I would also assume it uses dedicated chip for HEVC encoding.

Syme Posted March 13, 2016 Share Posted March 13, 2016 I'm pretty sure the encoder is integrated into the main SoC. I can't imagine Samsung using a separate physical chip when the main one is already a custom SoC they made for their cameras. sidi 1 Quote Link to comment Share on other sites More sharing options...

But it is not at a quantifiable stage at the moment, What I have found out is pretty much just a key, and if the key can open the lock is not yet determined. Even with the sdk things of this nature are not 100% At any step of the way if they did something undocumented it can halt progress to a point the modification cant be done. Ive been lucky so far with things is all! But if knowing that what Im doing may not bring a firmware mod to light people still wish to donate then I can put something together. But I started this not knowing there was anyone wanting this camera modded, and I would still do this if no one wanted to tip/donate. That being said the next stages of what I am doing are copious research. There are white paper behind paywalls but my local university seems to have most of the books on file so I will be acquiring those to get a better idea of the way samsung chose to code. Personally I am also interested in the lens mount for a working adapter to other lens systems. So the control files are something I am also looking into. As well as if hevc is the best choice for encoding or if something like the redcoderaw would be more suitable which is just their modded version of mjpeg2000. dct vs wavelet is something interesting to read about.

Chant Posted March 13, 2016 Share Posted March 13, 2016 The samsung srp research is also to see if thats what they used, but it it was an onboard hevc asic there would be a lot less code for what Im finding if you go by what tends to control hardware. With luck its srp because Ive found examples of it beings used to do a full 8k6p stream with a very small srp block and the drime-v is a very different beast from the exynos. But ill just leave these excerpts here.

Marco Tecno Posted March 13, 2016 Share Posted March 13, 2016 Chant: Not sure if I understand. You mean that if nx1 has this programmable chip, it could be able to output at 240fps? Doesn't this depend also on the sensor? 3 hours ago, sidi said: Thanks, still looking for NX1 bottom connector. You mean the one for the grip?

Chant Posted March 13, 2016 Share Posted March 13, 2016 The code excerpts I posted are from the firmware. The statement about the camera being able to do 240fps is something they didnt remove. Also found a bunch of tizen watch stuff. Bad housekeeping is good news. But I have yet to find a video output path that is concise. Tons of data on the hevc and everything else, but its what pointed me to the srp and needing to do more research. There way a camera would dump data to an onboard hevc is pretty well documented. Follow the mipi csi-2 bridge a few steps to get to the encoder. but the difference is, if it was indeed just a "hard" core hevc in the drime-v it would be more self contained. Taking what I know of chip construction and "hard" core asic implementation. The more I do the more I find on how it works and what can be done.

Marco Tecno Posted March 13, 2016 Share Posted March 13, 2016 I guess you can only pass some energy (external battery) and few commands from there, like shutter. Quote Link to comment Share on other sites More sharing options...

Popular Post hirsti Posted March 13, 2016 Popular Post Share Posted March 13, 2016 Here is a quick video showing the NX1 and NX500 SD Card Hack for Focus Buttons. This program allows you to record up to 6 focal points, these are stored on the SD card and will work after a camera restart. This works for photography, especially good for storing infinity focal point to re-use when it is dark for Astro Photography. Works in video allows you to do focus pulling from one focal point to another.

Good idea, the angle could be: Samsung abandons their loyal nx1 customers, but a community tries to keep the future of the camera alive.
