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.

83c4e8814e basevideodecoder: First inform subclass about resetting before resetting/freeing all internal state 
The subclass might want to access the old state.

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

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.

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

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.

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.

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.

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.

2f6af91f09 basevideodecoder: tune parsing sink caps into video state

380a443be4 basevideodecoder: video state reference to codec_data is not refcounted

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.

f591361d2f basevideodecoder: invoke subclass start method at state change and use set_format 
While this changes API slightly (e.g. actually uses set_format now), which is OK
for unstable API, it has following merits:
* symmetric w.r.t. stop at state change
* in line with other base class practice
* otherwise no subclass method at state change (global activation time)
Moreover, subclassese are either unaffected or trivially adjusted accordingly.

4b5623d687 basevideoencoder: invoke subclass start method at state change 
While this changes order w.r.t. set_format, which is OK for unstable API,
it has following merits:
* symmetric w.r.t. stop at state change
* in line with other base class practice
* little benefit in invoking 2 subclass virtual methods (set_format and start)
  in immediate succession; all actions in the second could be done in the first
  whereas subclass has no chance to do anything 'global' at activation time
Moreover, current -bad subclass relevant methods either trivially commute
or are either trivially adjusted accordingly.
