You need an ffmpeg that has been taught how to use the hardware decode
features on your SOC.
Don't know if
You are right, i changed the input format to NV12 on GuvcView and got lower
CPU usage (250%) and Temp ~75C.
I does not help much overall.

Some cameras are H.264 aware and they usually uses the UVC interface.
They usually are mounted as two /dev/videoX devices. The YUYV amd MJPEG are
on video0 and H.264 on video1. I have a couple of ELP cameras that do that.
They really good.
I have tested them OPI PC they work just fine.

It dual stream is feature of camera firmware. It is part of the Skype

Interesting, can you check if it is a feature of this camera or the new
kernel?
If you have OPI PC, can you check that?

I have this camera, and if you change the "start_video.sh" script to
something like this
you can see... the results... the CPU usage is much lower...

This is done so that the screen display app can use the the
uncompressed stream while forwarding on the h.264 stream without
decompressing it. The uncompressed stream does not need much CPU to
display.

Inspired by so many good arguments on USB uvc cameras i decided to test
one, a 720P HD used in ODROID, so you can take a look and see how good it
is for Orange Pi PC (Allwinner H3) and decide if having Encode/Decode by
HW worth the effort or we throw in the towel, it is up to you.
This is simp

Jon,
Thanks for yours always informative posts.
I think someone should come up with a HDMI ==> CSI (MIPI ) interface board

gspca is around 10 years old and it pre-dates UVC.
The 291 image chip can take higher resolution stills, but mine only
has a 720P sensor on it.
The 292 image chip has similar performance at 1080P.
I have wasted far too much time trying to get Allwinner cameras
working properly and I won't touch t
pinctrl-sun8i-a33.c (and the dts) declare only 2 interrupt banks,

However the A33 being the A23 derative it is means tha

Thanks Jon.
I have some thoughts on this proposed hardware solution:
* This camera will not be recognized as uvc usb device, unless you add it
to the device list, no big deal i think.
Your kernel is 3.3 but i think you or someone else already added it to uvc
device list. (i may be wrong),

So a long later I think I might have stumbled onto the explanation for
this in the Freescale ASOC driver (fsl_dma.c).
/**
* fsl_dma_hw_params: continue initializing the DMA links
*
* This function obtains hardware parameters about the opened stream and
* programs the DMA controller accordingly
Hi,
Thank you for your reply.
I forgot to mention thet the question is valid for A20.
The only reference i can find is EINT0 for pin PH00, unfortunately i cant
assign this value in the driver and the only clue i got so far is the use
of gpio_to_irq function
but this doesn't work or i don't know

Hello all,
I am trying to add the MPU9150 driver in to kernel 3.4.39
In the mach-sun71/core.c i have

Hi Danny,
I've got some patches to go which covers pretty much everything that
we can manage with the sun4i-codec. I'm only lacking testing of
certain bits as I don't have capable hardware(i.e. FM capture). I've
ignored the phone out part of the A20 as I couldn't find the pins.
I'll try to upload t
