When I implemented PSIP-scanning to dvbscan I looked for a libsi to use
for section parsing, but I didn't find anything useful. I wrote something
for myself for scan (see atsc_psip_section* in utils/scan). In fact it is
a perl-script which generates c and header-files to have easy and
transparent access (no bitshifting and -masking in scancode) to
section-structures in scan. The current version lacks reading
variable-length string-fields, but I think this is solvable (libsi should
do the memory-management).
Parsing the section in the application looks like this:
struct ATSC_service_location_element e = read_ATSC_service_location_element(b);
accessing it:
switch (e.stream_type) {
case 0x02: /* video */
s->video_pid = e.elementary_PID;
and so on.
What do you think? Could this be a way to go on for SI?
