GStreamer - Perl interface to the GStreamer librarySYNOPSIS
use GStreamer -init; my $loop = Glib::MainLoop -> new(); # set up my $play = GStreamer::ElementFactory -> make("playbin", "play"); $play -> set(uri => Glib::filename_to_uri $file, "localhost"); $play -> get_bus() -> add_watch(\&my_bus_callback, $loop); $play -> set_state("playing"); # run $loop -> run(); # clean up $play -> set_state("null"); sub my_bus_callback { my ($bus, $message, $loop) = @_; if ($message -> type & "error") { warn $message -> error; $loop -> quit(); } elsif ($message -> type & "eos") { $loop -> quit(); } # remove message from the queue return TRUE; }
ABSTRACT
GStreamer makes everybody dance like crazy. It provides the means to play, stream, and convert nearly any type of media --- be it audio or video. GStreamer wraps the GStreamer library in a nice and Perlish way, freeing the programmer from any memory management and object casting hassles.INITIALIZATION
- GStreamer->init
- Initializes GStreamer. Automatically parses @ARGV, stripping any options known to GStreamer.
- boolean = GStreamer->init_check
- Checks if initialization is possible. Returns TRUE if so.
When importing GStreamer, you can pass the "-init" option to have GStreamer->init automatically called for you. If you need to know if initialization is possible without actually doing it, use GStreamer->init_check.
VERSION CHECKING
- boolean = GStreamer->CHECK_VERSION (major, minor, micro)
-
-
- *
- major (integer)
- *
- minor (integer)
- *
- micro (integer)
Returns TRUE if the GStreamer library version GStreamer was compiled against is newer than the one specified by the three arguments.
-
- (major, minor, micro) = GStreamer->GET_VERSION_INFO
- Returns the version information of the GStreamer library GStreamer was compiled against.
- (major, minor, micro) = GStreamer->version
- Returns the version information of the GStreamer library GStreamer is currently running against.
SEE ALSO
- GStreamer::index
- Lists the automatically generated API documentation pages.
- <http://gstreamer.freedesktop.org/>
- GStreamer's website has much useful information, including a good tutorial and of course the API reference, which is canonical for GStreamer as well.
- Gtk2::api
- Just like Gtk2, GStreamer tries to stick closely to the C API, deviating from it only when it makes things easier and/or more Perlish. Gtk2::api gives general rules for how to map from the C API to Perl, most of which also apply to GStreamer.
- Glib
- Glib is the foundation this binding is built upon. If you look for information on basic stuff like signals or object properties, this is what you should read.
