MPEG-TS and EITs

[Russel Winder]

I am trying to work with the MPEG-TS library using Rust – so no direct C
examples available.

I have a wrapping function:

    pub fn get_eit(&self) -> Option<EIT> {
        unsafe {
            from_glib_none(gst_mpegts_sys::gst_mpegts_section_get_eit(self.to_
glib_none().0))
        }
    }

My problem is that I have sections coming in from the Freeview DVB-T on the
GStreamer bus that report get_name() as "eit" and get_section_type() as
gst_mpegts::SectionType::Eit and yet when applying get_eit() above I get a
None returned. 

This would at first sight appear to indicate that
gst_mpegts_sys::gst_mpegts_section_get_eit is not able to parse some EIT
sections that are being transmitted on Freeview DVB-T, and yet I am really
hesitant to be accept that as a hypothesis.

The C documentation for gst_mpegts_section_get_eit saysit returns NULL if an
error happened. So the question is is it possible for the
gst_mpegts_section_get_eit to correctly find an error in an EIT section
transmitted on Freeview?

I guess I am at a loss as to how to proceed to sort this out, hence this
appeal for assistance.
