Stream crashing #7

Closed lbr38 closed 5 years ago

lbr38 commented 5 years ago

Hi,

I had the stream working for all day, and tonight it crashed. I tried to stop and start it again and now it still crash (loop) :

Also some logs from kern.log :

The command I used : ustreamer --device=/dev/video0 -r 1280x720 -f 30 -m JPEG --host 0.0.0.0 --port 8888 2>&1 | tee /home/pi/scripts/ustreamer-live.log &

I'm pretty sure it will work again if I reboot the RPi but have you got something to "reset" the camera or something without rebooting ?

mdevaev commented 5 years ago

I think you can remove uvcvideo and laod it again: rmmod uvcvideo && modprobe uvcvideo.

Also try to append dwc_otg.fiq_fsm_mask=0x3 to /boot/cmdline.txt and reboot. I think it will have to help.

When you restart, after the timeout did the program exit?

lbr38 commented 5 years ago

Okay so I had the same crash today, here are the logs before killing the program. Those logs are looping and the black No signal page is diplaying on the stream:

Continue looping until I kill the program

So I tried to:

Nope it doesn't exit and try to restart the capture (logs above)

For the moment the only way to get the camera and the stream working again is to reboot the system.

Also try to append dwc_otg.fiq_fsm_mask=0x3 to /boot/cmdline.txt and reboot. I think it will have to help.

Ok I will test this ;-)

Thank you for your time and help, I don't know if there is a solution for those crashs maybe the camera is too buggy..

mdevaev commented 5 years ago

Random crashes always mean a problem with hardware or drivers. Sometimes you can make a simple workarund in software for this, but sometimes there’s no easy solution.

lbr38 commented 5 years ago

Still haven't found a solution.. the stream works for 1 day then it crashes :(

Saw many threads on the internet, everybody seems to have this problem since years, and nobody ever found a real solution except rebooting the system. I'll have to make a script that monitors the stream and reboot the system if the camera crashes. This is a bit frustrating to do it this way but there's no other way.

Anyway ustreamer works like a charm, you did a nice job! :)

mdevaev commented 5 years ago

Thanks! :)

It looks like it's still in the driver. Unfortunately, I have no way to debug it. If you find out any solution in the future - please let me know about it.

xmmwc commented 4 years ago

I solve it by set --device-timeout to 2 sec just wait longer

lbr38 commented 4 years ago

Indeed it seems to work fine with timeouts!

-- ERROR [61756.456 stream] -- Mainloop select() timeout -- INFO [61756.456 stream] -- Destroying workers pool ... -- INFO [61756.472 http] -- HTTP: Freezing last alive frame forever -- INFO [61756.586 stream] -- Capturing stopped -- INFO [61756.603 stream] -- Device fd=8 closed

But will see if it works on long term and how it deals with "I/O errors" and "Can't open device" errors (which need to reboot the system to get the camera back in my case)

Thanks for the info and thanks @mdevaev for this new feature :)
