| caps issues: | |
| - We can't really tell until PAUSED that 'sinesrc ! identity ! ximagesink' | |
| will fail (since identity has ANY as the pad template caps). | |
| Because of this, it's nearly useless to perform the pad | |
| template check. | |
| Alternatives: | |
| proxy pad template caps, but that reinstates the O(N^2) issue | |
| in 0.8 during linking lots of elements. | |
| remove checking of pad template caps compatibility | |
| add a means of checking a pipeline for caps compatibility before | |
| setting to PAUSED (ugly, requires special processing in each | |
| element) | |
