IPTV-0.2.4 plugin not works for me, I can see steel picture only, from time to time. But on info screen of plugin I can see stream's data. I test softdevice and xineliboutput. Anybody try iptv?

If you're using an external application (like vlc) to transcode the video stream and you see only still pictures, you'll most likely need a faster CPU.

I use native iptv mpeg2 stream, from xDSL. With vdr-1.6.x and 1.7.0 all works fine.

Sometimes when change channel I can see normal iptv aprox. 3 sec, but after still picture again... CPU load low.

VDR's PAT/PMT scanner detects changes in pid information usually after a few seconds and the channel it retuned as your log states. If you look at the change, you'll see that VDR changes the video stream type from MPEG2 (2) to an invalid/reserved (0) value. Software decoders might rely on that that information and therefore cannot display the video.
As a quick hack, you should disable PAT tables in IPTV's section filter (or disable channel updates in VDR) and manually edit the channel entry to use a correct video stream type (501+501=2).
Now, the real question is why the video stream type is marked as zero in your streams: a bug in vdr, a bug in iptv plugin, or some kind of attempt from your provider to allow only their proprietary hardware? If it's the latter one, you could try simply to make VDR detect stream type 0 as a MPEG2 (0x02) or H264 (0x1B) stream in pat.c, although I cannot see how you could end up with non-zero video pid with zeroed video type in current VDR code base. Are you using any other VDR patches than the pluginparam?
You could always provide us a stream dump for further analyzing: $ emcast 127.0.0.1:1234 > dump.ts

If I change in pidscanner.c IptvChannel->SetPids(Vpid, Ppid, 0, Apids, ALangs, Dpids, DLangs, Spids, SLangs, Tpid); to IptvChannel->SetPids(Vpid, Ppid, 2, Apids, ALangs, Dpids, DLangs, Spids, SLangs, Tpid);
I can see all channels.
Than I change pidscanner.c .............. #if defined(APIVERSNUM) && APIVERSNUM >= 10700 SI::PMT::Stream stream; int Vtype = stream.getStreamType(); IptvChannel->SetPids(Vpid, Ppid, Vtype, Apids, ALangs, Dpids, DLangs, Spids, SLangs, Tpid); #else ................
And add debug line in remux.c in vdr, and see:

What is a stream type = 47 ??!
Success if I disable pid and sid update in iptv channel menu. Disable PAT tables not help...
If I remove all changes in pidscanner.c, I have:
vdr: [16900] switching to channel 270 vdr: [16974] IPTV streamer thread ended (pid=16900, tid=16974) vdr: [16973] receiver on device 9 thread ended (pid=16900, tid=16973) vdr: [16977] receiver on device 9 thread started (pid=16900, tid=16977) vdr: [16978] IPTV streamer thread started (pid=16900, tid=16978) vdr: [16900] stream type = 00, pid = 901 vdr: [16900] stream type = 04, pid = 902 vdr: [16980] [softdevice-audio]: Xrun (at least 451.542 ms long) vdr: [16980] [softdevice-audio]: xrun
vdr not change stream type from 0, which give him a pidscanner.
Who must change stream type to actual, vdr or iptv plugin?
I can send a ts dump, how long and what mail?
Thank you.

Thanks. That is a bug in the current pid scanner and will be corrected in the next version.

IIRC, it's a reserved area.

VDR. However, if the IPTV stream doesn't contain correct PAT sections, the pid scanner should be enabled in the IPTV plugin to do a basic video and audio pid detection.

I guess there's no need for that anymore.

My suggestions.... 1. My iptv provider streams many channels with identical pids, and vdr not very love such channels :-) If in sidscanner.c chandge cChannel *IptvChannel = Channels.GetByChannelID(channel.GetChannelID()); to cChannel *IptvChannel = Channels.GetByServiceID(Source(), Transponder(), assoc.getServiceId()); vdr iptv plugin can work with duplicate pids channel more correct.
May be is a other way.....
2. My iptv provider retranslate sat channels in iptv, after decrypting, but not remove CA Descriptor from stream. And when I enable "use section filtering" and not disable PAT my iptv channels geting CA descriptor and vdr can't display this channels. Be a fine have option for disable use CA Descriptor in iptv, or vdr can be ignore it.
Thank you.

You'll need to patch VDR for this: comment the "Channel->SetCaIds()" line at the end of pat.c. This affects all channels, so you might want to still keep the CA updates for normal channels: "if (!Channel->IsPlugin()) Channel->SetCaIds()". Remember to clear out the CA field in channels.conf after the change.
