Jamcast

Hi,

I'm running a trial of jamcast (version 1.6.1.133). My goal is to stream music from my laptop to my playon!hd (pohd) via upnp/dlna.
Jamcast is installed and working, because the music being played on my laptop can be 'rendered' on my phone and made hearable there.
I can also use my phone to play mp3's from my phone on the playon!hd, which works fine.
But I cannot get the music from jamcast on the laptop to be rendered on the pohd. The pohd tries to play (the screen shows so) but it seems to think the stream has 0 length and stops playing.
I've used many android upnp/dlna programs to try and do this, such as:
2play
bubbleupnp
imediashare
skifta
softmediaplayer trial
upnplay
upnp remote

only skifta and imediashare are any good.

I also have mediatomb running on a server and I'm able to play music from mediatomb (upnp server) with my phone (upnp control point) on the pohd (renderer).
Because of this I suspect that the stream from jamcast is not currently fully compatible with the POHD.

Do you think there is any way this can be fixed? I'd be happy to do some more tests, run debug commands etc, to get this working.

thanks!

Hi Scott,

Thanks for your quick response.
I've set EnableSeekTrickMode to true and power-cycled the POHD afterwards. The result when playing back now is that I hear short bursts of whitenoise both when using skifta and when using iMS.

The medialog seems to show a correct setting:

Hi Scott,

The captureasmp3 setting on true did not help, neither when seek was true and when seek was false.

Hi Scott,


Sorry for the delay. Yes I can stream to the POHD just fine, for instance using the mediatomb upnp server.
I think I'm able to use wireshark (have used it in the past) but the laptop that runs jamcast has a wireless adapter that doesn't support promiscious mode so sniffing doesn't seem possible.
I can sniff under linux but because the controlpoint is on my phone it's a bit of an odd situation: All connections are on switches so I don't see all traffic at the same time when sniffing at any point in the network.

Could you be a bit more specific in which data you need to have?
For instance the tcp dump of the jamcast machine, dump from the POHD, dump from mediatomb or dump from the phone ? And what traffic specifically? There is a lot flying around. Is the control and the data separated by port nr or protocol for instance?

thanks,
