ab70d79c43 applemedia: vtenc: Register a hardware-only vtenc_h264_hw element on OSX
Similar to vtdec_hw, this commit adds a vtenc_h264_hw element that fails
caps negotiation unless a hardware encoder could actually be acquired.
This is useful in situations where a fallback to a software encoder
other than the vtenc_h264 software encoder is desired (e.g. to x264enc).

f6154b4cc0 applemedia: always fill GstBuffers with GstMemory
Always fill buffers with our custom memory. The custom memory will avoid
mapping CV/CM buffers unless necessary.

e0d65937bc applemedia: vtenc: accept UYVY on Mac
When doing GLMemory avfvideosrc negotiates UYVY. This change allows avfvideosrc
! tee name=t ! ... ! glimagesink t. ! ... ! gldownload ! vtenc_h264 ! ...
to do GLMemory and 0-copy with the encoder (with the CV meta).

788ff2f98e vtenc: Set profile_level to NULL after release
Otherwise, gst_vtenc_negotiate_profile_and_level will double-release as
it checks for profile_level != NULL. This caused crashes when the
vtenc instance is stopped and then restarted.

5336cc9ff6 Revert "vtenc: free input buffer ASAP"
This reverts commit 6101fc57b8.

GstVideoEncoder assumes that the input buffer is available until _finish_frame.

29c79d7595 vtenc: always enqueue frames, even on error
Even when we fail to encode frame, we should still enqueue it so
it could be passed into handle_frame (with output_buffer == NULL).
Otherwise, we risk GstVideoEncoder's queue of frames growing unbounded.

Note: We're slightly changing the renegotiation code to accommodate for
frames without output buffers, but this commit takes no ownership over
the way negotiation is being done.

6101fc57b8 vtenc: free input buffer ASAP
VTCompressionSessionEncodeFrame retains the CVPixelBuffer during
encoding, and will release it as soon as it can (e.g. before it even
calls our callback). This means we can safely release input buffer
at this point, possibly allowing the system to reuse it sooner.

5db08a8b89 vtenc: add alignment=au to sink caps

should set 'alignment=au' in sink caps to indicate this.

94e7ed1323 vtenc: fix keyframe request race condition
It is incorrect to modify the frame properties after passing them, since
VTCompressionSessionEncodeFrame takes reference and we have no control
over when it's being used.

In fact, the code can be simplified. We just preallocate the frame
properties for keyframe requests, and pass NULL otherwise.

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.

7d318a572c vtenc: Unlock the stream lock while waiting for pending frames to be completed in finish()

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.

1a2362eb2b vtenc: Fix conversion of the bitrate property and our internal bitrate storage
The property is in kbit/s and we store it in bit/s, so just multiply and
divide by 1000. No need to put a factor of 8 in there.

kVTCompressionPropertyKey_AverageBitRate is also in bit/s according to
its documentation.

68c067e3c9 vtenc: Fix locking
The object lock only protects the session, as we modify
the session from other threads when the bitrate property
is changed. Don't hold it much longer than for session
related things.

And we need to release the video decoder stream lock before
enqueueing a frames. It might wait for our callback to dequeue
a frame from another thread, which will then take the stream
lock too and deadlock.

ad649138aa vtenc: Use kVTProfileLevel_H264_Baseline_AutoLevel only on iOS
It is not required on OSX apparently and was only added in 10.9.6 there.
Calculating the correct level from the configuration is not trivial, so let's
just not set a level at all here.

3c1ccb64eb vtenc: Fix encoder to work on iOS
iOS has special stride requirements that we don't know yet, so copy
input buffers into buffers allocated by iOS for now.

Later we should check the stride and probably provide a buffer pool for these
buffers so upstream can directly write in there.

b323fba934 vtenc: Avoid leaking caps object and its copy
gst_pad_get_pad_template_caps() returns a reference which is unreferenced,
so creating a copy using gst_caps_copy() results in a reference leak. Also
the caps are pushed as an event downstream, but this doesn't consume the
caps so it must still be unreferenced.
