[mythtv] DVB CI

Seems that your prognum is what vdr calls service id.
I wasn't loading this. Like I wasn't transponder id and netword id.
Do you think I should?

HI!


Have to agree with you that syncing is a problem here, at least when you mix
and match patches :) On the other hand, code that gets committed to CVS
should have a somewhat sane state, which this patch is yet to have.

As to the prognum field, let me explain some:
1. Tune to any transponder.
2. Read pid 0x0, and you get a map between prognum -> another pid
3. Read 'another pid' and you get a map of the stream,
    audio/video/subtitles.....
4. To decode a channel the CAM needs the map in 3 / prognum / pids.

Sorry about not including any mysql update stuff, slipped my mind. Anyways,
nobody seems to have dared testing it yet (does someone else even have a
card with CAM here?)

Have also had some trouble changing between channels (encrypted, the fta are
fine), same trouble as before I think: For some strange reason the video
AVCodec seems to (sometimes), either to be set to NULL or deleted completly.
Anyone have any hints on this? (Sometimes the codec dumps a lot of errors,
and finally segfault somewhere along the decoding chain)

Seems like there is some bad data (encrypted?) around channel change.

mmmm, although is still in development, maybe because of that, I think that
we have to upload this this to CVS, my developments have also a few changes
to some of those files, I'm also implementing the split of pids to
vpids/apids (audio/video) as Ben suggested....It's really a headache to
maintain this synched having simultaneous developments in progress. Is that
something that can affect to the rest of mythtv?

btw, what's the expected content of new column prognum? Is that for CI,
i.e., col #9 (starting from 1) in channels.conf file? If it is and you use
the same code, I had already uploaded that into channel_dvb in the
providerid column.

Ramon.

Hi All DVB Fans:)!


Here's my patch for (working? works for me) CI, now that the required lib is
in CVS.

Now, this is not intended as a candidate for CVS as of yet (If you have time
Isaac, there are some parts that might be interresting).

Have fun!
