Postpone the #ifdef to a point after glib.h (via gstfdsink.h) is included
so that the needed defines and header includes can be done correctly,
especially on Visual C++ builds.

Save the value of the pad's got_eos in gst_funnel_release_pad,
before calling gst_element_remove_pad. This is because
gst_element_remove_pad may free the pad.

If multiple sources are plugged into the funnel and one of the
sources emits an EOS, that event is propogated through the funnel
even though other sources connected to the funnel may still be
pushing data. This patch waits to send an EOS event until the
funnel has received an EOS event on each sinkpad.
Ported from d397ea97 in 0.10 branch.
This adds properties to use the clock time for deciding when
to drop buffers for inactive pads and a property to buffer all
not rendered buffers for the active pad to allow pad switching
without losing any buffers at all.

In commit bf0964b6 a check for pad is activated was not carried.
This leads to attempt to pull while in push mode when force_caps
is set. In this case without the attached check even when activated
in pull mode we activate back to push mode.
This is from comment in previous code , case number eight:
8. if the sink pad is activated, we are in pull mode. succeed.
- otherwise activate both pads in push mode and succeed.
Putting it back fixes playback of webm in webkit+gstreamer 1.0 .

When we don't have the requested data in the ringbuffer and we move our read
pointer to the requested position, signal the delete cond to inform the writer
that we changed the current fill level. If we don't, the writer might stay
blocked and we might wait forever.
When we don't have enough bytes in the ringbuffer to satisfy the current
request, first update the current read position before waiting. If we don't do
that, the ringbuffer might appear full and the writer will never write more
bytes to wake us up.
Only add the range when we receive a segment event on the sinkpad. The add_range
method will modify the write position, which only makes sense to do on the
sinkpad.
Set the seeking flag right before we send a seek event upstream and discard all
data untill we see a flush-stop again. We need to do this because we activate
the range that we seek to immediately after sending the seek event and it is
possible that we receive data in our chain function from before the seek
which would then be added to the wrong range resulting in data corruption.
When using the ringbuffer, handle the newsegment event like we handle it when
using the temp-file mode: create a new range for the new byte segment. The new
segment should normally already be created when we do a seek.
Doesn't actually change the default value, just makes use of the
define there is. Superficial testing with fakesink and jpegdec did
not reveal improved performance for bigger block sizes, so leave
default as it is.
A flush from the upstream element should not make buffering go to 0, the next
pull request might be inside a range that we have and then we don't need to
buffer at all. If the next pull is outside anything we have, buffering will
happen as usual anyway.
We want to forward the flush events received on the sinkpad whenever the srcpad
is activated in pushmode, which can also happen when using the RINGBUFFER or
DOWNLOAD mode and downstream failed to activate us in pull mode.
When we have EOS, read the remaining bytes in the buffer and make sure we don't
wait for more data. Also clip the output buffer to the amount of remaining
bytes.
When using the ringbuffer mode, the buffer is filled when we reached the
max_level.bytes mark or the total size of the ringbuffer, whichever is smaller.
Use a threshold variable to hold the maximum distance from the current position
for with we will wait instead of doing a seek.
When using the ringbuffer and the requested offset is not available, avoid
waiting until the complete ringbuffer is filled but instead do a seek when the
requested data is further than the threshold.
Avoid doing the seek twice in the ringbuffer case.
Use the same threshold for ringbuffer and download buffering.
Remove GST_MAJORMINOR and replace it by GST_API_VERSION
Also set GST_VERSION_{MAJOR,MINOR,MICRO,NANO} explicitely
now.
All versions are at 1.0.0 now for the release soon but
API/ABI can still change until the 1.0.0 release.
Next release versions until 1.0.0 will be 0.10.9X and
these will be release candidates. GST_VERSION_* will
nonetheless stay at 1.0.0.0.
gst_buffer_take_memory -> gst_buffer_insert_memory because insert is what the
method does.
Make all methods deal with ranges so that we can replace, merge, remove and map
a certain subset of the memory in a buffer. With the new methods we can make
some code nicer and reuse more code. Being able to deal with a subset of the
buffer memory allows us to optimize more cases later (most notably RTP headers
and payload that could be in different memory objects).
Make some more convenient macros that call the more generic range methods.
We reset all the waiting streams, let them push another buffer to
see if they're now active again. This allows faster switching
between streams and prevents deadlocks if downstream does any
waiting too.
Also improve locking a bit, srcresult must be protected by the
multiqueue lock too because it's used/set from random threads.
Otherwise we might block forever because upstream (e.g. multiqueue) is waiting
for the previously active stream to return forever (which is waiting here
in inputselector) before pushing something on the newly selected stream.
Improve the docs of the get/pull_range functions, define the lifetime of the
buffer in case of errors and short reads.
Make sure the code does what the docs say.
Make it so that one can specify a buffer for get/pull_range where the downstream
element should write into. When passing NULL, upstream should allocate a buffer,
like in 0.10.
We also need to change the probes a little because before the pull probe, there
could already be a buffer passed. This then allows us to use the same PROBE
macro for before and after pulling.
While we're at the probes, make the query probe more powerful by handling the
GST_PAD_PROBE_DROP return value. Returning _DROP from a query probe will now
return TRUE upstream and will not forward the probe to the peer or handler.
Also handle _DROP for get/pull_range properly by not dispatching to the
peer/handler or by generating EOS when the probe returns DROP and no buffer.
Make filesrc handle the non-NULL buffer passed in the get_range function and
skip the allocation in that case, writing directly into the downstream provided
buffer.
Update tests because now we need to make sure to not pass a random value in the
buffer pointer to get/pull_range
Group the extra allocation parameters in a GstAllocationParams structure to make
it easier to deal with them and so that we can extend them later if needed.
Make gst_buffer_new_allocate() take the GstAllocationParams for added
functionality.
Add boxed type for GstAllocationParams.
Rename _do_simplify() to _simplify(). The name was introduced as a replacement
method for a deprecated method but we can now rename it again.
Fix some docs.
Make gst_caps_do_simplify() take ownership of the input caps and produce a
simplified output caps. This removes the requirement of having writable input
caps and the method can make the caps writable only when needed.
Rename gst_base_transform_suggest to gst_base_transform_reconfigure_sink because
that is what it does. Also remove the caps and size because that is not needed.
Rename gst_base_transform_reconfigure to gst_base_transform_reconfigure_src.
Remove some old unused code in capsfilter.
Make it possible to configure a GDestroyNotify and user_data for
gst_memory_new_wrapped() this allows for more flexible wrapping of foreign
memory blocks.
Remove the link functions and always start the pad task on the srcpad. If
applications need to autoplug they can put a blocking probe on the srcpad like
they would with any other element.
