What is the LULOP2?

LULOP2 is a "Internet news gathering" platform, i.e. an integrated platform meant to perform -in an open publishing environment- the logistic and transaction stages of "news gathering" in the specific meaning that the broadcast news industry gives to the term (see ENG, SNG etc etc).

LULOP2 therefore is made bearing in mind the typical task of moving over the Internet large digital video files in compressed formats, handling server-side post-processing of such video files, allowing its web publishing with appropriate meta data and equally appropriate delivery methods, and finally enabling an Internet marketplace built around the concepts of automatic trading and dynamic pricing.

Currently we have developed the authentication and publishing core of the platform and we have been developing the FFmpeg module for Mpeg processing, the RSS module for real time notification, the Bittorrent module for effective distribution.

File packages

Version numbering goes as MAJOR.MINOR.PATCH. As now you are on the LULOP2 homepage, the MAJOR version is 2.
The basic intent is that MAJOR versions are incompatible, large-scale upgrades of the API and everything else add it. MINOR versions retain code compatibility with older minor versions, and changes in the PATCH level are perfectly compatible, forwards and backwards.
In any case, it is recommended that you upgrade always the PATCH level when new one is released.

CVS and test versions are released as YEAR-MONTH-DAY. Use these only for testing purposes.

  LULOP2 file releases are located at Sourceforge.net.

FAQ

Q: Who is the dog in the logo?
A: An Italian stallion, Lapo. It works in the Operational Headquarters of Synchronicity PBS, in Travaco, Pavia, Italy. It strays about 3 or 4 times a month. If you happen to been within 30 km radius from Pavia and see a dog looking like the logo, please call in Italy 0382 (Pavia) 492961 (office).

Q: How stable is the development code?
A: Near as possible the stable one, but might sometimes result "notice" level errors and sometimes unmatched SQL queries.

Q: How is this project related to Tsuka?
A: Althought both projects involve the same person, Jukka Paasonen, they are based on their own code base, thus developed separately.

Q: Is there a way to add things on my own to the platform?
A: Yes, look at the developer documentation, specially the section called "modules".

Q: How do I use the BitTorrent integration?
A: Setup an Torrent tracker, the one you most prefer. Then enable the use of torrents in the configuration and set the correct announce url.

Q: Which image formats are supported for the thumbnail still image of the video?
A: Same as in PHP: jpeg, gif, png and some others. It is also possible make the still straight from the video itself, thought FFmpeg.

Q: I noticed the similarity of the upload progress bar with Megaupload from raditha.com. How come?
A: Well noticed. Indeed it was the source where our upload progress was originated, but there is many changes and improvements for our system, so therefore it is now quote different from Megaupload.

Q: I tried to use different session.save_handler than "files" but my upload is not working anymore. Why?
A: The clue between sessions in PHP -> Perl, is to use file based session handling. Therefore you cannot currently use any other than "files". Although using "mm" would be the fastest way. If the Perl module PHP::Session will be someday updated, then we will see.

Q: I have installed XXX FTP daemon on my server. Does LULOP2 work with it?
A: If it has support for authentication via MySQL and virtual users. We use PureFTPd for that.

Q: I would like to use GetID3 version 2 while now this project uses GetID3 v1.7.3, can I?
A: Of course. Just make sure that you change the settings in l2_config.php and you have PHP version 5.

Q: Why LULOP2?
A: After 4 years of trading video over the old lulop, we had an idea of what could be an effective hub for video trading in terms of users authentication, video uploads, content access, effective notification and push.

Q: Does it have RSS?
A: Sure, just needs to be enabled from the configuration. It also has "The Market Maker" extension with all info for real-time licensing of your videos.

Q: I hate downloading a 750 megs .avi file only to know if its "The Matrix Reloaded" rip or 3 minutes of useless DV footage, does LULOP2 help?
A: Yes LULOP2 is able to read tags attached to video and audio files so you know screen size, data rate, audio sample rate without having to take the file onto your desktop

Q: But I prefer FTP so I don't need LULOP2
A: Wrong, LULOP2 is also an FTP site which lets you upload to folders which you can then manage via browser

Q: I manage multiple FTP accounts for my contributors and it drives me crazy
A: LULOP2 lets you manage all accounts via browser, no need to remind all passwords or check all folders for updates

Q: I want to select who has access to my videos
A: LULOP2 lets you specify different degree of publication and also discriminate between different users through channels

Q: I am afraid of wasting bandwidth when I publish broadcast videos, does LULOP2 help
A: Yes, it has a BitTorrent integration and RSS of BitTorrent for effective content push and bandwidth savings
