Hi,
ah ok now your link works.

So as I thought already it used dynamic playpath.
Code:
-y "19855?MTQxNjU4NDMwMzswZGIyMzc3YzE4MjgzNzkxOGI4N2Y0YTc2MzVhM2ZkNQ=="
-y "19855?MTQxNjU4OTg4MTszM2YwNjNmMDM2MmE5MjdlMWJkZWJlZWY4MmI4MTMwYQ=="
Here you need to refresh the site to get the new hash you can use then for a while.If you are looking for a permanently solution to watch the channel then you could write maybe a php script or something else (if you can etc) what does request the playpath before execute the actually entire rtmp datas with your VLC player.On the other hand you need to get the actually hash manually (no good solution I know).
