If the GST_PLUGIN_SCANNER environment variable is set, we should try
the scanner specified there first, to make sure the right scanner binary
is used for uninstalled setups and builds from source when there's
already an installed version.
We require threads to be supported in any case and defining this
will simplify the mutex, condition variable, etc. macros from gthread
to not always check if threads are really supported.
Fixes bug #607481.
For the reason outlined at the beginning of gst_private.h (inline
functions in glib may need the g_log_domain variable). Also include
gst_private.h before using any G_OS_* defines, esp. in plugin loader.
This check is not necesarry as we are not negotiating anymore. And it can
be wrong if upstream can't produce this caps anymore, but downstream can
process them fine.
All callers of this static function already check for NULL-ness
themselves, so no need to do it again (and if we do it, we should
probably do so before dereferencing the pointer for the first time).
Avoid checking the GType of the value twice (once on our side and
once in g_value_get_*()) by by-passing g_value_get() and accessing
the GValue structure directly.
Fix link to gst-uninstalled now that it's been moved, and fix a typo
while we're at it. Also add a new section to 'Building GStreamer from
git' that points to the 'How do I develop against an uninstalled copy
of GStreamer' section.
Strings in the binary registry are NUL-terminated, so we can just use them
directly if we only need them temporarily, and avoid unnecessary mallocs
and frees.
Add a method to perform get_range typefinding that also uses the
uri/location extension as an extra hint. It will first try to call the
typefind functions of the factories that handle the given extension. The result
is that in the common case, we only call one typefind function, which speeds up
the typefinding a lot.
Protect the ->removed field with the object lock as well. Take the DYN lock
earlier so that we can mark the pad removed and avoid a race in pad_alloc.
Fixes#606435
No need to call gst_element_link_pads_filtered with filter=NULL, which would
call gst_element_link_pads() in that way. Call it directly to save a call and
expensive gobject type checks.
Fix up translated strings for some recently-added tags to match the
existing strings: we want short mnemonic-like strings here that start
with a lower case letter.
The only reason these two functions are still around is that at some
point in the past they were in a public header, so we can't really
remove them now even though they should have been private all along
(and aren't really particularly useful). Since these are just empty
stubs now that do nothing but return FALSE and will be removed in
0.11 anyway, we may just as well deprecate them formally.
Move SHAVE_INIT behind all other checks, in particular AG_GST_CHECK_CHECKS.
This should fix problems with header checking and checking for localtime_r,
which causes compilation errors with clean checkouts where common/shave has
not been created yet when those checks are run. It seems like SHAVE_INIT
changes the environment so that checks depending on a compiler need shave
to exist at that point, which will fail if AC_OUTPUT hasn't created it yet.
Fixes#605930.
Include unistd.h so that _POSIX_VERSION is actually defined when
it should be defined. Without that, stuff like fail_if(1) doesn't
actually fail, presumably because other parts of the code do include
unistd.h and then have _POSIX_VERSION defined.
Fixes#604565 even more.
Move the parent buffer pointer into the GstBuffer struct so that we can
remove the subbuffer class and type. This is interesting because it allows us to
more naturally implement methods to get the real type and parent
of a subbuffer (See #545501).
It should also be slightly faster because there is no extra object hierarchy to
initialize and free.
Make sure we take ownership of the buffer early without increasing its refcount
when we go in the collect function. This reduces the amount of copies needed in
order to make the buffer writable in most cases.
In some cases we can avoid allocating a subbuffer and instead simply ref
the buffer. Callers should perform _make_metadata_writable() in all
cases now.
Add a method to install a clipping function that is called when a buffer is
received. Users of collectpads can then perform clipping on the incomming
buffers.
Also retab the header file a little.
