Forced to rmmod/modprobe after using bmdcapture about bmdtools HOT 8 OPEN

If you use the example code it works fine?

If I Ctrl+C and then restart the process, it just won't work unless I
reload the firmware module.

I'm not sure what you mean by example code.

I used this:
nonius@avip-encoder:~/bmdtools$ ./bmdcapture -m 13 -C 0 -V 3 -F nut -o "strict=experimental:syncpoints=none" -f video.raw
Fri Nov 21 18:54:22 2014
Frame received (#1) - No input signal detected - Frames dropped 1 - Total dropped 1
Fri Nov 21 18:54:22 2014
Frame received (#5) - Input returned - Frames dropped 2 - Total dropped 2

If I Ctrl+C and run it again it doesn't work.

if you try running the example code provided with the drivers, do you have
the same problem? there is a Capture program you can build.

Capture seems to be expecting SDI because it keeps saying
Frame received (#0) - No input signal detected

Though after the first run the second ./Capture command doesn't work either.

rmmod/modprobe also fixes the second not working ./Capture command.

media express works fine? I'm tempted to think that the problem is in the
driver if even mediaexpress has the same issue.

I'm using a baremetal server without any GUI. I suspect Media Express would be the same. I'll try it later when I have some spare time to install x11.

I'm having several issues now with this firmware. bmdcapture shows me a clean raw picture, but ffmpeg 1.2.10 doesn't seem to parse it very well. I get half of the video with green lines.

VLC 2.1.5 simply blows up with a segmentation fault under
[ 4330.629950] vlc[4610]: segfault at aac3d000 ip aac3db1a sp b67330d0 error 7 in libyuy2_i420_plugin.so[aac3d000+3000]

One year ago I had more luck with both :), regressions aren't that welcoming.

Do not use ffmpeg. I do not support it in any way. the code is developed using Libav.

from bmdtools.

Don't worry. The problem was the libswscale. I compiled VLC with it and the picture is crystal clear.

This problem still remains though. I used VLC with decklink support and the same is happening so this might be related to drivers after all.

I'll try to check with mediaexpress.
