[linux-dvb] dvbsak 0.0.4 released

[Juha Yrjölä <jyrjola@cc.hut.fi>]

After a long silence, here's version 0.0.4 of dvbsak. A _lot_ of things
have been changed.

Here's some noteworthy changes:
      * Autotools support; dvbsak now tries to be a good GNU citizen
      * Channel database; currently only the scconf format is supported
      * dvbrecord program for recording TS streams (PS support is
        coming)
      * EPG decoder
      * Runtime detection of kernel driver API version (ie. NEWSTRUCT or
        oldapi)

The new version is available at:
http://dvbsak.sourceforge.net/dvbsak-0.0.4.tar.gz

And here are some steps to make it work:

$ ./configure --with-dvbdrv-dir=/path/to/DVB
$ make

If all goes well, you should have the programs dvbscan and dvbrecord in
directory src/tools.

$ cd src/tools
$ ./dvbscan --dvb-modulation=64-QAM -S 7146 -s 130M:460M -z 10M --no-center-freq

The above command will scan frequencies from 130 MHz to 460 MHz with a
step-size of 10 MHz. After that you should have a list of transport
streams and services in $HOME/.dvb/channels.conf.

$ ./dvbrecord --zap --whats-on "YLE TV1"

error in dvbts_push_packet(): [00000007] continuity check failed for PID 0x028A (want 15, was 12)

The errors happen when the DVB driver has dropped a packet/packets. For
some reason I get those once in a while. Anyone care to comment on why
this is happening? Holger?

I have tested dvbsak only with DVB-C, so your mileage with DVB-S and
DVB-T might vary. If dvbsak doesn't work for you, patches to fix it will
be greatly appreciated.

Cheers,
Juha
