[dvblast-devel] [biTStream] Issue invalid_sdt_section

[Kristof Meersseman]

Thank you Ludovic,

I have managed to capture the EIT table data, but I have no service id's... In that way I don't know which service the event corresponds to.
I do it this way : multicat -u -p -S -X @239.0.1.3:49152 test3.ts | ts_filter 18 | ./dvb_print_si -x xml -T EIT > test_arte.xml

When I look with TS reader I see the service id's, so they are actually there ...

This is the output:
<?xml version="1.0" encoding="utf-8"?>
<TS>
<EIT tableid="0x53" type="actual_schedule" version="7" current_next="1" tsid="1051" onid="1" seg_last_sec_number="120" last_table_id="0x56">

Hello Kristof,

I'm pretty sure your flow is UDP but not RTP, so it can't work. Here is a exemple with an UDP stream:
# dumprtp 239.255.2.1 1234| ts_filter 18| ./dvb_print_si -x xml -T EIT <?xml version="1.0" encoding="utf-8"?> <TS> Filtering pid 18 Rtp dump FATAL ERROR IN STREAM AT PACKET 1 FATAL ERROR IN STREAM AT PACKET 2 FATAL ERROR IN STREAM AT PACKET 3 FATAL ERROR IN STREAM AT PACKET 4 FATAL ERROR IN STREAM AT PACKET 5 FATAL ERROR IN STREAM AT PACKET 6
rtptsaudio: NETWORK CONGESTION - expected 30752, received 30740
rtptsaudio: NETWORK CONGESTION - expected 30741, received 30746

You can try with dvbsnoop tool:
# dumprtp 239.255.2.4 1234 | ts_filter 17|dvbsnoop -nph 0x12 dvbsnoop V1.4.50 -- http://dvbsnoop.sourceforge.net/ Filtering pid 17 Rtp dump
