I wrote several patches those days in order to allow dvb-apps to properly
parse ISDB-T channel.conf.
On ISDB-T, there are several new parameters, so the parsing is more complex
than all the other currently supported video standards.
I've added the changes at:
http://linuxtv.org/hg/~mchehab/dvb-apps-isdbt/
I've merged there Patrick's dvb-apps-isdbt tree.
While there, I fixed a few bugs I noticed on the parser and converted it
to work with the DVB API v5 headers that are bundled together with dvb-apps.
This helps to avoid adding lots of extra #if DVB_ABI_VERSION tests. The ones
there can now be removed.
TODO:
=====
The new ISDB-T parameters are parsed, but I haven't add yet a code to make
them to be used;
There are 3 optional parameters with ISDB-T, related to 1seg/3seg: the
segment parameters. Currently, the parser will fail if those parameters are
found.
gnutv is still reporting ISDB-T as "DVB-T".
I've just fixed the issues on the TODO list. The DVB v5 code is now working fine
for ISDB-T.
Pending stuff (patches are welcome):
- Implement v5 calls for other video standards;
- Remove the duplicated DVBv5 code on /util/scan/scan.c (the code for
calling
DVBv5 is now at /lib/libdvbapi/v5api.c);
- Test/use the functions to retrieve values via DVBv5 API. The function
is
already there, but I haven't tested.
With the DVBv5 API implementation, zap is now working properly with ISDB-T.
gnutv also works (although some outputs - like decoder - may need some changes,
in
order to work with mpeg4/AAC video/audio codecs).
Very good job!
Have you had a look here on this one
http://www.mail-archive.com/v...@linuxtv.org/msg11125.html
?
I had this on my list because I wanted to spent some time on DVB-S2 myself
and it seemed to be a good step to merge it (back) into dvb-apps. Though I
haven't yet looked at it in detail.
I will check your changes soon, but after the holidays.
So, now you should have some quiet time for yourself! ;-)
