Hello,

 

There seems to be a problem with the audio of IP streams of the NPO on the Mutant HD51 4K Openpli 8.2. Video does work flawlessly but the audio doesn't work. Sometimes you hear a little piece of the audio. It seems like an audio buffer over- or underrun. Almost all audio of other ip streams are decoded correctly. I hope that there is a solution.

 

Thanks,

 

Roy

What "IP stream"?


Currently in use: VU+ Duo 4K (2xFBC S2), VU+ Solo 4K (1xFBC S2), SAB AlphaTriple HD (S2+T2), (Octagon SF8008 (S2+T2), Zgemma H9.2H (S2+T2)

What "IP stream"?

IP TV streams in the Hanssat settings list, bouquet "Stream NL nationaal (NL)". And there NPO 1 / 2 / 3 HD.

The XSarius Revo 4K, which has the same CPU, but has 2GB instead of 1 GB RAM, doesn't have this audio problem. Hopefully it is a compile setting that can be fixed.

Could also be an audio codec used that isn't licenced by Mutant.

 

Is that the stream in the "Stream NL nationaal (NL)" bouquet, that is marked "++NPO - werkt niet in iedere ontvanger!++" ?

 

According to VLC it has A52/AC3 audio, which should not be a problem for the HD51, if you have an AC3 capable audio system (or TV), of if you have AC3 downmix active.

1. notes on the channel list: specials@detransponder.nl (as mentioned in the list)

2. works here in VLC and Mutant HD51 (with OpenPLi 7.3 tested). Here = NL. maybe geographic protection?

 

King regards, 'maker' Hans.

Yes, that stream. But video is working fine.

 

Downmix or passthrough don't make a difference. I do have a AC3 capable audio system and TV. There is no problem with the AC3 audio when receiving NPO 1 HD by satellite.

I don't own a HD51, so I can't do any debugging. That stream works fine on the hardware I have here...

 

@hro,

 

You can check, you have a HD51?

NPO 1, 2 and 3 tested in Mutant HD51. Video OK, audio also OK but a little bit softer than NPO 1 via satellite.
