1.8 holger 1: Instructions for building the standalone driver:
2: ------------------------------------------------
1.1 hunold 3:
1.9.2.2 holger 4: If you encounter any problems while executing the follwing steps please read
5: the TROUBLESHOOTING file.
6:
7: Simply type 'make' to build the driver. The compiled modules will be located
1.9.2.4 holger 8: in directory ./build-2.4/ or ./build-2.6/, depening on the kernel version you
1.8 holger 9: are running. There you will also find scripts to load and unload the modules.
10:
11: For some cards you need to download additional firmware binaries. You get
12: notified in the build process or when loading the modules, please follow the
13: instructions there if you own one of the cards that need a firmware to run.
14:
1.9.2.1 holger 15: Be sure that you are root for the following steps.
16:
1.8 holger 17: Now execute the ./MAKEDEV-DVB.sh script to create the DVB API device nodes.
1.9.2.1 holger 18:
19: In ./build-2.4/ or ./build-2.6/ you find the insmod script.
20:
1.9 holger 21: Use './insmod.sh load' to load the driver modules, './insmod.sh unload' to
22: remove them. './insmod debug' loads the drivers with debugging enabled.
1.9.2.6 ! holger 23: These scripts load all drivers for all cards but the ones based on the bt8xx.
! 24: For bt8xx based cards please use the insmod-bt8xx.sh script instead.
1.9.2.1 holger 25:
1.9.2.5 holger 26: Now check the klog and syslog (in doubt type 'dmesg') for error messages.
1.9 holger 27:
1.8 holger 28: When you reached this point successfully you probably want to start some
29: test applications, download the linuxtv-dvb-apps-1.1.tar.gz package, unpack
30: it and compile it. This package contains some tools to test and debug the
31: driver:
32:
1.9 holger 33: linuxtv-dvb-apps-1.1/apps/szap/ contains three simple applications called
34: szap, czap and tzap for zapping with DVB-S, DVB-C or DVB-T cards.
35: Read linuxtv-dvb-apps-1.1/apps/szap/ README for usage instructions.
1.8 holger 36:
37: Note 1: tuning succeeded if you see the FE_HAS_LOCK flag and "status 1f"; a
38: good signal has a low bit error rate (ber) and zero uncorrectable packets (unc).
39:
40: Note 2: you must keep ?zap running, or the frontend will go to sleep (unless
41: you load dvb-core.o with dvb_shutdown_timeout=0)
42:
43: If your card has a hardware MPEG decoder you can watch TV with xawtv (together
44: with e.g. szap for DVB tuning); Note: xawtv cannot control the DVB tuner, you
45: must use ?zap
46:
47: For cards without hardware MPEG decoder you need a software MPEG decoder,
48: e.g. mplayer or xine (you need *very* recent versions which understand MPEG2
49: transport streams; xine v0.9.21 and mplayer dev-CVS-030723-16:39-3.3.1 seem to
50: work); Note: You must run ?zap with the -r flag to enable stream output to the
51: dvr device, and keep it running while watching tv.
52:
53: Examples:
54: mplayer - < /dev/dvb/adapter0/dvr0
55: xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0
56:
57: Note: Newest mplayer and xine versions are reported to have builtin DVB support
1.9 holger 58: (see ./linux/Documentation/dvb/faq.txt for more info).
1.8 holger 59:
60: For 'real' everyday use you probably don't want to use these test applications
1.9 holger 61: but install a program like VDR or MythTV.
62: (Read ./linux/Documentation/dvb/faq.txt for some links)
1.8 holger 63:
1.9.2.3 holger 64: When everything is working you probably want to install the driver on your
65: system by typing 'make install'. If you want to load the modules automatically
66: when an application tries to open the device you need to add lines like these
67: to your modules.conf:
68:
69: probeall /dev/dvb dvb-ttpci
70: alias /dev/dvb/* /dev/dvb
71: below dvb-ttpci alps_bsrv2 alps_tdmb7 alps_tdlb7
72: add below dvb-ttpci grundig_29504-401 grundig_29504-491
73: add below dvb-ttpci stv0299 ves1820
74:
75: Note: this example is for people with Technotrend-based PCI cards, they must
76: load the dvb-ttpci driver and a matching frontend drivers that are potentially
77: used on these cards. In order to find out which ones are required for your
78: setup check the lsmod output after loading the driver like described above.
79: Those DVB modules that have a usecount greater zero are required in your
80: setup - edit the modules.conf file appropriatly]
81:
82: Debian users don't edit modules.conf manually but add the lines above to a new
83: file in /etc/modutils/ (e.g. /etc/modutils/dvb) and call 'update-modules' then.
84:
1.8 holger 85: --------------------------------------------------------------------------------
86:
87: The build system has been tested down to 2.4.20, if you run an older kernel
88: either update your kernel or just try - maybe you need to add some tweaks in
89: the dvb_compat.[hc] files. Please report your modifications on the linux-dvb
90: mailing list.
91:
92: If you want to build a not-standalone driver but want to patch your 2.6 kernel
93: source tree with this driver please read README-2.6.
94:
95: More documentation is located in ./linux/Documentation/dvb/.
96:
97: good luck,
98:
