PIVIDEO not working

[contact]

Hello setup:
RPI3
raspbian 4.9
python 2
i2C1 connexion tested (detected board addr 40)

Hello
I follow exactly what is indicated in the manual pdf, but there is an error and PIVIDEO no work.
I always get this error message:
pi@raspberrypi:~ $ pivideo –q
Traceback (most recent call last):
File “/usr/local/bin/pivideo”, line 7, in <module>
from pivideo import main
File “/usr/local/lib/python2.7/dist-packages/pivideo.py”, line 27, in <module>
import serial
ImportError: No module named serial

It appears that your python installation is missing the serial port interface. You should be able to install it using pip:

sudo pip install pyserial

We should identify this as a prerequisite in our PiVideo package, but haven’t because it is a part of the standard raspbian distribution. I will look at this for a future release of PiVideo.

ok thank you

No there’s no this error but another:

I’m trying to see the firmware version, I have hold picapture HD (s/n 0717-00094) that work perfect in our app, with no lag, and last orderer one s/n 1617-20260 give us 4 seconds lag on our application…..

I want to put the same firmware on the new one than the old one.

Please help me.

I believe that the command you need is:

pivideo -q all -v

“query” requires a parameter, and “all” shows everything including the version.

Hello, this worked perftly, thank you, I resolved my lag issue by activating skip param.

There is possible to set video processor to start even if there is not camera connected to it?

[mwlinder]

The PiCapture board requires a valid video source before sending video data to the Raspberry Pi. This allows the PiCapture to “scan though” the various video sources and resolutions to look for a signal.

[contact]

Ok this is the standard, but I need that video processor start even if no video signal is in HDMI and I need that until video signal is detect on HDMI that picapture output an image (mir or logo). I always input 1080p 30fps in HDMI. We never use the other input.

There is possible to set scrip that make that on the video processor?

[mwlinder]

A firmware change to PiCapture would be required to generate a video signal with no input.

If you could explain a bit more about what you are trying to accomplish we may be able to help. Please feel free to email: contact@lintestsystems.com
