Xvdr and vdr-plugin-iptv not sending data to XBMC

[Louro]

Hello,

I´m trying to make IPTV plugin work with xvdr and XBMC, but i can't manage to get any picture on XBMC,

The channel changes to IPtv plugin but in XBMC the buffering is stuck at 0%.

Here is some logs http://pastebin.com/QYhqq4Lz

Thanks,
Louro

I have looking and making some debugging at the code and found this:

 unsigned int ts_pid = TsPid(buf);

  m_FilterMutex.Lock();
  cTSDemuxer *demuxer = FindStreamDemuxer(ts_pid);
  if (demuxer)
  {
    demuxer->ProcessTSPacket(buf);
  }
  m_FilterMutex.Unlock();

  buf += TS_SIZE;
  size -= TS_SIZE;
  used += TS_SIZE;

The demuxer is always NULL, so we havent created any demuxers...

[Louro]

a bit more debuging

// get cached demuxer data
DEBUGLOG("Creating demuxers");
cChannelCache cache = cChannelCache::GetFromCache(uid);
if(cache.size() != 0) {
DEBUGLOG("Creating demuxers --- Cache != 0");
cache.CreateDemuxers(this);
RequestStreamChange();
}
else
DEBUGLOG("Creating demuxers --- Cache == 0");

The demuxers are not created since the cache.size is always == 0

Your stream has to be a real transport stream.
It must contain PAT/PMT information. Without these tables XVDR is unable to
find stream information.
I dont know if the iptv plugin is able to create these tables.

Hi Alex,

Ya that is the problem IPTV doesn't create PAT or PMT data, i was trying to feed IPTV just a mpegts file that i have created via FFmpeg, but ofc it doesnt contain PAT or PMT, only Video and Audio.. Will need to find a real dump of a TS stream to see if it works after all.

Will report back later.

It just a small report after some more testing

I have used dvbstream to grap a TS from my dvb card and dump it to a .ts file. Then i feed it to IPTV plugin but nothing is happening.

From my syslog i can see that everything goes ok until iptv start buffering and then nothing else happens.
While if i use my DVB card, xvdr start scanning PMT packets.

You can find below the two syslog, one for iptv+xvdr and another for dvb+xvdr

Any help pointing on the right direction is very welcome and in advanced thank you so much for your time Alex.
PS: I have read some parts of xvdr code, and i need to say, fuc.. that is really good coding.

Regards,
Louro

I believe I'm experiencing the same issue with vdr-plugin-pvrinput.

[Louro]

The problem is solved, after reading almost all the code and understanding it all, lots of hours debugging all came to an end.

Needed to activate SID scanning on IPTV, on livepatfilter.c line295 the comparation:
if (Channel && (Channel == m_Channel)), was failing since the channel didn't had the ServiceID set, when vdr starts and IPTV plugin parses the channel information this information is not yet available.

Reading from a full TS file dumped from my DVB card with 10 channels encrypted and free worked without a problem. Also tried the http://www.bigbuckbunny.org/ TS file FULL HD, 100% working. Next step will be to convert a FLV stream from the net to TS using Ffmpeg add feed it to iptv.
