Refactor virtual EIT generation somewhat #1088

don't write a full TS packet, use buffer_to_ts like for our other tables
move CC counter to the adapter
don't add EIT for the non-existant SID returned by MAKE_SID_FOR_CA(), only add for the SIDs we actually have in the transport stream

catalinii commented 1 year ago

The reason MAKE_SID_FOR_CA was used in the first place is that is possible to decrypt the same channel from 2 separate adapters, or in case of a sid clash.

Jalle19 commented 1 year ago

I'll need to think about that scenario for a bit

Jalle19 commented 1 year ago

The SID given to ddci_create_eit() comes from the PMT, so to me it seems that it's not possible for there to be any other SIDs in the stream. If two PMTs have the same SID then that's okay, the EIT is identical for all services anyway.
