Poor data transfer rates on the Gemini
« on: April 05, 2019, 01:27:41 pm »
I've recently been trying out data streaming on my Gemini, and an odd factor has emerged. As background, the data is being sourced from a Drobo5 NAS unit, through ethernet cable to a Netgear router, and from thence, via wifi to the Gemini. I also have a Nokia 8 mobile phone doing the same thing, in the same way. Both the Gemini and the Nokia 8 have the same range of software doing the streaming and display. Both using the 5g for wifi In fact, the only difference between the two is that the Nokia is on version 9 Android, whilst the Gemini is still on version 7.1.1.
Accessing the same .mkv file on both, using ES File Explore Pro feeding into BSPlayer, on the Nokia 8, playback is perfect, without a hitch. On the Gemini, however, playback is continually broken up with seldom more than a few seconds of continuous streaming, both in sound and vision, and is totally unwatchable.
Does anyone have a comment, and hopefully a reason and a solution to this problem?

I realise that I could simply copy, or FTP the file to the device, but streaming is so much better, and faster, and does not eat up storage space. Even in this there is a problem. Most video files are large, and in FTP transfer, the time taken is commensurately long. many times the machine will go to sleep during transfer, and the transfer stops. Any measures to interrupt the sleep mode serve only to abort the transfer. I have, recently, bought a Bluetooth mouse, which might introduce a sleep cancelling input without aborting the transfer, which I have yet to use for that purpose.

I tried streaming a few 1080 movies in mp4 format from my NAS to my Gemini over 2.5g Wifi and it streamed fine. Maybe it's not the data transfer rate that is the issue? I mean a 1080 movie only needs about 8mbps I think. I know the Gemini can stream data faster than that. What quality is the video? Is it 1080 or 4k? It could also depend what format the media is in. Maybe the Gemini is having trouble decoding it on the fly. The CPU in your Nokia might be a bit better and therefor can decode it faster?

Is the Gemini powered via its power supply while you're watching the streams or doing the FTP transfers, or just powered by its battery? I have seen some huge speed differences when doing FTP transfers from/to my Gemini, transfer rates are much higher if the charger is plugged in, I suspect this is because of the power saving which limits the network speed in order to make the battery to last longer. Also, when doing the transfers I always keep the lid open, that is enough to keep the download/upload going.

It was the same file in both cases, transmitted through the same interfaces, in exactly the same way. The Nokia8 phone worked and the Gemini did not. Varti might have the answer. I'll have to give it a try, later, with the Gemini on and off charge

I ran the whole thing again, tonight. The same video file, the same transmission method, the same video display, and this time it worked perfectly on both Nokia8 and the Gemini. I love computer systems, they're so illogical!!!
