In OpenPLi s there any way I can record the complete transport straight to disc without demuxing? If so how/what would I need to modify? How much work would be involved?

[littlesat]

Why do you want to do that?

[Erik Slagter]

In theory if you would use pid 0x1fff you'd get "everything", but I don't think it's actually implemented in any driver.

[athoik]

You can use dvblast to get full TP, although as Erik already mentioned it is common for all drivers for Enigma2, that they can do only hardware PID filtering and once you try to get everything with PID 0x1FFF, you get a nice failure.
 
So you will find more luck with a usb tuner that uses real open source drivers from linux
 

DVBlast can also stream the entire transponder to an IPv4 or IPv6 address :
dvblast -u -d 172.16.42.42:1235 -f 11570000 -s 27500000 -v 18
dvblast -u -d [fe80::0ca:feff:fec0:ffee]:1235 -f 11570000 -s 27500000 -v 18

But even if you had such a recording I guess you cannot use it on e2 boxes as they expect only 1 video stream in a ts file.

[athoik]

Actually you can use it!

You need to pass the correct SID in service reference and it should work.

[betacentauri]

But only with code changes. Or how can you change service ref for a recording? E2 always choose 1:0:0:0:0... for recordings. Or am I wrong?

[Erik Slagter]

Yeah I think it can be done, with some changes to enigma. For the demuxer it doesn't matter anyway.

[athoik]

Adding serviceref in a bouquet will work, at least it works for full/tp http ts stream.

So instead http:// adding file:/// ?

[Huevos]

Why do you want to do that?

Because I want to be able to inspect the complete transport stream.

 

If I say to a user grab me a complete transport stream recording, at the moment, they need a USB device. I want a way the can do it on the receiver. Maybe just by adding a simple plugin.

[athoik]

Once we can record PID 0x2000 / 8192 the rest are simple.


Currently:

Setting filter for PID 8192
FILTER 8192: DMX SET PES FILTER: Invalid argument

[Huevos]

So how do we get round that?

[athoik]

Ask manufactures to add support for recording full TP via 0x2000 PID..

[athoik]

Another way without having 0x2000 is to add as much PID as possible.

dvbsnoop -s pidscan| awk '/PID found/ { print $3 }' | xargs dvbstream -ox.ts

[Huevos]

Athoik, how can I test to see if a box does support 0x2000.

[Erik Slagter]

"Invalid argument" says it all: no driver support.

[athoik]

I am attaching dvbstream compiled for mips and arm.

Using usb card it works just fine:

But using onboard tuner is not possible at them moment... no driver support most probably for ALL.

I've heard a rumour that (original) DMM drivers could do it.

[Huevos]

@Athoik, thanks for the IPKs.

 

Just another related question.

http://192.168.1.28:...:11a0000:0:0:0:

 

Is there any way I could change that URL so it would stream the complete stream?

[athoik]

You can modify lamedb to include extra pid (type c16) or replace textpid / audio pid with 0x2000, then, if the driver supports, we might get full ts.
