Free flv software for linux

QFlv2Avi project is a program to convert flv files (youtube for exemple) in avi files.

Hachoir metadata can extract metadata from archives (bzip2, gzip, zip, tar), audio (MPEG audio/MP3, WAV, Sun/NeXT audio, Ogg/Vorbis, MIDI, AIFF, AIFC, Real Audio), images (BMP, CUR, EMF, ICO, GIF, JPEG, PCX, PNG, TGA, TIFF, WMF, XCF), and video (ASF/WMV, AVI, Matroska, Quicktime, Ogg/Theora, Real Media).
It supports invalid or truncated files and Unicode text. It can remove duplicate values. Hachoir metadata project can also filter metadata according to priority.
Main features:
- Support invalid / truncated files
- Unicode compliant (charset ISO-8859-XX, UTF-8, UTF-16), convert string to your terminal charset
- Remove duplicate values (and if a string is a substring of another, just keep the longest one)
- Set priority to value, so its possible to filter metadata (option --level)
- Only depends on hachoir-parser (and not on libmatroska, libmpeg2, libvorbis, etc.)
Enhancements:
- This release reads the number of channels, bit rate, and sample rate, and computes the compression rate of Real Audio.
- It reads user comments of JPEG pictures.
- It computes the frame rate of Windows ANI.
- It normalizes language for ID3 and MKV.
- OLE2 and FLV extractors are now fault tolerant.

Yet Another MetaData Injector (yamdi) is a metadata injector for FLV files. It adds the onMetaData event to your FLV files. yamdi should run under *BSD and Linux (tested with FreeBSD, MacOSX and Ubuntu) and is published under the BSD license.
Why?
For a current project I have to add metadata to quite large FLV files (over 1GB). The other known free tools (flvmdi and flvtool2) are not suitable for that job because they read the whole file into memory. Because Im not very familiar with ruby (in order to modify flvtool2) and flvmdi is not open source I took the FLV specs and implemented a metadata injector in C. yamdi uses less memory and is faster.
Yet Another MetaData Injector for FLV injects the following metadata into your FLV files:
- creator
- metadatacreator
- hasKeyframes
- hasVideo
- hasAudio
- hasMetaData
- canSeekToEnd
- duration
- datasize
- videosize
- videocodecid
- audiosize
- audiocodecid
- audiosamplerate
- audiosamplesize
- stereo
- filesize
- lasttimestamp
- lastkeyframetimestamp
- lastkeyframelocation
- keyframes (filepositions, times)
- width
- height
- framerate
- videodatarate
- audiodatarate
Installation:
Download the source code and extract it with tar:
tar xzf yamdi-1.0.tar.gz
Change into the yamdi directory and compile the source code with:
cd yamdi-1.0
gcc yamdi.c -o yamdi -O2 -Wall
yamdi accepts four paramters:
-i The source FLV file.
-o The resulting FLV file with the metatags. If the output file is - the FLV file will be written to stdout.
-c A string that will be written into the creator tag. This parameter is optional
-h Displays a description of the available parameters
Examples:
yamdi -i sample.flv -o sample_with_metadata.flv
yamdi -i sample.flv -o - > sample_with_metadata.flv
yamdi -i sample.flv -o sample_with_metadata.flv -c "John Doe"
Enhancements:
- [Fix] Width and height calculation of ScreenVideo stream was wrong
- [Add] onLastSecond event with option -l

clive is a command line program that extracts videos from YouTube and Google Video websites. The project supports embedded video extraction, and can be used with ffmpeg to re-encode the extracted videos to different video formats (avi, mpeg, flv).

Want to watch Youtube video, but you dont have Flash plugin? (ex: gnu/linux ppc os), so try this great script to watch STREAMING VIDEOS from Youtube! You dont need to download video on your disk, you can stream directly the FLV videos from Youtube!

MPlayer Youtube Video Streamer lets you watch YouTube videos even if you dont have the flash plugin.

Usage: myvs [options] video_url

Options:

-h, --help print this help text and exit
-v, --version print program version and exit
-u USERNAME, --username=USERNAME account username
-p PASSWORD, --password=PASSWORD account password
-o FILE, --output=FILE output video file name
-q, --quiet activates quiet mode
-s, --stream do not download video, but stream directly by mplayer
-C, --cache set a cache of 300k, for slow connection
-c, --cycle cycle 20 times while youtube redirect to vo.llnwd.net (that streams .flv)
-t, --title use title in file name
-n, --netrc use .netrc authentication data
-O, --streamonly Force the script to stream only, if it doesnt find a valid stream server simply quit

Who to use it with Firefox:

Now I will explain you how to get it working with Firefox,

First we need a Firefox extension called: Lanchy,
this extension give us the ability to open directly from Firefox Youtube video on youtube webpage (not on all webpages that have a youtube video!

You ALWAYS need the youtube videos webpage! After you have installed Launchy (from firefoxs addon site), restart Firefox, now it will ask you to insert a Launchys button on your toolbar (DO IT! so open Youtube videos will be very simply), after that go on the preferences/option of this extension and uncheck the option: "search automatically programs".

Now copy the "launchy.xml" file that you found on the package and copy it on your directory:
".mozilla/firefox/YOUR_ID.default/chrome/" , after copied it, please dont forget to edit it with your myvs.py COMPLETE PATH, and add or delete oppurtune option to pass to the script.

Now restart again firefox an watch if it recognise the command (by pressing the G).

Go on youtube.com, open a video webpage, click on the G button-> Open in Mplayer Youtube Video Streamer.

PicoStreamer is a complete server for live audio/video streaming. It can stream MP3, AAC, and video live using Flash FLV. PicoStreamer does not require any Flash server. It only needs a Web server with Perl and PHP. It requires neither expensive dedicated servers nor compilation on the target machine.
A source client (for Win32) is included. A management/playing framework written in PHP makes PicoStreamer simple to use. The PicoIcy component acts as a local shoutcast server emulator, so you can use your preferred shoutcast source client to stream or stream Flash format directly from the Web.
Enhancements:
- Added live flash audio/video streaming support.
- Added Flash encoder.
- Added Flash player also for mp3.
- Added Brasilian (PT) language.
- Added dynamic playlist chooser.
- Added content-length managing.
- PicoIcy now in tray-bar.
- Fixed list blocking on weird chars.
- Removed php ctype_digits dependence.
- Removed perl html::entitites dependence.
- Fixed many minor bugs.

Palabre is an open source (and free as in free beer) XML Socket Python Server.
It is meant to be used in replacement (for example) of the Macromedia Flash Communication Server. (which is lets admit it really expensive)
Of course, its much more limited, but has all the basic functionnalities for connecting Flash based Clients through Xml Sockets (sending and receiving messages).
So you can use it to create, multiuser applications like a Chat, (almost) Real Time Flash Games, Online support, ...
It does not include Video streaming functions ( FLV via RTMP ) instead of Flash Communication Server.
Main features:
- Have multiple Rooms
- Each Room can have any parameter you want ( A title, a lock, operators, any flag, ...)
- The creator of the room can change this parameters
- The room can have Sub rooms (or child rooms)
- For Example, you can host 10 games and chats on a server, and each game has a lobby room for chatting, and as many subrooms as wanted. Players can chat, start a new game, wait for people to join, and then start the game. (Then the child room of the game can be "locked" so that no one else joins it.
- Have multiple clients
- They are identified by a nickname (like on IRC)
- One client can be in multiple rooms / subrooms
- Clients can send messages to a room
- Clients can send messages to other clients (private messages)
- Clients can send a broadcast message (or reserve this to root)
- Clients can ping the server
- Clients can ask for a "room message" to be sent back to them. (to test latency, ...)
Enhancements:
- Database identification support (< connect nickname="X" password="Y" / >)
- Clients params (< clientparam name="X" value="Y" / >)
- SubXML nodes : (< msg toroom="X" >< position >< x >12< /x >< /position >< /msg >)
- Customizable nodes (< mynode toroom="X" anyparam="Y" >< AnyContent >< /mynode >)
- Joined/Left information (< client name="Nickname" joined="Lobby" / >)
