You should not get rid of the entire assert no? Testing pointer nullity is still valid to me.

gst_pad_get_current_caps() can return NULL AFAIK. What should we do in that case instead of querying the caps to the pad?

Nothing, 0.10 GST_PAD_CAPS() macro you can also return NULL and this is handled gracefully by callers (by not painting).

Sorry I answered too fast. No the !ptr check is not valid, this is a OR. It is there only to prevent calling GST_OBJECT() with a NULL pointer. It's totally fine to store NULL in the GRefPtr.

Thank you Nicolas! Hopefully we'll turn gst-1.0 build support soon in the build-webkit.

Sorry again, selected the wrong option, hopefully setting it to ? now is enough.
