Keep track if the buffer is configured and block activation when not configured
yet.
Keep track of outstanding buffers and disallow configuration when not all
buffers are returned to the pool. We need to do this or else we might end up
with wrong buffers in the pool.
Add return value to set_active.
Small cleanups. Fix finalize.
Use a GstStructure to provide the pool with the right configuration. Also
provide some helper methods to configure such a structure.
don't pass the config in alloc_buffer, pool implementation will already have
parsed it during set_config.
Update defs
It's often not obvious to people that elements like e.g. uridecodebin
(or demuxers) automatically support the standard signals of the
GstElement class, so let's print the useful pad-related ones for
elements with sometimes pads.
Make separate api for getting and adding metadata. This allows us to pass extra
parameters to the init functions when creating metadata, which is needed for
specific API implementations.
Add beginnings of memory metadata.
Add first implementation of arbitrary buffer metadata. We use a simple linked
linked of slice allocated metadata chunks. Future implementations could use
something more performant.
Add get, remove, iterate methods to handle the metadata.
Passing e.g. location=foo would lead to warnings because g_filename_to_uri()
wants an absolute file path and returns NULL otherwise. Use brand-new
gst_filename_to_uri() instead, which will try harder to create a proper
URI for us.
Also add unit test.
Add function that (unlike the GLib equivalent) also accepts paths that
aren't absolute and will clean up relative markers such as ./ and ../
before forming a URI.
Fixes warnings with e.g. filesrc location=foo ! typefind caused by the
recent switch to g_filename_to_uri(), but also actually creates valid
URIs for the first time.
Windows code paths could need some more work, e.g. we don't clean up
the relative markers there for now (because path could have \ and /
as separators).
API: gst_filename_to_uri()
When option "-i" is given, set an index object on the pipeline and compute
statistics for all index writers. Print a sumary when shutting down the
pipeline.
Add an owner private field where the owner of a buffer can store some extra
information. We can use this to implement most of the subclassing that happens
now. Later this will be removed and replaced by arbitrary buffer metadata.
