I am loading a video but I get an empty array as an result. I do not receive any error messages. Below you can see when I call VideoReader.
>> vidObj = VideoReader(filename)
vidObj =
VideoReader with properties:
General Properties:
Name: 'filename.mov'
Path: '~/filepath'
Duration: 31.2110
CurrentTime: 0
Tag: ''
UserData: []
Video Properties:
Width: 0
Height: 0
FrameRate: 0
BitsPerPixel: 0
VideoFormat: ''
As you see some metadata about my video are zero. I also can't gate frame number. What am I doing wrong?
Ubuntu 14.04 LTS, MATLAB R2015a Many thanks, bedi

Hi, did anyone solved that problem? I checked the formats supported for my system and everything is ok but I still get zero properties.

Weel,
I have the same problem as Nicole, I checked the supported formats (I'm working with high speed footage from iPhones 5 and 6) and they are mentioned as being supported, but still I get only zero for CurrentTime, which a bit annoying since I'm working on multiple camera synchronisation and want to identify missing frames.

I understand that you see zeroes for the Video Properties. Video Reader supports file formats depending on the Operating System that you are working with. On executing the following line at the MATLAB command prompt, you can see the file formats that the OS supports.
formats = VideoReader.getFileFormats()
Please refer to the following link for more information VideoReader supported formats
