dvbsnoop - an open source DVB/MPEG stream analyzer ==================================================== https://github.com/OpenVisionE2/dvbsnoop https://github.com/OpenMipsel/tuxbox-cvs dvbsnoop is a DVB/MPEG stream analyzer program. The program can be used to sniff, monitor, debug, dump or view DVB/MPEG/DSM-CC/MHP stream information (digital television or data broadcasts) sent via satellite, cable or terrestrial. The program was mainly written to learn and understand the DVB protocol structures and streams. dvbsnoop is currently part of the tuxbox project, bringing Linux based TV software to some set top boxes (digital satellite/cable receivers). Documentation and example outputs can be found at: https://github.com/OpenVisionE2/dvbsnoop Disclaimer: =========== You are using this program at your own risk!

But it was tested on GCC (gcc-3.x) only. If you see any problems during 'autoconf.sh' or 'configure' execution, please check if you have the latest versions of 'autoconf' and 'configure' installed. In cases, please update your system (check packages automake, autoconf and libtool). Please see also mini FAQ at the end of this file. - Special Platforms Cygwin: dvbsnoop may be used on Microsoft Windows Platforms using cygwin (http://www.cygwin.com). Due to a missing dvb hardware layer you may use dvbsnoop in offline mode only. To compile dvbsnoop for cygwin, please read annex "cygwin". Posting dvbsnoop output: ======================== If you are posting dvbsnoop output to mailing lists, newsgroups, public boards or whatever, please always include the dvbsnoop header: e.g.: " dvbsnoop V1.2.49 -- https://github.com/OpenVisionE2/dvbsnoop" The version information is helpful if there are discussions about the decoding output. Using source code snippets or dvbsnoop knowledge for your own purpose: ====================================================================== Feel free to use dvbsnoop source for your own programs as knowledge or code base. In any cases, please include a link or reference to dvbsnoop in your program or documentation... Thanks. Bugs, requests: =============== Well, if you find some bugs, please let me know. (check first, if the data stream is not broken). Reoport bugs to: http://sourceforge.net/tracker/?group_id=85040 Please do not send binary data stream files or large decoding output via email! (If needed, I will ask for it!) But it is a good advise to save the data stream using the option "dvbsnoop -s ... -b ... > file" on your harddrive. It might be helpful for further investigations.

Tnx to Kamal for this description: -----Original Message----- From: Kamalanand [mailto:kamal_dasu@xxxxxxxxxx] Subject: RE: dvbsnoop as analyzer on Windows - worked Rainer, I had to apply a few fixes in my environment to make dvbsnoop build with cygwin. This might be very specific to my environment, however wanted to share this with you if others face a similar problem. I am using the following cygwin version downloaded using setup.exe on http://wwww.cygwin.com : CYGWIN_NT-5.1 my-pc 1.5.18(0.132/4/2) 2005-07-02 20:30 i686 unknown unknown Cygwin I have the following installed in the cygwin environment 1) Dvbsnoop https://github.com/OpenVisionE2/dvbsnoop under ~/dvbsnoop-1.4.00/ 2) Downloaded the linux kernel 2.6.12 sources from http://www.kernel.org/ , extracted to /linux-2.6 These are the things I did to have a successful build, 1) Copied the dvb includes from the /linux-2.6/include/linux/dvb under /usr/include/linux/dvb (Actaully I made a symbolic link but its upto you.) 2) The cygwin installation had the __u64 type missing in the /usr/include/asm/types.h , So added that to /usr/include/asm/types.h. This is needed by the struct dmx_stc in /usr/include/lnux/dvb/dmx.h .. typedef __signed__ int __s64; typedef unsigned int __u64; .. 3) Then noticed the dmx_pes.c includes file_io.h which includes the sys/ioctl.h. I figured that the IOCTL macros are needed to compile ~/dvbsnoop-1.4.0.0/src/dvb_api/dmx_pes.c file. The IOCTL macros are used in the /usr/include/linux/dvb/dmx.h which get called in the dmx_pes.c. Now cygwin /usr/include/sys/ioctl.h does not have the macros in it and /usr/include/asm/ioctl.h is missing in the cygwin environment for some reason. Anyway I copied the /include/linux/asm-i386/ioctl.h from linux kernel sources to the /usr/include/asm/ioctl.h . Then added the following to the /usr/include/sys/ioctl.h #include <asm/ioctl.h> 4) However the ~/dvbsnoop-1.4.0.0/src/misc/packet_mem.c refused to compile due to various type incopatabilities with strings.h and stdlib.h under cygwin. Basically it needed the definitions for u_char and u_long. So I tried the following to fix the problem : /* #include <string.h> */ /* #include <stdlib.h> */ #include <sys/types.h> Maybe there is a better way to do this, for now this seemed to work for me 5) Ran the following ~/dvbsnoop-1.4.0.0/configure script ~/dvbsnoop-1.4.0.0/make clean ~/dvbsnoop-1.4.0.0/make ~/dvbsnoop-1.4.0.0/make install Now I am able to do offline analysis and decode the MPEG streams. Thanks & Regards Kamal dvbsnoop > version 1.4.0: ========================== To make dvbsnoop run on cygwin platforms, you have to: 1.) copy dvb-api include files to your cygwin installation. 2.) maybe: you have tweak some cygwin header files. 3.) see src/dvb_api/dvb_api.h: uncomment the IOCTL, etc. #defines (please read remark in header file) 4.) Next: go on with standard procedure...: ./configure make etc. if you encounter some problems, try "make distclean" prior to autogen.sh Problems compiling dvbsnoop? ============================ Mini-FAQ from the tuxbox project (linux@dbox2): Q: Why is there no configure script? A: "autoconf" creates configure from "configure.ac". You can call "./autogen.sh", which will call "autoconf" for you. Q: Why is there no "Makefile", neither in the root directory nor in any subdirectory? A: "configure" creates "Makefile" from "Makefile.in". "./configure --help" usually shows the available options. Q: Why is there no "Makefile.in"? A: "automake" creates "Makefile.in" from "Makefile.am". You can call "./autogen.sh", which will call "automake" for you. If you call "automake" manually, then make sure your working directory contains "configure.ac".
