When we are using to classify videos using deep learning, after the loading of pretrained data and also hmdb_51 org datafolder then we use like this for example, " [files,labels] = hmdb51Files(dataFolder);".
from where we got or create hmdb51Files? how we create files?

Best Answer

openExample('nnet/ClassifyVideosUsingDeepLearningExample')
Once you do that, hmdb51Files will be a function on your path.
The original of it is at 
fullfile(matlabroot, 'examples/nnet/main/hmdb51Files.m')
Note that this example is new in R2019a, and requires the Deep Learning Toolbox
