Hi list,
Based on the original DVB API patch of last week, I've done a cleaner
rewrite of the patch. This time, the changes to the VDR sources are
limited to a few #includes and replacements of ioctl calls by the new
DVBFE_ioctl wrapper call. All the magic goes into this API wrapper, that
translates multiproto calls into DVB 3.0 API calls.
There's also more control on the behavior. Adding DEFINES +=
-DDVB_MULTIPROTO_WRAPPER=1 to Make.config will enforce the API
translation even if the multiproto API is present, setting it =0 will
disable API translation, requiring the multiproto API to be present. By
default, the present API is automatically detected, and the wrapper is
enabled accordingly.
The patch currently doesn't translate the whole API, just the parts that
are used by VDR. But if required, the missing parts can surely be
integrated.
Cheers,
Udo
