[Zapping-misc] Parse raw vbi data

[anshul <ans...@gm...>]

hello,

I am trying to parse raw vbi dumped from GXF file.

What I have done so far?

Step 1) I created a local structure of vbi_raw_decoder

Step 2) Initialized decoder

vbi_raw_decoder_init (&rd);

Step3) Then Filled mine vbi specification in rd structure, like scanning 
line and sampling format


Step 4) Calledvbi_raw_decode with initialized rd.

Problem: I get seg-fault while decode, and that is because 
vbi_raw_decode assume that  I have initialized pattern inside rd 
structure. so my problem is that I dont know how to initalize rd->pattern
can  any point me with some working example where patter would be 
initalized and I get the information of how it has to be done.

I have not added my complete source code which use this library and dump 
file of vbi.
but if it would help then I can attach or keep it on shared drive as you 
wish.

Disclaimer: I am using this library first time, so dont know about rules 
and regulation of this mailing list
please pardon me and correct me if this is not the way to communicate.

Thanks for this wonderful library
Anshul
