ParticipantI am testing the HD1 today and cannot get video or still image capture working. I recently had an SD1 which worked fine. On the same pi I cannot seem to received video. I never get the blue LED.
I am using video1 as input. When I ran pivideo -q all it reports:
Port used for video processor is: i2c1
Video processor is ready
No active video detected
Selected video source is: auto
Traceback (most recent call last):
File “/usr/local/bin/pivideo”, line 9, in <module>

KeymasterSupport for the HD1 was added with PiVideo version 1.5 – could you please upgrade PiVideo and then try querying the status again?
You can upgrade to the latest version with:
sudo pip install –upgrade pivideoJanuary 17, 2017 at 1:08 pm #916Cameron
ParticipantIt makes sense to have to update 🙂
Here is the current output from pivideo -q all:
PiCapture HD1 is ready
No active video detected
Selected video source is: auto
Active video source is: component
Raspberry Pi camera port is not active
Frame skip is On
Video processor software version: 83C103A normal pi camera does work when plugged in and I’ve tried re-seating the ribbons. Both of the two HD1 boards have the same issue.

ParticipantAlso, I have a USB capture device that works with the same input source.

KeymasterCould you please tell me a little more about what you are trying?
– How are you connecting to the HD1? HDMI or Component?
– What is the output resolution of the source that you are trying capture?January 17, 2017 at 1:52 pm #919Cameron
ParticipantConnection: Component (video1)
Source Res: HD 1200TVLThis is the actual test camera I am using:

KeymasterThe description of the camera says that that it has a 1200 tvl NTSC output – is this correct? If so, it is not providing video in a supported resolution for the HD1. The HD1 is designed to handle progressive video sources at 480p/720p/1080p. 1200 tvl is non-standard analog format that seems to be used with analog CCTV cameras and DVRs.

ParticipantI hooked the hdmi input into another pi’s output and everything works as expected.
