Hi experts:
OS: Ubuntu 16.04.6 LTS
Gstreamer Version: GStreamer 1.8.3
I want to write an application to play mp4 file base on gstreamer, my code:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
......
pipeline = gst_pipeline_new("my-pipeline");
filesrc = gst_element_factory_make ("filesrc",NULL);
demux = gst_element_factory_make("qtdemux",NULL);
decoder = gst_element_factory_make("avdec_h264",NULL);
sink = gst_element_factory_make("xvimagesink",NULL);
g_object_set(G_OBJECT(filesrc),"location",argv[1],NULL);
gst_bin_add_many(GST_BIN (pipeline),filesrc,demux,decoder,sink,NULL);
if(gst_element_link_many(filesrc,demux,decoder,sink,NULL)!=TRUE)
{
g_error ("Failed to link");
}
......
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I add GST_DEBUG=4 before executing, error show:
````````````````````````````````````````````````````````````````````````````````````````````````
GST_ELEMENT_PADS gstelement.c:904:gst_element_get_static_pad: no such pad 'video_%u' in element "qtdemux0"
GST_ELEMENT_PADS gstutils.c:1124:gst_element_get_compatible_pad:<qtdemux0> Could not find a compatible pad to link to filter:sink
````````````````````````````````````````````````````````````````````````````````````````````````
My question:
how to manually add pad "video_%u" to qtdemux?
