Different file size and frame drop warning when reading RAW DV input file #8

Open tvasenin opened 5 years ago

tvasenin commented 5 years ago

I always get a single-frame warning when trying to process previously captured RAW DV file. Reproduces for every RAW DV file I've tried!

Also, if I run the same command multiple times, the capture result is sometimes different.

Consider this file:

DV Analyzer v.1.4.2 by AudioVisual Preservation Solutions, Inc. http://www.avpreserve.com

<path>\dv-02--2005-06-18.dv

Frame Count: 239

Absolute time   DV timecode range           Recorded date/time range                            Frame range
00:00:00.000    00:00:00:17 - 00:00:10:05   2005-06-18 19:52:44     - 2005-06-18 19:52:53              0 -      238
