Intermittent stuttering on satellite radio streams (Vu+ Uno4KSE to Kodi/VLC) #3243

Hallo zusammen,

I have a Vu+ Uno 4K SE running OpenATV 7.3 nightly 24/01/2024. It is connected to a Unicable II LNB tuned to 28.2° E for Freesat UK/Sky UK. When viewing radio channels directly on the TV connected to the box they play smoothly. When I stream a radio channel to another OpenATV Enigma2 box it streams smoothly

My problem is when I stream a radio channel over my LAN via Kodi Enigma2 PVR plugin, or via OpenWebIf/VLC, the audio stream intermittently stutters and does not always buffer smoothly.

Kodi reports the audio stream of an affected radio channel as follows: "160 kbits/s, FL, FR, ff-mp2, 16 bit, 48,000 Hz". Only radio channels are affected, all TV channels mostly stream perfectly via Kodi/VLC.

I also have an Octagon SF8008 in another room, connected to a standard LNB and running the same version of OpenATV, and it does not have this problem - radio channels stream perfectly from the Octagon. I also used to run OpenVIX 6.4 on the Vu+ Uno 4KSE and it did not have this problem, with radio channels streaming perfectly on OpenViX to any other device. Therefore, this problem seems to be specific to OpenATV 7.3 on the Vu+ Uno 4K SE.

Danke,

Paul

I can confirm this. It can be solved by increasing the buffer size on the receiving side, but still there is some problem with SAT->LAN radio streaming. TV channels are free from this issue. (The receiver is a 4-tuner Sezam Marvel. I use wired home LAN between Enigma receiver and the PC.)
