Roku Developer Program

[daria]

Hi!

My application should be able to play a number of videos, and some of them are from YouTube. I'm getting mp4 urls from YouTube API, but Roku is only able to show streams with low quality.

That's example code (actually it is from Roku samples, I just specified another url):

    this.player.SetContentList([{
        Stream: { 
            quality: true
            url: "http://r8---sn-n3toxu-axqe.googlevideo.com/videoplayback?itag=22&mn=sn-n3toxu-axqe&cnr=14&signature=9A9E9052BF12F7CDA68C124344AFDD34B404E111.C3A0F27722821D752BB7EE7161B6B952DDD9EBAD&key=yt6&ms=au&mv=m&mt=1464891262&dur=1861.590&sver=3&lmt=1461051538955103&ip=188.242.217.203&fexp=9405824%2C9416126%2C9416891%2C9418403%2C9418777%2C9422596%2C9422842%2C9425619%2C9428398%2C9431012%2C9432025%2C9432564%2C9432684%2C9433096%2C9433380%2C9433457%2C9433946%2C9435138%2C9435398%2C9435527%2C9435697%2C9435876%2C9435944%2C9436061%2C9437066%2C9437079%2C9437158%2C9437424%2C9437553%2C9437948%2C9437955&expire=1464913144&id=o-AJMBGGWdHjXllrg-2eatT_OGvNBh4tt8raTNujubGm7s&upn=sRjfQCpMbo8&initcwndbps=3315000&source=youtube&sparams=cnr%2Cdur%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Cratebypass%2Csource%2Cupn%2Cexpire&pl=24&mm=31&ratebypass=yes&ipbits=0&mime=video%2Fmp4"
        }

        isHD: true
    }])
    this.player.Play()

YouTube API returns several urls for different formats, and for other urls playback works fine, but they have much worse quality.

Such HD urls are working fine in browsers and mobile applications (Android and iOS). Why Roku app doesn't want to play it and is it a way to fix this?

How are you using the YouTube API to get the mp4 urls?

Last time I checked that it was against their TOS to use a non-youtube player for their videos. Has that changed?

It seems that issue is not about YouTube. Found a video with same error located on other server. Video info is below. What can be wrong with it?

Currently HD videos don't play on Roku other than through the official Youtube. Something changed in their transcoder a few months back. If you try and download an mp4 directly from Roku and play it through Roku Media Player, it will also fail. The file needs to be transcoded to play. Noticed this a couple months ago when trying to use Watch Later with Plex.
