At the ECCV 2020 I came across FAIR’s latest platform for object detection Detectron2. The repository includes instructions for installing with
pip. Past experience with messing up an Anaconda installation by using
pip taught me to exclusively use
To install Detectron2 with Anaconda, just run
conda install -c conda-forge detectron2
To learn how to use Detectron2 see the documentation.
conda install -c conda-forge youtube-dl
to download and install the YouTube downloader. To cut the downloaded video you can use the command line tool ffmpeg which you can get with
conda install -c conda-forge ffmpeg
Once both are installed you can download a part of video like so:
!youtube-dl <youtube-link> -f 22 -o video.mp4 !ffmpeg -i video.mp4 -t 00:00:10 -c:v copy video-clip.mp4
This downloads the video
<youtube-link> as file
video.mp4 in the format
-f 22. The second line extracts a 10 second clip from the video which will not be re-encoded and saves it as
video-clip.mp4. For more information on how to use both of these tool see the website and ffmpeg documentation.
