Use the gstreamer plug-in playbin to develop a simple Media Player for video and music.

Source: http://blog.163.com/lixiangqiu_9202/blog/static/535750372012111911544314/

First, install the gstreamer development environment.

Search for installation instructions

The following is a simple example, with some Codes commented out by me.

Some part of the commented-out code is used during my practice, and some parts are set to set the URI path for opening the file.

However, after this setting, you will not be able to play the media from the network, so comment it out.

The code below

# Include <GST/GST. h>
# Include <string. h>
Void error_quit (ststbus * bus, ststmessage * message, gmainloop * loop)
{
Gerror * error;
Ststst_message_parse_error (message, & error, null );
Printf ("error: % s \ n", error-> message );
G_main_loop_quit (loop );
}
Void end_of_streamer (ststbus * bus, ststmessage * message, gmainloop * loop)
{
Printf ("End of streamer... \ n ");
G_main_loop_quit (loop );
}
Void print_pos (maid * pipe)
{
Ststformat fm = maid;
Gint64 POs, Len;
Ststst_element_query_position (pipe, & FM, & Pos );
Ststst_element_query_duration (pipe, & FM, & Len );
Printf ("Time: % u: % 02u: % 02u/% u: % 02u: % 02u: % 02u \ n", maid (POS), maid (LEN ));
}
Int main (INT argc, char ** argv)
{
Gmainloop * loop;
Gstelement * playpipe;
// Stststelement * source;
Gstbus * bus;
// Gchar * file_name;
Gst_init (& argc, & argv );
Loop = g_main_loop_new (null, false );
Playpipe = maid ("playbin", "Play-source ");
// Playpipe = maid ("Play-pipe ");
// Maid (playpipe), source );
// Maid (playpipe, source );
// G_object_set (g_object (playpipe), "location", argv [1], null );
// File_name = malloc (sizeof (gchar) * 7 + strlen (argv [1]) + 1 );
// Strcpy (file_name, "file ://");
// Strcat (file_name, argv [1]);
G_object_set (g_object (playpipe), "Uri", argv [1], null );
Bus = maid (maid ));
Ststst_bus_add_signal_watch (bus );
G_signal_connect (g_object (bus), "message: error", g_callback (error_quit), loop );
G_signal_connect (g_object (bus), "message: EOS", g_callback (end_of_streamer), loop );
Printf ("start... \ n ");
Ststst_element_set_state (playpipe, ststst_state_playing );
G_timeout_add (1000, (void *) print_pos, playpipe );
G_main_loop_run (loop );
Ststst_element_set_state (playpipe, ststst_state_null );
Return 0;
}

Compile

Gcc-O playbin. c 'pkg-config -- cflags -- libs gstreamer-0.10'

Note: The media path is set as follows:

#./Playbin file: // root/Media/Jiangnan. Avi

Gstreamer supports "file: // <path>/<File>", "http: // To enable the source component or the receiving component to support a specific URI, use the stst_element_make_from_uri () function.
The source component uses the stst_uri_src type, and the receiving component uses the stst_uri_sink type.
