Re: GPU Performance increase on RPi 4B

in my limited experience of using non-linear video editing, it was on machines much less powerful than the pi4u but that was quite some time ago...

I suspect the problem is more likely to be the quality of the software than the hardware,

Re: RPi 4 2GB - Cant set gpu mem above 600 / black screen

Hey all, Im trying to setup my pi to run videos off my server as reasonably fast as possible, having a collection of 720 to 1080p to 4k files on there. I did some research and found that more memory would help that along, as the default would stutter and lag like crazy on default. As the title says...

Sorry NO!
It was stated above, but there are no pm facilities on the board, and mods have no access to users email addresses for privacy reasons.

Hi,

Is there a Zwave USB stick which works with the Pi4 ?

Thank you.
We've done some investigation on these and they are not USB compliant. Some people have found they work ok through a hub.

Re: Raspberry Pi 4 Thread - general discussion

I like the flirc case but it does get hot when under heavy load, a fan will keep the device much cooler. But consider what heavy load is. Most people using the device as a desktop won't stress the flirc case overmuch.

Re: pi 4B not showing Video on HDMI0 if memory split set to 896MB

We've probably never tested with those sorts of number because they are totally unnecessary. 128-256 is the max you should need., and you can get away with 16 or 32 depending on use case. I doubt we will investigate why it goes wrong, simply because is so far out of what is sensible to use.

Cannot comment on why the :gpu settings say it is not accelerated, but with regard to the higher CPU, Chrome has a much more complex path for the video data to get through to display. For example there are colour conversions and entire frame copies (done at 30 frames a second, multiplied by the data...

I wish we had never mentioned reflashing the EEPROM, it's never that that causes a problem. Chances of corrupted the EEPROM are practically Zero.

4 flashes means the SD card isn't right. (or much less likely that the Pi SD card interface isn't working). Double check you are writing the images correctly.

There is no need to set it to more than about 256MB, that will be enough for all almost use cases. If you are not using the camera or H264 codec, you can set it to much lower.
