Free dvb software for linux

gDVB is a DVB channels manager that allows you to scan different satellites, save your favorite channels list, and view local files.

*NOTE* The 0.5 release is some kind of not-finished monster, so therer non-translated parts. Some semi-implementations and other nasty stuff. Is rather better than 0.4, any volunteer for translations? O:)

Linux::DVB is a Perl interface to (some parts of) the Linux DVB API.

SYNOPSIS

use Linux::DVB;

This module provides an interface to the Linux DVB API. It is a straightforward translation of the C API. You should read the Linux DVB API description to make any sense of this module. It can be found here:

http://www.linuxtv.org/docs/dvbapi/dvbapi.html

All constants from frontend.h and demux.h are exported by their C name and by default.

Noteworthy differences to the C API: unions and sub-structs are usually translated into flat perl hashes, i.e struct.u.qam.symbol_rate becomes $struct->{symbol_rate}.

Noteworthy limitations of this module include: no way to set the frequency or diseqc. No interface to the video, audio and net devices. If you need this functionality bug the author.

dvbcut is a Qt application that allows you to select certain parts of an MPEG transport stream (as received via Digital Video Broadcasting, DVB) and save these parts into a single MPEG output file.
dvbcut follows a "keyhole surgery" approach where the input video and audio data is mostly kept unchanged, and only very few frames at the beginning and/or end of the selected range are re-encoded in order to obtain a valid MPEG file.
dvbcut needs to create index information on an MPEG file first. Therefore, when loading an MPEG transport stream file, it also asks you for a filename of an index file.
If you choose an existing file, it is loaded and used as index if suitable. (That means, that dvbcut performs some sanity checks on the index itself and also checks if the index describes the chosen MPEG file.) If you select a file which does not yet exist, dvbcut creates the necessary index in place.
After opening the MPEG file, you can navigate through the video by means of a linear and a log scale slider. While the first represents the whole video, the latter enables you to precisely select frames close to the current frame.
At any place in the video, you can add START, STOP, CHAPTER and BOOKMARK markers. Markers are shown in the list on the left. With the START and STOP markers you determine what parts of the video you want to write to a new file. dvbcut starts at the first START marker and proceeds until it encounters a STOP marker.
If there are more START markers after that STOP, it will continue at the next START marker, and so on. Every START marker, which follows a START with no STOP inbetween, is meaningless. So is a STOP marker before the first START or after another STOP (with no START inbetween).
dvbcut project supports AC3.
Please be aware, that at the moment, DVBCUT only works with MP2 audio.
Enhancements:
- New upstream version.

tv grab dvb project decodes EPG (electronic program guide) TV listings from DVB (digital video broadcast) and outputs them in XMLTV format.

dvbsnoop project is a DVB / MPEG stream analyzer program, which enables you to watch (live) stream information in human readable form.

Its purpose is to debug, dump or view digital stream information (e.g. digital television broadcasts) send via satellite, cable or terrestrial. Streams can be SI, PES or TS. Basically you can describe dvbsnoop as a "swiss army knife" analyzing program for DVB, MHP, DSM-CC or MPEG - similar to TCP network sniffer programs like the old and famous snoop on Sun Solaris or tcpdump on Linux (which is in fact a kind of a snoop clone). You may also analyze offline mpeg streams, e.g. stored on DVD or mpeg2 movie files.

dvbsnoop is helpful for people interrested in DVB and/or in the technical part of digital television (e.g. if you are a developer of DVB related software). If you are in need to sniff data streams (e.g. tcp/ip, multicasts) send over cable or satellite, dvbsnoop also offers some features and protocol decoding.

In the beginning dvbsnoop was mainly written to learn and understand the DVB protocol structures and streams sent via satellites. Out of this reason, the program ist not highly performance optimized, but it hopefully will do its job. Have a look on the feature list, what dvbsnoop is capable of and what it can do for you...

Dvbsnoop is still under development and will be enhanced in the future (depending on my spare time). Ideas, bug reports, enhancements are welcome. Dvbsnoop is currently part of the tuxbox project and is designed to run on unix based set top boxes, too.

dvbsnoop is based on the linux dvb api. You need the dvb driver installed on your computer to use dvbsnoop. dvbsnoop is text-based, so it should work on any unix based system, which offers shell access and dvb support installed.

dvbsnoop is a commandline tool.
To tune in a transponder, use a proper tuning program like dvbtune.

dvbsnoop [options] pid

pid can be any unsigned number within the legal pid number range.
The PID can be specified in hex, octal or decimal version (using C-syntax -notation).
e.g.: hex: 0x1A, octal: 0722 , decimal: 6932

dvbsnoop tries to decode every data it gets....
E.g. if you try to decode a video or audio stream in section mode - dvbsnoop may assume a section table and will decode wrong data. In this case the decoding will be garbage! Using the -crc option should prevent this (if supported at hardware/driver level). Also the -sync option is very helpful, when using -s pes or -s ts. The -sync option tries to find TS or PES packet start sync bytes before decoding...

dvbsnoop doesnt do DVB stream validation....
dvbsnoop assumes correct dvb streams. Getting garbage, corrupted streams or streams with wrong semantics (e.g. incorrect length information) will result in wrong decoding output. Because od this, the usage of the options -crc and -sync is strongly recommended!!

Bugs and wrong decoding:
If you see any odd output, please report this.
Wrong decoding can be mostly avoided, using the options -crc and -sync.

python-dvb3 is Python bindings for the Linux DVB v3 API.

DVB Remote Key Editor project was made in order to have an easy way of modifying the keymaps of DVB-T remotes which are usually hardcoded in the corresponding kernel-modules.

Currently this works for the following models:

Haupauge Win-TV Nova-T USB2 dvb-usb-nova-t-usb2.ko 45
Cinergy T2 cinergyT2.ko 37
AVerMedia AverTV DVB-T dvb-usb-a800.ko 34
Generic dib-usb Driver dvb-usb-dibusb-common.ko 63
WideView/Yakumo/Hama/Typhoon/Yuan DVB-T USB2 dvb-usb-dtt200u.ko 18
TwinhanDTV Alpha/MagicBoxII USB2 dvb-usb-vp7045.ko 32

This will not work if your kernel is enabled to use ksign, which secures kernel-modules against binary modifications.

Usage:

Run as root by executing: gksudo python dvb-remote-key-editor.py

Warning: This application binary patches a kernel module. Therefore be sure to make a backup of the module. THIS SOFTWARE COMES WITH ABSOLUTELY NO WARRANTY!

Kvdr program lets you watch the output of VDR on a monitor in X11.
Main features:
- anything vdr can do and will do
- handles the overlay of your dvb-cards
- lets you zap through your video devices or display up to for overlays at once (if you have more than one card). However - changing the channel via vdr is currently only supported on the "primary" dvb-interface.
- The picture in picture allows you to follow the movie at the other device in the small image. You can exchange those by a single key-press.
- the Xv-mode lets you zoom the image to larger resolutions and optionally handles deinterlacing by 50Hz half frame upscaling or field1 upscaling.
- fullscreen-mode (mouse, dpms and screensaver automatically handled)
- can be used for "remote" viewing of vdr-recordings if you have 2 dvb-cards and the remote-video-directory mounted
- lets you grab images during viewing, playback or recording in jpg or pnm format, filename is automatically generated out of channel-name, date and time.
- lets you control Brightness, Colour, Hue and Contrast of the overlay (not applied to grab-images!)
- handles 4:3 and 16:9 aspect ratios corrected with viewport-dimensions (currently at 4:3 monitors only)
- handles PAL and NTSC accordingly (but only PAL tested so far - iam living in Germany ;-)
- stores all configuration to file
- sound-handling: mixer-channel, volume and mute using alsa/amixer
- Front/Rear-volume balance
