====== Streaming ogg Audio/Video opensource ======
Autore: **//Fabio Di Matteo//** \\ Ultima revisione: **//08/08/2009//** \\ \\
===== Quello che serve =====
- Applet java per lo streaming --> [[http://theora.org/cortado.jar|Cortado]]
- ffmpeg2theora per convertire i video e audio nel formato ogg (per unix liberi)
===== Prepariamo un file video di prova =====
ffmpeg2theora filevideoqualsiasi.avi
verrà generato un file video .ogg , rinominiamolo video.ogg .
===== Preparazione html e javascript =====
Scarichiamo l'applet e rinominiamola in ''cortado.jar'' , e mettiamola nella stessa directory del video.
prepariamo la pagina (anche essa da mettere nella stessa directory del video):
===== Altri parametri da passare all'applets =====
I parametri all'applets si passano in questa maniera:
Gli altri possibili valori possono essere i seguenti presi dal [https://code.fluendo.com/flumotion/trac/browser/cortado/trunk/README|README originale]]
url: string
the URL to load, must be a fully qualified URL.
IMPORTANT: if the applet is not signed, the hostname of the
url *is required* to be the same as the hostname of the link
to the page with the applet tag. This is a Java security limitation.
seekable: enum (auto|true|false)
Whether or not you can seek in the file. For live streams,
this should be false; for on-demand files, this can be true.
In automatic mode, the stream becomes seekable when the content
length is discovered.
Defaults to auto
live enum (auto|true|false)
Whether or not this file is a live stream. For live streams,
this should be true, which will disable the PAUSE button.
For on-demand files, this can be false.
In automatic mode, the stream becomes non-live when the content
length is discovered.
Defaults to auto
duration: int
Length of clip in seconds. Needed when seekable is true,
to allow the seek bar to work.
keepAspect: boolean
Try to keep the natural aspect of the video when resizing the
applet window. true or false.
Defaults to true
video: boolean
Use video. When not using video, this property will not create
resources to play a video stream. true or false.
Defaults to true
audio: boolean
Use audio. When not using audio, this property will not create
resources to play an audio stream. true or false.
Defaults to true
statusHeight: int
The height of the status area (default 12)
autoPlay: boolean
Automatically start playback (default true)
showStatus: enum (auto|show|hide)
Controls how to make the status area visible.
auto will show the status area when hovered over with the mouse.
hide will only show the status area on error.
show will always show the status area.
(default auto)
hideTimeout: int
Timeout in seconds to hide the status area when showStatus is
auto. This timeout is to make sure that the status area is visible
for the first timeout seconds of playback so that the user can see
that there is a clickable status area too.
(default 0)
bufferSize: int
The size of the network buffer, in KB.
A good value is max Kbps of the stream * 33
Defaults to 200
bufferLow: int
Percentage of low watermark for buffer. Below this, the applet
will stop playing and rebuffer until the high watermark is
reached.
Defaults to 10
bufferHigh: int
Percentage of high watermark for buffer. At startup or when
rebuffering, the applet will not play until this percentage of
buffer fill status is reached.
Defaults to 70
userId: string
user id for basic authentication.
password: string
password for basic authentication.
debug: int
debug level, 0 - 4. Defaults to 3. Output goes to the Java
console.
