我有一些小项目可以将视频流式传输到 android 设备。流媒体已完成，但我无法控制视频。当我按下暂停时，MediaController 不起作用，没有效果。VideoView.pause() 也不起作用。流服务器基于 GStreamer（服务器是我朋友写的），我使用的是 Android 2.2 CyanogenMod。
这是服务器代码：
#include <gst/gst.h>
#include <gst/rtsp-server/rtsp-server.h>
int
main (int argc, char *argv[])
{
GMainLoop *loop;
GstRTSPServer *server;
GstRTSPMediaMapping *mapping;
GstRTSPMediaFactory *factory;
gchar *str;
gst_init (&argc, &argv);
if (argc < 2) {
g_message ("usage: %s <filename>", argv[0]);
return -1;
}
loop = g_main_loop_new (NULL, FALSE);
/* create a server instance */
server = gst_rtsp_server_new ();
/* get the mapping for this server, every server has a default mapper object
* that be used to map uri mount points to media factories */
mapping = gst_rtsp_server_get_media_mapping (server);
str = g_strdup_printf ("( "
"filesrc location=\"%s\" ! decodebin2 name=d "
"d. ! queue ! videoscale ! video/x-raw-yuv, width=500, height=300 "
"! ffenc_mpeg4 ! rtpmp4vpay name=pay0 "
"d. ! queue ! audioconvert ! faac ! rtpmp4apay name=pay1"
" )", argv[1]);
/* make a media factory for a test stream. The default media factory can use
* gst-launch syntax to create pipelines.
* any launch line works as long as it contains elements named pay%d. Each
* element with pay%d names will be a stream */
factory = gst_rtsp_media_factory_new ();
gst_rtsp_media_factory_set_launch (factory, str);
g_free (str);
/* attach the test factory to the /test url */
gst_rtsp_media_mapping_add_factory (mapping, "/test", factory);
/* don't need the ref to the mapper anymore */
g_object_unref (mapping);
/* attach the server to the default maincontext */
gst_rtsp_server_attach (server, NULL);
/* start serving */
g_main_loop_run (loop);
return 0;
}
