The beginning of the discussion was here:
habrahabr.ru/qa/16055/
habrahabr.ru/qa/16723/

Wait! There have been some broadcasts. Volunteers and craftsmen are very much needed to establish the most convenient way to save the video stream.

Are there any connoisseurs of flash and networking on Habré after all? Who knows how video broadcasting via flash works? Is it a TCP or UDP stream? How to competently grab it and then turn it into a video file?

We have the opportunity to apply our knowledge for important purposes - so let's do it! If we have complete video files of the entire voting process in a particular precinct, we will be able to count the number of real votes! If we find an easy way to save video streams, many people will be able to do this, which means that verification can be arranged in many areas.

A REQUEST TO SKEPTS AND MEMBERS OF THE UNITED RUSSIA PARTY: DO NOT WRITE GARBAGE MESSAGES. EVERYTHING ONLY TO THE ESSENCE!

Judging by the link from pastehtml, there will be a stream on this link 188.254.112.52/master.m3u8?cid= <Camera ID>
but in general, until there is a real stream, it is unlikely that something can be advised.

Well, yes, the concept sketched on the knee works.

Look for programs that can save flash later, nothing abstruse is needed here. For example here.

This is an RTMP stream (usually). Use for example rtmpdump or any software from here .

The links that were in that post are the streams used to receive the camera: there is a web service where the installer checks the “Camera on Wick 123 is installed”, and a special person looks at the broadcast and puts an assessment (working / not working / etc. .P). There is a probability that the same streams will be given on Sunday, but it is far from 100%.

sergehog, I'm surprised at your unwillingness to think with your head. You were previously given the most realistic option:
“Take a more powerful computer. Put on it several virtual machines with windows and installed virtualdub. On election day, on each virtual machine, open a browser with the view of the desired sections running and start recording from the active window. You set up the video with a rate of 1-3 frames per second.
Why so right?
- Reliable, because If the video broadcast is interrupted, then the video recording will not stop.
— Volumes, because there is no need to record the entire stream frame by frame, it is enough to make 1-3 frames per second.
- It will definitely work, because. it is highly likely that the streams in the camcorders will change periodically.

Does the last paragraph of the "Help" section bother anyone?

During the broadcast, each user will be shown a captcha once every ten minutes - a set of characters that must be entered in order to continue watching the video. This restriction is designed to reduce the consumption of server resources: if the viewer left the computer, leaving the broadcast on, then in ten minutes the broadcast will stop if the user does not return and enter the captcha.

Developers tools in Chrome or Firebug, see where the stream will come from and download it with wget, or get it from the browser cache.

If the links in the player go to the m3u8 file, then HTTP Live Streaming is used, it can be captured with ffmpeg.

Ha-ha, how naive. Court Verdict: "Made in California!"
It looks like they figured out what this multibillion-dollar and ... action with cameras was started for: vice-chancellor.livejournal.com/195236.html :)
