static int storeframe ( AVCodecContext avctx,

Store coded frame information in format suitable for return from encode2().

Write information from cx_frame to pkt

Returns
packet data size on success
a negative AVERROR on error

static int queue_frames ( AVCodecContext avctx,

Queue multiple output frames from the encoder, returning the front-most.

In cases where aom_codec_get_cx_data() returns more than 1 frame append the frame queue. Return the head frame if available.

Returns
Stored frame size
AVERROR(EINVAL) on output size error
AVERROR(ENOMEM) on coded frame queue data allocation error
