Fix up videorate test for latest videotestsrc changes: just check for
the important bits in the negotiated caps, not for exact equality with
our filter caps. Also don't leak the videorate element in the test.
Right now this mostly demonstatest what not works. That is seeking with
start-type = NONE to only update the rate and playing backwards. Also
it shows that non-flushing seeks tend to lockup adder. Separate unit tests
for the issues follow.
XMP metadata can be embedded in many media container formats. Implement own
parser and formatter that can be used to convert between an xpacket and a
GstTagList. Add unit tests.
Also set a title in the qt examples like it is now done in the gtk example.
Fix the newly added find_video_sink in the gtk example and add similar function
to the qt examples.
Try to find a working videosink, don't hardcode xvimagesink. Also
add some borders to window and give it a title so that it's clear
that this is really a Gtk+ window and not a window created by the
videosink.
Add simple videotestsrc ! xvimagesink examples using gtk and qt. This patch also
adds all boilerplate to configure for using c++. The qt based examples are
optional like their gtk counterparts.
The only difference between the two unit tests right now is,
that the decodebin2 test resets the element to READY before trying
to reuse it instead of NULL. decodebin2 guarantees to be reusable
without going back to NULL.
Add some utility functions for language tags and ISO-639
codes. These are useful for both GUIs and elements. The
iso-codes package is used for language name translations
if available.
API: gst_tag_get_language_codes()
API: gst_tag_get_language_name()
API: gst_tag_get_language_code()
API: gst_tag_get_language_code_iso_639_1()
API: gst_tag_get_language_code_iso_639_2B()
API: gst_tag_get_language_code_iso_639_2T()
Add a new video event to mark the start or end of a still-frame
sequence, and a parser function to identify and extract info from
such events.
API: gst_video_event_new_still_frame()
API: gst_video_event_parse_still_frame()
Fixes: #601942
This completes the deprecated GTK API fix in commits 81a0a986 and
79adfa54 - unlike gtk_signal_connect and co, g_signal_connect and
co take a gpointer, not a GtkObject.
the uninstalled wrapper would create a LD_LIBRARY_PATH with system-wide
path before the local ones... resulting in the example applications picking
up the system-wide libraries and not the (potentially modified) uninstalled
libraries
