Preview of video files

[lebouquetin]

Currently, preview-generator does not allow preview of video files.

Expected: generate an image preview of video files.

Here is a way to do so:

1. get video file duration in seconds: ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 <videofile>
2. compute the timeframe at 5% (ie duration/20)
3. extract the frame : `ffmpeg -ss -i -vframes 1 -q:v 2 <preview.jpeg>

Finally, the right way to implement video preview generation would better be based on https://github.com/kkroening/ffmpeg-python

Note : implementing support of video files in preview generator should come with mediainfo features for extracting video metadata (for json preview)

How to use it? It says that "video/mp4" is not supported.

@Alynva Can you give us more information on what you are trying to achieve? What is your setup? How are you using preview-generator? Can you provide us with a snippet of code exhibiting your issue?
You might want to open a new issue, this one is solved since 2019.
