[Elphel-support] strreaming problem...

Carlos,

"Top"s look ok. I also tried a camera with the 8.1.2 firmware and my PC -
streaming works at 1920x1088.

Sorry, I forgot to ask you to check a few more things:

1. You should have a usb-serial cable - could you connect it and send us
the camera boot log? And also the info the camera writes when the streamer
is working.
2. Command "top" right after the boot + before/after you launch
mplayer could be helpful.

Best regards,
