I am having some problems getting the dfbvideosink to play a video file. I
was able to use the example provided and play from the test video source.
After some searching I decided to try the playbin but I don't get any video
from that. How should I set up the pipeline? Here is what I have so far
#include <directfb.h>
#include <gst/gst.h>
static IDirectFB *dfb = NULL;
static IDirectFBSurface *primary = NULL;
static GMainLoop *loop;
#define DFBCHECK(x...) \
{ \
DFBResult err = x; \
\
if (err != DFB_OK) \
{ \
fprintf( stderr, "%s <%d>:\n\t", __FILE__, __LINE__ ); \
DirectFBErrorFatal( #x, err ); \
} \
}
static gboolean
get_me_out (gpointer data)
{
g_main_loop_quit (loop);
return FALSE;
}
int
main (int argc, char *argv[])
{
DFBSurfaceDescription dsc;
GstElement *pipeline, *sink;
/* Init both GStreamer and DirectFB */
DFBCHECK (DirectFBInit (&argc, &argv));
gst_init (&argc, &argv);
/* Creates DirectFB main context and set it to fullscreen layout */
DFBCHECK (DirectFBCreate (&dfb));
DFBCHECK (dfb->SetCooperativeLevel (dfb, DFSCL_FULLSCREEN));
/* We want a double buffered primary surface */
dsc.flags = DSDESC_CAPS;
dsc.caps = DSCAPS_PRIMARY | DSCAPS_FLIPPING;
DFBCHECK (dfb->CreateSurface (dfb, &dsc, &primary));
/* Creating our pipeline : videotestsrc ! dfbvideosink */
pipeline = gst_element_factory_make("playbin", NULL); //gst_pipeline_new
(NULL);
g_assert (pipeline);
sink = gst_element_factory_make ("dfbvideosink", NULL);
g_assert (sink);
/* That's the interesting part, giving the primary surface to dfbvideosink
*/
g_object_set (sink, "surface", primary, NULL);
g_object_set(pipeline, "uri", "file:///root/test.mp4", NULL);
g_object_set(pipeline, "video-sink", sink, NULL);
/* Let's play ! */
gst_element_set_state (pipeline, GST_STATE_PLAYING);
/* we need to run a GLib main loop to get out of here */
loop = g_main_loop_new (NULL, FALSE);
/* Get us out after 20 seconds */
g_timeout_add (20000, get_me_out, NULL);
g_main_loop_run (loop);
/* Release elements and stop playback */
gst_element_set_state (pipeline, GST_STATE_NULL);
/* Free the main loop */
g_main_loop_unref (loop);
/* Release DirectFB context and surface */
primary->Release (primary);
dfb->Release (dfb);
return 0;
}
The result is a brown screen (the default directfb color I think).
Thanks for your help
