Could you tell me what web hosting plan at www.andreyknure.narod.ru is the most suitable for streaming video web site

They're all equally good. Hosting like that has a very large throughput, and you can stream video from any of them. Cheap hosting tends to bit a bit unstable, however, and I recommend investing a bit more.

Streaming media is an expensive hosting and I do not think any of those plans advertised as a specialized plan for streaming video. If you are serious about your website, you would go with a plan that is meant for streaming video (else you may find your website slowing down, or your host cutting down your resources because they are not expecting you to draw huge resources.

Plus several tools like FFMpeg, Mplayer etc may not be there. You can try a ffmpeg hosting meant for streaming video such as https://www.bizstreet.net/ffmpeg-hosting...
