a6bcd09b6c decklinkaudiosink: Start scheduled playback when going to PLAYING
The ringbuffer's acquire() is too early, and ringbuffer's start() will only be
called after the clock has advanced a bit... which it won't unless we start
scheduled playback.

22b0a4dad5 decklink{audio,video}src: Take the capture times from the pipeline clock
Not from the decklink clock. Both will return exactly the same time once the
decklink clock got slaved to the pipeline clock and received the first
observation, but until then it will return bogus values. But as both return
exactly the same values, we can as well use the pipeline clock directly.

83e5fe2f70 openslesringbuffer: Only pre-roll a single buffer
There is no reason to pre-roll more buffers here as we have our own ringbuffer
with more segments around it, and we can immediately provide more buffers to
OpenSL ES when it requests that from the callback.

Pre-rolling a single buffer before starting is necessary though, as otherwise
we will only output silence.

Lowers latency a bit, depending on latency-time and buffer-time settings.

141fb455e8 openslesringbuffer: Allocate at most 4 internal buffers
4 is the "typical" number of buffers defined by Android's OpenSL ES
implementation, and its code is optimized for this. Also because we
have our own ringbuffer around this, we will always have enough
buffering on our side already.

Allows for more efficient processing.

bd5e9a5442 ksvideosrc: Fix buffer handling
The pseudo buffer pool code was using gst_buffer_is_writable()
alone to try and figure-out if cached buffer could be reused.
It needs to check for memory writability too. Also check map
result and fix map flags.

f577b52e5d applemedia: rework GL texture sharing
Use YUV instead of RGB textures, then convert using the new apple specific
shader in GstGLColorConvert. Also use GLMemory directly instead of using the
GL upload meta, avoiding an extra texture copy we used to have before.

8734abb1ce applemedia: don't call CVPixelBufferLockBaseAddress when doing texture sharing
When doing texture sharing we don't need to call CVPixelBufferLockBaseAddress to
map the buffer in CPU. This cuts about 10% relative cpu time from a vtdec !

4eb5cd9156 decklink{audio,video}sink: Only start scheduled playback once both sources are ready and we are in PLAYING
Otherwise we might start the scheduled playback before the audio or video streams are
actually enabled, and then error out later because they are enabled to late.

We enable the streams when getting the caps, which might be *after* we were
set to PLAYING state.

199ce92474 Remove unported directdraw plugin
This API has been deprecated for eternities and microsoft
stopped shipping the headers in 2010 accoding to wikipedia,
so let's just remove it and focus on bringing the plugins

d2e309d341 decklinkvideosink: Get our own "start time" instead of the one of the pipeline
decklinkvideosink might be added later to the pipeline, or its state might
be handled separately from the pipeline. In which case the running time when
we (last) went into PLAYING state will be different from the pipeline's.

However we need our own start time to tell the Decklink API, which running
time should be displayed at the moment we go to PLAYING and start scheduled
rendering.
