OS requirement to install AVB #29

Closed sinlam closed 3 years ago

sinlam commented 3 years ago

May I know which Linux distribution should I use, to try the tutorial "Getting Started with AVB on Linux"? I tried Ubuntu 20 and faced some issues, the kernel version 5.8.0 is different from the document. Thanks for any info!

Hi @sinlam,

Can you describe the issues you are facing? I'd expect that anything after 19.10 would Just Work (TM).

Hi @edersondisouza, Thanks for your message. I tried to install AVB in Ubuntu 20.04.2, after installed alsa-lib with the git version v1.1.9, immediately after reboot my sound output device become Dummy Output.

If I use the latest source for alsa-lib, alsa-utils and alsa-plugins, the sound device is ok. But I encountered no tone heard in the AVB Audio Talker/Listener Example using Alsa Framework.

I also tried AVB Video Talker/Listener Example using Gstreamer Framework using single machine only, no video is displayed in the listener screen. Do I need to install VLC or other software?

Can I check if the examples will work in single machine with Intel i210 card? Hope to hear your suggestion! Thank you!

edersondisouza commented 3 years ago

Hi,

Just to be clear, is your setup a single machine, or two machines and just one with the i210? Assuming the second scenario, you can test using the i210 one as talker. But note that you won't get PTP to sync both machines. For a single machine, options are quite limited.

Hi @edersondisouza, My setup is two machines (Intel NUC Hades Canyon and Ghost Canyon), each machine has two network ports: i210 port and i219 port. I tried Debian 10 with Kernel 4.19 and use only Console login without UI for both machines. I installed Alsa Plugin and GStreamer Plugin (gstreamer, gst-plugins-base, gst-plugins-bad, gst-plugins-good, gst-plugins-ugly, gst-libav, gst-vaapi, gstreamer-vaapi) from source. Tested aplay and the sound is detected.

The two machines connected to my router using i219 ports, and connect to each other using network cable on i210 ports. For each machine, I setup static IP for i210 port, create VLAN 5 with another static IP. Then I setup Qdiscs configuration from the documentation. PTP Time synchronization using PTP is working for the two machines.

When I tried to run AVB Audio Talker/Listener Examples using Alsa Framework, the 'speaker-test' and 'arecord/aplay' run fine but I cannot hear the sound in the listener machine.

I also tried to run AVB Audio Talker/Listener Examples using GStreamer Framework, both 'gst-launch-1.0' run fine but I cannot hear the sound in the listener machine.

Finally I tried AVB Video Talker/Listener Examples using GStreamer Framework, the talker 'gst-launch-1.0' run fine, but the listener failed to run because 'vaapih264dec' is not found. I changed it to 'avdec_h264' and there is a core dump.

So I failed to run all 3 examples, hope you can give some hints how to fix these issues. Thank you!

Hi @sinlam,

Thanks for the description of your setup. It does look that it indeed should be able to run the samples. Note that the examples are on layer 2, so no need for the IP layer for them.

Some tests that can help bring more light on what is going on:

sinlam commented 3 years ago

Hi @edersondisouza, Sorry for the late reply as I only have some time to troubleshoot it during the weekend. Below is the tests of the log that is running with GST_DEBUG=avtp*:6 sudo -E gst-launch-1.0 (...), and I also skip ETF setup step on both the talker/listener. I got the same result, i.e. no audio is heard from the Listener host. Please let me know what I can do further test. Thank you!

Hi,

Note that the address parameter usually describes the multicast address that both Talkers and Listeners join to transmit some stream. However, you are defining each machine own MAC address - so, each is roughly listening/talking to itself. Try removing the address parameter altogether - avtpsink and avtpsrc will simply fallback to multicast address 01:AA:AA:AA:AA:AA and things should just work. In case you want to define your own multicast address, I suggest taking a look at https://en.wikipedia.org/wiki/Multicast_address#Ethernet.

If you want to use unicast address, then you should, on the talker, give the address to the listeners - and on the listener, use it's own address - but you usually don't want to do that, as it has some implications when using routers along the way.

Hi @edersondisouza, thank you for the detailed explaination. It really helps! Now I can run both Talker / Listener example using ALSA framework and GStreamer plugins. Thank you for your time!
