  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • HTML5 audio and video support

  • lavfi : add filter dnn_detect for object detection

    7 février 2021, par Guo, Yejun
    lavfi : add filter dnn_detect for object detection

    Below are the example steps to do object detection :
    

    1. download and install l_openvino_toolkit_p_2021.1.110.tgz from
    
https://software.intel.com/content/www/us/en/develop/tools/openvino-toolkit/download.html
    
  or, we can get source code (tag 2021.1), build and install.
    
2. export LD_LIBRARY_PATH with openvino settings, for example :
    
.../deployment_tools/inference_engine/lib/intel64/ :.../deployment_tools/inference_engine/external/tbb/lib/
    
3. rebuild ffmpeg from source code with configure option :

    — enable-libopenvino

    — extra-cflags='-I.../deployment_tools/inference_engine/include/'

    — extra-ldflags='-L.../deployment_tools/inference_engine/lib/intel64'
    
4. download model files and test image
    
wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/models/openvino/2021.1/face-detection-adas-0001.bin
    
wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/models/openvino/2021.1/face-detection-adas-0001.xml
    
wget
    
https://github.com/guoyejun/ffmpeg_dnn/raw/main/models/openvino/2021.1/face-detection-adas-0001.label
    
wget https://github.com/guoyejun/ffmpeg_dnn/raw/main/images/cici.jpg
    
5. run ffmpeg with :
    
./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,showinfo -f null -
    

    We'll see the detect result as below :
    
[Parsed_showinfo_1 @ 0x560c21ecbe40]   side data - detection bounding boxes :
    
[Parsed_showinfo_1 @ 0x560c21ecbe40] source : face-detection-adas-0001.xml
    
[Parsed_showinfo_1 @ 0x560c21ecbe40] index : 0,  region : (1005, 813) -> (1086, 905), label : face, confidence : 10000/10000.
    
[Parsed_showinfo_1 @ 0x560c21ecbe40] index : 1,  region : (888, 839) -> (967, 926), label : face, confidence : 6917/10000.
    

    There are two faces detected with confidence 100% and 69.17%.

    libavcodec/jpeg2000dec.c : ROI marker support

    This patch adds support for decoding images
    
with a Region of Interest. Allows decoding
    
samples such as p0_03.j2k. This patch should
    
fix ticket #4681.

  • lavd/v4l2 : detect device name truncation

    lavd/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).
