[gst-devel] What's wrong with my getcaps() function?

[Corentin BARON]

Hello,

I'm building a video plugin and have problems with rgb output, it  
seems there's a problem with my getcaps() function but I can't figure  
it out. Here's my function:

> static GstCaps *
> gst_blinkysrc_getcaps(GstPad *pad)
> {
> 	GstCaps *capslist;
> 	GstBlinkySrc *filter = GST_BLINKYSRC(gst_pad_get_parent(pad));
> 	
> 	g_print("getcaps()\n");
> 	
> 	capslist = gst_caps_new_empty();
> 	
> 	// Are we connected to a device ?
> 	if (filter->handler != NULL && filter->buffer.image != NULL) {
> 		// In this case we know the width/height of our video
> 		gst_caps_append_structure(capslist,
> 			gst_structure_new("video/x-raw-rgb",
> 			"depth", G_TYPE_INT, 16,
> 			"bpp", G_TYPE_INT, 16,

I'm working on GStreamer 0.8.10 on Fedora Core 4 and Maemo (Nokia 770  
tablet).
Thx for yourt help,
