41.25 fps from sensor sc223a (sc5239s) #1324

RoboSchmied · 2024-02-23T21:06:17Z

You can get 41.24 fps on gk7205v210 with sensor sc5239s (which openipc labels sc223a), not only 30 fps.

Set fps: 45 in /etc/majestic.yaml and Isp_FrameRate=45 in /etc/sensors/sc223a_i2c_1080p.ini.
majestic output:

Majestic says it can Not support Fps: 45, but it is running faster than only with fps: 30 settings.

~~So should this be the new default for sc223a, even if the value you set (45 fps) is not exactly what you will get from sensor (41.24 fps) ?~~

The video looks more fluently. The frames are unique. No double frames are produced.

~~Can someone owning a sc223a please confirm the frame rate after changing the 2 lines?~~
Thank you.

The sensor's physic limit is 30fps, I doubt that you really got 41.24 fps

RoboSchmied · 2024-02-28T13:35:35Z

Thank you for the info.
Actually I bought a sensor advertised as sc5239s (4MP) which OpenIPC recognizes as sc223a (2MP). And with the driver of sensor sc223a it can bring 41.24 fps.

OK, so I think the sensor distinction has to be corrected before changing any values for the wrong sensor.

themactep · 2024-02-28T13:45:43Z

Do you have a datasheet on your sensor? Read its hardware ID to confirm the model.

themactep · 2024-02-28T13:49:19Z

SC5239s would be a 5MP sensor, not 4MP. First digit denotes the resolution. If you were sold it as a 4MP, that should raise question if it is a legitimate hardware and if it is a 2MP SC223a instead.

RoboSchmied · 2024-02-28T13:56:56Z

If you were sold it as a 4MP, that should raise question if it is a legitimate hardware and if it is a 2MP SC223a instead

I bought the sensor here: aliexpress.
It is advertised as 4MP. The stock firmware offers the 4MP mode and it brings 4MP.

It is definitely not only 2 MP.

Very reassuring. You know what? I have a bridge to sell you.

Sorry, I would not doubt your expertise.

How much? ;)

Thank you. I was unaware of the sensor labeling.

Do you have a datasheet on your sensor?

No.

Read its hardware ID to confirm the model.

Ok, I will try now.

RoboSchmied · 2024-02-28T15:06:19Z

Read its hardware ID to confirm the model.

How do I get the hardware ID?

Now you need values from registers 0x3107 and 0x3108 at address 0x30. These are the most common with Smartsens sensors.

ipctool is kinda stupid and does not include the last region in the sequence. Use 0x3107 0x3109 range.

Alas, you got tricked by the seller.

RoboSchmied · 2024-02-28T16:48:13Z

Alas, you got tricked by the seller.

Maybe, but:
There are 2 main arguments that speak against the it is sensor sc223a - theory:

This system (with stock fw) can give a 4MP stream(2560x1440) that looks very sharp (no double pixel).
The sensor can do 41,24 fps with sc223a driver (which is said to be impossible for sc223a).

@themactep
Why is it important to know if it is the sc223a or not:

I changed settings (fps) in the repo for sc223a driver because it worked for my sensor. If I do not have the real sc223a, my merged repo changes may break compatibility for the real sc223a sensor in OpenIPC. This is what I want to avoid and which I (maybe) have to undo after clarification.

themactep · 2024-02-28T21:06:39Z

You have the device ID. I don't know what alternative evidence you are looking for, but I usually try to not getting involved in religious debates and debates with whitneses of SC5239S. That is a pink unicorn sensor even the manufacturer is not aware of. Google the name, you will get all kind of grifters advertizing it with parameters from 3mp to 5mp and mysteriously shapeshifting sizes.

It is the new black to upscale resolution from a shitty 2mp sensor to 2k output, or whatever the soc can handle. E.g. Cinnado D1 2K camera is equipped with SC2336 sensor. Same for dozens of other cameras on the market. Beacause marketing, and people are ~~stupid~~ gullible

The fps you get is from isp, not the sensor.

RoboSchmied · 2024-02-29T02:42:53Z

The fps you get is from isp, not the sensor.

Here you can see a capture of the stream clearly showing 41 unique frames per second with high-resolution-timer in vid, confirmed by @widgetii.

Nothing religious, pure data. ;)

jimsmt · 2024-02-29T03:22:46Z

There's possibility that it's SC233A which is capable of 1080p@60fps

RoboSchmied · 2024-03-01T13:09:00Z

Thank you all for helping.

Here we got the proof that chip ID cb3e is not unique.
3 Sensors (in openipc) are using it.

sc223a
sc233a
sc2239p

At the moment, ipctool recognizes all 3 sensors as sc223a.

This issue will be resolved here: OpenIPC/ipctool#112
