Re: [Discuss-gnuradio] WARN: transport stream sync error

[Ron Economos]

The BBheader block expects the Transport Stream to start with a sync byte (0x47) and that a sync byte appears every 188 bytes.

There's no sync byte synchronization in the BBheader block, so if the stream doesn't start with a sync byte, you'll get continuous errors.

Hi,

My setup:

Linux gnuradio with dvb-s2 tx sample code. adjusted to read from ZeroMQ pull source

5M symbol. in 8psk dvb-s2 3/4 code rate

Windows side: 2 programs:

1) program to make udpts stream from webcam(5M) -> send udp stream to 127.0.0.1:1234

2) program to listen to udp port 1234 get udp packets and send them to ZeroMQ push socket

gnuradio is complaining about transport stream sync error.

What can be the reason for this?
