Hi all, before I set out the issue - I ACCEPT that sat boxes are designed for satellite TV; however, we are acutely aware of the existence of many a plugin / script / function even images themselves, dedicated to watching live TV stream from a server using MPEG-TS . So , ....

 

I have a supplier of live TV. They have an android app and it works flawlessly on my phone and on an android TV box. Never any issues. 

 

However,

 

When I configure my OpenPli 6.2RC 19/4/2018 build on my VU+ Duo box, using suls' excellent E2M3U2BOUQUET plugin, and watch TV streams, they freeze or glitch, The period at which they do this is random, and the freeze time is random but no more than about 2 seconds on OpenPLi. I did try OpenVIX, VTI, BH, OpenATV, OpenHD. All images displayed variances in terms of number of freezes and duration of freeze, but by the far the "best" was OpenPLi. Hardly surprising as quite a few images use OpenPLi source. I also noted that changing the channel at freeze, correctly played the new channel.

 

So, I was wondering what this freezing is due to :

 

1. Supplier: NO! The TV works flawlessly all day on two concurrent devices (mobile phone and a cheap ebay android TV box). No freezes, glitches. Cannot be the supplier. 

 

2. Network (WAN, LAN, Router): NO! because I have no problems whatsoever watching TV four hours concurrently on the android phone and android TV box.

 

3. CPU. NO! because the CPU is around 2% utilised when watching TV

 

4. RAM. NO! because there is plenty of RAM free and I have also tried with Swap file on and off.

 

5. Network adapter on the VU+ Duo. POSSIBLY? I dont know enough about how these work at the lower layers, but I guess the card was never intended to process video intensive packet data? The box used Broadcomm's BCM7335 SoC my phone (Honor 7x) uses the HiSilicon Kirin 659 octa-core. Far superior. Not sure what the android TV box (cost £40) uses (cheap eBay) but unlikely to be as good as the Honor 7X.

 

6. E2M3UPLUGIN : NO! Ive tried all the combinations of IPTV/DVB/Service ID types. A search of the net for "freeze" and "IPTV" and "enigma" reveals this is a common problem even when not using the E2M3U2BOUQUET plugin.

 

7. Enigma2 codebase.: POSSIBLY: The fact that different images gave different results is interesting. I also read on the net that someone has provided a fix for InfoBar(something). I also tried the serviceapp plugin and this did improve things greatly. So I'm leaning toward an enigma2 code issue - well not "issue" but an improvement than can be applied.

 

Does anyone know what or how we can improve this in OpenPLi?

Most (software based) media players use a high level of buffering, which allows them to mitigate any hickups in the delivery of data.

 

An STB however is designed for realtime data, and although the software can do a little bit of buffering, it isn't really enough to deal with hickups (jitter) in the stream. This is the main reason behind the "an STB is not a media player" statement. it can only be mitigated by introducing a software based media player that can deal with this, which is quite an undertaking. Not impossible, but it needs people with skills, time, and the will to make it. 

 

As this is highly related to illegal activities (IPTV providers, when it comes to TV channels, are never legal), the team isn't really interested in it. Get a subscription instead.


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

Due to my bad health, I will not be very active at times and may be slow to respond. I will not read the forum or PM on a regular basis.

Many answers to your question can be found in our new and improved wiki.
