Re: Streaming Data to PC at 25 FPS to custom Application

Where is firmware code and where we capture the frame. Can you please point me there. From my some experiments, It looks liked the issue is either the way frame is captured or read or the issue is with the Virtual Com Port (bandwidth or speed at which data is transmitted). I would like to perform so...

Re: Streaming Data to PC at 25 FPS to custom Application

Hi, I understand that and I was suspecting that.
But can you clarify this... When I don't actually make any change to the code and just press the Disable button to enable the preview... The preview just appears there.

Does OpenMV IDE issues the call compress_for_ide() behind the scene itself ?

Re: Streaming Data to PC at 25 FPS to custom Application

I am running this code and I am getting ~32 FPS with VGA and RGB565 The real questions is this code is running on the MCU and it does send back the snapshot frame and then print the fps. On the OpenMV IDE I have disabled the the Liv...

Re: Streaming Data to PC at 25 FPS to custom Application

Interesting... I guess if the bottle neck is SD Card (Which I believe it is), then one can gain some extra speed by packaging(keep them in memory) 2,3 or 4 frames and then try writing them once... I did encountered that problem when I was writing data to SD card at 1 Khz (Not Image data)... and I wa...

Re: Streaming Data to PC at 25 FPS to custom Application

Hi kwagyeman, Thanks for the update. What VGA rate to expect if we record to SD Card ? and then later stream out to PC... Is SD card on SPI ? Since we already bought it, semi-live would work as well. For, Instance we do some live action and record and then stream it later to PC as if it is live? Tha...

Streaming Data to PC at 25 FPS to custom Application

Hi, We have bought a couple of OpenMV boards. We have some algorithm already written in C++ and they also use OpenGL for certain things as well and they work very well using video file. Now, we want to stream at least 25FPS from OpenMV at VGA Quality to PC and then feed that live stream to out custo...
