Re: 4k Video / Audio Not Synced

Adam, your HLS stream contains audio as a separate stream or is it embedded in video TS? Also what manifest version are you using?

Re: SceneGraph Video - no audio with this m3u8 manifest

Hi Rob,

Unfortunately the manifest is not publicly accessible now, but I can set it up for you if you can answer this question first: is Roku supposed to support non-interleaved audio (separate audio tracks)? The manifest is formatted according to HLSv4

Thanks

Re: SwitchingStrategy - has anyone seen Roku switch streams?

Hi, I have tried all that. I was logging all play chunks to console for hours and hours, reordered streams, turned on large downloads on other devices on the network, but I never seen roku switch. Thus I am asking here if anyone else can test and confirm.

Re: SwitchingStrategy - has anyone seen Roku switch streams?

Hi, here is the code with a single manifest ( contains 6 streams): newContent = CreateObject("roSGNode", "ContentNode") newContent.url= "http://vevoplaylist-live.hls.adaptive.level3.net/vevo/ch1/appleman.m3u8" newContent.streamFormat = "hls" newContent.maxBand...

Re: SceneGraph Video - no audio with this m3u8 manifest

Hi Joel, Are you sure about this? m3u spec states that "EXT-X-MEDIA:TYPE=AUDIO" may be part of video TS or a separate stream ( to support multiple languages/audio qualities ). If the "URI=" field is left blank, it implies that audio is within video TS, if URI is set, then audio i...

Re: Scene Graph - Video component How to control stream qual

Hi Joel, as I replied in the other thread - it does not really matter, stream switching does not work and it is impossible to control quality. I used "Streams" variable as it provides (seems to provide) more control and this technique worked in roVideo Player. Here is a single maifest HLS ...

SceneGraph Video - no audio with this m3u8 manifest

Hi Everyone, Can someone take a look at this maifest file and let me know if you have any ideas why audio would not play. I am using SceneGraph Video node, and when trying to play this HLS manifest, there is no audio ( audio is a separate stream here). If audio is enbedded in video TS, everything wo...

Re: SwitchingStrategy - has anyone seen Roku switch streams?

According to the docs it is not the case, this is a legit way to declare multiple bitrates and stream-switching is supported. Anyways, this is just an example, I have posted a link to the manifest (containing individual streams) as well, you can just remove Streams variable and add "content&quo...

Re: Scene Graph - Video component How to control stream qual

Hi Joel, I can confirm min/max bitrate variables do not work, also I have mentioned in another thread that bitrate switching might not work either. Here is code snippet again that demonstrates it: newContent = CreateObject("roSGNode", "ContentNode") newContent.streams=[{ url : &q...

Re: SwitchingStrategy - has anyone seen Roku switch streams?

Hi Joel, Couple of questions for you: 1. When you see bitrate switching, do you see a seamless switch or video->buffering->other quality video? 2. Do you see bitrate switching on video player implemented by SceneGraph Video component or roVideoPlayer? ( I am working with SceneGraph video component) ...

SwitchingStrategy - has anyone seen Roku switch streams?

Hi Everyone, Has anyone ever seen Roku switch HLS video stream seamlessly ( while playing video ) from higher<-> lower bitrates. So far I have never seen this happen. I did notice Roku switching streams on re-buffer or choosing streams when playback starts, but I have never ever seen a "full-ad...
