Original commit message from CVS:
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_buffer_alloc):
Even if we can't figure out the proper format to request downstream,
call buffer_alloc() downstream with the input parameters without setting
the caps on the srcpad. This will force negotiation in the chain
function.
Closes #350449
