Hallo,
when I am trying to open a .mpg file with the vision.VideoFileReader with
vid = vision.VideoFileReader (videoName, 'ImageColorSpace', 'RGB','VideoOutputDataType',...
'single');
I get the following error message
Error using coder.internal.errorIf (line 9)
Unable to read video from the file. Use dsp.AudioFileReader to read
audio content.
I tried to open a .mp4 file with the vision.VideoFileReader and it works without any problem.
I have already searched the internet for a solution, but I found nothing that solves the problem.
Any ideas?
Thanks, B

Barbara,
Which platform are you on? If on Windows, can you check if you are able to open this file using Media Player?
What kind of MPG file is this? MPEG-1, MPEG-2? Do you have any additional codecs installed on you system? Also, would it be possible for you to share your file?

Hi There! I have faced with the same trouble. As I understood that it is about VLC Media Player because 32 and 64 bit versions of it make differences. For my idea, the code requires 32 bit of it but we do not have it. Best practice is using Media Player because on Program Files we do have both versions of Media Player as 32/64 bits.
I converted my .avi to .mp4 and I could work on without problems. Good luck!
