[FFmpeg-user] dpx image sequence to ffv1 mkv issues

I updated the Windows build for ffmpeg and at least the error doesn't show up. I still get the warning of:

Cannot allocate worst case packet size, the encoding could fail.

However, after wrapping the 6k 16bit dpx sequence into ffv1.mkv and de-wrapping again into dpx, the checksums
are the same, so it's a good thing.

The last issue I came up to was the DPX version. My original DPX file is DPX version 2, but after de-wrapping MediaInfo shows they are DPX version 1. Checksums are identical, however.
