PMT decoder: invalid section

user will see many such messages on some sources - like terrestrial ts

ts error: libdvbpsi (PMT decoder): invalid section (table_id == 0x00 expected 0x02)

sample-2.ts in this sample

table_id == 0xc?

it is also not possible to disable those messages in gdb output...(in that case slow video playback)

maybe it would be good idea to suppress same messages in output?

François might know.

no errors in 2.1.5

       direct3d9 debug: Reusing 95x31 texture for OSD
[x100] ts error: libdvbpsi (PMT decoder): invalid section (table_id == 0x00 expected 0x02) 
       direct3d9 debug: Reusing 95x31 texture for OSD

this could apply for other repeating messages

That's discontinuity in dvbpsi decoder. Sequence skips sections.

in any case, for any repeating messages it would be good idea to compare and count such as:

direct3d9 debug: Reusing 95x31 texture for OSD
ts error: libdvbpsi (PMT decoder): invalid section (table_id == 0x00 expected 0x02) 
info      previous message suppressed x times

ATSC tables transmitted on the same pid

libdvbpsi can't handle other tables carried on the same psi pid. It is discarded.

Other tables are legit, except for CA (pid 0x1). That error should not happen.

These are false positive. libdvbpsi has been patched for outputting only as debug info. (unless it is extented to handle private tables)
