It seems this test is for multiplexing x-h264 video and mpeg audio into MPEG-
TS packets. Useful test, but not entirely useful in my current situation.
My problem is needing to test EIT messages. From what I can tell in gst-
plugin-bad there is lots of code for dealing with EIT packets. It seems that
tests/check/libs/mpegts.c tests for individual manually created PAT, PMT, NIT,
SDT, and STT packets, but no EIT packets. It appears there are no tests for
the EIT handling code in GStreamer, but I guess a detailed coverage report is
needed to prove/disprove this claim.
Whilst tests/examples/mpegts/ts-parser.c is likely great for debugging EIT
messages in a GStreamer pipeline, it assumes generation of the EIT packet
elsewhere, and it assumes a pipeline.
I am getting close to writing a program to generate valid and invalid EIT
packets with various numbers of EITEvents. I suspect D might be a better
language to write this in than Rust – I am very unlikely to use C and I really
don't want to go back to C++.
