In new version with libcamera-still, that is, with the latest Raspberry Pi OS Bullseye installation, have you done the current test? Is it compatible? Thank you

We tried to capture from the Blackmagic Pocket Cinema Camera 6K, which supposedly has 1080p output in 10-bit. It only gave us a magenta tinted image. We tested the module with another 8bit input, which looks fine. Any idea how to get a correct image from the Blackmagic cam?

Hello, I'd like to try using this to capture 720p gameplay footage, but not all games run at 60fps, most run 30fps. Would I still be able to capture 720p @30fps with this module?

Hi,

The datasheet for Toshiba TC358743XBG states that audio can also be passed over MIPI CSI interface. Why doesn't C779 support audio?

I am seeing the error opening the interface. Any clue whether the raspivid command is still applicable with this interface? I am seeing the /dev/video0 and the kernel logs show that "tc358743 10-000f: tc358743 found @ 0x1e (i2c-22-mux (chan_id 1))"

Hi，Please try to use the EDID method to test it."Use gstreamer to call camera and audio" ; and please check whether the cable is plugged in properly before.

I did the edid load. I have a windows 10 laptop driving the HDMI-in to the module. After the EDID, the laptop sees the 2nd display. But no improvement using the raspivid.

Also tried the gst-launch with error openning audio device, and the foo.mkv is 0 bytes.

Because C779 does not support audio, please remove the audio part when you test the EDID method. （The part after mkv should be removed）.

In the features you state "HDMI Input: 720p50\720p60\1080i50\1080p25"

I am trying to make the board work with a raspberry pi with a 1080i50 (interlaced) input. raspivid -t 0 shows only a cropped area of the input. I asked the question previously and the reply from Lisa was "Hi，1080p50fps input: need to specify the encoding format； Please refer to the method called with gst" I am not trying to use 1080p50fps (progressive) but 1080i50 (interlaced). I don't understand how the encoding format is relevant when the board does not seem to decode interlace video.

Thanks for the help.

Hi :-)! I have Rpi4 with 4GB RAM. module is OK working for my purpose. next step I need to read the aux metadata from my camera... I would like to read the HDMI trigger function (REC/STBY) of the camera... It is supposed to be some flag with video signal. Do you know something about this??

Hi

What is the recommended way to mount the card to a raspberry pi 3B, in my case. Does it need a fan, if it gets hot? What is the average working temperature for the card? How high needs it be between the floor inside a case? For example 5 mm or what, 5 mm ontop?

Hi，If you want to DIY a case, please consider its size. But because each user's operating environment and Raspberry Pi load are different, we can't provide more other data.

Hi, I have a GoPro Hero 5 like the one in the demo video. I have the camera interface enable on my Raspberry Pi 4 and video0 is in /dev. And I did all the driver config I tried to run the script in FAQ - A2. It's giving me error saying "camera is not enable. try running 'sudo raspi-config'". Also, my GoPro has the output when I plug it into a monitor, but when I plug it into this module, it's not going into the HDMI output mode. I tried 1080p 24, 1080p 25, 720p 24. None of them work. Please send help

Tests with:

Sony NEX5N image output success but scrambled. Possible issue with camera only outputting 60hz?

Video capture clips also success, also scrambled.

Can you send the raspberry pi output to the camera? I tried this and am getting errors even though video 0 is showing up. I am using a raspberry pi 4 with two hdmi outputs so I am sending one back into the camera. I know this sounds wierd but I have a reason to do this. I was just wondering if anyone else has tried it and got it to work.

Dear Anonymous #6 - I tried something similar, connecting the HDMI output from a Pi 2 to the HDMI2CSI board. It didn't work. It appears that the Pi 2 insisted on 60fcs. I don't know if the Pi 4 is smarter, or if there's a way to tell it to use 25fcs for that output.
