c957823e8a display: cope with new display cache API. 2013-05-27 16:07:15 +02:00
Gwenole Beauchesne
b59445b2ab display: rework display cache API.
Simplify display cache API, while making it more flexible. We can now create
custom lookup functions with gst_vaapi_display_cache_lookup_custom().

67eea92044 libs: drop GST_VAAPI_IS_xxx() helper macros.
Drop obsolete GST_VAAPI_IS_xxx() helper macros since we are no longer
deriving from GObject and so those were only checking for whether the
argument was NULL or not. This is now irrelevant, and even confusing
to some extent, because we no longer have type checking.

Note: this incurs more type checking (review) but the libgstvaapi is
rather small, so this is manageable.

c2abeb1290 libs: simplify GstVaapiID definitions.
Make GstVaapiID a gsize instead of guessing an underlying integer large
enough to hold all bits of a pointer. Also drop GST_VAAPI_ID_NONE since
this is plain zero and that it is no longer passed as varargs.

Port GstVaapiDecoder and GstVaapiDecoder{MPEG2,MPEG4,JPEG,H264,VC1} to
GstVaapiMiniObject. Add gst_vaapi_decoder_set_codec_state_changed_func()
helper function to let the user add a callback to a function triggered
whenever the codec state (e.g. caps) changes.

Port GstVaapiVideoPool, GstVaapiSurfacePool and GstVaapiImagePool to
GstVaapiMiniObject. Drop gst_vaapi_video_pool_get_caps() since it was
no longer used for a long time. Make object allocators static, i.e.
local to the shared library.

6439169db5 libs: refine GstVaapiMiniObject.
Drop support for user-defined data since this capability was not used
so far and GstVaapiMiniObject represents the smallest reference counted
object type. Add missing GST_VAAPI_MINI_OBJECT_CLASS() helper macro.

Besides, since GstVaapiMiniObject is a libgstvaapi internal object, it
is also possible to further simplify the layout of the object. i.e. merge
GstVaapiMiniObjectBase into GstVaapiMiniObject.

da2493f731 decoder: update picture size from the bitstream.
Propagate the picture size from the bitstream to the GstVaapiDecoder,
and subsequent user who installed a signal on notify::caps. This fixes
decoding of TS streams when the demuxer failed to extract the required
information.

c43a2d497a decoder: add gst_vaapi_decoder_get_frame_with_timeout().
Add gst_vaapi_decoder_get_frame_with_timeout() helper function that will
wait for a frame to be decoded, until the specified timeout in microseconds,
prior to returning to the caller.

This is a fix to performance regression from 851cc0, whereby the vaapidecode
loop executed on the srcpad task was called to often, thus starving all CPU
resources.

851cc000c2 vaapidecode: rework GstVideoDecoder::handle_frame() with a task.
Rework GstVideoDecoder::handle_frame() to decode the current frame,
while possibly waiting for a free surface, and separately submit all
decoded frames from a task. This makes it possible to pop and render
decoded frames as soon as possible.

2909d0229d decoder: fix GstVideoCodecFrame flags for interlaced contents.

propagate GstVaapiSurfaceProxy frame flags to GstVideoCodecFrame flags
correctly.

This is a regression from commit 87e5717.

2ac474b207 decoder: export presentation timestamp for raw decoding mode.

87e5717f66 decoder: use new GstVaapiSurfaceProxy utility functions.
Use new GstVaapiSurfaceProxy internal helper functions to propagate the
necessary GstVideoCodecFrame flags to vaapidecode (GStreamer 0.10).

Also make GstVaapiDecoder push_frame() operate similarly to drop_frame().
i.e. increase the GstVideoCodecFrame reference count in push_frame rather
than gst_vaapi_picture_output().

c7dff071c7 surfaceproxy: add more attributes for raw decoding modes.

libgstvaapi helper library. In particular, add presentation timestamp,
duration and a couple of flags (interlaced, TFF, RFF, one-field).

8cce65c6f1 decoder: fix gst_vaapi_decoder_get_codec_state().
Fix previous commit whereby gst_vaapi_decoder_get_codec_state() was
supposed to make GstVaapiDecoder own the return GstVideoCodecState
object. Only comment was updated, not the actual code.

1790823ed4 decoder: make gst_vaapi_decoder_get_codec_state() return the original state.
Make gst_vaapi_decoder_get_codec_state() return the original codec state,
i.e. make the GstVaapiDecoder object own the return state so that callers
that want an extra reference to it would just gst_video_codec_state_ref()
it before usage. This aligns the behaviour with what we had before with
gst_vaapi_decoder_get_caps().

This is an ABI incompatible change, library major version was bumped from
previous release (0.5.2).

9b981dd244 plugins: fix description for gst-inspect.
Fix the name of the plug-in element reported to gst-inspect-1.0. i.e. we
need an explicit definition for GStreamer >= 1.0 because the GST_PLUGIN_DEFINE
incorrectly uses #name for creating the plug-in name, instead of using macro
expansion (and let further expansion of macros) through e.g. G_STRINGIFY().

51151e7aa1 Add initial support for GStreamer 1.0.
This integrates support for GStreamer API >= 1.0 only in the libgstvaapi
core decoding library. The changes are kept rather minimal here so that
the library retains as little dependency as possible on core GStreamer
functionality.

6e82da1e93 decoder: delegate surface size check to VA context reset.
Now that the surface pool is reference counted in the surface proxy wrapper,
we can safely ignore surface size checks in gst_vaapi_decoder_ensure_context().
Besides, this check is already performed in gst_vaapi_context_reset_full().

e22a863084 decoder: simplify acquisition/release of spare surface.
Introduce gst_vaapi_surface_proxy_new_from_pool() to allocate a new surface
proxy from the context surface pool. This change also makes sure to retain
the parent surface pool in the proxy.

Besides, it was also totally useless to attach/detach parent context to
VA surface each time we acquire/release it. Since the whole context owns
all associated VA surfaces, we can mark this as such only once and for all.

then allow the frame to be gracefully dropped without generating

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.

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.

d69cb4389f vc1: review and report errors accordingly.
Use GST_ERROR() to report real errors instead of hiding them into
GST_DEBUG().

b134a97d42 vc1: don't create GstBuffers for all decoder units.
Don't create temporary GstBuffers for all decoder units, even if they
are lightweight "sub-buffers", since it is not really necessary to keep
the buffer data around.

1513f52fc1 vc1: implement {start,end}_frame() hooks.
Implement GstVaapiDecoder.start_frame() and end_frame() semantics so
that to create new VA context earlier and submit VA pictures to the
HW for decoding as soon as possible. i.e. don't wait for the next
frame to start decoding the previous one.

823f16d7ce vc1: fix next POC for new sequence layers.
Fix next POC when a new sequence layer is reached. At this point, we
need to reset any previous reference picture, i.e. non B-frame.

472f3473e0 vc1: port to common GstVaapiDpb interface.
Use GstVaapiDpb interface instead of maintaining our own prev and next
picture pointers. While doing so, try to derive a sensible POC value.

b24752da4f decoder: simplify gst_vaapi_decoder_get_surface().
Avoid extraenous branches, i.e. immediately return with success once we
have a decoded frame available.

a811a5de3d decoder: optimize and clean decode_step() up.
Avoid usage of goto. Simplify decode_step() process to first accumulate all
pending buffers into the GstAdapter, and then parse and decode units from
that input adapter. Stop the process once a frame is fully decoded or an
error occurred.

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.

Move GstVaapiDpbMpeg2 API to a more generic version that could also be
useful to other decoders that require 2 reference pictures, e.g. VC-1.
