Hi ravi,
whatever i told, it was my understanding.
After going through the doc you refered, what i understood is
1. Initially we need to have shared library (OMX core + OMX core
wrapper + configuration parser API).
2. we have to record OMX core library in the configuration file in
pvplayer.cfg ( or other file with .cfg extention). Then
pv_omxmastercore loads all omx cores registered in .cfg files while
OMX_Init() is invoked. This pv_omxmastermore is wrapper layer which
helps in loading all cores and their compoents.
3. we can use existing parser node/ parser file. ( as mentioned by
group users )
can we use this without any modification?
my question/ doubt are:
a) what other changes I need to do or which part of the opencore i
have to concentrate, apart from steps mentioned above?
b) I was unable to understand who will invoke parser node?
c) who will call OMX_init().
from my understanding, player will invoke this OMX_Init then
player will be created. is it right?
Thanks
Gururaja
