Jitsi on RPi4


Dan Romanchik KB6NU
 

I recently installed HamPi on my RPi4, and it's been working great. I've been using the RPi as an Arduino development station, and I recently purchased an SDR dongle to play around with the SDR programs and maybe try a little GNU Radio.

Yesterday, I wanted to show off this setup to a couple of ham friends that I meet once a week via Jitsi at lunchtime. I plugged the Logitech camera into one of the USB ports, fired up the web browser, and connected to the Jitsi meeting just fine, and I could see my friends and they could see and hear me just fine, but their audio was garbled and almost not understandable.?

One thought I had is that I'm connecting to the internet via WiFi, and perhaps the WiFi connection just couldn't handle all the data. The video, though, looked just fine. Anyone else use Jitsi on the RPi4? Any thoughts on how I can get this to run better?

Thanks & 73,

Dan KB6NU

Perhaps a swap file for cache.

Determine what services/daemons are running as HAMPi has many apps involved. You may be able to de-install or stop unwanted/unused apps.

Reduce the level of detail in the video stream, if possible.

Also, google the UNIX 'nice' command, and see if you can prioritize resources for the audio/video during meetings.

As you mentioned, try a wired connection that is as fast or greater than you ISP connection.

Per Jerry's suggestion, what speed is your SD card? It may be the bottleneck...perhaps try a? faster SD card, or use a USB 3.0 HDD/SSD in lieu of the SD card.
