Title: 1.mp4
Waiting for status...
Press p to Pause/Play.

but no video on tv

I read a little document about dlna, found v2 is wrong, i will test v1 later again.

Hello, Thanks for raising this. FYI go2tv has not been tested on all TV models. I had some issues for example with some Hisense TVs too. Let me do some digging.

The "controlURL" does not look like a valid URL. This is how it looks on my Sasmsung TV

<service>
    <serviceType>urn:schemas-upnp-org:service:RenderingControl:1</serviceType>
    <serviceId>urn:upnp-org:serviceId:RenderingControl</serviceId>
    <controlURL>/upnp/control/RenderingControl1</controlURL>
    <eventSubURL>/upnp/event/RenderingControl1</eventSubURL>
    <SCPDURL>/RenderingControl_1.xml</SCPDURL>
</service>
<service>
    <serviceType>urn:schemas-upnp-org:service:ConnectionManager:1</serviceType>
    <serviceId>urn:upnp-org:serviceId:ConnectionManager</serviceId>
    <controlURL>/upnp/control/ConnectionManager1</controlURL>
    <eventSubURL>/upnp/event/ConnectionManager1</eventSubURL>
    <SCPDURL>/ConnectionManager_1.xml</SCPDURL>
</service>
<service>
    <serviceType>urn:schemas-upnp-org:service:AVTransport:1</serviceType>
    <serviceId>urn:upnp-org:serviceId:AVTransport</serviceId>
    <controlURL>/upnp/control/AVTransport1</controlURL>
    <eventSubURL>/upnp/event/AVTransport1</eventSubURL>
    <SCPDURL>/AVTransport_1.xml</SCPDURL>
</service>

Edit 1: According to http://upnp.org/specs/arch/UPnP-arch-DeviceArchitecture-v1.1.pdf (page 46)

<controlURL>
REQUIRED. URL for control (see section 3, “Control”). MUST be relative to the URL
at which the device description is located in accordance with section 5 of RFC 3986.
Specified by UPnP vendor. Single URL.

Thanks for reply.After a few times test with v1,sometimes it just works,and get stuck in waiting for status ... sometimes.

[alexballas]

Yes, v1 should be the correct one. I'll raise a PR to fix the parsing. As for the "waiting for status ..." it's really up to the device to send the Subscription notifications. I noticed that sometimes devices fail to do so. Please try the following

• Power cycle your TV (actually remove the power cable for a couple of seconds)
• Open your TV and wait a bit to properly boot and initialize all the functionalities and then try again.

I noticed similar issus with my Samsung TV when I tried sending a video the second I opened it. It's not a critical issue. Can you please confirm if PLAY/PAUSE actions still work in this case?

pause / play works well.
