[Elphel-support] Stream stopping after setting decimation

[Daniele Forsi]

Hello,

when I change the parameters DCM_HOR and DCM_VERT the stream stops and the str daemon can't be stopped with Ctrl-C or kill -KILL and I need to reboot the board (the web server and ssh server are still working).
I have set those parameters to 2, 3 and 4 using the web interface.

This happens both if str is not running and when it is running , in this case the last lines printed are:

streamer.cpp: handler: 366: sensor port: 0 event: running= 0 streamer.cpp: update_settings: 131: sensor port: 0 update_settings
video.cpp: getFramePars: 285: sensor port: 0  before=0 metadata_start=46106528
video.cpp: getFramePars: 285: sensor port: 0  before=0 metadata_start=45742816
video.cpp: get_current_desc: 350: sensor port: 0  fps=2.5
Socket::poll()...
socket.fd == 8; 9;
revents == 0; POLLIN == 1
revents == 0; POLLIN == 1
streamer.cpp: handler: 366: sensor port: 0 event: running= 0 streamer.cpp: update_settings: 131: sensor port: 0 update_settings


after a couple of seconds another line is printed:

video.cpp: getFramePars: 285: sensor port: 0  before=0 metadata_start=41742464

 and then nothing more.

How can we debug this situation?

thanks you
