I decided to do some tests using kernel 2.6.13.3, with following results:
1) locking problems occur using "dvbscan -v" (nut also ("vlc -v") in the
following situations:
=> 2.6.13.3 kernel with downloaded snapshot 20051202: locks fine,
dvb-scan returns 0x1f and dumps PMT quickly
=> 2.6.13.3 kernel with downloaded snapshot 20060115: locks fine,
dvb-scan returns 0x1f and dumps PMT quickly
=> 2.6.13.3 kernel with downloaded snapshot 20060715: no lock, dvb-scan
returns 0x00 + timeout!
=> 2.6.13.3 kernel with downloaded snapshot 20060717: no lock, dvb-scan
returns 0x00 + timeout!
=> 2.6.13.3 kernel with downloaded hg snapshot: no lock, dvb-scan
returns 0x00 + timeout!
So it seems that something has gone wrong between snapshots from January
and July, with these locking problems as a result.
The strange thing is that the locking problems do not prevent xine or
vlc from coming up with streaming data (picture), however in between
"vlc -v" prints 'no lock' every 15 seconds or so, but keeps going anyway
....
Of course I would prefer to use the latest dvb-version, but I cannot get
it to work for reasons mentioned above.
What could possibly be wrong?
Can someone tell me who has a more recent working combination (recent
kernel + recent dvb-snapshot)?
2) in all dvb-snapshot versions that have I tested, I always need to
remove the DST_TYPE_HAS_TS204 flag from the "DCT-CI" record in dst_list
(dst.c), or I will not get a picture; only a long list of TS
discontinuities. Aren't the necessary patches (Sept 2005) present in
recent snapshots? I don't understand why I keep running into this
problem ....
In the latest v4l-dvb HEAD if you have the TS204 flag, it fixes your
problems ?
To check once more, I have just setup once again:
=> linux-2.6.17.8
=> hg v4l-dvb (fresh clone of today)
At a fresh 'make' on v4l-dvb, I do get several warnings about missing
kernel configuration flags, but it seems that I can ignore those, as
none of those seems to affect my configuration.
The output of dvbscan -v is:
tune to: 306750000:INVERSION_AUTO:6900000:FEC_NONE:QAM_64

... and no PMTs get reported.
Also vlc complains that 'dvb access warning: no lock, tuning again'
every 20 seconds or so.
Unfortunately I cannot test 20060115's snapshot against linux-2.6.17.8
because the MODULE_PARM macro is no longer supported in 2.6.17 and I get
a compile error.
But if I compile with linux-2.6.13.3:
=> vlc-dvb-20060115 works (provided I take out TS204 from DCT-CI record)
=> vlc-dvb hg clone does not work.
So something seems to be broken...
Z.
