VideoEncoder.allocateOutputFrame

gst.types.FlowReturn allocateOutputFrame(gstvideo.video_codec_frame.VideoCodecFrame frame, size_t size)

Helper function that allocates a buffer to hold an encoded video frame for encoder's current #GstVideoCodecState. Subclass should already have configured video state and set src pad caps.

The buffer allocated here is owned by the frame and you should only keep references to the frame, not the buffer.

Parameters

`frame`	a #GstVideoCodecFrame
`size`	size of the buffer

Returns

[gst.types.FlowReturn.Ok] if an output buffer could be allocated
