Mainloop select() error: Success #256

Assassins88 · 2024-02-09T19:31:00Z

I get the following error:

This advertisement repeats itself over and over again.

I run the standart command without parameters.

The system runs in a Proxmox VM without a GPU so i cant use hw encoding and MJPG...

Which capture device do you use?

Assassins88 · 2024-02-09T19:52:39Z

Which capture device do you use?

I'm sorry, but what do you mean exactly?

mdevaev · 2024-02-09T21:08:53Z

Tell me how you launched ustreamer, which video capture device (camera?) you use it. More information, I don't understand what's going on.

Assassins88 · 2024-02-09T21:30:11Z

Tell me how you launched ustreamer, which video capture device (camera?) you use it. More information, I don't understand what's going on.

I launched it with different commands:

./ustreamer

./ustreamer --device=/dev/video0 --host=0.0.0.0 --port=80 -m YVYU

./ustreamer --device=/dev/video0 --host=0.0.0.0 --port=80 -m mjpeg

with the mjpeg parameter comes a error that my device dosnt support hw encoding...

my cam supports the following formats:

The cam is a cheap Hama webcam but it works with MJPG-Streamer.

Which message exactly?

Then I don't know what the reason may be, sorry. I don't see any visible difference with mjpg-streamer with select() and I don't have cameras with the same glitch.

I get the same error using PS3 Eye camera

Description: Lightweight and fast MJPG-HTTP streamer
 µStreamer is a lightweight and very quick server to stream MJPG video
 from any V4L2 device to the network. All new browsers have native
 support of this video format, as well as most video players such as
 mplayer, VLC etc. µStreamer is a part of the Pi-KVM project designed to
 stream VGA and HDMI screencast hardware data with the highest resolution
 and FPS possible.

If any other logs would be useful, let me know, I can also test stuff if you would like me to do so :)
(dmesg and journal are both clean)

You're using a very old ustreamer release, please build it from git and test again.
