vtenc_h265a

Apple VideoToolbox H265 encoder with alpha channel support. This encoder can either use HW or a SW implementation depending on the device.

Example pipeline (assuming a PNG with an alpha channel as input)

 gst-launch-1.0 -v filesrc location=test.png ! pngdec ! imagefreeze num-buffers=1000 ! videoconvert ! vtenc_h265a ! qtmux ! filesink location=out.mov

Encode 1000 frames of a PNG image with an alpha channel and save it as an MOV file.
