lavfi/dnn_classify : add filter dnn_classify for classification based on detection...
17 mars 2021, par Guo, Yejunlavfi/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.labelrun command as :

lavd/v4l2 : detect device name truncation
25 novembre 2021, par Anton Khirnovlavd/v4l2 : detect device name truncation
Silences the following warning with gcc 10 :
src/libavdevice/v4l2.c : In function ‘v4l2_get_device_list’ :
src/libavdevice/v4l2.c:1042:64 : warning : ‘%s’ directive output may be truncated writing up to 255 bytes into a region of size 251 [-Wformat-truncation=]
1042 | ret = snprintf(device_name, sizeof(device_name), "/dev/%s", entry->d_name) ;
| ^
src/libavdevice/v4l2.c:1042:15 : note : ‘snprintf’ output between 6 and 261 bytes into a destination of size 256
1042 | ret = snprintf(device_name, sizeof(device_name), "/dev/%s", entry->d_name) ;
| ^Previous patches intending to silence it have proposed increasing the
buffer size, but doing that correctly seems to be tricky. Failing on
truncation is simpler and just as effective (as excessively long device
names are unlikely).
