How do I read an MP4 file? VideoReader gives the following error "Failed to initialize internal resources."

Error using VideoReader/init (line 619) Failed to initialize internal resources.
Using Windows 10, MATLAB R2016A, recorded the .mp4 stream out of a Cornet encoder (H.264) using VLC, which is a format MATLAB help says it can read. Any advice is helpful. thanks

I have Matlab R2018b on Debian Stretch Linux and get the same error when trying to read files of avi format. (avi is supported) - gstreamer installed and in the latest version. How do I add support to read .MOV and .mp4 files?

I understand that the error "Failed to Initialize internal resources" pops up when trying to use the 'VideoReader' function in Windows 10, MATLAB R2016A.
There could be various reasons behind this error which are listed as follows:
  1. The required codec is missing for the particular video file. Determine whether the codec is installed on the computer.
  2. The video file contains an audio stream (eg. AC-3) not supported by the API (QTKit, in AC-3 case) used by VideoReader. The only workaround is to re-encode the audio stream in the file into a different format such as MPEG-4/AAC and then try to read the file.
  3. Sometimes, VideoReader cannot open a video file for reading on Windows platforms. This might occur if you have installed a third-party codec that overrides your system settings. Uninstall the codec and try opening the video file in MATLAB again.
The supported container formats and codecs link explains supported codecs in detail. Go through the troubleshooting section to determine if that could be a possibility in this particular case.
Hope this helps!
