I have some SNPE code I'm trying to run on the CDSP. When calling:

zdl::SNPE::SNPEFactory::isRuntimeAvailable(
          zdl::DlSystem::Runtime_t::DSP)

I get the following errors:

DspTransport.createUnsignedPD unable to load unsigned PD

Any suggestions?

Thanks!

The Pipe API worked great! Thanks.

Can the hires camera output RBG instead of NV12 and can voxl-camera-server support that?

Thank you for the reply. That makes sense.

What are the available outputs of voxl-camera-server? It looks like voxl-qvio-server uses a pipe. Wondering if I have another option to qtiqmmfscrc, rtsp and udp.

Thanks you, I appreciate you taking the time to reply.

Back again...

I have my ML program running now with the qtiqmmfscrc pipeline and disabling voxl-camera-server. I'd like to run voxl-camera-server with just the tracking and stereo cameras so voxl-qvio-server will get data. I tried to remove just the hires camera from /etc/modalai/voxl-camera-server.conf but running voxl-camera-server aborts:

rb5:/$ /usr/bin/voxl-camera-server -d 0

Any advice? Thank you for your time.

I think I have the snapshot hires color working!  I was grabbing the first picture instead of the last.  The first one, the sensor must not be ready.

C11. I'm trying to use the color hires one. I noticed when using the voxl-streamer, that the tracking ones and stereo is monochrome.

So now

GST_DEBUG=3 gst-launch-1.0 -e qtiqmmfsrc camera=3 ! video/x-raw,format=NV12,width=640,height=480,framerate=2/1 ! queue  ! videoconvert ! jpegenc ! multifilesink enable-last-sample=false location="/data/misc/camera/cam0_img_%d_.jpg"

is giving me no image.

All other cameras (0,1,2,4,5) are working correctly with B/W

If I enable voxl-camera-server and voxl-streamer-hires, then I get a RTSP color stream, so the HW seems good.

Thanks for your reply. I hope to have this figured out soon.

Should be hires and tracking only. I'm trying to use the color hires one. I noticed when using the voxl-streamer, that the tracking one is probably monochrome.
An older /etc/modalai/voxl-camera-server.conf.save shows all 4 cameras, tracking, hires and stereo.

Thanks for your reply. I hope to have this figured out soon.

I've been working on another RB5 platform and am migrating to VOXL. I used a command similar to above:

GST_DEBUG=3 gst-launch-1.0 -e qtiqmmfsrc camera=0 name=tracker ! video/x-h264,format=NV12,width=640,height=480,framerate=30/1 ! queue ! h264parse ! avdec_h264 ! videoconvert ! pngenc ! multifilesink enable-last-sample=false location="/data/misc/camera/cam0_img_%d_.png"

I get images, yet they are greyscale instead of color. Any help would be great!
