Free video teletextdb software for linux

Video::TeletextDB is Perl extension to manage a telextext database.

SYNOPSIS

use Video::TeletextDB;

$tele_db = Video::TeletextDB->new(%options);
# Possible options are:
# cache_dir => $directory
# mkpath => $boolean
# umask => $mask
# creat => $boolean
# RW => $boolean
# page_versions => $number
# channel => $string
# stale_period => $seconds
# expire_period => $seconds

$access = $tele_db->access(%options);
# Possible options are:
# umask => $mask
# creat => $boolean
# RW => $boolean
# page_versions => $number
# channel => $string
# stale_period => $seconds
# expire_period => $seconds

$cache_dir = $tele_db->cache_dir;
$channel = $tele_db->channel;
$old_channel = $tele_db->channel($new_channel);
@channels = $tele_db->channels;
$nr_channels = $tele_db->channels;
$boolean = $tele_db->has_channel(?$channel?);
$db_file = $tele_db->db_file;
$lock_file = $tele_db->lock_file;
$tele_db->lock;
$page_versions= $tele_db->page_versions;
$umask = $tele_db->umask;
$old_umask = $tele_db->umask($new_umask);
$RW = $tele_db->RW;
$old_RW = $tele_db->RW($new_RW);
$stale_period = $tele_db->stale_period;
$old_stale_period = $tele_db->stale_period($new_stale_period);
$expire_period = $tele_db->expire_period;
$old_expire_period = $tele_db->expire_period($new_expire_period);
$user_data = $tele_db->user_data;
$old_user_data= $tele_db->user_data($new_user_data);

$tele_db->delete(%options);

The idea behind a teletext database is to separate the process of collecting teletext pages from the process of presentation. This makes programs both shorter (you dont have to implement the side yourre not interested in) and more flexible (you can read teletext pages long after the collector stopped running and you dont have to be tuned in to the channel you want to read).

In fact, the simple script TeleCollect coming with this package will be good enough for most teletext collection purposes, so that you can concentrate on the page processing.

This modules provides you with methods to both store and retrieve pages into a database and some rudimentary support to manage a set of databases (typically one for each channel). The pages will be stored in raw form so that a client can decide for itself how to handle things like transmission errors (there are of suggested methods provided in the module though, so you dont have to reinvent the wheel every time).

It (currently) use a Berkeley DB with an external lockfile for the actual storage. It only uses the version 1.85 features, so it should work almost everywhere. There will be one database and lockfile for each channel and all channel databases and locks will normally be collected in one directory.

video-entropyd is a program to add entropy data from video4linux devices to the kernel random driver.
For security reasons (when doing network traffic or generating secure keys for example) one wants as much entropy-data in the kernel random-driver as possible. The random-driver takes partially care for this. But in situations in where theres a lot of demand for entropy-data, it might not be able to gather enough entropy-data by itself.
Thats where this program is for: adding entropy-data to the kernel-driver. It does that by fetching 2 images from a video4linux-device (with a random delay in between), calculating the difference between those two and then calculating the number of information-bits in that data. After that, the data with the number-of-entropy-bits is submitted to the kernel-random-driver.
After that, the program exits (when run from crontab) or sleeps a random time before redoing the same process.
Enhancements:
- This version checks the quality of the data it feeds to the /dev/random-device to see if the data is really random.
- Extra logging has been added.

This application is particularly useful for owners of digital DV video cameras and other people who use the Sony DV video format for high quality video production.

DV Assembler allows you to append multiple Sony DV files with nice looking transition effects for both audio and video. Multiple transition effects are supported, like cross-fade, zoom, blur and a flash effect.

I created DV Assembler because there are no user friendly video editing applications for Linux. Yes, Kino is promising, but its user interface is still a mess and development is slow.

DV Assembler only touches the head and tail parts of the original video files that are needed to create the transition effects. The rest of the video is left untouched, which means zero quality loss.

DV Assembler can also be used to generate video editing scripts that can be run without KDE and Kommander.

mpeg2videotools is a C library and set of tools for encoding, decoding, verification and analysis of MPEG-2 video. It supports 422 Profile and High Profile bitstreams. A PSNR tool is included for comparing uncompressed video to encoded MPEG-2 video.
The library will provide a C API and be implemented in C. Platforms supported will be popular Unices and Linux, MS Windows and MacOSX. autoconf and automake will be used to achieve portability for most platforms. Decoded bitstreams will be displayed using X11 server for Unix and native Windows API for MS Windows.
Included is an encoder and decoder application which are useful for creating compliant bitstreams and decoding and verifying MPEG-ES, MPEG-PS, MPEG-PES and MPEG-TS bitstreams.
A number of important improvements over the original SSG code have already been made:
display on TrueColor visuals (16, 24, 32 bit displays)
decoding of MPEG-TS streams
decoding of broken streams which do not start with a required start code
autoconf build
MS Windows display
a library API to enable its use in other projects (ImageMagick and the AAF SDK come to mind)
MIAMI is an MPEG-2 video codec library which aims to be a complete implementation of the ISO/IEC 13812-2:2000 standard. The priority is completeness and correctness rather than speed. Included is an encoder and a decoder for MPEG-ES,PS,PES,TS bitstreams.
Enhancements:
- changed function decs to ANSI style
- added const qualifier to suitable function args

PSP Video Converter project is a simple graphical frontend to ffmpeg to allow you to easily convert your videos to PSP compatibile format. Works for me, thought I may share.

Note: Created with Kommander 1.3, not sure if it works with earlier Kommander.

Note: There is no error checking for now, so make sure you have a working ffmpeg with necessary codecs installed.

Note: Looks like some PSPs cant open h264 videos encoded with ffmpeg.

vdr_remote is a graphical remote control for the video disk recorder vdr. vdr_remote connects over a TCP/IP network and gives you a complete remote control.

iPod Video Encoder is a command line tool for convenient encoding of video files for use on iPod video. iPod Video Encoder project uses the ffmpeg tool for the actual encoding.
It features recursive encoding of all files in a directory, and generating a podcast.xml file for convenient use in iTunes.
It can be used in a cron job that periodically checks directories for new files and encodes them without user intervention.
Main features:
- Encoding of single files
- Optional specification of a/v bitrates
- Recursively encode all files in a directory
- Generating a podcast.xml for convenient use in iTunes
Options:
--version show programs version number and exit
-h, --help show this help message and exit
-R, --recursive Process directories recusively
-f, --force Force re-encode existing iPod videos
-t, --test Only encode first 10 seconds, to produce test videos
-e EXTENSIONS, --extensions=EXTENSIONS
Comma separated list of input extensions. Default: avi
-i IPODEXT, --ipodext=IPODEXT
iPod extension. Default: .ipod.mp4
-b VIDEO_RATE, --video-rate=VIDEO_RATE
Video bit rate, in kbps (default: 1024)
-a AUDIO_RATE, --audio-rate=AUDIO_RATE
Audio bit rate, in kbps (128)
-W WIDTH, --width=WIDTH
Video width, in pixels (default: 320)
-H HEIGHT, --height=HEIGHT
Video height, in pixels (default: 240)
-P, --pretend Do not really encode, just print out the ffmpeg
commands which would be executed
-v, --verbose Enable verbose output
Podcast options:
-p, --podcast Generate a podcast.xml file for each directory.
--podcast-documentroot=PODCAST_DOCUMENTROOT
Podcast document root; eg. /var/data/Movies/
--podcast-baseurl=PODCAST_BASEURL
Podcast base URL; eg. http://localhost/
Enhancements:
- Only uses the -e option for processing directories.
- The default ipod extension is now _ipod.mp4 for Windows compatibility.
- The README file has been extended with information on the .ipod-encoder settings file.
- The program no longer crashes when HOME is not set on Windows.
- --width and --height parameters have been added.

videocheck project is a simple program for checking and analyzing video AVI file structure.

The program is useful for recovering broken AVI files or finding bugs during development of software that produces AVI files.
