why not put_video ???

If you want to show a video which is from the internet, you can use this code:

url = "https://interactive-examples.mdn.mozilla.net/media/cc0-videos/flower.mp4"
put_html('<video controls="controls" src="{url}"></video>'.format(url=url))

If you want to show a video from local file, one way is to use static_dir parameter of start_server to
map a local dir to the static path of your pywebio app:

import pywebio
def main():
    url = "static/video.mp4"
    pywebio.output.put_html('<video controls="controls" src="{url}"></video>'.format(url=url))

pywebio.start_server(main, static_dir='video/', port=8080)

You need put your video file video.mp4 to the video dir.

By using this way, anyone can use the link http://your-app-server:port/static/video.mp4 to access the video.

If you want the video to only be accessed by current user, you can provide video content with a base64 encoded Data URI as source:

from base64 import b64encode
content = open('video.mp4', 'rb').read()
b64content = b64encode(content).decode('ascii')
src = "data:;base64, {b64content}".format(b64content=b64content)
put_html('<video controls="controls" src="{url}"></video>'.format(url=src))

However, in the data uri way, the video can't be show until the whole file are transfered to user broswer, this may be very slow.

Since you need to consider so many things like this, I don't add the put_video() to pywebio. But I think I will add put_video() supporting to my to-do list.

Thanks again！

We really need put_video!!!
I wanted to display the yolov5 processed camera video in PyweBio, but using put_image I could only get a continuous image display that included a lot of white space transitions
