Hi,

 

I'm trying to understand the format of lamedb5 related to connecting to a SAT>IP server (A Kathrein EXIP 418)

 

When my vu+ duo2 connects to the sat>ip server to play BBC Two HD it sends the following PIDS:

5500,5501,5503,5504,0,258,3842,3003,18  (which are decimal)

 

The lamedb has the following lines for this channel

Transponder

lamedb5:t:011a0000:0802:0002,s:10847000:23000000:1:3:282:2:0:1:2:1:2

 

Channel

lamedb5:s:1b1c:011a0000:0802:0002:25:0:0,"BBC Two HD",p:BSkyB,c:00157c,c:02157f,c:03157c,c:04157d,c:051

c:00 157c,c:02 157f,c:03 157c,c:04 157d, c:051

These first four fields are HEX values for 5500,5501,5503,5504

 

My questions ( and I assume that I missing one mapping file somewhere

1) Where does PID 258 come from? This is the pid for the video channel and I cannot find where it is stored?

2) Where do the PIDS 3842,3003 come from?

3) I assume PIDS 0 and 18 are hard coded because I believe that all SAT>IP servers need them.

4) what is c:051 in decimal it would be 81.

 

Hopefully someone can point me to the right file.

 

Why do I want to know this?? So that I can just update the Vu+ for tuning changes and write a script to push the channels to some fire sticks that run kodi

 

Regards

 

Paul

Maybe

Many thanks, I have already seen this, and it is very helpful. But it does not answer the above questions.

[littlesat]

Sounds we need more content.... and in regards with SAT>IP which actially does a virtual 'tuner' we do not expect differences in PIDs etc.... c: identifies prefered PIDs.... where the first two numbers identify the 'target' (video, audio, teletext etc...) and the other digits the PID. It might be (speculation) that a settings editor did 'corrupt' something?

The Tuner is using PIDs correctly when connecting to the SAT>IP server. My question is where are ALL the PIDS stored, in which file?

The PIDS used (decimal) 5500,5501,5503,5504,0,258,3842,3003,18

But I cannot find where 258,3842,3003 are stored on the vu+

Pids for what? Video, audio, subtitles?

[littlesat]

 My question is where are ALL the PIDS stored, in which file?-> /etc/enigma2/lamedb and lamedb5.... when lamedb5 exits it will be read before lamedb... with saving a lamedb5 will be written....

[Huevos]

That is not true. The only file that is read is lamedb. It can be in either format. Lamedb5 is written but never read. And lamedb is always written in F4 even though it can be read as F5 and F4.

[littlesat]

Lamedb5 is written but never read

 

As far I know in OpenPLi lamedb5 is also read... when it exists + newer than lamedb. It parses much less complex.

 

But under the line all these lame, userbouquets etc... it is all parsing fantasy text file without any standard... would be nice to have e,g, all in a kind of sql database or so.... including the settings (configs) and EPG....... that would be a nice and real (cleanup) project... While other applications like settings editors may approach this database...

The relevant line from lamedb

p:BSkyB,c:00157c,c:02157f,c:03157c,c:04157d,c:050001,c:09158001010f1d:011a0000:07f2:0002:25:0:0

 

The relevant line from lamedb5

s:1b1c:011a0000:0802:0002:25:0:0,"BBC Two HD",p:BSkyB,c:00157c,c:02157f,c:03157c,c:04157d,c:051,c:0915800101                        

PIDS sent to the Kathrein EXIP 418: 5500,5501,5503,5504,0,258,3842,3003,18

Of which 5500,5501,5503,5504 are found in the DB as hex values

0, 18 are probably hardcoded because they are always required for SAT>IP AFAIK

 

This means that I cannot find 258, 3842,3003 anywhere. in lamedb/lamedb5

The hex values are not found in anything useful.

3842 F02
3303 CE7
258   102

 

If you can point me at the relevant code I will take a look...!

Since lamedb5 is not used at all... What is the connection?

[littlesat]

Lamedb5 is used. It is parsed When lamedb is Older.

[Huevos]

Lamedb5 is used. It is parsed When lamedb is Older.

No. I told you that is not true. It is never read. It is just for demonstration purposes so you can see how it looks.

 

The real file is lamedb, not lamedb5, and you can use either format in that file.

[littlesat]

The last time I looked at it lamedb5 is parsed when it is newer than lamedb.

[pharmswo]

TH point is that I do not find some of the PIDS in either... lamedb or lamedb5.

[pharmswo]

Bump....

When openpli tunes to a virtual tuner which connects  to a Kathrein EXIP Sat>IP server, so openpli is a sat>IPclient.

 

But, I cannot find where the video PID is stored for the channel... It does not appear to be in lamedb or lamedb5... Where does openpli get it from?

[pharmswo]

Pids for what? Video, audio, subtitles?

For video

[Huevos]

Automatically from the transport stream.
