Low framerate and choppy videos

[mathdufort]

Hi balenaDash team,

Thank you for this great project. I'm trying to setup 2 displays in my university to display content for the IT department : web pages, announcements, newsfeeds, videos, etc. I find that I'm getting really choppy videos on youtube, twitch, etc. As suggested in a tutorial, I cranked the GPU memory to 296Mb but I'm still getting poor video performance. Should the videos be fullspeed or am I doing somethign wrong?

Thank you for your help and for this project!

@mathdufort what device are you using and what's your display resolution?

Hi, I'm using a raspberry pi 3 and displaying at 1920x1080 on a lcd screen hooked up via HMDI.

@mathdufort A board or B board?

It would help if the videos were transcoded to h.264 to take advantage of the onboard decoding chip. I've used https://github.com/Screenly/screenly-ose which can take advantage of this and will transcode youtube videos to the local file system then play them using the h.264 on the pi.

I've also noticed that on a Pi3, with 128-192mb of allocated GPU memory, any video played on a website or YT just crawls. Curiously, the digital signage company Yodeck has an image that allows rendering a webpage and that was streaming 4k@60 flawlessly on the same Pi3, so the hardware is definitely capable.
