After flashing our PX2 to DW 1.2.400, the input format for recorder has changed.
The new format can be found at /usr/local/driveworks/tools/capture/configs/hyperion7_1/release.json
and defines 2 cameras, one per channel, second one in slave mode.

        },

Since before PX2 update I was able to record 8 cams ( 4 on port ab, 4 on port cd )
I wonder, how the rig configuration has to be changed in order to record the 8 cameras again?
Thanks for your support

Since I cannot find any documentation about, any clarification would be appreciated.

Any support on this would be very helpful. Thanks.

Dear @hermann.f ,
Could you check /usr/local/driveworks/doc/nvdwx_html/dwx_recording_devguide_basic_recording.html. You could see configuration example of adding 3 cameras (2 from a and 1 from c). Let us know the feedback
