7539a01bb0 avcodec/videotoolboxenc: Avoid copying data, allow user-supplied buffers
Here the packet size is known before allocating the packet because
the encoder provides said information (and works with internal buffers
itself), so one use this information to avoid the implicit use of another
intermediate buffer for the packet data; and by switching to
ff_get_encode_buffer() one can also allow user-supplied buffers.

41ef57fdb2 lavfi/dnn_classify: add filter dnn_classify for classification based on detection bounding boxes
classification is done on every detection bounding box in frame's side data,
which are the results of object detection (filter dnn_detect).

Please refer to commit log of dnn_detect for the material for detection,
and see below for classification.

- download material for classifcation:
wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/models/openvino/2021.1/emotions-recognition-retail-0003.bin
wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/models/openvino/2021.1/emotions-recognition-retail-0003.xml
wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/models/openvino/2021.1/emotions-recognition-retail-0003.label

- run command as:
./ffmpeg -i cici.jpg -vf dnn_detect=dnn_backend=openvino:model=face-detection-adas-0001.xml:input=data:output=detection_out:confidence=0.6:labels=face-detection-adas-0001.label,dnn_classify=dnn_backend=openvino:model=emotions-recognition-retail-0003.xml:input=data:output=prob_emotion:confidence=0.3:labels=emotions-recognition-retail-0003.label:target=face,showinfo -f null -

We'll see the detect&classify result as below:
[Parsed_showinfo_2 @ 0x55b7d25e77c0]   side data - detection bounding boxes:
[Parsed_showinfo_2 @ 0x55b7d25e77c0] source: face-detection-adas-0001.xml, emotions-recognition-retail-0003.xml

a3b74651a0 lavfi/dnn: refine dnn interface to add DNNExecBaseParams
Different function type of model requires different parameters, for
example, object detection detects lots of objects (cat/dog/...) in
the frame, and classifcation needs to know which object (cat or dog)
it is going to classify.

The current interface needs to add a new function with more parameters
to support new requirement, with this change, we can just add a new
struct (for example DNNExecClassifyParams) based on DNNExecBaseParams,
and so we can continue to use the current interface execute_model just
with params changed.

03008c2811 avcodec/speedhqenc: Hardcode table to save space
The SpeedHQ encoder currently reverses the entries of two small tables
and stores them in other tables. These other tables have a size of 48
bytes, yet the code for their initialization takes 135 bytes (GCC 9.3,
x64, O3 albeit in an av_cold function). So remove the runtime
initialization and hardcode the tables.

b05631f7b9 avcodec/speedhq, speedhqenc: Make codecs init-threadsafe
The SpeedHQ decoder uses and initializes a RLTable's VLC, yet it also
initializes other parts of the RLTable that it does not use. This has
downsides besides being wasteful: Because the SpeedHQ encoder also
initializes these additional fields, there is a potential for data races
(and therefore undefined behaviour). In fact, removing the superfluous
initializations from the decoder automatically makes both the decoder
and the encoder init-threadsafe. This commit does so.
