cat /sys/devices/pwm-fan/rpm_measured

 

# Fan running full capacity 

echo 255 > /sys/devices/pwm-fan/target_pwm

 

# Trun off fan

echo 0 > /sys/devices/pwm-fan/target_pwm

1. For PCIe devices, try changing the device to a different PCIe slot and make sure the hardware installed correctly.
2. For Mini card devices, there are two spec m-PCIe and USB make sure the slot installed matches the Mini card requirement. You can find the Mini card spec in Mini card data sheet.
3. For USB devices, check the product specifications (USB 2.0 or USB 3.0) and update the motherboard USB controller driver.
4. If the above methods did not solve the issue, please contact our technical support team.

If an Embedded Server is required, contact us for further information.

1. Yes, most PCIe x16 slot are backward compatible with x8 x4 x1. Check your motherboard manual to find PCIe slot compatibility.
2. Possible combination:
PCIE x1 in PCIEx1, PCIEx4, PCIEx8, PCIEx16
PCIE x4 in PCIEx4, PCIEx8, PCIEx16
PCIE x8 in PCIEx8, PCIEx16
PCIE x16 in PCIEx16

Video signals vary, for example medical systems have special requirement. For such circumstances please contact our technical support team.

Make sure the input signal resolution is the same as the SDK/Capture Studio settings.

1. Make sure the cable is connected correctly.
2. Check if the driver and software versions are up to date.
3. Check the supported resolutions and make sure the input signal matches the software settings.
4. Confirm format alignment. For example, if the input signal is digital, a product that only supports analog will not display a signal.
5. If the above methods did not solve the issue, please contact our technical support team.

1. Check the resolution.
2. Make sure the input signal resolution matches the SDK/Capture Studio settings.
3. If the above methods did not solve the issue, please contact our technical support team.

Check if the video is protected by HDCP (High-Bandwidth Digital Content Protection). Unauthorized HDCP video content is not supported.

Contact us and provide your Linux and kernel versions. We will provide you with further information.

1. Verify which architecture, 32 or 64 bits, you are running.
2. Change the software settings to match the OS.

SDK does not support MP4 recording with an SD source.

Capture Studio supports Capture Record.

Our USB 3.0 products are not compatible with previous versions (such as USB 2.0).

1. When recording AVI, make sure your HDD’s RPM speed meets sustained transfer speed requirements.
2. When recording H.264, make sure your CPU can meet the performance requirements.

1. There may be conflict issues between installed driver/applications. Remove all AVerMedia driver/applications then restart the system and re-install the driver.
2. If above method did not solve the issue, please contact our technical support team.

To choose video source, enter the following:
v4l2-ctl -d /dev/video0 -i 2 (HDMI = 1, VGA = 0, S-video = 2) value depends on capture card.

To check resolution, enter the following:
 v4l2-ctl --get-fmt-video

 Other commands
 <V4L2 utils>
 replace '$' with your device index

1. To install v4l-utils, enter the following:
 # apt-get install v4l-utils (as root or with sudo)

2. To check C353 video device index, enter the following:
 # v4l2-ctl --list-devices

3. To set video input, enter the following
 # v4l2-ctl --device=/dev/video$ --set-input=<index>

4. To set output video format, enter the following:
 # v4l2-ctl --device=/dev/video$--set-fmt-video=width=<width>,height=<height>,pixelformat=MPEG

5. To set default video format, enter the following:
 # v4l2-ctl --device=/dev/video$ --set-fmt-video=width=0,height=0,pixelformat=<MPEG or YV12>

Example:
1. To downscale to 1280x720, enter the following:
 # v4l2-ctl --device=/dev/video0 --set-fmt-video=width=1280,height=720,pixelformat=MPEG

2. To reset to default resolution, enter the following:
 # v4l2-ctl --device=/dev/video0 --set-fmt-video=width=0,height=0,pixelformat=MPEG

Yes, please refer to the document for details.

No, by default AVerMedia products do not support HDMI CEC. However, if you have such a requirement, please contact us.

Due to the regulation of MPG specification, the maximum is up to 1088 resolution.

Customers can develop their own software with CL311-M2 to implement broadcasting closed captions or use the 3rd-party software (ex. VLC) for broadcasting closed captions.
