Trouble using the bridge with SD-SDI #8

Open Arnaud63 opened 1 year ago

Hi everyone.

I’m using your open source jetson baseboard and the SDI-MIPI bridge in order to convert an HD-SDI video flux from cameras and treat it with a Jetson Xavier NX module. Up until now I am very satisfied with the products. However, I recently tried to use it with an SD-SDI input, but I am unable to get a valid video stream (the GStreamer command shows a green screen with interferences). Is it because the deserializer or the Crosslink FPGA are unable to process an SD-SDI input stream? Otherwise, does it has something to do with the Bitstream? It is because the 3 given ones are only compatible with an HD-SDI signal?

Also, how are the bitstreams files built? Would it be possible to access the source of the 3 provided ones?

Best regards.

hi @Arnaud63 we're working on cleaning up the code and releasing it, should be public soon.

In the mean time - what video format you try to use?

Arnaud63 commented 1 year ago

Hi @kgugala Thanks for your fast response.

The video stream I'm trying to get is in a PAL resolution.

Hi @kgugala

More precisely, the SD-SDI video stream is in a PAL 576i50Hz format

Best regards.
