So we don't crash when a muxer tries to add tags from two
threads at the same time, eg. because it received tag events
on two input pads simultaneously.
See #619533.
We need to check the pad caps on the srcpad as well as on the sinkpad. Revert
this commit as it removes the check on the srcpad and can leave the srcpad
unnegotiated (or negotiated with wrong caps)
This reverts commit 07dc1e5b49.
Adds 3 new geo location tags involving direction and
movement of capture. Those are:
API: GST_TAG_GEO_LOCATION_CAPTURE_DIRECTION
API: GST_TAG_GEO_LOCATION_MOVEMENT_DIRECTION
API: GST_TAG_GEO_LOCATION_MOVEMENT_SPEED
Fixes#617223
Adds those new tags to describe the device manufacturer and
model used to create medias.
API: GST_TAG_DEVICE_MANUFACTURER
API: GST_TAG_DEVICE_MODEL
Fixes#615941
Make sure we execute the same code path in git versions and in releases,
so just warn when metadata isn't writable when we want it to be instead
of bailing out.
People often call
gst_caps_make_writable (caps);
instead of
caps = gst_caps_make_writable (caps);
and cause a bug. Warning about an unused return value helps here.
See https://bugzilla.gnome.org/show_bug.cgi?id=616541#c2 for an example.
This way people can just #define their own custom flow returns to
one of these without having the compiler (esp. gcc-4.5) complain
about comparing integers to an enum or the enum not being listed
Fixes#615880.
API: GST_FLOW_CUSTOM_SUCCESS_1
API: GST_FLOW_CUSTOM_SUCCESS_2

When an element is removed from a bin because it caused a state change error,
don't unref the child twice.
Add some more debug info.
Add a unit test for this error.
Fixes#615756
Fix 'grammar.tab.c:815:6: warning: "YYENABLE_NLS" is not defined'
compiler warning and the same for YYLTYPE_IS_TRIVIAL. The two
translated strings aren't particularly helpful, so just define
YYENABLE_NLS to 0.
Point g-ir-scanner to the .la file of our library, which hopefully
makes it find the right dependencies in all cases (ie. our locally
built libgstreamer and not the system-installed one). This is also
how it's done in Gtk+ and how it's documented in the wiki, see
http://live.gnome.org/GObjectIntrospection/AutotoolsIntegration
Based on patches by Vincent Untz and Alan Knowles.
Fixes#603710.
Adds a new tag for user favorite media rating.
User rating informs how much (from 0 to 100) a user
'likes' a media.
Having an percent uint range for this is easy to map into other scales,
like some players that allow users to attribute 'stars' to its
media.
API: GST_TAG_USER_RATING
Fixes#520697
Use gst_element_class_set_details_simple() instead. If you want to
convert automatically, here's a script:

Right now deleyed set would only try for first set of children. We need to keep
trying to support arbitrary deep hierarchies (like in playbin2 with auto*sinks).
Also GstBin would need to actualy emit the child-added/removed signal as it
implements the iface. Fixes#613215.
prctl is supposed to take 5 arguments. It used to work with 2 arguments on some
versions of libc because it is defined as a varags function there.
See #611911
This either must never happen (which makes sense in this case) and thus should
use assert() or we should use a traditional if (poll_data->message) return;
to avoid differnet behaviour of intenal api when compiling with
G_DISABLE_CHECKS.
This avoids creating empty caps and destroying them in the case of an error. We
also avoid double checking in other code path where we call the internal api.
See 8fe63000de for why having a TRUE/FALSE
return value is a bad idea.
I've scanned a few plugins and they generally get it wrong and aren't
unloadable when they return FALSE.
This is what can happen in a plugin_init function:
- An element based on GstBaseSink is registered
- Other elements fail to register
- The plugin_init function returns FALSE
Now if this the plugin is the first plugin to link against
libgstbase.so, it will have caused libgstbase.so to be loaded and static
strings from that library will have been added to gobject while
registering GstBaseSink.
So unloading the plugin will cause those strings to go stale and the
next plugin using GstBaseSink will crash. So we must not unload modules
after calling into them ever.

This brings total call speedups between 5% and 25%.
gst_caps_set_simple_valist: +5%
gst_structure_set_valist: + 10%
gst_structure_id_set_valist: +25%
gst_tag_list_add_valist: +5%
Measured using valgrind when run over the discovery of 200 media files.

The alignment guaranteed by malloc is not always sufficient. E.g. vector
instructions or hardware subsystems want specifically aligned buffers. The
attached patch will use posix_memalign if available to allocate buffers.
The desired alignment can be set when running configure using the new
--with-buffer-alignment option.
This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.
https://bugzilla.gnome.org/show_bug.cgi?id=611692
Adds that warning to configure.ac
Includes a tiny change of the GST_BOILERPLATE_FULL() macro:
The get_type() function is no longer declared before being defined.
