Timestamp information of MP4

I want to ask for an easy way to get the timestamp information of a mp4 file. (Sorry that I am not familiar with codec.)

I am reading the Tobii Pro Glasses SDK document that explains how to synchronize frame with eye tracking data, where they use a terminorlogy called VTS. Goolge cannot find the exact meaning, so I want to ask for what VTS really stands for and how to get it from a mp4 file. Thanks very much!

Solution

  • You can use ffprobe.exe as follows: 

    ffprobe -i 396025.MP4 -show_packets

    Refer to https://www.ffmpeg.org/ffprobe.html
