UV4L supports the TC358743 chip now:

I can't seem to get this to work with a B101 and a Pi3. I keep getting "Remote I/O Error". I have tried many different changes of the raspicam config file (but, most importantly setting -tc358743:yes). I have ensured that both the Camera and I2C are enabled. I am not sure what else to try.

Is the uv4l-raspicam-extras package installed as well? It's required. Furthermore, it's exactly "tc358743 = yes" in the config file or "--tc358743=yes" from command line (I suggest modifying the config file).

Yes, uv4l-raspicam-extras is installed. I have tried both adding tc358743=yes to the config file as well as utilizing the command line argument. I have also been testing the kernel driver being developed by 6by9, and it worked with that, so I know it is not the device. The second I installed uv4l, it stopped working with the 'Remote I/O error'. I have also tried with a clean install of Jessie, with no success.

I installed uv4l, it stopped working with the 'Remote I/O error'. I have also tried with a clean install of Jessie, with no success.

There was a problem with the new debian packages. The following should fix everything:

Code: Select all

sudo apt-get update
sudo apt-get install uv4l-tc358743-extras

double check "tc358743=yes" is set in /etc/uv4l/uv4l-raspicam.conf . Reboot. Retry.

It works!

Im trying to use this but not working for me.

Im sure that the auvidea board its working as i can see it with raspivid.

I follow the instructions on https://www.linux-projects.org/uv4l/installation/ and i checked that tc358743=yes its in raspicam.conf.

I did

Code: Select all

dd if=/dev/video0 of=snapshot.jpeg bs=11M count=1

and always get a black 1920x1080 screen...

¿What im doing wrong?

black? You might need to skip the first frames? Check if you get any video from the streaming server web page in the first place.

I'm also getting the "Remote I/O Error" with the tc358743 (B101):

I'm using Raspian stretch 2017-11-29 and uv4l is reporting v1.9.60. When not using uv4l (just raspivid) I'm able to get a 720p feed from the B101.
