mjpeg-streamer-r63 does not build on armbian

Fredrik — Thu, 18 Jan 2018 07:56:15 -0000

downloaded the latest from sourceforge (1c424b5441a2bf8379cdecd7dbebc935 mjpg-streamer-r63.tar.gz).
It does not build on armbian (5.37.180112 for Orange Pi PC+)
A missing struct, a changed define, and libraries after objects.

mjpg-streamer segfaults when using -y (YUV) option.

Paul Brand — Tue, 23 Dec 2014 09:18:27 -0000

Im trying to stream a webcam using a vocore system.
http://vocore.io/

When i use the following command:

mjpg_streamer -i "input_uvc.so -d /dev/video0 -r 320x240 --fps 2" -o "output_http.so -w /www/webcam"

mjpg-streamer seems to run fine, but because there is no mjpeg support by the webcam nothing shows on the website. debug below:

http://pastebin.com/StenGmbe

When i use -y (YUV) command:
mjpg_streamer -i "input_uvc.so -d /dev/video0 -r 320x240 --fps 2 -y" -o "output_http.so -w /www/webcam"

mjpg-streamer fails, debug below:

brightness control by control.html has bug

lunahuang — Mon, 22 Sep 2014 11:07:32 -0000

when modify web camera brightness by control.html we can find a bug.
When web camera(Microsoft Corp. LifeCam VX-2000) brightness rage from 16 to -16
Decreasing brightness by "brightness -" button to meet brightness value -1 then press "brightness +" to increase brightness would fail to increase.
Because on v4l2GetControl return control_s.value=-1 but on v4l2UpControl and v4l2DownControl decide -1 is error number.

#32 Going from stream to snapshot and then back to stream crashes mjpg_streamer

oddree — Tue, 29 Oct 2013 17:21:48 -0000

Hello Marton, thanks for looking into this. I am not sure if this is possible - but I think it may be the client that is causing the problems. I found that if I run the feed over HTTP to Firefox, it starts consuming a lot of memory and becomes unresponsive. When I am able to kill firefox, it doesn't seem to release the feed (continues running server side to a disconnected client).

If I used VLC to monitor the feed I can have it up for hours without any problems. I can also stop and start streaming throughout the day without any effect on the server side.

So perhaps Firefox is doing something strange?

#30 UVC capturing uses a lot of memory

Márton Miklós — Sun, 27 Oct 2013 11:49:24 -0000

If I add an option to the input_uvc which could be used to specify the buffer size would statisfy your needs?
