bf88547489 v4l2xoverlay: add support to create window
If xoverlay is available, v4l2sink should create a window for the overlay to
display in.

The window automatically tries to make itself as large as possible.
This works well on a small screen, but perhaps should first attempt to use
the size of the video that is played (no scaling).

ff5494046a v4l2sink: special handling for cases gst_buffer_make_metadata_writable()
Special case check for sub-buffers:  In certain cases, places like
GstBaseTransform, which might check that the buffer is writable before copying
metadata, timestamp, and such, will find that the buffer has more than one
reference to it.  In these cases, they will create a sub-buffer with an offset=0
and length equal to the original buffer size.

This could happen in two scenarios: (1) a tee in the pipeline, and (2) because
the refcnt is incremented in gst_mini_object_free() before the finalize function
is called, and decremented after it returns..  but returning this buffer to the
buffer pool in the finalize function, could wake up a thread blocked in
_buffer_alloc() which could run and get a buffer w/ refcnt==2 before the thread
originally unref'ing the buffer returns from finalize function and decrements
the refcnt back to 1!

This is related to issue #545501

c3721534c9 v4l2: fix race condition
The size of the buffer would be zero'd out in gst_v4l2_buffer_finalize()
after the buffer is qbuf'd or pushed onto the queue of available buffers..
leaving a race condition where the thread waiting for the buffer could awake
and set back a valid size before the finalizing thread zeros out the length.
This would result that the newly allocated buffer has length of zero.

417b899c44 v4l2sink: fix for PAUSED->READY->PAUSED state transitions
When v4l2sink goes to PAUSED->READY it only stops streaming, so the state
should be set to STATE_PENDING_STREAMON in case the element transitions
back to PLAYING.

0cec72b97e v4l2sink: Add support for blocking dequeue.
We'd prefer to throttle the decoder if we run out of buffers, to keep a bound
on memory usage.  Also, for OMAP4 it is a requirement of the decoder to not
alternate between memory alloced by the display driver and malloc'd userspace
memory.

ecfbaf58a5 v4l2: clear flags before reusing buffer from buffer pool
note: this really only affects v4l2sink since gst_v4l2_buffer_pool_get() is
only called once per buffer in the v4l2src case (in
gst_v4l2src_buffer_pool_activate())

e24cfa7250 v4l2sink: don't render preroll buffers
Most v4l2 drivers will get upset when you queue the same buffer twice in a
row without first dequeueing it.

Rendering of pre-roll buffers can be re-introduced later, but will require
tracking the state of the buffer, and avoiding to re-QBUF if the buffer has
already been passed to the driver.

48a8b53bdd v4l2sink: Improve behavior for shared buffers.
When the decoder is using pad_alloc(), v4l2sink would behave badly if
the number of buffers ('queue-size' property) was not high enough to
account for all the buffers needed by the decoder, and other elements
(such as queues) between the decoder and v4l2sink.  This patch
slightly increases the default number of buffers, and changes v4l2sink
to drop frames rather than return an error in case the number of
buffers is not high enough.

96830324a5 rtspsrc: serialise/deserialise floats without changing locale
Use g_ascii_dtostr() and g_ascii_strtod() to serialise/deserialise
floating point numbers, instead of ugly hacks that switch locale
before and after calling libc functions (which is not a good idea
in a multi-threaded application).

fafd0b7bc3 rtpjpegdepay: fix framerate parsing for locales that use a comma as floating point
atof() converts strings according to the current locale, but the
framerate string will likely always use a dot as floating point
separator, so use g_ascii_strtod() instead (but also canonicalise
the string before, so we can handle both formats as input).

1d74f568a3 matroskademux: Don't use gst_pad_alloc_buffer()
Using this in a demuxer will cause deadlocks if there's
a pad with a pending pad-block downstream, no matter if
there is a queue between the pad or not. Queues pass
bufferalloc downstream from the same thread and only
act as a thread boundary for events and buffers.

dcbba0932d jpegenc: sink pad's getcaps shouldn't use the src pad getcaps
Instead of using get_allowed_caps on the srcpad, the sinkpad getcaps
should use the getcaps of the srcpad's peer. This way the srcpad
can keep using fixed_caps and sinkpad getcaps exposes all caps
that can be negotiated
