[Andreas Weber]

Update of bug #43897 (project octave):

                  Status:                   Fixed => Need Info

Follow-up Comment #8:

Okay, I reopen this report. Can you please enable logging (rm previous
logfiles before) with


$ export LIBV4L2_LOG_FILENAME=libv4l2_debug.log


Then run this in Octave:


pkg unload all
pkg load image-acquisition
obj = videoinput("v4l2", __test__device__);
set (obj, "VideoFormat", "RGB3")
start (obj, 1)
img = getsnapshot (obj);
imwrite (img, "out.jpg");
stop (obj)


Then run streamer with -b 1 (only one buffer as the script above does) and the
run the Octave script above a second one. As I read from the description the
first run fails, streamer succeeds and the second try in Octave also succeeds.
Please attach the generated libv4l2_debug.log
