Support for capturing MPEG-TS with Linux DVB #330
Conversation
Code based on dvbtraffic util from dvb-apps under public domain
Most likely because Travis haven't done autoreconf, and I didn't submit generated (configure, config.h.in) files. |

This looks fun. It looks like it requires some dvb libraries to be loaded; can you add those to travis.yml? |
I'm not seeing any special DVB library calls - are you sure they're there?
Yes, please rebase this. |
Please submit them, even though they're generated files. |

There was a problem hiding this comment.
Presumably you mean "DVB", not "netfilter".

This code is still welcome, if you'd like to rebase. |

This is the longest standing pull request in this project. @darkjames, if you would like to revive this contribution, please comment within 7 days. Otherwise it will be closed. |

@darkjames I turned the change into a patch, applied it to the tip of the main branch, fixed the two cases of "netfilter" instead of "DVB" in comments, brought it up to date with changes made to libpcap since 2013, and added CMake support. It appears to compile; I have no DVB hardware with which to test it (nor a physical Linux box into which to plug that hardware, and I live in ATSCland anyway, so I'm not sure I could capture any traffic with a physical Linux box with DVB hardware). Is this still of interest? I'll ask on tcpdump-workers, wireshark-users, and wireshark-dev as well. |

I have a USB device that has some DVB receiving capability, but not the aerial; also it is not clear whether the device can receive the terrestrial DVB that is said to be available around here, and whether it is what the proposed change implements. This patch would be much easier to test if there was someone with a working Linux DVB setup who could try the patch and tell how it works. |
|
I asked around on IRC, but have not found a volunteer equipped with the right props. If you were going to ask on the mailing lists, please do. |
|
Current status: I managed to find a way to test the patch with DVB-T signal, Guy has the test results. |
|
Whilst this remains a work in progress, let's give credit where credit is due. Testing of the proposed patch (rebased by Guy Harris) happened thanks to various help provided by Stewart Williamson, a fine Scotsman and a cyclist, a former racer of the Musselburgh Roads Cycling Club. |
|
The current work in progress rebased on the current master branch (after the recent DPDK changes) is in the "GHPR330-DVB" branch in the "libpcap-incomplete-works" repository. |
Initial support for capturing MPEG-TS with Linux DVB API.
it capture all PIDs and you must manually tune before capturing.
