Wrong frame size

[yshteinm]

In UVCPreview.cpp function
void UVCPreview::uvc_preview_frame_callback(uvc_frame_t *frame, void *vptr_args)
you do the check
if (UNLIKELY(
((frame->frame_format != UVC_FRAME_FORMAT_MJPEG) && (frame->actual_bytes < preview->frameBytes))
|| (frame->width != preview->frameWidth) || (frame->height != preview->frameHeight) ))

The problem that in case of "frame_format" equal UVC_FRAME_FORMAT_I420 the "actual_bytes" is not equal "frameBytes" but it is not MJPEG format so the function returns without continue getting or adding any frames below
