Youtube Video Preview Image Generator
Currently, to embed a video such as youtube video on a webpage, you need to include the iframe into the html. This is a problem in markdown parsers as iframes are not allowed.
Stack Overflow has a nice solution around it. Instead of inserting the iframe, insert a video preview image to indicate to user it is a video. The image will however be a link to the youtube site instead of embedded in the page. It is a nice hack.
However, to make the preview image look like a video, you need to capture a screen shot of the video. There should be an easier alternative. After not having much luck finding such tool, I decide to make one.
Requirements
cv2, PIL, numpy
Usage
gen_youtube_preview.py <image> [image-out-width=720]
-OR-
gen_youtube_preview.py <video> <frame #> [image-out-width=720]
Eg.
gen_youtube_preview.py path/to/video.mp4 1
or for generic (non-youtube) play triangle icon:
gen_preview.py <image> [image-out-width=720]
-OR-
gen_preview.py <video> <frame #> [image-out-width=720]
Eg.
gen_preview.py path/to/video.mp4 1
This will generate a video preview image and also print out the markdown linking syntax.

All video previews in my github READMEs are generated using this tool.
