Hi All,
I am trying to play a mp4 file. When I play from command line using the
pipe:
"gst-launch filesrc location=/home/ashwini/streams/output.ts ! mpegtsparse !
mpegtsdemux ! decodebin ! ffmpegcolorspace ! ximagesink"
The video is displayed well.
But when i try to achieve the same pipe thru the application, It fails.
The code snippet of pipelie creation is as follows:
pipeline = gst_pipeline_new ("gst-player");
//gst_debug_set_default_threshold(GST_LEVEL_DEBUG);
gst_debug_set_threshold_for_name("mpegtsparse",GST_LEVEL_DEBUG);
src = gst_element_factory_make ("filesrc", NULL);
g_assert (src);
g_print("URI = %s\n",uri);
g_object_set (G_OBJECT (src), "location", uri, NULL);
parse = gst_element_factory_make ("mpegtsparse", NULL);
g_assert (parse);
demux = gst_element_factory_make ("mpegtsdemux", NULL);
g_assert (demux);
dec = gst_element_factory_make ("decodebin", NULL);
g_assert (dec);
csp = gst_element_factory_make ("ffmpegcolorspace", NULL);
g_assert (csp);
videosink = gst_element_factory_make ("ximagesink", NULL);
g_assert (videosink);
/* Adding elements to the pipeline */
gst_bin_add_many (GST_BIN (pipeline), src, parse, demux, dec, csp,
videosink, NULL);
// gst_bin_add_many (GST_BIN (pipeline), src, videosink, NULL);
// g_assert (gst_element_link_many (src, parse, demux, dec, csp,
videosink, NULL));
g_assert (gst_element_link (src, parse));
g_assert (gst_element_link (parse, demux));
gst_element_link (demux, dec);
(gst_element_link (dec, csp));
(gst_element_link (csp, videosink));
if (GST_IS_X_OVERLAY (videosink))
{
gst_x_overlay_set_xwindow_id (GST_X_OVERLAY (videosink),
GPOINTER_TO_INT (window));
}
gst_element_set_state (pipeline, GST_STATE_PLAYING);
What could be causing it to fail. (In the above snippet described, I have
used the gst-player code and modified the pipe to current state)
Any help is appreciated.
