Module for taking screenshots from video - nginx-video-thumbextractor-module

Get screenshots from video via NGINX using ImageMagick and ffmpeg

More recently, a new module appeared nginx-video-thumbextractor-module
I wanted to publish as a link, but apparently there are no more topic links. and how the translation is no longer suitable for adding gag.
In any case, I think it's worth sharing this wonderful module with the Khabrovchan.
The status indicates that he is ready for production, which is very pleasing.

Dependencies:

• avformat - usually distributed with FFmpeg (but I had to install libavformat-dev on Ubuntu)
• avcodec - usually distributed with ffmpeg
• swscale - usually distributed with FFmpeg (but I had to install libswscale-dev on Ubuntu)
• jpeg - libjpeg
• MagickWand - usually distributed with ImageMagick

Add module when configuring / compiling ::

./configure --add-module=../nginx-video-thumbextractor-module --with-cc-opt='-I /usr/include/ImageMagick'

Recommendation:

By default, ImageMagick uses OpenMP to stream images.
The author recommends configuring / compiling ImageMagick with the option “-disable-openmp", since it is not a good idea to use streaming processing inside workflows.

Configuration:

location ~ /thumbs(.*) {
        video_thumbextractor;
        video_thumbextractor_video_filename    $1;
        video_thumbextractor_video_second      $arg_second;
        video_thumbextractor_image_width       $arg_width;
        video_thumbextractor_image_height      $arg_height;
    }

Examples of using the above configuration:

# we get a picture from the 10th second of the original size.
localhost / thumbs / video.mp4? second = 10

# we get a picture from the 20th second and a height of 50px and a length observing the proportions of the video.
localhost / thumbs / video.mp4? second = 10 & height = 50

# we get a picture from the 30th second with a height of 50px and a forked 100px, the picture will be cropped in accordance with the proportion of the video.
localhost / thumbs / video.mp4? second = 20 & height = 50 & width = 100

We take it, look at the directives on the module page .

I think this is a great solution for those who publish HTML videos to add poster:

And also when commenting, refer to some time and get a picture like on Youtube a link for a certain time.
