cannot open a video file!

Hi,

In installed the code successfully (with make) but when I use "make runtest" to see if everything is ok I get this error message: . . .

with ignoring the above error in "make runtest" , I tried to run examples/c3d_ucf101/ but it gives this error:

I checked the system for opencv and ffmpeg and everything seems is working!. I don't have any idea what's the problem.

Hmm. make runtest should pass as it is in Travis (https://travis-ci.org/chuckcho/video-caffe). So, I would have to suspect opencv is not behaving.

@mzolfaghari I encountered the same problem like you. I want to know how did you solve it? Thank you very much!

[chuckcho]

Will revisit if this continues to occur.

I have the same problem now. I am running with mode: CPU_ONLY=1, no Cudnn (use_CUDNN=0) since my laptop don't have GPU card, does this cause the problem? Any suggestion? Thank you.

[chuckcho]

@nvanthuy Currently video-caffe requires a GPU (CUDA/CuDNN)

[deepaksharma36]

I am also experiencing the same issue, @haohao900618 how did you manage to fix it?

[ljpadam]

I met the same problem. @chuckcho How could we solve this?
