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.

5496fd3e75 avfvideosrc: improve timestamp code 
Use a combination of the running time and CMClockGetTime from AVF to compute
timestamps.

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.

0156725480 avfvideosrc: improve timestamping and latency reporting 
Use AVF provided timings to timestamp output buffers. Use the running time at
the time the first buffer is produced to base timestamps on. Report 1-frame
latency based on the negotiated framerate instead of hardcoding 4ms latency.

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.

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.
