Patch to allow dvbstream to access 8 devices

2009-02-18T03:15:40Z

The version of dvbstream bundled in debian etch/lenny can only handle up to 4 dvb devices. For stability in my mythtv system, I have created higher artificial links/devices via udev, such as 5,6,7.

The attached patch allows dvbstream to access up to 8 devices, to allow access to the linked devices.

fix handling of -n parameter

2006-08-03T13:00:56Z

Although dvbstream accepts the -n parameter on the
command line to set the number of seconds to record, it
does not handle the value set, or in other words does
not stop recording after the elapsed time.

This patch fixes this bug and dvbstream will cleanly
stop recording after the number of seconds set with -n
have elapsed.

DVB-T Germany defaults 2nd

2006-05-07T17:24:16Z

As it seems that I do not understand how to submit
files in SF.net I put the code to the descr.
Here it is and it has to go to the dvb_defaults.h:

#ifdef GERMANY

/* GERMANY settings */
#define DVB_T_LOCATION "in Germany"
#define BANDWIDTH_DEFAULT BANDWIDTH_8_MHZ
#define HP_CODERATE_DEFAULT FEC_1_2
#define CONSTELLATION_DEFAULT QAM_16
#define TRANSMISSION_MODE_DEFAULT
TRANSMISSION_MODE_8K
#define GUARD_INTERVAL_DEFAULT
GUARD_INTERVAL_1_4
#define HIERARCHY_DEFAULT HIERARCHY_NONE

#endif

Thank you,

DVT-T defaults for Germany

2006-05-07T17:18:41Z

Find the defaults for DVB-T in Germany in the
attached file.
To the Makefile these lines have to be added then:

ifdef GERMANY
CFLAGS += -DGERMANY
endif

By the way:
Thank you for the great tool!

Fix dvbstream DVB-C tuning for CVS version

2005-12-18T15:11:05Z

In tune.c, the QAM tuning parameter INVERSION_OFF
causes tuning to fail (Cinergy 1200 DVB-C budget card,
linux 2.6.12, HTV cable network in Finland).

The error shown is:
Not able to lock to the signal on the given frequency

Changing it to obey the command line parameter -I fixes
the problem (The default INVERSION_AUTO works fine for me).

dvbstream/tune.c line 272

- feparams.inversion=INVERSION_OFF;
+ feparams.inversion=specInv;

Quite obviously this applies to dvbtune/tune.c as well.

As a different matter, the 0.5 release enters an
infinite polling loop as described eralier by someone
else. This problem doesn't exist in the CVS version.

The attached is necessary to produce a useful XML file in the UK using dvbtune -i since TUTV started (missing trailing slash).

patch for reasonable Australian defaults

2003-07-18T16:38:20Z

We finally have a card here that supports our mostly VHF
DVB-T. I have attached a patch with a reasonable set of
defaults for dvbstream (would work on dvbtune as well) for
Australia using the same method as already in place for
Finland ("make AUSTRALIA=1").

Not all the stations use the same values for guard interval
and code rate so I've picked the ones used by the majority.
In my experience it doesn't make any difference what these
are set to anyway, the main thing is to get the bandwidth
right and all stations are on 7 MHz channels.

Thanks for a great piece of software it works out of the box.

PMT parsing patch for dvbtune.c

2002-05-29T02:15:45Z

dvbtune only works correctly if there is a unique PMT
PID for each program definition.

The attached patch fixes the scan_pmt(int pid,int
sid,int change) functions, so that it only parses the
current PMT section which matches the service_id (i.e
program_number) as specified by the "sid" argument.

With the patch, satellite transponders which only use
one PMT PID for every program definition now work
correctly with dvbtune.
