Free flv toswf software for linux

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.

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.

FLV::Body 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 body from the file stream. This method throws exceptions if the stream is not a valid FLV v1.0 or v1.1 file.

There is no return value.

$self->serialize($filehandle)

Serializes the in-memory FLV body. 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->get_info()

Returns a hash of FLV metadata. See File::Info for more details.

$self->get_tags()

Returns an array of tag instances.

$self->count_video_frames()

Returns the number of video tags in the FLV stream.

$self->count_audio_packets()

Returns the number of audio tags in the FLV stream.

$self->count_meta_tags()

Returns the number of meta tags in the FLV stream.

$self->last_start_time()

Returns the start timestamp of the last tag, in milliseconds.

$self->get_meta($key);
$self->set_meta($key, $value);

These are convenience functions for interacting with an onMetadata tag at time 0, which is a common convention in FLV files. If the 0th tag is not an FLV::MetaTag instance, one is created and prepended to the tag list.

See also get_value and set_value in FLV::MetaTag.

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::VideoTag is a flash video file data structure Perl module.

METHODS

This is a subclass of FLV::Base.

$self->parse($fileinst)

Takes a FLV::File instance and extracts an FLV video tag from the file stream. This method throws exceptions if the stream is not a valid FLV v1.0 or v1.1 file.

There is no return value.

Note: this method needs more work to extract the codec specific data.

$self->serialize()

Returns a byte string representation of the tag data. Throws an exception via croak() on error.

$self->get_info()

Returns a hash of FLV metadata. See File::Info for more details.

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.

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
