41f83d0bab README: updates. 
Mention codecparsers-based decoders, FFmpeg is now optional. Update
list of support HW.

fe791efc28 decoder: allocate proxy surface earlier. 
This simplifies gst_vaapi_picture_output() to only update the presentation
timestamp and submit the proxy to the decoder for output.

399875ee86 decoder: fix memory leak of VA objects on exit. 
On sequence end, if the last decoded picture is not output for rendering,
then the proxy surface is not created. In this case, the original surface
must be released explicitly to the context.

11d09495ea mpeg2: use GstAdapter to track input sequence. 
This fixes possible memory leaks and improves performance by removing
some extra copies.

a79c7f9fa6 decoder: optimize slice data buffers initialization. 
VA drivers may have a faster means to transfer user buffers to GPU
buffers than using memcpy(). In particular, on Intel Gen graphics, we
can use pwrite(). This provides for faster upload of bitstream and can
help higher bitrates.

vaapi_create_buffer() helper function was also updated to allow for
un-mapped buffers and pre-initialized data for buffers.

425060a7a8 h264: fix pred_weight_table() reconstruction. 
Only the explicit pred_weight_table(), possibly with the inferred default
values, shall be required. e.g. don't fill in the table if weighted_pred_flag
is not set for P/SP slices.

4a46b5d6c4 decoder: retain proxy surface until the GstVaapiPicture is destroyed. 
Keep a valid reference to the proxy in GstVaapiPicture so that frames
marked as "used for reference" could be kept during the lifetime of the
picture. i.e. don't release them too soon as they could be re-used right
away.

2897618b85 decoder: properly reference count pictures. 
This fixes cases where a GstVaapiPicture would be destroyed whereas
there is still a valid instance of it in either prev, current or
next picture.

7b19745141 decoder: simplify output of decoded frames. 
Drop obsolete gst_vaapi_decoder_push_surface() that was no longer used.
Change gst_vaapi_decoder_push_surface_proxy() semantics to assume PTS
is already set correctly and reference count increased, if necessary.

e5d12e8853 decoder: rework the internal VA objects API. 
The new API simplifies a lot reference counting and makes it more
flexible for future additions/changes. The GstVaapiCodecInfo is
also gone. Rather, new helper macros are provided to allocate
picture, slice and quantization matrix parameter buffers.

b963ccb929 profile: match video/x-h263 as H.263 Baseline profile. 
HACK: qtdemux does not report profiles for H.263. So, assume plain
"video/x-h263" is H.263 Baseline profile.

0f511e1e0b surface: don't expose gst_vaapi_surface_get_parent_context(). 
gst_vaapi_surface_get_parent_context() was not meant to be exposed globally.
It's just an internal helper function. However, it's still possible to get
the parent context through the "parent-context" property.
