Re: GStreamer from ssh

Most likely it's autovideosink making a different decision as to how to render. Does it work through fbdevsink if you don't have X running? Testing on a Pi4 and both have worked fine. Thanks, that does seem to get me closer to my goal. Is fbdevsink a newer plugin? I don't remember seeing that the l...

I have a Pi 3 with the latest Raspbian. I'm trying to do something that was really simple the last time I did it (Pi 2, Wheezy).

Re: SSH using hostname unreliable

I've been using it for some years now, from Win7 to Pis (PuTTY, pscp, and--recently--VNC), Pis to Pis (ssh and pscp) and it's been reliable. What OS are you running? I'm running Win10 Pro 1909. I've also been using it for years, though with PI 2s. And I thought this Pi worked better on a different ...

I've been using rpi-clone to make copies from a Pi I've been using for development. It works great, but I was hoping that I could do something like this over the network. It'd make maintenance a lot easier if physical access wasn't required. And I'm not talking about just doing apt-get update or upg...

I'm very close to having my video conferencing project working. But I'm having some serious audio latency. In the order of seconds, which obviously isn't good for conferencing.

Strange. I went to run this again and I have around 15% cpu. I think the only thing I did was record a test with arecord. Maybe that caused something to change.

Wolfson CPU usage

Just getting started trying to use my Wolfson card. I have a very simple gstreamer pipeline and I'm wondering why I have nearly 100% cpu.

Code: Select all

 gst-launch-1.0 -v alsasrc ! fakesink
Is high CPU usage to be expected?

Re: Best approach for movie with text overlay

Yeah, but without the overlay there is almost zero delay. I do want to encode to h264 in a single pipeline, but this is a video conferencing application with a time overlay (and possibly other text). The delay just isn't great and neither is the low resolution. Doing everything but the overlay works...
