I also had this for a bit, and I found that it was specific to a few MP4's that I got. I haven't had that problem since though, so it's hard to tell if it was VideoCast or the MP4's that I was streaming....
Hope this helps.
I want to compliment the team for doing such a great job, however....I don't have a place to post praise about VideoCast....
This topic is to petition for a channel to promote praise for the VideoCast crew!
The sarcasm is perfect. There are little easter eggs like "Postponing Half-Life 3" when attempting to stream a video. The adverts for recent movies is brilliant. I've already paid for a subscription, so you have my money. Where can I go to praise the team!?
Son of a....
Literally after I posted this. I started playing it from my computer, sat on my couch, looked on my phone, and the controls showed up and is working fine. VideoStream, stop messing with me! :-)
When I open the VideoStream app from my phone, it flashes the chromecast connect button then disappears upon launch. I click a video, and it keeps searching for my chromecast, but can never find it.
I have VideoCast open on my Windows 10 desktop. I'm able to get to chromecast from their and play the video, but it doesn't let me do any controls from the app.
I restarted chromecast, my phone, and my computer....no change. :-(
