I read that GST_DEBUG_CAPS is deprecated - and it does not work.
Is there any other way for debugging CAPS?
I wrote some function for this purpose but what if have caps with other
formats? It would be nice to have smth like GST_DEBUG_CAPS
.................................................................................................
void print_caps(Myfilter *filter)
{
int width=0,height=0;
guint32 fourcc;
if (GST_IS_CAPS(GST_PAD_CAPS(filter->sinkpad_video)))
{
GstStructure *sinkcaps = gst_caps_get_structure
(GST_PAD_CAPS(filter->sinkpad_video), 0);
gst_structure_get_int (sinkcaps, "width", &width);
gst_structure_get_int (sinkcaps, "height", &height);
gst_structure_get_fourcc (sinkcaps, "format", &fourcc);
switch (fourcc) {
case GST_MAKE_FOURCC ('I', '4', '2', '0'): GST_INFO("SINK CAPS:
width %d, height: %d format: I420\n",width,height);
break;
case GST_MAKE_FOURCC ('I', 'Y', 'U', '1'): GST_INFO("SINK
CAPS: width %d, height: %d format: IYU1\n",width,height);
break;
default:
GST_INFO("SINK CAPS: Incompatible format");
}
}
else
GST_WARNING("No caps on sink\n");
if (GST_IS_CAPS(GST_PAD_CAPS(filter->srcpad)))
{
GstStructure *srccaps = gst_caps_get_structure
(GST_PAD_CAPS(filter->srcpad), 0);
gst_structure_get_int (srccaps, "width", &width);
gst_structure_get_int (srccaps, "height", &height);
gst_structure_get_fourcc (srccaps, "format", &fourcc);
switch (fourcc) {
case GST_MAKE_FOURCC ('I', '4', '2', '0'): GST_INFO(" SRC CAPS:
width %d, height: %d format: I420\n",width,height);
break;
case GST_MAKE_FOURCC ('I', 'Y', 'U', '1'): GST_INFO("SRC
CAPS: width %d, height: %d format: IYU1\n",width,height);
break;
default:
GST_INFO("SRC CAPS: Not compatible format");
}
}
else
GST_WARNING("No caps on source\n");
}
