HI,
I am wondering if any of u could help in any way.. :)
I am currently working on a Intelce4100 based settop box and happen to use
ismd_vidrend_sink. My application is such that video should be played in a
particular Directfb rectangle. I am using ismd_vidrend_sink and with the
property "rectangle". I could get the video playing in the gdl-plane but
not in the desired directfb rectangle. I am a newbie to ismd and wonder if
i am doing things right here...
Below is a overview of my code:
static void
dfb_update(player_stream_t *player_stream)
{
if (! player_stream)
{
return;
}
if (player_stream->fVideoSink && player_stream->fIsPlaying)
{
/* That's the interesting part, giving the dfb video
surface to dfbvideosink */
printf("dfb Update ###########Co ordinates for Rectangle :
%s\n",rectangle_desc);
g_object_set(peer_player_stream->fVideoSink,"rectangle",rectangle_desc,
NULL);
}
}
static slim_int
dfb_initialize (player_stream_t *player_stream)
{
slim_int iResult = SLIM_E_OK;
/* ------------------------------------------------
* DirectFB Surface Initialization for media player
* ------------------------------------------------
*/
if (! player_stream || ! player_stream->fPeerPlayer)
{
return SLIM_E_GENERIC;
}
/* Restrict video area to rectangle*/
rect.x = player_stream->fPeerPlayer->fDisplayParam.xpos;
rect.y = player_stream->fPeerPlayer->fDisplayParam.ypos;
rect.w = player_stream->fPeerPlayer->fDisplayParam.width;
rect.h = player_stream->fPeerPlayer->fDisplayParam.height;
rectangle_desc=g_strdup_printf("%d,%d,%d,%d",rect.x,rect.y,rect.w,rect.h);
printf("dfb Initialize ###########Co ordinates for Rectangle :
%s\n",rectangle_desc);
/*
* GetSubsurface from primary surface and restrict it to the
rectangle. Instead of using
* the surface created for the gst-player we directly get the
subsurface of the primary
* surface created by dfb by which we can avoid extra operations
* */
g_object_set(peer_player_stream->fVideoSink,
"rectangle",rectangle_desc, NULL); // This seems to me the problem as it
always gives GLib-GObject-CRITICAL **: g_object_set: assertion `G_IS_OBJECT
(object)' failed.
gWavePeerPrimary->GetSubSurface( gWavePeerPrimary, &rect,
&peer_player_stream->fVideoSink);
peer_player_dfb_update(peer_player_stream);
/* Cleanup underlying Surface */
DFBCHECK(gWavePeerPrimary->Clear(gWavePeerPrimary, 0, 0, 0, 0x80));
return iResult;
}
static void
peer_player_gst_init(peer_player_stream_t *peer_player_stream)
{
GstBus *bus = NULL;
GstPad* pad;
DFBCHECK (DirectFBInit (NULL, NULL));
gst_init (NULL, NULL);
/* Create the bin and its elements */
peer_player_stream->fVideoSink = gst_element_factory_make
("ismd_vidrend_bin", "ismd_videosink");
bus = gst_pipeline_get_bus (GST_PIPELINE
(peer_player_stream->fPlay));
gst_bus_add_watch (bus, peer_player_gst_bus_callback,
peer_player_stream);
gst_object_unref (bus);
gst_bin_add(GST_BIN(peer_player_stream->fBin),
peer_player_stream->fVideoSink);
/* Create the ghost pad and let the it point to bin's first
element's sink */
pad = gst_element_get_static_pad(peer_player_stream->fVideoSink,
"sink");
gst_element_add_pad(peer_player_stream->fBin,
gst_ghost_pad_new("sink", pad));
gst_object_unref(GST_OBJECT (pad));
}
static void
peer_player_gst_prepare_to_play(peer_player_stream_t *peer_player_stream)
{
slim_int gst_flags;
g_object_get (G_OBJECT (peer_player_stream->fPlay), "flags",
&gst_flags, NULL);
g_object_set (G_OBJECT (peer_player_stream->fPlay), "flags",
gst_flags, NULL);
g_object_set (G_OBJECT (peer_player_stream->fPlay), "buffer-size",
1024*1024, NULL);
g_object_set (G_OBJECT (peer_player_stream->fPlay), "uri",
peer_player_stream->fUri, NULL);
g_object_set(peer_player_stream->fVideoSink,"rectangle",rectangle_desc,NULL);
g_object_set(peer_player_stream->fVideoSink,"gdl-plane","UPPC",NULL);
/* Set the video surface to dfbvideosink property "surface" */
peer_player_dfb_update(peer_player_stream);
peer_player_set_event(peer_player_stream);
g_play = peer_player_stream->fPlay;
if(g_play) {
if(g_mute) {
g_object_set(G_OBJECT(g_play), "volume", 0.0, NULL);
}
else {
g_object_set(G_OBJECT(g_play), "volume", g_vol,
NULL);
}
}
peer_player_stream->fSpeed = NORMAL_SPEED;
if (gst_element_set_state(peer_player_stream->fPlay,
GST_STATE_READY) == GST_STATE_CHANGE_FAILURE) {
printf("peer_player_gst_prepare_to_play() - Error: Pipeline
Is Not Ready\n");
else
{
/* TODO Normally the autovideo sink would create an own
output window, so we set GstXOverlay for outputting video to browser
window. */
g_object_set (G_OBJECT (peer_player_stream->fPlay),
"video-sink", peer_player_stream->fBin , NULL);
}
}
I am just stuck here and going no where....
thanks in advance

Sudhir .
