FLV::Header is a flash video file data structure.

METHODS

This is a subclass of FLV::Base.

$self->parse($fileinst)

Takes a FLV::File instance and extracts the FLV header from the file stream. This method throws exceptions if the stream is not a valid FLV v1.0 or v1.1 file. The interpretation is a bit stricter than other FLV parsers (for example FLVTool2).

There is no return value.

$self->serialize($filehandle)

Serializes the in-memory FLV header. If that representation is not complete, this throws an exception via croak(). Returns a boolean indicating whether writing to the file handle was successful.

$self->has_video()

Returns a boolean indicating if the FLV header predicts that video data is enclosed in the stream.

This value is not consulted internally.

$self->has_audio()

Returns a boolean indicating if the FLV header predicts that audio data is enclosed in the stream.

This value is not consulted internally.

FLV::Tag is a flash video file data structure.

This is a subclass of FLV::Base.

$self->parse($fileinst)

Takes a FLV::File instance and extracts an FLV tag from the file stream. This method then multiplexes that tag into one of the subtypes: video, audio or meta. This method throws exceptions if the stream is not a valid FLV v1.0 or v1.1 file.

At the end, this method stores the subtag instance, which can be retrieved with get_payload().

There is no return value.

$self->get_payload()

Returns the subtag instance found by parse(). This will be instance of FLV::VideoTag, FLV::AudioTag or FLV::MetaTag.

$pkg->serialize($tag, $filehandle)
$self->serialize($tag, $filehandle)

Serializes the specified video, audio or meta tag. If that representation is not complete, this throws an exception via croak(). Returns a boolean indicating whether writing to the file handle was successful.

WWW::Google::Video is a fetch the Google Video Information.

SYNOPSIS

use WWW::Google::Video;

$foo=new WWW::Google::Video;

$foo->fetch(http://video.google.com/videoplay?docid=1808273720725631796);
# The Google Video Page URL, such as http://video.google.com/videoplay?docid=blahblahblah

print $foo->{url},"n"; # Google Video FLV Original File URL !!
print $foo->{length},"n"; # Video Length Information
print $foo->{name},"n"; # Video Name Information

foreach(@{ $foo->{pic} }){ # By using Reference to an Array
print $_,"n"; # To show the preview pictures.
}

The WWW::Google::Video is a class implementing a interface for fetch the Google Video Information.

To use it, you should create WWW::Google::Video object and use its method fetch(), to fetch the information of Video.

It uses LWP::Simple for making request to Google.

FLV::ToMP3 can convert audio from a FLV file into an MP3 file.

SYNOPSIS

use FLV::ToMP3;
my $converter = FLV::ToMP3->new();
$converter->parse_flv($flv_filename);
$converter->save($mp3_filename);

See also flv2mp3.

Extracts audio data from an FLV file and constructs an MP3 file. See the flv2mp3 command-line program for a nice interface and a detailed list of caveats and limitations.

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" / >)

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

Mod-Cache is a cache(reverse-proxy) accelerator plugin for lighttpd, which works like Squid with similar configuration. However mod_cache is faster and more effective than Squid because of powerful Lighttpd.
Mod-Cache has following advantages over Squid:
- Simpler. Mod-Cache just sets proper flags between lighttpd request handling stages. Request is handled by mod_staticfile or mod_compress or other modules.
- More Robust. Mod-Cache uses disk file instead of memory as cache. Without use of memory, mod_cache is far away from memory leaks and memory exhaustion.
- Faster. Lighttpd uses Sendfile syscall to service disk file. Sendfile syscall, which writes file to network interface directly, has the same effecience as Writev syscall which writes memory buffers to network interface.
- More Powerful. Mod-Cache can works with other lighttpd plugins(except mod_deflate). For examples, you can use mod_compress to compress cached files on-fly; or you can use mod_access/mod_trigger_b4_dl to do anti-hot-link; or you can use mod_flv_streaming to do native flv file streaming.
Enhancements:
- lighttpd 1.5 was upgraded to r1811.
- The status page for mod_status was added.
- cache.ignore-hostname was added.
- A bug for checking the cachehd file was fixed.

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