I have used ARVE player to stream videos from my website. Everything is fine but onload video is mute. I have tried all possible parameters but not able to fix this.
ARVE mutes HTML5 video on purpose because otherwise most browsers will NOT play them automatically. This is because browser vendors consider it to intrusive and will block all autoplay with sound. So the only option you have nowadays is to have muted autoplay.
