Hi,

apologies if this has been covered but audio and no aren't good search terms.

I have a video playing over hls but no audio. Where do I start looking for issues that could be causing this?

thanks

Make sure your audio codec is AAC. That's the only format supported for HLS.

From what I've been told (I don't have control over the server side) the audio streams are H.264/stereo AAC conforming to the HLS specs. They do work for streaming to iOS devices and browser quicktime players.

Anything there you see that would preclude Roku support? Other settings etc in my code I could be missing?

iOS devices support MP3 as a audio stream in HLS, while the Roku does not. I don't know if MP3 is technically to spec, but it's possible that could be the issue. If the video is taking an unusually long time to buffer, there's a good chance that's the case. I'd suggest pulling down one of the TS files from the stream and analyzing it with MediaInfo.

Thanks, you were indeed correct. That's what I get for believing rather than verifying 🙂

Appreciate the support.

We'd like to add support for MP3 audio in HLS.... If you have a publicly accessible stream that we could access, that would help our testing effort. You can PM me the link if you don't want to share publicly on this forum.

Thanks,

Kevin

We are about to release into BETA the DLNA PROXY making the ROKU's have access to all sort of things. In any case, enable MP3 in audio would be a huge win from a lot points. (processing, compatability, etc).

I will place some files on our CDN and PM you the links for testing.
