2012-11-16vc1: use framerate information from bitstream parser.Gwenole Beauchesne1-46/+5
2012-11-16vc1: use pixel-aspect-ratio from bitstream parser.Simon Farnsworth1-1/+8
Signed-off-by: Simon Farnsworth <simon.farnsworth@onelan.co.uk> Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
2012-11-16mpeg2: fix PAR calculation from commit 132922d.Sreerenj Balachandran2-5/+14
Invoke gst_mpeg_video_finalise_mpeg2_sequence_header() to get the correct PAR values. While doing so, require a newer version of the bitstream parser library. Note: it may be necessary to also parse the Sequence_Display_Extension() header.

2012-11-16mpeg2: add decode_packet() helper function.Gwenole Beauchesne1-76/+87
Split decode_buffer() into the core infrastructure that determines the packets contained in the adapter and the actual function that decodes the packet data.
2012-11-16mpeg2: fix end-of-stream conditions (flush).Gwenole Beauchesne1-6/+14
Decode pending data in the adapter prior to processing the actual code for end-of-stream. Initial code from Feng Yuan.
2012-11-16mpeg2: fix memory leak of empty packets.Gwenole Beauchesne1-12/+1
Fix memory leakage of empty packets, i.e. packets that only contain the start code prefix. In particular, free empty user-data packets. Besides, the codec parser will already fail gracefully if the packet to parse does not have the minimum required size. So, we can also completely drop the block of code that used to handle packets of size 4 (including the start code).
2012-11-16mpeg2: fix return value for "no-data" conditions.Gwenole Beauchesne1-9/+30
Fix return value when the second scan for start code fails. This means there is not enough data to determine the full extents of the current packet and the function shall return GST_VAAPI_DECODER_STATUS_ERROR_NO_DATA in this case, instead of GST_VAAPI_DECODER_STATUS_SUCCESS.
2012-11-16decoder: refine semantics of gst_vaapi_decoder_put_buffer().Gwenole Beauchesne1-2/+10
Improve the semantics for gst_vaapi_decoder_put_buffer() when an empty buffer is passed on. An empty buffer is a buffer with a NULL data pointer or with a size equals to zero. In this case, that buffer is simply skipped and the function returns TRUE. A NULL buffer argument still marks the end-of-stream.
2012-11-16decoder: drop unused functions.Gwenole Beauchesne2-38/+0

2012-11-16Fix build with the GNU gold linker.Gwenole Beauchesne1-0/+3
In particular, fix libgstvaapi-glx DSO dependencies to include libgstbase and libgstvideo libs, e.g. for gst_video_buffer_get_overlay_composition().
2012-10-05wayland: cosmetics (remove tabs).Gwenole Beauchesne2-5/+5
2012-10-05wayland: add support for windowed mode.Rob Bradford1-15/+42
Rather than always making the surface fullscreen instead implement the set_fullscreen vfunc on GstVaapiWindow and then set the shell surface fullscreen on not depending on that. Reviewed-by: Joe Konno <joe.konno@intel.com> Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
2012-09-27utils: drop unused GLX helpers.Gwenole Beauchesne2-65/+0
Remove helpers for GL_ARB_fragment_program and GL_ARB_multitexture extensions since they are not used throughout gstreamer-vaapi.
2012-09-27utils: fix build with <GL/glext.h> version >= 85.Gwenole Beauchesne1-0/+7
Mesa recently updated the <GL/glext.h> header version to Khronos version 85. This caused the PFNGLMULTITEXCOORD2FPROC definition to be moved out of the GL_VERSION_1_3_DEPRECATED block. However, since <GL/gl.h> also defines GL_VERSION_1_3 to 1, the definitions in <GL/glext.h> are then not enabled, thus leaving PFNGLMULTITEXCOORD2FPROC undefined as well. Provide a PFNGLMULTITEXCOORD2FPROC replacement as an interim solution for newer versions of the <GL/glext.h> header.
2012-09-21h264: review and report errors accordingly.Gwenole Beauchesne1-8/+8
Use GST_ERROR() to report real errors instead of hiding them into GST_DEBUG().
2012-09-20h264: exclusively use GstAdapter, drop sub-buffer hack.Gwenole Beauchesne1-39/+63
Maintaining the sub-buffer is rather suboptimal especially since we were also maintaining a GstAdapter. Now, we only use the GstAdapter thus requiring minor extra parsing when receiving avcC buffers.
2012-09-17wayland: set opaque region for YUV surface.Kristian Høgsberg1-0/+18
This allows the compositor to optimize redraws and cull away changes obscured by the video surface. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
2012-09-12glibcompat: add replacement for g_cond_wait_until().Gwenole Beauchesne1-0/+14

2012-09-11vaapidecode: don't reset decoder if codec type is the same.Gwenole Beauchesne2-0/+19
Reset, i.e. destroy then create, the decoder in _setcaps() handler only if the underlying codec type actually changed. This makes it possible to be more tolerant with certain MPEG-2 streams that get parsed to form caps that are compatible with the previous state but minor changes to "codec-data".
2012-09-11decoder: propagate buffer duration downstream.Gwenole Beauchesne1-0/+6
2012-09-11surfaceproxy: add "duration" property.Gwenole Beauchesne2-0/+73
2012-09-10decoder: cope with new GstVaapiContextInfo based API.Gwenole Beauchesne7-102/+121
Update decoders to report the maximum number of reference frames to use.
2012-09-10context: JPEG codec does not need any reference frame.Gwenole Beauchesne1-0/+1
2012-09-10context: allow number of reference frames to be set.Gwenole Beauchesne2-25/+124
Make it possible to specify the maximum number of references to use within a single VA context. This helps reducing GPU memory allocations to the useful number of references to be used.

2012-09-07Do not forward declare enums.Philip Lorenz8-42/+26
Forward declaring enums is not allowed by the C standard and aborts compilation if the header file is included in a C++ project. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>

2012-08-30display: fix GstVaapiRotation enumeration of values.Gwenole Beauchesne1-0/+1
2012-08-29vaapisink: drop obsolete GstVaapiVideoSink interface.Gwenole Beauchesne3-194/+0
This interface was deprecated since 0.3.x series when the GstVideoContext interface was added to the main GStreamer APIs.
2012-08-29display: partially revert 8ebe4d6.Gwenole Beauchesne1-10/+3
Don't try to fix up the initial values, this could make things worse. Simply assume the driver does not support the capability in this case.
2012-08-28display: fix validation process of properties during discovery.Gwenole Beauchesne1-2/+18
Some VA drivers (e.g. EMGD) can have completely random values for initial display attributes. So, try to improve the discovery process to check the initial display attribute values actually fall within valid bounds. If not, try to reset those to some sensible values like the default value reported through vaQueryDisplayAttributes().
2012-08-28display: add color balance properties.Gwenole Beauchesne2-0/+173
Add support for hue, saturation, brightness and contrast attributes.
2012-08-28display: initialize default attribute values.Gwenole Beauchesne1-1/+12
Ensure the display attribute is actually supported by trying to retrieve its current value during GstVaapiDisplay creation.
2012-08-28display: raise "notify" for property changes.Gwenole Beauchesne1-0/+4
2012-08-28display: expose display attributes as GObject properties.Gwenole Beauchesne2-5/+57
Expose VA display "render-mode" and "rotation" attributes as standard GObject properties.
2012-08-28display: install properties in batch.Gwenole Beauchesne1-36/+34
Use g_object_class_install_properties() to install GstVaapiDisplay properties. It is useful to maintain properties as GParamSpec so that to be able to raise "notify" signals by id instead of by name in the future.
2012-08-27display: fix gst_vaapi_display_has_property().Gwenole Beauchesne1-2/+18
Append the "render-mode" and "rotation" properties, should they be supported by the underlying VA driver.
2012-08-27display: add support for rotation modes.Wind Yuan7-0/+146
Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
2012-08-27display: add support for rendering modes.Gwenole Beauchesne5-0/+245
A rendering mode can be "overlay" or "texture"'ed blit. The former mode implies that a VA surface used for rendering can't be re-used right away for decoding, so the sink shall make provisions to retain the associated surface proxy until the next surface is to be displayed. The latter mode implies that the VA surface is implicitly copied to an intermediate backing store, or back buffer of a frame buffer, so the associated surface proxy can be disposed right away.
2012-08-27display: add initial support for display attributes.Gwenole Beauchesne3-2/+90
The VA display attributes are mapped to properties so that to maintain the GStreamer terminology. Properties are to be identified by name, but internal functions are available to lookup the property by the actual VA display attribute type.
2012-08-27jpeg: fix end-of-image (EOI) handler.Sreerenj Balachandran1-1/+7
decode_current_picture() was converted to return a gboolean instead of a GstVaapiDecoderStatus, so we were not getting out of the decode loop as expected, or could cause an error instead. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
2012-08-27mpeg2: include start code into VA slice data buffer.Gwenole Beauchesne1-9/+9
Integrate the start code prefix in the slice data buffer that is submitted to the hardware. VA-API specifies that slice_data_offset is the offset to the first byte of slice data. And, for MPEG-2, slice() data begins with the slice_start_code. Some VA driver implementations (EMGD) expect this.
2012-08-27decoder: use g_object_notify_by_pspec().Javier Jardón1-12/+14
Use g_object_notify_by_pspec() instead of g_object_notify() so that to avoid a property name lookup. i.e. this makes notifications faster to the `vaapidecode' element. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
