Use proper API to flush libass events when we do
a flushing seek, and also do it in FLUSH_STOP
rather than FLUSH_START, so we can be sure
streaming has stopped.
Fixes seeking back in time.
Something seems to have changed in libass that
renders the old manual way of flushing events
ineffective and libass then seems to ignore
timestamps that are older than the ones last
seen then if we do it the old way.
Fixes#916
With latest XDG shell, we need to fait for the surface to have been
configured before we can attach a buffer to it. This is being enforce by
Weston with an error.
Fixes#933
when computing timecode metas. Depending on the value of that flag,
n_frames is to be interpreted as a number of fields or a number of
frames. As GstVideoTimeCodeMeta always deals with frames, we want
to scale that number when needed.
The workaround for https://github.com/Intel-Media-SDK/MediaSDK/issues/1139
is required for vp8 only, so move this workaround to the corresponding
postinit_decoder function
The pipeline below works with this change
gst-launch-1.0 filesrc location=SA10104.vc1 ! \
'video/x-wmv,profile=(string)advanced',width=720,height=480,framerate=14/1 ! \
msdkvc1dec ! fakesink
MFXVideoDECODE_DecodeHeader only parses the sequence layer for VC1, so
the structure is unknown for a stream with interlace flag set in the
sequence layer. If forcing the struct to progressive in this plugin,
MediaSDK will fail to decode such streams.
This debug code will help determine why certain instances of closed
captions that are present in the Picture User Data are not actually
processed by the pipeline
Fixes the following error.

[-Werror,-Wsometimes-uninitialized]

gstccconverter.c:677:3: note: remove the 'if' if its condition is always true

It is possible MFXVideoDECODE_DecodeFrameAsync returns MFX_ERR_INCOMPATIBLE_VIDEO_PARAM
and this error can't be recovered by retrying MFXVideoDECODE_DecodeFrameAsync
in some cases, so we need to limit the number of retries to avoid infinite loop.
This fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/909
This suppresses the annoying 'g-ir-scanner: link: cc ..' output
that we get even if everything works just fine.
We still get g-ir-scanner warnings and compiler warnings if
we pass this option.
We need a nested extern in our init section for the scanner binary
so we can call gst_init to make sure GStreamer types are initialised
(they are not all lazy init via get_type functions, but some are in
exported variables). There doesn't seem to be any other mechanism to
achieve this, so just remove that warning, it's not important at all.
