steam in QVGA and record in VGA

[monroed11]

Hi,

Is it possible to stream and record using different resolution? I want to save a high resolution video and stream at the same time but due to wifi latency, I cannot stream on high fps(more than 10). I figured if I could stream using QVGA resolution I will achieve that framerate. Any key pointers would be appreciated.

Hi,

I don't think so as you have to tell the camera what resolution to operate in so it would need to reset the camera every frame
I also think any attempt to resize a captured image would take the esp32 so long that the frame rate would be reduced far to much

I found this link regarding down-sampling an image:

But I am having a hard time incorporating on the code you posted.

Where I now is: if streaming, use VGA resolution, if recording use HD resolution. I know its a hack but since it is not possible, this is the closest thing I got instead of down sampling.
