Fixed gst_caps_is_strictly_equal() to take into account whether either of the caps are ANY caps. Previously, two ANY caps could be considered not strictly equal if one of them still contained some remnant *internal* structure (this can happen if an ANY caps has emerged from an append or merge operation). Also, an ANY caps with no remnant internal structures was considered strictly equal to an EMPTY caps. Similarly, a non-ANY caps was considered strictly equal to an ANY caps if its remnant internal structures happened to match. Also changed gst_caps_is_fixed to take into account that an ANY caps should not be considered fixed even if it contains a single remnant internal fixed structure. This affects gst_caps_is_equal(), which uses a separate method if both caps are fixed. Previously, this meant that a non-ANY fixed caps was considered equal to an ANY caps if it contained a single matching remnant internal structure. Added some tests for these two equality methods, which covers the above examples, as well as asserts existing behaviour. Fixes #496 |
