JSON output... isnt?

[benjojo]

I fed in a day or so of BBC Radio 1's TS mux into this like so:

cat /dvb/6720/365/14515*.ts | ./dvbtee/dvbtee -j |& tail -n 120 (tailing because I can't find a way to turn off the dots)

And got at the end of it:

This is accurate (other than lengthSec and startTime, those don't seem to make sense, or I'm missing something completely) however the output given here is not JSON that can be read. Mainly because of the single quotes, this makes automating the use of this program tedious

[mkrufky]

Good point about the single quotes - I just changed them to double quotes and pushed to master. As for the lengthSec and startTime, these are just the raw fields in the PSIP tables - they need some manipulation to convert to human readable timestamps. The high 16 bits are coded as Modified Julian Date (MJD) and the low 24 bits are coded as 6 digits in 4-bit Binary Coded Decimal (BCD). Does the debug output on the console for that EPG event have the right time?

Are you talking about the periods that draw when there is a TEI error in the TS?

Are you talking about the periods that draw when there is a TEI error in the TS?

Most likely yes, I tried reading around, is there a way to disable those?

There wasn't before today, but I just added a compile flag to disable them, along with the TEI message on stderr. I'll probably change it to a runtime flag, or maybe switch it to default... let me think on that a bit, but this should resolve it for you in the meanwhile.

Please update your sources with the latest changes in my master branch and rebuild passing CXXFLAGS=-DQUIET_TEI to ./configure. For example:

./configure CXXFLAGS=-DQUIET_TEI

or if you're using build-auto.sh, you can pass it there:

./build-auto.sh CXXFLAGS=-DQUIET_TEI

Yup, This all works for me now, Thanks for the help!
