7a879cce37 libavfilter: vf_drawtext filter support draw text with detection bounding boxes in side_data
This feature can be used with dnn detection by setting vf_drawtext's option
text_source=side_data_detection_bboxes, for example:
./ffmpeg -i face.jpeg -vf dnn_detect=dnn_backend=openvino:model=face-detection-adas-0001.xml:\
input=data:output=detection_out:labels=face-detection-adas-0001.label,drawbox=box_source=
side_data_detection_bboxes,drawtext=text_source=side_data_detection_bboxes:fontcolor=green:\
fontsize=40, -y face_detect.jpeg
Please note, the default fontsize of vf_drawtext is 12, which may be too
small to be seen clearly.

981c4caed3 avcodec/pnmenc: Avoid intermediate buffer, allow user-supplied buffers
For all p*m encoders a very sharp upper bound for the size of the
output packets is available before the packet is allocated. This can
be used to avoid an intermediate buffer when encoding by using
ff_get_encode_buffer() instead of ff_alloc_packet2() (without min_size);
this also adds support for user-supplied buffers.

When the packet size is known in advance like here, one can avoid
an intermediate buffer for the packet data; also, there is no reason
to add AV_INPUT_BUFFER_MIN_SIZE to the packet size any more, as the
actually needed packet size can be easily calculated: It is three bytes
more than the raw nal size per NALU.
