Re: Raspberry Pi 4 Thread - general discussion

Hi, I know it's already been said that the video core hasn't changed (only the 3d part) but, as Rodizio asked, I am also interested in knowing if the general increase in clock speeds might mean a decrease to camera video capture latency. Also, could it mean an increase in max video capture fps for r...

Re: How to get lowest latency with PiCamera

Hi, Another group that has spent a significant amount of time working on driving down the latency for Raspberry Pi camera streaming is the EZ-Wifibroadcast project. They have created a pretty full featured (and easy to install) system to transmit video over wifi for, primarily, RC vehicle/drone firs...

Re: New 8MP Camera - Q&A thread

Hi 6by9, Thanks for the reply. I can definitely appreciate that this wouldn't be a priority for you but thanks for keeping the door open a crack. On an unrelated note (and on the other end of the spectrum) what are the chances of future low resolution modes with ultra-high frame-rates (ex. 320x240@2...

Re: New 8MP Camera - Q&A thread

Hi, I noticed, on Wikipedia, that H264 level 4.2 supposedly supports up to 1920×1080@64 and 2048×1080@60. Given that you guys have managed to demonstrate 720p120 with a suitably overclocked Pi, do you think it's within the realm of possibility to hit 1080p60 or, at least, something like 1080p45? Tha...

Re: Possible source of info for DSI screens

Here's another link that seems to connect to the same conversation: http://comments.gmane.org/gmane.comp.bo ... oot/129063

I found it by doing a Google search for "amoled dsi driver".

Possible source of info for DSI screens

I realized that I posted this in the wrong forum, so I'm cross-posting it here. Sorry if this annoys anyone. I'm not sure how useful this will be but since Apple tends to be relatively tight-lipped about the low level specs of their hardware, another source of some of the best smartphone displays is...

Possible lead on DSI display

Hi, I'm not sure how useful this will be but since Apple tends to be relatively tight-lipped about the low level specs of their hardware, another source of some of the best smartphone displays is Samsung's AMOLED line. With that in mind, I did some digging online and came across a number of pages li...

Re: What happened to the Model A?

Since the Mode A will be missing a few things (like Ethernet) does that mean that there will be a few more unused GPIO pins that will now be available?

Re: Reverse engineering GPU drivers from other devices using the BCM2835

<t>Unlike manis404, I am more interested in DSI drivers for cheap replacement smart-phone displays.<br/> <br/> With that in mind, I'm curious how possible it would be to (assuming a suitable Nokia smartphone could be found which uses this chip/GPU) rip the binary driver out of that phones OS and use...

Re: DVI / HDMI video-in

<t>As far as I know, all of the higher end smartphone displays output full 24-bit color.  For instance, the Wikipedia page for the Galaxy Nexus states that Samsung's Super AMOLED displays are 24-bit.  Since the future projects I'd like to use this converter for involve rich media content like games ...

Re: DVI / HDMI video-in

<t>Hrm, that's unfortunate. With enough ports, I wouldn't have thought the chip itself would have a problem with the data rate since it doesn't need to do anything other than transfer the data into the frame buffer.  As for the GPIO read speeds,  even the speeds I've seen most other ARM chips handle...

Re: DVI / HDMI video-in

<t>I appreciate the response, but any detail on why not?  Most of the ARM architectures I've seen seem to allow for re-allocation of pins for use as GPIO and, with enough GPIO pins, the read speeds I've seen being accomplished for other chips seem to be fast enough to handle the incoming data.<br/> ...
