e539092f21 tests: modernize GstTypeFind functions.
Use the GstTypeFind hooks from GStreamer 1.0. They look safer and
exactly correspond to the expected behaviour.

0ad846e68d subpicture: use gst_video_overlay_rectangle_get_pixels_unscaled_raw().
Use newer gst_video_overlay_rectangle_get_pixels_unscaled_raw() helper
function with GStreamer 0.10 compatible semantics, or that tries to
approach the current meaning. Basically, this is also just about moving
the helper to gstcompat.h.

bd3aa01de5 build: fix compiling of local GstVideoDecoder and codecparsers.
Generated source files were missing a dependency on the complete set of
generated header files. e.g. gstvideodecoder.c requires gstvideoutils.h
to build and almost every codec parser source depends on parserutils.h.

ddaaa42020 h264: set {luma,chroma}_log2_weight_denom to 0 if no pred_weight_table().
Force luma_log2_weight_denom and chroma_log2_weight_denom to zero if
there is no pred_weight_table() that was parsed.

This is a workaround for the VA intel-driver on Ivy Bridge.

564ca5d221 mpeg2: fix decoding of sequence_end().
There shall be only one place to call decode_current_picture(), and this
is in the end_frame() hook. The EOS unit is processed after end_frame()
so this means we cannot have a valid picture to decode/output at this
point.

23b2386fd0 mpeg2: improve robustness when packets are missing.
Improve robustness when some expected packets where not received yet
or that were not correctly decoded. For example, don't try to decode
a picture if there was no valid sequence or picture headers.

4499f39274 decoder: handle decode-only frames in raw API mode.
Fix gst_vaapi_decoder_get_surface() to only return frames with a valid
surface proxy, i.e. with a valid VA surface. This means that any frame
marked as decode-only is simply skipped.

2305b0db46 decoder: allow frames to be dropped.
If the decoder was not able to decode a frame because insufficient
information was available, e.g. missing sequence or picture header,
then allow the frame to be gracefully dropped without generating
any error.

It is also possible that a frame is not meant to be displayed but
only used as a reference, so dropping that frame is also a valid
operation since GstVideoDecoder base class has extra references to
that GstVideoCodecFrame that needs to be released.

23c6053b94 wayland: fix frame_redraw callback.
The redraw callback needs to be attached to the surface prior to the
commit. Otherwise, the callback notifies the next surface repaint,
which is not the desired behaviour. i.e. we want to be notified for
the surface we have just filled.

Another isse was the redraw_pending was reset before the actual completion
of the frame redraw callback function, thus causing concurrency issues.
e.g. the callback could have been called again, but with a NULL buffer.

087bf30c23 wayland: fix display sharing.
When the Wayland display is shared, we still have to create our own local
shell and compositor objects, since they are not propagated from the cache.
Likewise, we also need to determine the display size or vaapisink would
fail to account for the display aspect ratio, and will try to create a 0x0
window.

df411e435f vc1: fix size of encapsulated BDU.
Fix size of encapsulated BDUs since GstVC1BDU.size actually represents
the size of the BDU data, starting from offset, i.e. after any start
code is parsed.

This fixes a buffer overflow during the unescaping process.

that input adapter. Stop the process once a frame is fully decoded or an

cc347cb41e decoder: make decode_step() return once the frame is decoded.
Make sure we always have a free surface left to use for decoding the
current frame. This means that decode_step() has to return once a frame
gets decoded. If the current adapter contains more buffers with valid
frames, they will get parsed and decoded on subsequent iterations.
