d4d02c6f9d corevideotexturecache: Add some assertions instead of just dereferencing NULL 2015-02-03 17:32:24 +01:00

b51254395a corevideotexturecache: Don't unconditionally use the CoreMedia meta on iOS 
We might instead have a CoreVideo meta.

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 !
glimagesink pipeline.

downstream

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.

00176a1ddf decklink: Make sure our clock never returns NONE, always advances and does not jump when going from PAUSED to PLAYING 
It basically behaves the same as the audio clocks.

8a5d2c561c decklinkvideo{sink,src}: Make elements more similar to the audio elements by enabling the video input/output only when getting the actual caps 
This will also make it easier later to support caps changes and support
selecting the mode based on the caps if that should ever be implemented.

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
based on the newer APIs up to snuff.

5a12b2670e decklinkvideosink: Stop scheduled playback shortly in PAUSED->PLAYING if it was running already 
This fixes handling of flushing seeks, where we will get a PAUSED->PLAYING
state transition after the previous one without actually going to PAUSED
first.

92fa187d11 decklinkvideosink: Don't schedule too late frames in prepare() 
Otherwise we will overflow the internal buffer of the hardware
with useless frames and run into an error. This is necessary until
this bug in basesink is fixed:

7b979703f8 decklinkvideosink: Keep track of the time when we went to PLAYING for the external clock too 
Otherwise we're adding an offset of the time the pipeline was in PLAYING
already to the running time when converting it to our internal clock.

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.

4531a341a8 decklinkvideosrc: Post LATENCY message when the mode changes 
Different modes have different framerates, and thus different latencies. We
might need to reconfigure the latency of the pipeline.

7d318a572c vtenc: Unlock the stream lock while waiting for pending frames to be completed in finish() 
We might otherwise deadlock because gst_vtenc_enqueue_buffer() can be
called again and will take the stream lock again from another thread.

568da160cb vtenc: Instead of crashing if no corresponding frame is found, ignore this 
... and hope that everything will be fine. This shouldn't really happen but
previously happened during shutdown. It should be fixed in videoencoder now,
but better be on the safe side here.
