I was wrong - it does really work! Bewertet mit 4 von 5 Sternen

The instructions for Media Sniffer are unclear because English is not the developers first language. You are required to right click on a link to the page with the video, or the video window and the right click context menu should show you something like this:

8MB-video/mp4-358871397.mp4

If you left click on this entry the URL to the video will be copied to the clipboard, and it will be like this:

https://pdlvimeocdn-a.akamaihd.net/02440/181/358871397.mp4?token2=1434571128_edc078e269c5695f1bcf9c71ec637341&aksessionid=8f9e3caf27e12d41&aktimeoffset=0

You can then paste the URL into a media player that accepts URL sources, such as Media Player Classic Home Cinema, and then the video will play in the media player with the decoder of your choice, and you can enjoy effective hardware acceleration and no more Flashplayer crashing. This is a lot easier to use than trying to detect the video URL with a network sniffer like Wireshark.

There is a program that enables you to perform the same function with Youtube videos called SVPTube, so Media Sniffer's value is to extend this capability for other Video sites.

I have tried Media Sniffer with live streams like ABC News LIVE and Euronews LIVE, but it does not work with these types of sources.

Tested with Pale Moon browser and Mozilla Firefox.

sorry.
However, this is that it can not be helped.

Live broadcast of the video is not available.
This is no exception other Firefox add-on.

This kind of video can be recorded with software called "Livestreamer"

Button is not, it will be displayed on the page area context menu.

Хорошое расширение! Раньше я пользовался FlashGot Mass Downloader, и программой URLSnooper

Perhaps you could add a list of sites you know it works on? Does it work on Vimeo, for example?

I've posted a site that worked.
However, this is only a small part
