    What is it?
    It is possible to watch TV not only via DVB-T, DVB-S or DVB-C, but you can also watch TV via DVB-IP aka IPTV. The TV streams are transmitted on your internet connection. More and more ISP's offer TV on their networks.

    DVB-IP in MediaPortal
    The good thing is that the TvServer already comes with a software DVB-IP MediaPortal IPTV Source Filter card. You can enable it in the TV config under "TV Servers" -> <your Servername>.

    The bad thing is that version provided with MP is little bit older and many people have problems with this version (especially in UDP part). There are (at least) two threads concerning about DVB-IP filter: older one and newer one. There can you find information about development. Thanks Dimka and Stepko for developing this version.

    New version, supported protocols, supported URLs' formats
    New version of filter should be more stable and reliable than version provided with MP. Latest (non-experimental) version supports:
    • file sources
    • HTTP sources
    • UDP sources
    • RTP sources
    • RTSP sources (only IPv4, doesn't support specifying network interface)
    Supported URLs' formats and examples
    File sources
    • Formats
      • file://[server]/path
    • Comments
      • all spaces in path have to be replaced by %20
    • Examples
      • file:///c:/temp/video.ts
      • file:///c:/temp%20folder/video%20with%20spaces.ts
    HTTP sources
    • Formats
      • http://server[:port]/path
    • Comments
      • server can be DNS name or IP address (IPv4 or IPv6)
      • authentication is not supported
      • proxy server is not supported
      • SSL not supported (HTTP port 443)
    • Examples
      • http://test.tv/channel
      • http://test.tv:80/channel
    UDP sources
    • Formats
      • udp://[[sourceServer[:sourcePort]]@]localServer:localPort
    • Comments
      • sourceServer and localServer can be DNS name or IP address (IPv4 or IPv6)
      • localServer can be unicast or multicast IP address
    • Examples
      • udp://233.10.12.1:7777
      • udp://@233.10.12.1:7777
      • udp://192.168.15.50@233.10.12.1:7777
      • udp://192.168.15.50:4477@233.10.12.1:7777
    RTP sources
    • Formats
      • rtp://[[sourceServer[:sourcePort]]@]localServer:localPort
    • Comments
      • sourceServer and localServer can be DNS name or IP address (IPv4 or IPv6)
      • localServer can be unicast or multicast IP address
      • if failed with parsing of RTP packets it automatically switch to UDP protocol
    • Examples

    Need your help
    New version was hugely tested, but still can be there some issues - in performance or in stability.

    Compatibility
    New version is compatible and tested with MP 1.1.3, MP 1.2.0 Beta, MP 1.2.0 RC, MP 1.2.0, MP 1.2.1, MP 1.2.2, MP 1.2.3 and MP 1.3.0 (Alpha, Beta, RC, final).

    Installation
    For proper filter working you need Microsoft Visual C++ 2010 Redistributable Package (x86).

    To use the new version just follow these simple steps:
    1. stop the TV service in the TV-Server Configuration (under "Manual Control")
    2. go to the TV server folder (e.g. C:\Program Files\Team MediaPortal\MediaPortal TV Server)
    3. optional - make a backup of the original MPIPTVSource.ax and MPIPTV_*.dll files (if exist)
    4. copy or replace files in TV server folder with files in MPIPTVSource.zip archive
    5. optional - copy or replace MPIPTVSource.ini file in TV Server data folder (e.g. [DRIVE]:\ProgramData\Team MediaPortal\MediaPortal TV Server)
    6. optional - edit configuration in MPIPTVSource.ini file
    7. start the TV Service in the TV-Server Configuration
    You also need a playlist file for your ISP to scan channels.

    Specifying network interface card
    Caution: This part was tested only with MP 1.2.0, MP 1.2.1, MP 1.2.2, MP 1.3.0 (Alpha, Beta, RC) and it doesn't work with RTSP protocol (sorry for that).
    There is workaround how to specify network interface card. You'll need to change your existing playlist urls to another form (and also use latest version of MediaPortal IPTV Source Filter) and rescan your channels. Assume that you have current address
    Code:
    udp://233.60.10.5:1234
    and you want to specify 'Local Area Connection' network card. The address must be transformed to
    Code:
    C:|interface=Local Area Connection|url=udp://@233.60.10.5:1234
    To be correct, the first letter ('C') can be anything, but the second must be colon (':').

    Change SID and PID in stream
    If you have provider which change SID and PID values in streams (e.g. when provider obtains streams for various sources or simply has its own set-top-boxes which don't care about SID and PID) then with every change you need to rescan channels to get them work back. If it happens often, it's very annoying. I've added possibility to change these values in IPTV filter, so you will not need to rescan channels when provider change these values. Of course, I assume that channel is still streamed on same address. The way how to change values is same as for specifying network interface card (so, you will need to change your playlist file):
    Code:
    C:|url=udp://233.10.12.1:7777|SidValue=10|PidValue=50
    where SidValue is new SID and PidValue is new PID (ONID). For each channel you need another PID value (valid PID values are from 32 to 8190), SID values can be same. You don't have to know old SID and PID values. Changing SID and PID values doesn't work in case that in stream isn't only one channel.

    Hi Attached the TVServer logs. Not sure if it helps, cause I get 'no free card available' on the mediaportal client when I want to view a channel that is already streaming on the MP Server. It only does this for DVB-IP, for DVB-S and DVB-C it works oko.

    Thx for having a look at this.

    Regards,

    DJ

    It helps, because allocating free card is Tv Server task. It's clear in log, that no free card was found. It's not problem of IPTV filter, but Tv Server has wrong implementation of DVB-IP card. I'll check if same issue has MP 1.2.0 Beta. If yes, I'll try to investigate where is problem.

    Ok, thx a lot for checking this. To describe exactly what was done:

    - 1 DVB-IP card is defined in TV Server
    - DVB-IP channel is streaming on HTPC (TV Server and MP Client running on same machine)
    - Another MP Client is running on Laptop. When trying to tune to the same DVB-IP channel then it says 'no free card available'
    - When repeating this test with a DVB-C or DVB-S channel then this works fine; the same channel shows on both Laptop and HTPC, even when there is only 1 TV card defined (so no multiple tuners available).

    Version is MP 1.1.3, OS Windows 7

    Hi,

    I can confirm that same issue has MP 1.2.0 Beta. I've started thread, where I hope this issue will be fixed.

    Hi.
    I don't know if I have the same problem as yours or not.
    In my case http dvb-ip scan results in nothing with "no PMT found" error.
    vlc plays them normally.
    Maybe you have some advices.

    I assume that you're using MP 1.2.0 Beta. If yes, than your problem was solved in this thread (this post). Fix is in current SVN (it was fixed in SVN revision 27966), so you can download and build new MP.

    Thanks, scan is working in 27966 with your source filters.
    I found if somehow iptv channel is detected as not FTA when you try to preview it you get "ChannelNotMappedToAnyCard"

    Can you reproduce this again and attach logs? Maybe it's some bug and it should be reported.

    My logs with with fta detection problem.
    I droped mysql database and did full rescan.
    I suppose channels are the same in each time.
    tv-15, tv-19, tv-17 are shows as not fta. It is interesting but provider name "RSCC"(don't know what doesit mean) in tv channels list is shown only for them.
    If i try to preview one of them I get "ChannelNotMappedToAnyCard"
