The log explains a few things.
You are trying to play an Ogg Vorbis file to the TV. This TV does not support playing Ogg Vorbis.
However foo_upnp exposes 2 additional streams URL for this file: a WAV and a LPCM stream. The TV does not support WAV but do support LPCM (LPCM is a mandatory DLNA format, WAV is not). BubbleUPnP detects that and instruct the TV to play the LPCM stream.
LPCM stream are mostly idententical to WAV except that they can be of infinite length (unlike WAVs which are files with a fixed length). My theory is that this TV consider LPCM as non-seekable stream and thus doesn't update time and do not allow seeking.
There's nothing the app can do for this: the TV cannot play ogg directly an the only compatible format is LPCM.
Thanks for the quick answer! By the way I want to say that you are the most "proffesional" dev I have ever see in internet! You answer every message, every problem, quick and clear. I wish some proffesional tv makers, mobile phones and other gadget makers had at least 20% of your personality! I hope that you have a nice job and get paid a lot! You diserve it!
To my problem now: I know that my TV dosn't support Ogg Vorbis, or flac or ape files, that's why I use foobar for decoding (and not only, I use foobar because it can read and stream cue files). But you say that TV doesn't support WAV, at least in Upnp. So, why when I browse directly to foobar's library from my TV, I can play these files and I can see the time bar moving(on my TV)?
I tried another upnp application on my phone and the same ogg files plays perfectly in my tv and I can see the time bar moving (on both my tv and phone) and I can see the total time and the file size. I checked the log file in the foobar and it says that it streams a WAV file. So how can I make bubbleupnp stream a wav file to my LG?
By the way how can I make foobarupnp showing the album art when I browse in my library directly through my tv?( in TVrsity it does show the album art when I browse)
