Hi I am having big trouble to read video using matlab in Ubuntu 16.04. When I try to read any format of video I get this error
Error using VideoFileReader/setup
Could not open the specified file.
I have installed all the gstreamer plugin to and I have changed matlabroot/sys/os/glnxa64/libstdc++.so.6 with my /usr/lib/x86_64-linux-gnu/libstdc++.so.6
Last time when I installed matlab in my Ubuntu system the above method solved the problem but this time no work. I need help.
Sometimes i used to get this error to:
Error using dspmmfileinfo>tryVideoReader (line 278)
Failed to initialize internal resources. The specified file is:
/home/mofiqul/repos-git/Image-Processing/matlab/multi-object-tracking/video4.avi

I'm using AppDesigner in MATLAB, and whenever I use imread() function inside a button this error message displays:
Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 335)
Error while evaluating Button PrivateButtonPushedFcn.
When I put a breakpoint on imread() line I found the entire error message:
Caught "std::exception" Exception message is:

I am attempting to run the mnist example in matconvnet using parapooling. I have allocated 2 gpus, but it shows this error while trying to run cnn_mnist_experiments:

Apparently, the workers cannot get access to "vl_cudatool" file. What could be the issue here?
Undefined function 'vl_cudatool' for input arguments of type 'single'.
It means that your vl_cudatool function is not in your path
try
which vl_cudatool
I don't know what vl_cudatool is. Maybe you can try some earlier version of MatConvNet?
I run the demo code of RCNN with matcaffe, but I met an error which confused me for a while:
Error using caffe
Unknown command 'get_weights'
Error in rcnn_load_model (line 36)
rcnn_model.cnn.layers = caffe('get_weights');
Also, I check the directory of caffe matlab, there is not get_weights function. Do anyone know how to solve that? Thank you.
I am trying to use the normalized cuts package from [http://www.cis.upenn.edu/~jshi/software/Ncut_9.zip][1] (on Windows 7 - MATLAB R2010a 32 bits), but it's not working. I'm trying to run the demo called "Ncut Clustering demo" and I got the following error:
??? Undefined function or method 'sparsifyc' for input arguments of type 'double'.
Error in ==> ncut at 41
W = sparsifyc(W,dataNcut.valeurMin);
Error in ==> ncutW at 9

I already put the NCUT9 dir in the path so this is not the problem I guess, and I already compile the MEX files with the command: compileDir_simple(mydir).
I have downloaded and installed NCTOOLBOX into MATLAB (2013a) to read netcdf and grb files. As a test, I copied a netcdf, grb and grb2 file to a directory on my computer. This is placed within my script as:
pathnc = 'c:\test\era40_moda_200205.nc'
pathgrb = 'c:\test\era40_moda_200205.grb'
pathgrb2 = 'c:\test\multi_1.at_4m.dp.200607.grb2'
I used the following code to read the *.nc file:
nc = ncdataset(pathnc);
nc.variables
The code works great....with no error messages..and all variables listed..on netcdf files...... however, when I run it for the grb files using:
nc = ncdataset(pathgrb);
nc.variables
I get this very long list of errors:
2014-03-05 08:40:15,744 [main] WARN ucar.nc2.grib.grib2.Grib2Index - Grib2Index bad size = -1 for c:/test/multi_1.at_4m.dp.200607.grb2 index = c:\test\multi_1.at_4m.dp.200607.grb2.gbx9

Java exception occurred:

In case it was just a bad file, I tried the code on a different grb file and got the same results. Yes I have read the previous posts on reading grb with NCTOOLBOX...but still 'dead in the water.' I would greatly appreciate any insight to get my script reading grb and grb2 files.
I was getting a similar java error: java.lang.NoSuchFieldError:alwaysUseFieldBuilders. I tried running the same code in R2014a and it worked.
