vdev | A device-file manager for * nix

I tried running the DPDK ipsec-secgw sample app with the following versions

• DPDK version dpdk-stable-19.11.5
• OS CentOS Linux release 7.7.1908 (Core)
• Kernel 3.10.0-1062.el7.x86_64

NIC type and driver

• 0000:00:04.0 'Virtio network device 1000' drv=igb_uio unused=virtio_pci,uio_pci_generic

Command and cmd line args used to run the app

• Pktgen version 21.01.0
• DPDK version 20.11
• OS: ubuntu 18.04
• NIC: Mellanox

I'm trying to make a username available once a user deletes their account. By default the username is unique meaning the username won't be available even after the account is soft deleted.

This is, by default, the setup that comes with django out of the box.

I could not tell from the documentation if it is possible to use vdev rx_pcap to simulate RSS with a pcap file, using multiple cores.

It seemed like an interesting proposition, after reading this:

For ease of use, the DPDK EAL also has been extended to allow pseudo-Ethernet devices, using one or more of these drivers, to be created at application startup time during EAL initialization.

To do so, the –vdev= parameter must be passed to the EAL. This takes take options to allow ring and pcap-based Ethernet to be allocated and used transparently by the application. This can be used, for example, for testing on a virtual machine where there are no Ethernet ports.

Pcap-based devices can be created using the virtual device –vdev option.

This is how I read one PCAP file and write to another, using their example with the dpdk-testpmd application:

I'm trying to use dpdk-pdump capture tx packets from NIC under dpdk control.

• DPDK 18.11.4
• In config/common_base, CONFIG_RTE_LIBRTE_PMD_PCAP=y and CONFIG_RTE_LIBRTE_PDUMP=y are already set
• After rebuilding, CONFIG_RTE_LIBRTE_PMD_PCAP=y and CONFIG_RTE_LIBRTE_PDUMP=y are also set in x86_64-native-linuxapp-gcc/.config
• rte_pdump_init(NULL) and rte_pdump_uninit() are called in primary process's init and destroy function
• DPDK interface

I am trying to get the camera feed from a blackmagic capture card into the mediaplayer of the Vlc plugin for Unity.

What i have done :

• I can get the capture device with the vlc desktop application, so camera and capture card work fine.

• I can run the sample scene of the vlc plugin which show an video from a web url, it works fine

• I searched the LIBVLCSharp to try to understand a bit how it all works, https://code.videolan.org/videolan/LibVLCSharp/-/blob/master/src/LibVLCSharp/Media.cs
• I am trying to modify the UseRenderingPlugin.cs, which is a script which plays the video on a texture in the Unity scene, and especially the line which chose the media to be played :

The original line of code : _mediaPlayer.Media = new Media(_libVLC, "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4", FromType.FromLocation);

And what i achieved so far (but doesn't work). I changed 'FromLocation' to 'FromPath' and replace the URL with the mrl to the capture card with the options, thanks to the vlc desktop application :

I want to use vlc command line tool to capture a video from a usb camera (on Windows!). The Problem is that is not clear, when to stop recording. The aim is to capture the users face, while he is running the program. It is important to have correct timing. I am launching vlc like this:

Ubuntu 16, DPDK 16

I have a couple of DPDK-based applications sending packets between two machines and want to capture them with dpdk-pdump. I'm running it with sudo ./build/app/pdump/dpdk-pdump -c 0x00f -- --pdump 'port=0,queue=*,rx-dev=/tmp/rx.pcap', and I see this output and a crash:

EAL: no driver found for eth_pcap_rx_0 EAL: Driver, cannot attach the device EAL: Error - exiting with code: 1 Cause: vdev creation failed:create_mp_ring_vdev:736

My DPDK was compiled like this: hostname:~/dpdk-stable-16.07.1/x86_64-native-linuxapp-gcc# CONFIG_RTE_LIBRTE_PMD_PCAP=y make (also did export CONFIG_RTE_LIBRTE_PMD_PCAP=y before) so that it builds with libpcap support, as the documentation said to do. And my system has libpcap installed. The make script output shows == Build lib/librte_pdump. Looking around online, I've only found one person with a similar issue, and the suggested fix was what I tried. Is there something else I have to do?

I tried installing the DPDK Ubuntu package's version of the tool and using the dpdk-pdump command, same result.

I am trying to stream and RTSP video only stream from my webcam and consume the feed inside a VM (Docker container) on the same machine.

Here are the commands line args I'm using:
