av_mallocz() is superfluous as get_packet_defaults() is called immediately
after it's allocated, which will initialize the entire struct to default
values.

If a copy callback is provided by the caller, the packet passed to it
was zeroed instead of initialized with default values.

Libavcodec can now handle the AV1CodecConfigurationRecord structure
as-is when passed as extradata, so the standard behavior of
read-box-into-extradata should suffice, just like with AVC and HEVC.
The SVQ1 decoder does not need mpegvideo or rl.c, but it uses stuff
from h263data.c. But since 61fe481586
h263data.c called ff_rl_init() and this of course led to build errors
when the SVQ1 decoder is enabled and mpegvideo disabled.
Fix this by moving ff_h263_init_rl_inter() to h263.c.
Fixes ticket #9224.

MSA2 optimizations are attached to MSA macros in generic_macros_msa.h.
It's difficult to do runtime check for them. Remove this part of code
can make it more robust. H264 1080p decoding: 5.13x==>5.12x.

1. Refined function get_cabac_inline_mips.
2. Optimize function get_cabac_bypass and get_cabac_bypass_sign.

The MSA optimization has been refined in commit 93218c2 and ce0a52e.
It is better than MMI version now.

It is not documented to be safe to call inflateEnd() on a z_stream
that has not been successfully initialized via inflateInit(); so
record whether it has been successfully initialized.

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.

Said RL VLC is only used by the decoder, ergo don't initialize it for
the encoder and move the whole code and the RL VLC table itself to
dvdec.c.
Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
It can and therefore we switch from a heap allocated VLC table to
a VLC initialized via the mechanism for static VLCs, but without
an actual static VLC.

It is init-threadsafe since b9c1ab8907
and except on MIPS even before that due to its use of ff_thread_once()
for static initialization.

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:
