Packet losses on Windows 10

[mmeliabit]

Overview Description:

When I run Protonect on Windows I get Info messages during all the execution like these ones:

[Info] [DepthPacketStreamParser] 34 packets were lost
[Info] [TurboJpegRgbPacketProcessor] avg. time: 57.1977ms -> ~17.4832Hz
[Info] [DepthPacketStreamParser] 30 packets were lost
[Info] [DepthPacketStreamParser] 30 packets were lost
[Info] [DepthPacketStreamParser] 24 packets were lost
[Info] [DepthPacketStreamParser] 31 packets were lost
[Info] [DepthPacketStreamParser] 14 packets were lost
[Info] [DepthPacketStreamParser] 26 packets were lost
[Info] [DepthPacketStreamParser] 25 packets were lost

Does this packet loss correspond to the normal performance? I see the Protonect depth image, but not very smoothly.

It means the performance is terrible. You can use CUDA depth processor if you have GPU.

I know this thread was closed a while ago but I have a follow up question regarding packet loss. I have tried running the Protonect example with various settings, -gpu=cuda with and without -noviewer and I am still getting lost packets. Below is an example of the output using -gpu=cuda -noviewer:

Why am I still getting packet loss? Isn't this the fastest way to run the example and process frames? Is this amount of packet loss normal?

Protonect cuda -noviewer?

[wired365]

Woops, I misunderstood the protonect help text. I was using protonect -gpu=cuda -noviewer. I had always wondered why it was still using the openGLDepthPacketProcessor. The weird part is when I run protonect cuda -noviewer I get the LIBUSB_ERROR_OTHER that I was getting a while back. When I don't use cuda it works just fine.

[wired365]

I read the conversation between @xlz and @bn-dignitas regarding my original usbdk issue. My LIBUSB_ERROR_OTHER appears to be resolved by the addition of a pause as suggested in the other thread #812. That aside, when I do insert the pause and get protonect running with Cuda there appears to be pretty sever performance issues:

If you run it individually how much packet loss?

It looks things will work fine when only processing either the RGB or Depth, but there are some performance impacts when processing both.

[xlz]

I noticed you're running Debug build. What is the performance with Release build?

[wired365]

Hmm the performance appears to be intermittent for both Debug and Release. I am now getting up to 25 packets lost per update running the same Debug version with cuda -noviewer -norgb. The release mode appears to be a bit more consistent but still drops packets. The various outputs are below:

I am not sure why performance isn't consistent from run to run. I get runs where there appears to be very few packets dropped and others where it is dropping almost 20+ packets per line. The -nodepth runs do appear to be much more consistent than those involving the depth processing, as in I haven't seen them drop any packets.

[xlz]

I don't know what kind of shell you're using. You can run these commands with the environment variable LOGFILE=protonect.log which provides more information about why packets are lost.

[wired365]

Running with the command protonect.exe cuda -noviewer -norgb I get the following in the log file:

The protonect.exe cuda -noviewer -nodepth looks fine to me, no dropped packets:

The combined protonect.exe cuda -noviewer seems to do better than just depth and outputs the following to the logger:

not all subsequences received means there is something wrong in your usb stack.

Are you running on UsbDk 1.0.16 or .17?
