Alessandro Decina b6747292e0 qtkitvideosrc: get the framerate from caps 
...and configure QTKit accordingly. Hardcoding to 30fps was pretty -bad.

Ole André Vadla Ravnås f3d8e3920d applemedia: only enqueue buffers in the VideoToolbox callbacks 
These callbacks may fire from any thread, hence we should only enqueue
buffers and let the streaming thread take care of the rest as soon as
the blocking encode or decode operation has finished.
 2010-12-10 04:07:05 +01:00
Ole André Vadla Ravnås f7e5878c9e applemedia: bring back Leopard compatibility 
At least as far as miovideosrc is concerned. Turns out that CoreVideo's
CVPixelBufferGetIOSurface is not present in Leopard's version of CoreVideo.
We solve this by making it possible for symbols to be marked as optional.
 2010-12-10 04:06:59 +01:00
Alessandro Decina 0b6e0b7b13 qtkitvideosrc: reset the queue condition to NO_FRAMES in unlockStop. 
Fixes a segfault in create: when going PLAYING -> PAUSED -> PLAYING.
 2010-12-09 12:04:10 +01:00
Alessandro Decina ec6c307334 qtkitvideosrc: run the mainRunLoop for a while if not running. 
QTCaptureSession::addInput and QTCaptureSession::addOutput call
NSObject::performSelectorOnMainThread internally so they need the mainRunLoop to
run at least for a while to complete.
 2010-12-09 11:55:57 +01:00
Alessandro Decina 536a30f2df applemedia: don't use the deprecated g_strcasecmp function. 
Replace g_strcasecmp with g_ascii_strcasecmp.

Alessandro Decina aae72680bd Fix compiler warnings with gcc 4.2.1 on OSX. 2010-12-01 23:20:36 +01:00
Ole André Vadla Ravnås abdb30c567 celvideosrc: fix nasty deadlock 
We cannot call any CMBufferQueue functions while holding the lock that
our callback also depends on. So now we make use of CMBufferQueue's
trigger API in order to get notified when the queue has data.
 2010-11-12 00:44:42 +01:00
Ole André Vadla Ravnås de76e9fdb6 cmapi: cover CMBufferQueue's trigger API 2010-11-12 00:44:42 +01:00
Ole André Vadla Ravnås e4db4257d5 celvideosrc: unlock should also notify 
Otherwise we depend on being woken up by the CoreMedia queue getting
its next buffer.
 2010-11-12 00:44:42 +01:00
Ole André Vadla Ravnås ebd2a6d6e9 applemedia: don't push synchronously from callback 
The codec that called us might be holding locks to shared resources, so
we should never push downstream from within its buffer callback.

Note that a GstBufferList is not used here because we need to preserve
the buffer metadata held by our GstBuffer subclasses.

Ole André Vadla Ravnås 6b63954f63 vtenc: bump H.264 level from 1.3 to 3.0 
This should be turned into a property.
 2010-11-11 00:22:31 +01:00
Ole André Vadla Ravnås 6e909dc474 celvideosrc: add basic device selection support 2010-11-11 00:22:31 +01:00
Ole André Vadla Ravnås 2382f10b98 cvapi: add wrapper for IO surface access 
To be used in a future video sink for zero-copy rendering.
 2010-11-11 00:22:31 +01:00
Ole André Vadla Ravnås 420943972c celapi: add capture port type constants 2010-11-11 00:22:31 +01:00
Ole André Vadla Ravnås d10e029f51 applemedia: biplanar is actually NV12, not I420 
D'oh!
 2010-11-08 23:58:25 +01:00
Ole André Vadla Ravnås d865feca82 vtenc: remove keyframe enforcement workaround 
Was only needed for old iOS where the H.264 encoder didn't support
kVTEncodeFrameOptionKey_ForceKeyFrame.
 2010-11-08 23:58:25 +01:00
Ole André Vadla Ravnås abba3a4126 cvapi: add a few extra bits of wrapping 2010-11-08 23:58:25 +01:00
Ole André Vadla Ravnås b4654f537f applemedia: lock CVPixelBuffer read-only 
As per Apple's docs, this may improve performance by avoiding redundant
invalidations of existing caches of the buffer contents.
 2010-11-08 23:58:24 +01:00
Ole André Vadla Ravnås 6428d306ea celvideosrc: put planar first in template caps 2010-11-08 14:02:50 +01:00
Ole André Vadla Ravnås c2672f71cd applemedia: improve vtenc/vtdec performance 
Profiling of H.264 encode and decode revealed that conversions
between packed and planar were happening behind the scenes.

Hence we now choose I420 instead of YUY2.
 2010-11-08 14:02:50 +01:00
Ole André Vadla Ravnås 1eb9190ad9 celvideosrc: measure fps when statistics is enabled 
Also refactor timestamping slightly.
 2010-11-05 16:52:58 +01:00
Ole André Vadla Ravnås b7368c34fd celvideosrc: update to new Celestial and MediaToolbox APIs

 2010-11-05 15:32:37 +01:00
Ole André Vadla Ravnås bf095e891f celvideosrc: fix debug category description 2010-11-05 15:32:37 +01:00
Ole André Vadla Ravnås 517f3a75c2 celapi: update to reflect new API on iOS 4.x

This is in order to improve consistency with the other three sources.
 2010-11-04 19:27:25 +01:00
Ole André Vadla Ravnås 8b22f855ec avfvideosrc: don't explicitly empty the buffer queue 
We're holding the only reference to it so there's no need to explicitly
empty it right before letting go of our reference.
 2010-11-04 17:58:59 +01:00
Ole André Vadla Ravnås 89e5b60130 avfvideosrc: make buffer offset start from zero 2010-11-04 17:52:05 +01:00
Ole André Vadla Ravnås 86e2539816 qtkitvideosrc: implement zero-copy by using buffer-factory 
This means we'll wrap each CoreVideo buffer inside a GstBuffer instead of
making a copy.
 2010-11-04 17:52:05 +01:00
Ole André Vadla Ravnås 835b2988b6 bufferfactory: add support for wrapping CVBuffer 2010-11-04 17:52:05 +01:00
