need to kill MP

So the change maybe didn't go as fast memory/cpu usage than before but still not ok.
In Auto3D, it was set as 'No device', maybe when set to 'No device', we should get ride of UPNP scanning ?

Ps : i will try to set a device (even if i can't setup one) to see if it's different

Hi,

I have let running MP this morning (with Samsung TV as setting) and it's the same 12-13% and 620mb.

I have try the app that use UPnP.dll alone and on each network scan (i do it manually) APP take around 2-5 mb and a little CPU usage is happening while the scan.
So it lead to MS method that does that.

This APP tool scan only one and not always (that is that i have try to avoid) but here for Auto3D we need to scan @ regular basis to detect new arrived material.
how we can fix that ?

For sure for now it's not usable and it's not cool

Good question. Which API-call do you mean that causes the Problem?

I used the Intel UPnP Library, because it was free and I didn't want to invent the wheel a second time.

Perhaps I should think of switching to another UPnP framework.

Hi,
I have do a quick look and i think it's in :

                ArrayList CurrentAddressTable = new ArrayList();
                NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
                foreach (NetworkInterface i in interfaces)
                {
                    if (i.IsReceiveOnly == false && i.OperationalStatus == OperationalStatus.Up && i.SupportsMulticast == true)
                    {
                        IPInterfaceProperties i2 = i.GetIPProperties();
                        foreach (UnicastIPAddressInformation i3 in i2.UnicastAddresses)
                        {
                            if (!CurrentAddressTable.Contains(i3.Address) && !i3.Address.Equals(IPAddress.IPv6Loopback)) { CurrentAddressTable.Add(i3.Address); }
                        }
                    }
                }

If i'm not wrong from memory it's :
NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
for sure it eat memory about cpu usage maybe too but not 100% sure.

Marcus,

There also a plugins : https://forum.team-mediaportal.com/threads/working-on-new-mp-upnp-renderer-process-plugin.104959/
I didn't test it but seems to use the same Intel source but worth a try to test if i get cpu/memory usage with it too

 

[Marcus Venturi]

Hi Sebastiii, I did a further test with the DeviceSpy.exe and can confirm that there is still memory lost.
So the error in the UPnP.dll is still existing, and as I could reproduce it with the DeviceSpy.exe it should happen also with the other Apps using the UPnP.dll, maybe nobody has recognized this yet.

 

[Sebastiii]

And it seems that it trigger CPU usage quickly after MP start (for it does) lol.
That's a pain and will be hard to fix it seems.
