PiCaptureHD1 MMAL

[Cameron]

I 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):

Support 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 pivideo

It 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: 83C103

A 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.

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

Could 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?

[Cameron]

Connection: Component (video1)
Source Res: HD 1200TVL

This is the actual test camera I am using:

I use a BNC to component video cable to connect the camera to the PI.

The 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.

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