2666450864 Suppress deprecation warnings in selected files, for g_static_rec_mutex_* mostly
GStaticRecMutex is part of our API/ABI, not much we can do here in 0.10.

5889260d5a Work around deprecated thread API in glib master
Add private replacements for deprecated functions such as
g_mutex_new(), g_mutex_free(), g_cond_new() etc., mostly
to avoid the deprecation warnings. We can't change most of
these in 0.10 because they're part of our API and ABI.

e6d2da7cf8 basetransform: Always intersect the suggested sink caps with the peer caps
This makes sure that we get correct and complete caps. The suggested caps
could be incomplete, e.g. video/x-raw-rgb without any fields, and by
intersecting with the peer caps we get something usable.

Fixes bug #662199.

2f1ed65339 pad: Merge pad mode activation functions
Add the pad mode to the activate function so that we can reuse the same function
for all activation modes. This makes the core logic smaller and allows for some
elements to make their activation code easier. It would allow us to add more
scheduling modes later without having to add more activate functions.

b5c3e254b1 pad: remove getcaps and use caps query
Remove the getcaps function on the pad and use the CAPS query for
the same effect.
Add PROXY_CAPS to the pad flags. This instructs the default caps event and query
handlers to pass on the CAPS related queries and events. This simplifies a lot
of elements that passtrough caps negotiation.
Make two utility functions to proxy caps queries and aggregate the result. Needs
to use the pad forward function instead later.
Make the _query_peer_ utility functions use the gst_pad_peer_query() function to
make sure the probes are emited properly.

01172b8126 basetransform: send delayed events earlier
Some elements (such as videorate) might push buffers early,
for instance in in transform_ip. We want events (and in particular
any NEWSEGMENT event) to be pushed before that.

This fixes transmageddon wedging on converting a file starting
with a non zero offset to Ogg.

bdbc069348 Rework GstSegment handling
Improve GstSegment, rename some fields. The idea is to have the GstSegment
structure represent the timing structure of the buffers as they are generated by
the source or demuxer element.
gst_segment_set_seek() -> gst_segment_do_seek()
Rename the NEWSEGMENT event to SEGMENT.
Make parsing of the SEGMENT event into a GstSegment structure.
Pass a GstSegment structure when making a new SEGMENT event. This allows us to
pass the timing info directly to the next element. No accumulation is needed in
the receiving element, all the info is inside the element.
Remove gst_segment_set_newsegment(): This function as used to accumulate
segments received from upstream, which is now not needed anymore because the
segment event contains the complete timing information.

Don't use GST_PAD_CAPS but instead use the new gst_pad_get_current_caps()
method.

c4751ec8c1 Revert "context: use context on buffers instead of caps"
This reverts commit 9ef1346b1f.

Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.

e7bf5484c7 base: Fix pad callbacks so they handle when parent goes away
1) We need to lock and get a strong ref to the parent, if still there.
2) If it has gone away, we need to handle that gracefully.

This is necessary in order to safely modify a running pipeline. Has been
observed when a streaming thread is doing a buffer_alloc() while an
application thread sends an event on a pad further downstream, and from
within a pad probe (holding STREAM_LOCK) carries out the pipeline plumbing
while the streaming thread has its buffer_alloc() in progress.

83597767b1 basetransform: Be smarter with pad allocs
Avoid doing unnecessary pad-allocs when on passthrough mode.
If multiple basetransform elements are on a pipeline, they
would do a pad-alloc for each received buffer, each element
would do this, so we would have lots of pad allocs on the
pipeline for a single buffer being pushed through it.

This patch attempts to reduce this amount by avoiding
doing pad-allocs if the element has already done it
after the last pushed buffer. So it will only be allowed
to do a new pad-alloc after it has pushed a buffer, so we get
1x1 pad-alloc and buffer ratio

0a74684b41 basetransform: Handle downstream giving a buffer with new caps but invalid size
This can happen for example when downstream proposed new caps, later proposed
the previous caps again which in turn enables passthrough mode in upstream
elements and the wrong-sized buffer appears in an element where the caps
change never happened. Simply allocate a new buffer in this case.

29289ee79e basetransform fix for upstream caps-renegotiation
If initially pass-through caps are negotiated between a transform element's
sink and src pads, but then the downstream element returns different caps
on a buffer from pad_alloc(), basetransform gets stuck with proxy_alloc=TRUE
even though the upstream peer doesn't accept the caps, causing
gst_pad_peer_accept_caps() to be called on each buffer in _buffer_alloc():

    if (!gst_caps_is_equal (newcaps, caps)) {
      GST_DEBUG_OBJECT (trans, "caps are new");
      /* we have new caps, see if we can proxy downstream */
>>    if (gst_pad_peer_accept_caps (pad, newcaps)) {
        /* peer accepts the caps, return a buffer in this format */
        GST_DEBUG_OBJECT (trans, "peer accepted new caps");

which is taking ~40ms/frame.

This patch does two things.  (1) if the buffer returned from pad_alloc() has
new caps, trigger the decision whether to proxy the buffer-alloc to be
revisited, and (2) disable proxy if peer does not accept new caps.  (The first
part may not be strictly needed, but seemed like a good idea.)

Note that this issue would not arise except in case of downstream elements
who have on their template-caps, some that would be suitable for pass-through,
but at runtime pick more restrictive caps (for ex, after querying a driver for
what formats it actually supports).

574e6ab423 basetransform: Try suggesting caps on bad caps pad_alloc
When basetransform received an unsupported caps on pad_alloc
it just returned not-negotiated. This patch makes it query
the allowed caps between his sinkpad and upstream's srcpad
to find a caps to suggest.

This happens when dinamically switching pipeline elements
and upstream pad_allocs with the previous caps that was
being used.
