communicating between a DMS and DMR using iPhone DMC

[sudheer dantuluri]

Hi Bruno,

I'm developing an application using the upnpx library for iOS.
Followed the demo app and now I'm able to browse the contents of DMS
and also render the content as well in my application. Now I'm
planning to render the content of a DMS to a DMR (Digital Media
Renderer) (eg., rendering a video of a DMS on a DLNA enabled renderer
such as a DLNA TV) using my iPhone DMC.

It would be great if you can provide me a link or some sample code
which could give a detailed information as how to send a request to
DMR with the information required to render the DMS content.

Thanks
Sudheer

Hi Sudheer,

I plan to extend the demo with this functionality.

Thanks,

Hi Bruno,

Thanks for the great work that you have been doing for upnpx library for iOS. Also thanks for planning to extend the demo with the functionality required. Meanwhile can you help in providing a link or steps to follow which can help me achieving the functionality. I'll try to give a trail from my end.

Thanks once again for the lib upnpx support.

Have a nice day...

bye

Hi Sudheer,

In brief:

You need to have:

- the URI to play (that you find in MediaServer1ItemObject, see demo to get the objects) 

- the renderer, which is a MediaRenderer1Device (you find renderers in the same way as MediaServer1Device's, see demo).

To play media you can use the AVTransport service commands like this:

    [[renderer avTransport] SetAVTransportURIWithInstanceID:@"0" CurrentURI:[mediaItem uri] CurrentURIMetaData:@"" ]; 

    [[renderer avTransport] PlayWithInstanceID:@"0" Speed:@"1"];

Check the UPnP specs for the full set of available commands and their (and the parameters) specific meaning. 

For the above AVTransport service, the specifications can be found here : http://www.upnp.org/specs/av/UPnP-av-AVTransport-v1-Service.pdf

Kind regards,

Bruno

Hi Bruno,

Thank you very much for the support. I'll try and update you with the status. 

Thanks

Hi Bruno,

Followed the steps mentioned by you and I'm able to play a DMS content on to a DMR using iPhone DMC. Great. Thanks a lot.

Thanks

Sudheer

[sudheer dantuluri]

Hi Bruno,

Is there any method in SoapActionsAVTransport1 class to control the
volume of a DMR using an iPhone DMC client? If so, please let me know.
Now I'm able to play, pause and stop a video.

Thanks
Sudheer

Volume is set in RenderingControl, not in AVTransport.

A standard device have 3 services (R is required, O is optional):

• RenderingControl:1.0 R 
• ConnectionManager:1.0 R 
• AVTransport:1.0 O  

See 2.2 in: http://www.upnp.org/specs/av/UPnP-av-MediaRenderer-v1-Device.pdf

Volume can be set with "RenderingControl".

See the action "SetVolume" at 2.4.30. in : http://www.upnp.org/specs/av/UPnP-av-RenderingControl-v1-Service.pdf

In upnpx it will be something like this: 

int v = 50;

[[device renderingControl] SetVolumeWithInstanceID:@"0" Channel:@"Master" DesiredVolume:[NSString stringWithFormat:@"%d", (int)v] ];

Bruno

Hi everybody,
For some reasons, when I use uri from [mediaitem uri], I get an error
<The reference to entity "infokey" must end with the ';' delimiter>.
To fix this error:
NSString* itemURI = [mediaitem uri];
itemURI = [itemURI stringByReplacingOccurrencesOfString:@"&"
withString:@"&amp;"
Note that I use cling-mediarenderer for simulate a mediarender.
Best regards,
Bao Bui

Hi Bruno,

Is there any API support to handle DMPr from m-DMC? It would be great if you can provide me some help as how to proceed to achieve this functionality.

Thanks

Hi Bruno,

Facing issues while refreshing the SSDP search. I'm getting a "Socket error!" log while trying to refresh the search. I've added a refresh button which actually does the following.

Please find the code snippet below. Is there anything that I'm missing to refresh the search?

- (void)refresh
{
    [[self.upnpManager SSDP] stopSSDP]; 
    [[self.upnpManager SSDP] startSSDP]; 
}


Thanks
Sudheer

[Bruno]

Hi Sudheer,

The way to refresh is the following:

- (void)refresh
{
[[[UPnPManager GetInstance] SSDP] searchSSDP];
}

I have to take a look at the stop and start again, stop is not fully
implemented so far.

Bruno

Hi Bruno

I use the same way of your Demo on iPhone.

I add following:

SoapActionsAVTransport1* _avTransport = [m_device avTransport];

but _avTransport is nil.

I miss something ?

It would be great if you can find the problem.

Have a nice day.

Hi All:

I use Demo.

And I found my device has three service.

1. urn:schemas-upnp-org:service:ConnectionManager:1
2. urn:schemas-upnp-org:service:ContentDirectory:1
3. urn:microsoft.com:service:X_MS_MediaReceiverRegistrar:1

I can use What service to play video or audio ?

Thanks a lot.

[Bruno]

Hi Kasper,

This device is a "MediaServer" ?
If so you can use the ContentDirectory to query and access the Media:

[[m_device contentDirectory] BrowseWithObjectID:m_rootId
BrowseFlag:@"BrowseDirectChildren" Filter:@"*" StartingIndex:@"0"
RequestedCount:@"0" SortCriteria:@"+dc:title" OutResult:outResult
OutNumberReturned:outNumberReturned OutTotalMatches:outTotalMatches
OutUpdateID:outUpdateID];

See:
http://code.google.com/p/upnpx/source/browse/tags/Release-1.2.3/projects/xcode4/upnpxdemo/upnpxdemo/FolderViewController.m#72



Once you have the URL's to the media, you can render it local on the
iPhone/Mac or play it on a UPnP renderer;

To play on a remote UPnP "MediaRenderer", take the MediaRenderer
AVTransport and do something like this:

[[renderer avTransport] SetPlayModeWithInstanceID:@"0"
NewPlayMode:@"NORMAL"];

[[renderer avTransport] SetAVTransportURIWithInstanceID:@"0"
CurrentURI:[mediaItem uri] CurrentURIMetaData:@""];
[[renderer avTransport] PlayWithInstanceID:@"0" Speed:@"1"];

[Kasper]

Hi Bruno:

Yes. device is a  "MediaServer"

And I use the ContentDirectory to query and access the Media.

I get the uri Collection.

And I try each uri Path. it can't work.

I can use the same way to see photo.

but i can't use the uri path to render audio or  video.

So, I try you talk on the google group.

I can't find "MediaRender1Device".

"MediaRenderer"?

Do you mean "MediaRender1Device" ?

But the device can't transform to MediaRender1Device.

MediaRender1Device *renderDevice = (MediaRender1Device*)m_device;

PS. m_device is "MediaServer1Device" 

how to transform device?

Thanks a lot !!

Hi,

I'm trying to send a PLAY command from iPhone to Samsung TV.

This is the code:

        NSLog(@"AvTransport is %@", [render avTransport]);

        [[render avTransport] SetPlayModeWithInstanceID:@"0" NewPlayMode:@"NORMAL"]; 

        [[render avTransport] SetAVTransportURIWithInstanceID:@"ABC" CurrentURI:@"http://www.w3schools.com/html5/movie.mp4" CurrentURIMetaData:@"" ]; 

        [[render avTransport] PlayWithInstanceID:@"ABC" Speed:@"1"]; 

However, all I get is this event:

{

    AVTransportURI = "";

    AVTransportURIMetaData = "";

    CurrentMediaDuration = "0:00:00";

    CurrentPlayMode = NORMAL;

    CurrentRecordQualityMode = "NOT_IMPLEMENTED";

    CurrentTrack = 0;

    CurrentTrackDuration = "0:00:00";

    CurrentTrackMetaData = "";

    CurrentTrackURI = "";

    CurrentTransportActions = "";

    InstanceID = "NOT_IMPLEMENTED";

    NextAVTransportURI = "NOT_IMPLEMENTED";

    NextAVTransportURIMetaData = "NOT_IMPLEMENTED";

    NumberOfTracks = 0;

    PlaybackStorageMedium = "NETWORK,NONE";

    PossiblePlaybackStorageMedia = "NETWORK,NONE";

    PossibleRecordQualityModes = "NOT_IMPLEMENTED";

    PossibleRecordStorageMedia = "NOT_IMPLEMENTED";

    RecordMediumWriteStatus = "NOT_IMPLEMENTED";

    RecordStorageMedium = "NOT_IMPLEMENTED";

    TransportPlaySpeed = 1;

    TransportState = "NO_MEDIA_PRESENT";

    TransportStatus = OK;

}

Can anybody guide me to what I am doing wrong? On samsung TV, nothing happens.

Regards,

[Bruno Keymolen]

Although is say  InstanceID = "NOT_IMPLEMENTED"; can you try instance id @"0" (like you already did with SetPlayMode)?

[mbalanti]

Hi, 

that was a fast response :) Thank you!

Actually the "0" instanceID is first thing i tried and it also didn't work.

It does however produce different event (however still nothing happens on TV):

}

2012-05-03 17:01:05.069 upnpxdemo[41697:12b03] New event: {

    AVTransportURI = "http://www.w3schools.com/html5/movie.mp4";

    CurrentMediaDuration = "0:00:00";

    CurrentPlayMode = NORMAL;

    CurrentRecordQualityMode = "NOT_IMPLEMENTED";

    CurrentTrackDuration = "0:00:00";

    InstanceID = "NOT_IMPLEMENTED";

    NextAVTransportURI = "NOT_IMPLEMENTED";

    NextAVTransportURIMetaData = "NOT_IMPLEMENTED";

    PlaybackStorageMedium = "NETWORK,NONE";

    PossiblePlaybackStorageMedia = "NETWORK,NONE";

    PossibleRecordQualityModes = "NOT_IMPLEMENTED";

    PossibleRecordStorageMedia = "NOT_IMPLEMENTED";

    RecordMediumWriteStatus = "NOT_IMPLEMENTED";

    RecordStorageMedium = "NOT_IMPLEMENTED";

    TransportPlaySpeed = 1;

    TransportState = "NO_MEDIA_PRESENT";

    TransportStatus = OK;

}

Hi,

adding metadata XML made all the difference:

        [[render avTransport] SetAVTransportURIWithInstanceID:@"0" CurrentURI:@"http://www.w3schools.com/html5/movie.mp4" CurrentURIMetaData:@"&lt;DIDL-Lite xmlns=&quot;urn:schemas-upnp-org:metadata-1-0/DIDL-Lite/&quot; xmlns:dc=&quot;http://purl.org/dc/elements/1.1/&quot; xmlns:upnp=&quot;urn:schemas-upnp-org:metadata-1-0/upnp/&quot;&gt;&lt;item&gt;&lt;dc:title&gt;Test&lt;/dc:title&gt;&lt;upnp:class&gt;object.item.videoItem&lt;/upnp:class&gt;&lt;res  protocolInfo=&quot;file-get:*:video/mp4::DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=00000000001000000000000000000000&quot;&gt;http://www.w3schools.com/html5/movie.mp4&lt;/res&gt;&lt;/item&gt;&lt;/DIDL-Lite&gt;" ]; 

Now the TV at least cries that this video's format is unsupported. That's a progress :)

It looks like samsung requires metadata present.

[RastArt]

Hi mbalanti,

I'm stuck in my project with the same problem as you: create proper metadata XML for target TV. Can you please give an advice? Did you find a solution?

Thank you in advance
