[linux-dvb] libdvbapi multiproto patch ?

[linux-dvb] libdvbapi multiproto patch ?

[ChaosMedia > WebDev]

Hi,

i'm going to try to bring multiproto support to kaffeine for i'd really 
like to use my technotrend s2-3200 (dvb-s2) with it.

As far as i can tell kaffeine uses libdvbapi which is part of linuxtv 
dvb-apps repo.

So i'd like to know if there's already been any patch made to bring 
multiproto to libdvbapi ?

I don't know much about multiproto or v4l-dvb api, or dvb rfc, but i'll 
probably focus on both the wiki info  
http://www.linuxtv.org/wiki/index.php/Multiproto and a good app example 
using macros referenced also in the wiki which is getstream 
http://silicon-verl.de/home/flo/projects/streaming/

any comments, further docs, references or examples, are welcome.

thx

Marc

No. Only libdvben50221 + the ca part of libdvbapi are used.

okay thx, what's libdvben50221 compared to libdvbapi ? Are those two 
libs only used for CAM purposes ?

Anyways, i've checked DvbStream::tuneDvb and seen it uses the frontend 
declarations directly.
Good thing if i don't have to mess with a lib in the middle..

I'll see if i can manage to use some fancy macros and keep ifdef out of 
the main code.

thx
Marc

Yes, those are for cam stuff.

humm yeah but it seems that multiproto frontend.h just takes the whole 
regular frontend, for backward compatibility i guess, and puts its own 
declarations for the same values and its new ones at the bottom.

Not sure i need to go over it though if i can hide function calls from 
the libdvbapi using macros as it was done in other examples.

i'll probably need to update the api with missing dvb-s2 declarations, 
as the api's supposed to act as a layer between the driver and the 
application, and then update the api to access them or do it in the 
application, i don't really know..
