Maybe we need to create our own specs for DVB-S2 ? ;-) Well, probably
that explains why even though there is enough information, drivers don't
work good enough (there is bad hardware though, not talking about that).
I hear people crying to open up nVidia driver source. why ? Well, nVidia
does a great job of getting the driver moving. Well if the source and
info were to be given to the guys, well it would've been another sad
story. No wonder they don't want to open up. I highly appreciate the
fact that they don't open up, even though personally i would like to see
it Open sourced.
I haven't been in DVB development as long as you, but i certainly am
sane enough as to include that which belongs to the spec and to the
driver into the API/driver. I really don't understand how you can call
it wrong and certainly "add them as flags (u32)". Well __u32. Sorry,
"The world is coloured, rather than Black or White", Insane !
This discussion certainly reminds me of the discussion on the SAS
discussions on LKML, where "Linus finally said specs are wrong." Well,
if specs and device vendors are wrong .. well i wonder who is right ..
Just ask yourself:
- Who are the people who wrote the DVB-S2 spec?
- Why did they write it the way it is?
- Which parts of it are relevant for whom?
And then:
- What are your goals for the Linux DVB API?
- What is the price to pay for achieving this goal?
If your goal is to support every wrinkle of the DVB-S2 spec
just for the theorectical case that someone could need it sometime,
then your goal is different from mine.
If someone can explain to me how advanced features of
DVB-S2 are useful *today*, and how an application
would work that makes use of these features, I'm
all ears. Otherwise my advice is: KISS.
Anyway, i haven't met/or talked to those people who have written the
specs. Well DVB-S2 does indeed address the drawbacks of DVB-S. That much
i can understand from the specs.
I am not asking for supporting all the damn wrinkles as you said. Why
are you looking at adding cell-id's and or stream priorities to DVB-T ?
Well, if you say that you want to be in the stone age fine. You can say
that very plainly, that "we shouldn't be adding any more feature into
the Linux DVB API". It is the most perfect API that one can ever find
and sleep happily with that thought.
The same way i am doing it for DVB-S2. There was an announcement from
BBC that they will be making their new test stream as a low priority
stream, but the last minute they switched their ideas and they moved to
the High priority stream
Julian,
Can you please confirm it. Johannes would probably like to hear it from
your mouth than mine ..
Hope that clears it up
Manu
