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.
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.
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 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.
When we unblock a pad with the same user_data, the destroy callback is not
called. This leads to refcounting leaks that cannot be avoided. Instead always
call the destroy notify whenever we install a new pad block.
In particular, this fixes a nasty pad leak in decodebin2.
Also update the unit test to have more accurate comments and test the required
behaviour.
Adds the following new tags:
GST_TAG_SHOW_NAME
GST_TAG_SHOW_SORTNAME
GST_TAG_SHOW_EPISODE_NUMBER
GST_TAG_SHOW_SEASON_NUMBER
GST_TAG_LYRICS
GST_TAG_COMPOSER_SORTNAME
GST_TAG_GROUPING
Fixes#599759
Setting an object name is nice for proper debug logging. Ideally this would
still happens earlier (.e.g when pads are added to an element, its not yet set).
Never skip the state change to playing, even if the element is already in the
right state. We need this because we also distribute the base_time while doing
the state change and skipping this step would leave some elements without a new
base_time.
Fixes#600313
gst_value_list_size and gst_value_list_get_value will do a series of
extra checks due to being public methods.
When we use them from within gstvalue.c we can directly use them without
the extra checks.
