Hi @picatchoof,

In your command, you save one service of the outer TS, not the inner TS which is encapsulated in the MPE PID.

If you want to extract the inner MPE-encapsulated TS and stream it over UDP/IP, this must be done in the mpe plugin using the option --udp-forward. The outer TS can then just be dropped.

Your command should be something like this. Use option --redirect to stream it to an address which is different from the one in the MPE-encapsulated UDP datagrams.

tsp -I dvb ... -P mpe -p 2002 --udp-forward ... -O drop

To save the content of the MPE-encapsulated TS (and not the outer TS), use:

tsp -I dvb ... -P mpe -p 2002 -o mpe.ts -O drop

Please read the TSDuck user's guide, 1) reference section for the mpe plugin, 2) MPE examples in section 5.2.21

Hello.
Thanks a lot for your reply.
Forgive me I tried a lot of options (udp-Forward, pid Zap,....) but no result.
I'm not sur if the issue is in my TSDuck cmd or in the Player.
I tried vlc, ffplay, mplayer but unfortunately no relevant results.

Thank you very much.

Please precisely describe:

• What is the structure of the input TS
• Which command you use
• What you expect to happen

Please also provide a sample of the full input TS

Hello
Please the Sample File is the same as in the repository. https://tsduck.io/streams/?name=russia-tricolor-mpe

The TS Structure:
My TS sample can be downloaded from:
https://we.tl/t-RZ8qBQGEtA

the TS analysis can be downloaded from:
https://we.tl/t-22hgximTHb

The command I run: and its result is:

Eexpect to happen
in My TS File (the same as the TP received from Satellite) Contains 4 Channels that are MPE.
I'm looking to extract them and make stream on Local Network.
the Stream can be either Unicast or even Multicast.
after That I have to Play them on VLC or other Player.

FYI The TS in the repository (36.0E_12168.835_V_27500.ts) contain 50 Channels.

Best Regards:

MPE encapsulates UDP datagrams into a TS. But this can be any form of UDP traffic, not only transport stream, any traffic.

In your description, you seem to expect that a media player can play this UDP content. Do you exactly know the format of the MPE-encapsulated UDP content or do you only speculate that it should be a valid transport stream?

I downloaded your file and extracted one MPE PID, using an hex dump of the UDP payload:

tsp -I file e7wa-b10.ts -P until --packet 2000 -P mpe --pid 2002 --dump-udp -O drop &>pid2002.txt

Looking into one UDP datagram (beginning of dump below), you can see that it does not look like a standard TS over UDP, neither RTP. Searching for 0x47 synch bytes, we see some form of TS, but not a standard encapsulation.

Now, we simulate a UDP forwarding, redirecting on local host. First window (sender):

tsp -I file e7wa-b10.ts -P regulate --packet-burst 16 -P mpe --pid 2002 --udp-forward --redirect localhost:1234 -O drop

Second window (receiver):

tsp -I ip 1234 -O file forwarded.ts

There is some kind of TS structure:

$ tspsi forwarded.ts 

* PAT, TID 0 (0x00), PID 0 (0x0000)
  Version: 0, sections: 1, total size: 16 bytes
  - Section 0:
    TS id:   16727 (0x4157)
    Program: 16727 (0x4157)  PID:   32 (0x0020)

* PMT, TID 2 (0x02), PID 32 (0x0020)
  Version: 0, sections: 1, total size: 31 bytes
  - Section 0:
    Program: 16727 (0x4157), PCR PID: 33 (0x0021)
    Elementary stream: type 0x0F (MPEG-2 AAC Audio), PID: 34 (0x0022)
    - Descriptor 0: Maximum Bitrate (0x0E, 14), 3 bytes
      Maximum bitrate: 0x000005A0 (1440), 576,000 bits/second
    Elementary stream: type 0x1B (AVC video), PID: 33 (0x0021)

But tsanalyze reports a lot of unreferenced PID's and other inconsistencies. Trying to play the file with VLC, there is some lines of video, then nothing.

So, my conclusion is that the MPE-encapsulated UDP content is not a standard transport stream. This is probably some form of proprietary encapsulation of a TS and the MPE-decapsulated content can only be played or decapsulated in the corresponding proprietary receiver.

Since you mention the sample TS in https://tsduck.io/streams/?name=russia-tricolor-mpe, please note that this file is just an example of MPE encapsulation. The encapsulated UDP content is not a valid TS. As mentioned on the page "The UDP stream inside each MPE stream contains a proprietary encapsulation of an HLS stream." Since HLS contains TS packets, it looks like TS but it is not. This may be the case in your stream.

As a conclusion, before trying to decapsulate the content of an MPE stream, you must exactly know the format of the encapsulated data.

Hello Thanx a lot for your response.

I Executed this command :

sp -vvv -I dvb --freq 11158000000 --symbol 5000000 --fec 9/10 --polarity vertical --delivery DVB-S2 --modulation 8-PSK -P mpe -p 2002 --udp-forward -O drop
to check I run mplayer udp://224.30.2.115:6000

after almost One minute I get a sound and very bad video screen and errors on the Terminal that runs mplayer.
you can view on the pdf at:
BTW You are right and according to the Cahnnels Provider the stream is IPTV-DASH (they use DASH and HLS Protocol)

That is exactly what I suspected. The Broadpeak nanoCDN is now a well-established solution for the so-called "multicast ABR" strategy (a very bad oxymoron in my opinion). This was also the case for the sample stream from the repository.

Since DASH and HLS are bidirectional unicast protocols, the MPE-encapsulated UDP stream is a proprietary unidirectional feed to the Broadpeak nanoCDN receiver, which in turn will act as a DASH or HLS server on the local network of the receiver. In other words, you can easily decapsulate the UDP stream from MPE but there is nothing you can do with it, at least without a Broadpeak nanoCDN receiver.

Dear Lelegard I appreciate your involvement and help.

Can you please check the tools in this Git.

https://github.com/piratfm/eti-tools

The tools such mpe2ts and the dvb-ip-mpe2ts do extract the TV channels from the The Big TS sample.

My questioning is :
Can we use such tool as piping or similar usage within TSDUCK to extract those channels?

Best regards

13 East - 12207 H
MPE pid - 1012 , one separate video stream (224.30.6.4:6000) + four separate audio streams (224.30.6.4:6020/6021/6022/6023)
would it be possible to combine these separate streams into one stream using TSduck?
MPE pid - 1013 maybe DASH (224.31.6.9:6000/6001/6002/6003/6004/6005/6020/6021/6022/6023 and 224.31.6.10:600/6020)

Hi All
Good to Know
BTW you can take a look at this webpage it can give you some details about the TPP Content
https://www.digitalbitrate.com/dtv.php?mux=12207&liste=1&live=65&lang=fr

There is PIDs
1011
1012
1013

Is it possible to tell if this TP is DVB-NIP or not?
Also Can you please supply a TS sample?
Thnx a lot

1011 - INT
1012 - IP
1013 - DASH

Thnx a lot for that.
Also is there a tools (Linux or Windows) that allow to extract and view what encapsulated in such Streams either Live or for Offline TS files
Thnx

@EnoSat Can you please tell what the plateform that shows you such details?
I tried the https://flysat.com/en/channel/64847/eutelsat-poc but don't give enough details like what you have on the Screenshoot
