tests/network-clock.scm: Commentary update. Original commit message from CVS: 2005-07-01 Andy Wingo <wingo@pobox.com> * tests/network-clock.scm: Commentary update. * gst/elements/gstidentity.c (PROP_DUPLICATE): Gone daddy gone. Didn't really make sense, not implementable with basetransform, etc. (gst_identity_transform): Unref inbuf via make_writable. Feeble attempt at implementing the sync property, needs an unlock method. * gst/base/gstbasetransform.c (gst_base_transform_transform_caps): New func, by default returns the same caps (the identity transformation). (gst_base_transform_getcaps): Uses transform_caps to return something sensible. (gst_base_transform_setcaps): Complicated logic to get caps on both pads, even if they are different, and to call set_caps once for every time both pads get their caps set. (gst_base_transform_handle_buffer): Give the ref to the transform function. Allows in-place modification of the buffer. * gst/base/gstbasetransform.h (transform_caps): New class method. Given caps on one side, what can I do on the other. (set_caps): Take two caps, one for each side of the element. * gst/gstpad.h: * gst/gstpad.c (gst_pad_fixate_caps): Change prototype to modify caps in place. This is safe because we can check the mutability of the caps, and a good idea because fixate functions are just called as a matter of last resort. (Not actually implemented.) (gst_pad_set_caps): If the caps we're setting is actually the same as the existing pad caps, just update the pointer without calling setcaps. Assert that caps is either NULL or fixed, as per the docs. * gst/gstghostpad.c: Update for fixate changes.

tests/network-clock.scm: Commentary update. Original commit message from CVS: 2005-07-01 Andy Wingo <wingo@pobox.com> * tests/network-clock.scm: Commentary update. * gst/elements/gstidentity.c (PROP_DUPLICATE): Gone daddy gone. Didn't really make sense, not implementable with basetransform, etc. (gst_identity_transform): Unref inbuf via make_writable. Feeble attempt at implementing the sync property, needs an unlock method. * gst/base/gstbasetransform.c (gst_base_transform_transform_caps): New func, by default returns the same caps (the identity transformation). (gst_base_transform_getcaps): Uses transform_caps to return something sensible. (gst_base_transform_setcaps): Complicated logic to get caps on both pads, even if they are different, and to call set_caps once for every time both pads get their caps set. (gst_base_transform_handle_buffer): Give the ref to the transform function. Allows in-place modification of the buffer. * gst/base/gstbasetransform.h (transform_caps): New class method. Given caps on one side, what can I do on the other. (set_caps): Take two caps, one for each side of the element. * gst/gstpad.h: * gst/gstpad.c (gst_pad_fixate_caps): Change prototype to modify caps in place. This is safe because we can check the mutability of the caps, and a good idea because fixate functions are just called as a matter of last resort. (Not actually implemented.) (gst_pad_set_caps): If the caps we're setting is actually the same as the existing pad caps, just update the pointer without calling setcaps. Assert that caps is either NULL or fixed, as per the docs. * gst/gstghostpad.c: Update for fixate changes.

Added function to check if pull_range can be performed. Error out when pulling inactive or flushing pads. Removed const from refcounted types as it does not make sense. Simplify pad templates in basesink Added base class for simple 1-to-1 transforms. Make identity subclass the base transform.
