Question

I Have a video here Hosted by https://kavimo.com/

https://stream.biomaze.ir/i3zqz9fhf69f/iframe

It is kind of an m3u8 but I could neither download the m3u8 file nor download the Video does anybody know how we could go around this ?

the file is MP4 (i3zqz9fhf69f-1080p.mp4 7.06 MB (7,411,920 bytes))

address after cookies is https://stream.biomaze.ir/i3zqz9fhf69f/download/1080p

however, you need a puppet to press the download icon in the frame

https://stream.biomaze.ir/i3zqz9fhf69f/iframe

that requires an emulation sequence of start by press big play button

<svg class="icon-hexagon play-big-bg" style="fill:#074EE8" viewBox="0 0 512 512"><g><path d="m219 21c25-14 49-14 74 0l148 86c24 14 37 35 37 64l0 170c0 29-13 50-37 64l-148 86c-25 14-49 14-74 0l-148-86c-25-14-37-35-37-64l0-170c0-29 12-50 37-64z"></path></g></svg>

then tab enter will trigger the mp4 download

they recently added the download button I had to make a Script to download by m3u8 i'll share it now... — X-_-FARZA_ D-_-X, Nov 03 '22 at 20:42

this Script is able to download any video hosted on stream.biomaze.ir

it Asks for an ID which for link https://stream.biomaze.ir/i3zqz9fhf69f/iframe is equal to i3zqz9fhf69f

side note: you have to install and add ffmpeg to path
