Thiago Santos e17d99c4c4 basecamerabinsrc: Optimize preview pipeline startup 
Use gst_element_link_pads_full to optimize preview pipeline startup,
leading to a faster camerabin2 startup as well.

Vincent Penquerc'h f3cb4439cf basevideoencoder: fix element leak 
and this concludes an hour of yelling at the bloody test failing,
only to track down the problem not being in the test.

Thiago Santos 011eddcd0e camerabin2: Remove from experimental 
Remove camerabin2 from experimental, allowing it to be built
without needing to pass --enable-experimental on configure.

Sebastian Dröge 8c743fbc0f basevideo: Fix locking, especially if both pads have different streaming threads 2011-08-18 10:23:32 +02:00
Sebastian Dröge a081501a90 basevideo: Don't call g_type_class_peek_parent() in class_init 
This is already done by the GObject boilerplate macro

Sebastian Dröge d576e23aa4 basevideoencoder: Proxy the width/height/framerate/PAR constraints of downstream caps to upstream 
This allows to specify constraints on the compressed downstream caps
by muxers or capsfilters, which will then be forwarded to upstream
and allows video converters to fulfill the constraints.

Code based on Mark Nauwelaerts audio encoder base class.

Sebastian Dröge 4a76d3a978 basevideoencoder: Remove ::get_caps() vfunc 
Subclasses can set the caps more efficiently and this only
caused additional indirections.

Sebastian Dröge 6e4e4e107c basevideodecoder: Use the cached video frame size instead of recalculating it 2011-08-09 10:43:55 +02:00
Tommi Myöhänen 9238647314 photography: add missing FLICKER_REDUCTION capability 
GstPhotography API contains functions to get/set flicker reduction
mode, but GstPhotoCaps enumeration doesn't have item for it, so elements
are not able to report whether they support this feature or not.
Also add useful GST_PHOTOGRAPHY_CAPS_ALL for easily selecting all
capabilities at once.

Raluca Elena Podiuc 058a3d9d4c basecamerasrc: remove unused get_allowed_input_caps 
The use of this method was removed in:
    commit 539f10f4d9
    basecamerasrc: More cleanup

The code from wrappercamerabinsrc is from v4l2camerasrc but is unused:
get_allowed_input_caps is not called anywhere.

Sebastian Dröge e5be8aa8ff basevideoencoder: Only get caps from the subclass if they were not set yet by the subclass 2011-07-21 08:09:11 +02:00
Sebastian Dröge b2525a3044 basevideoencoder: Delay sending of serialized sink events until finish_frame() 2011-07-21 08:09:11 +02:00
Sebastian Dröge f011e59943 basevideoencoder: Add ::reset vfunc and handle ::reset/::finish the same way as in the decoder 2011-07-21 08:09:10 +02:00
Sebastian Dröge 2dbd24ca84 basevideoencoder: Use a temporary GstVideoState until the subclass accepted the caps 
Also store the caps in the GstVideoState and assume a PAR of 1/1 instead
of 0/1 if no PAR is specified in the caps.
 2011-07-19 12:52:31 +02:00
Sebastian Dröge 83c4e8814e basevideodecoder: First inform subclass about resetting before resetting/freeing all internal state 
The subclass might want to access the old state.

Sebastian Dröge a59246c1d1 basevideodecoder: Track present position on discont before resetting it 2011-07-11 12:36:42 +02:00
Sebastian Dröge 08823f80d6 basevideodecoder: Also protect the list of pending frames from concurrent access when pushing all pendings events 2011-07-11 11:52:48 +02:00
Sebastian Dröge 81f4c9e8bf basevideocodec: Protect access to the list of pending frames with the object lock 
This is required if ::finish_frame() and all buffer output happens
on a different thread than the sinkpad streaming thread.

Sebastian Dröge caed64c720 basevideodecoder: Set the correct lists to NULL after freeing 2011-07-11 09:35:25 +02:00

Also fix a refcount problem with the codec_data.

Sebastian Dröge e61d3d1a0c basevideo: Move the utils from the codec header to its own header 2011-07-09 11:40:17 +02:00
Sebastian Dröge 5f55a74571 basevideo: Use GSlice for allocating GstVideoFrame and don't duplicate code in the decoder base class 2011-07-09 11:09:12 +02:00
Sebastian Dröge f341386b64 basevideodecoder: Don't reorder serialized src events 
And allow to drop EOS by the subclass if ::finish returns
DROPPED. This requires that the subclass sends EOS manually later.

Fixes bug #653544.

Sebastian Dröge 525875727a basevideo: Add the caps to the GstVideoState and clean up caps/codec_data properly 
Having access to the caps in ::set_format can be useful if
non-standard caps fields like the h264 alignment must be accessed.
 2011-07-09 11:02:01 +02:00
Sebastian Dröge fc93c66d3b basevideo: Add destroy notify for the coder_hook to prevent memory leaks

Lauri Lehtinen c86d662b23 basecamerabinsrc: Handle errors from preview pipeline 
Implements a message handling function to preview pipeline bus.
If GST_MESSAGE_ERROR is seen, considers preview pipeline unable
to do its job and posts an error message to application.

Sets pipeline element to NULL so that subsequent calls to post_preview
and set_caps functions just returns without pushing anything to the
disposed preview pipeline. Leaves further actions to the application.

Lauri Lehtinen 802028081c basecamerabinsrc: Protection for previewpipeline when setting new preview caps 
Implements a state indicating flag to preview pipeline,
so that new caps are not set if the pipeline is processing a
preview. The caps are set as pending and applied when the
next preview post is called.

In this case a wait was implemented in the post_preview function,
so that new preview image buffer will wait until the other previews
have been posted to the application and the new caps can be used
safely.

 2011-05-16 20:32:24 +02:00
Mark Nauwelaerts 380a443be4 basevideodecoder: video state reference to codec_data is not refcounted 
... but rather implicitly valid as long as sink caps are not modified.
 2011-05-16 20:32:24 +02:00
Mark Nauwelaerts a1825bd5e2 basevideodecoder: improve glitch resilience 
Provide a replacement for GST_ELEMENT_ERROR to avoid aborting at the first
atom out of place, while on the other hand not failing indefinitely.

Mark Nauwelaerts 1b151caf11 basevideodecoder: really and only set src pad caps whenever requested 
... since subclass is expected to be wise enough to know when to do so.
 2011-05-16 20:32:23 +02:00
Mark Nauwelaerts 550237347b basevideodecoder: add some sanity enforcing 2011-05-16 20:32:23 +02:00
