Bug in seek mechanism for audio in Windows 8 and above RRS feed

  • Question

  • This seems to be a pretty big bug and I ran into it while testing MFCopy on both Windows 7 and Windows 8/8.1

    The bug is in seeking timestamps for audio.

    Take the sample file here:

    https://drive.google.com/file/d/0Bxyb9Iftjh4DQXpNSFRJbzB5dnc/view?usp=sharing

    On Windows 7 run with this file for this sample seek time:

    MFCopy -s 12000 <Input file> <Output file>

    The nearest timestamps received for audio would be 83191382 and video would be 85440333

    On Windows 8/8.1

    The nearest timestamps received for audio would be 100141269 and video would be 85440333

    This leads to trim errors.
