Re: Slow video on 1920x1200 screen

I know it's been a long time, and quite possibly no-one is watching this topic any more, but I have now had a chance to try a few more things and wish to post details and a couple of corrections. First, thanks to KenT2 for your suggestion, and I am definitely going to have a look at PiPresents when ...

Re: Slow video on 1920x1200 screen

So, does omxplayer launched from command line have the same slow framerate issue? Or is it only with your python wrapper code? Yes, of course, that was the next thing to try. It seems to be quite happy if I let it boot, ctrl-C my player and then play the files from the command line. I don't know if...

Wouldn't have thought so - I have 64M for the GPU and have previously tried 128M with similar results.

Re: Slow video on 1920x1200 screen

I have now tested the two config.txt changes suggested. I also tested a bunch more: key: A = problem as originally described (video is jerky etc) but all files play. Holding image is often off-centre for some reason (probably related to my software) B = first video file plays correctly but thereafte...

Re: Slow video on 1920x1200 screen

Thanks for that - I'll give it a go and let you know. Unfortunately I've just used up my last spare SD card so it probably won't be today.

(I do have a bit of trouble with SD card corrpution, but that's another issue!)

Slow video on 1920x1200 screen

I have a stand-alone video player that essentially just plays all the files in a particular directory using Omxplayer. It boots to the player (written in Python) in the command line and doesn't touch the desktop. The player also plots a "holding image" on screen which is covered by the vid...

Just a bit surprised that since Eben's giving a talk and since there's the possibility of tickets to the general public this hasn't been mentioned - or at least, I haven't seen mention of it.

Hwyl!
