I think there's a bug in scan.c. From the CVS version,
I get multiple audio pids for certain services, e.g.
OPT - ABC PNN:12720:v:S156.0E:30000:0:776,776,776:0:1:833:0:0:0
I think this is caused by the same table id being used for different
service id's.
Truncated trace shows following services: (extra debugging is mine)
parse_section:920: pid 0x00 tid 0x00 table_id_ext 0x0008, 0/0 (version 4)
PAT
service 0x0341
allocate 0x0341
pid 0x0022 priv 0
add_filter:1125: add filter pid 0x0022
start_filter:1071: start filter pid 0x0022 table_id 0x02
service 0x0342
allocate 0x0342
pid 0x0022 priv 0
add_filter:1125: add filter pid 0x0022
start_filter:1071: start filter pid 0x0022 table_id 0x02
(many more services detected)
So multiple filters are set up for the same table id.
When the filters are read back, there are then multiple audio
pids assigned.
read_filters:1165: filter done pid 0x0022
remove_filter:1133: remove filter pid 0x0022
stop_filter:1111: stop filter pid 0x0022
