Bug #3830
EIT event id decimal conversion mismatch compared to dvbsnoop
0%
Description
Using git master release HTS Tvheadend 4.1-2076~gbb64db6~trusty (25 May 2016) and UK Freeview DVB.
When doing some research I've noticed that eventId from Tvheadend as reported in "http://<IP>:9981/api/epg/events/grid" does not match those reported by dvbsnoop.
For example a eventId in the DVB stream as 0x6af0 is reported as:
dvbsnoop = 27376
Tvheadend = 55281
I'm inclined to think the issue is with Tvheadend because:
a) All eventIds shown by Tvheadend tend to always have a value greater than 55,000 whereas monitoring the event ids from the DVB stream show the full 16-bit range is in use.
b) Google conversion suggests dvbsnoop is correct - https://www.google.co.uk/search?q=0x6af0+in+decimal
Using dvbsnoop 1.4.50 and command "./dvbsnoop -nph 0x12 -f 0x4E -m 0xFF -pd 3"
The only EPG source is epggrab from the DVB stream.
If I've found the correct locations the conversion routines can be found at:

You mix different things. The TVH event ID is totaly different from EIT ID. EIT ID is not exported outside TVH - this values is stored in 'struct epg_broadcast' - dvb_eid member.
