  ffmpeg ffv1 lossless question-

  Posted by Ryan Smith on May 12, 2011 at 11:48 pm

  Hi-

  I am attempting to encode a tif sequence using ffv1 lossless compression. Upon encoding to FFV1 and decoding back to TIF, my image is not identical.

  I am able to encode fine using the following command:

  ffmpeg -f image2 -i c:/LTTemp/%03d.tif -vcodec ffv1 out2.avi

  I can then take that avi file and extract it back into a tif sequence using the following:

  ffmpeg -i out2.avi c:/LTTemp/2/image%d.tif

  I get a warning that my original tif image is PAL8 and will be converted to YUV420P which I believe to be my problem, however I am stuck on how to remedy this. My input image type is a 2D unsigned char tif written to disk using ITK. Thanks in advance-

  -Ryan
