Description
Encoding a UYVY avi file
lossless_h264_encoding.avi
using lossless encoding (libx264) and then decoding it back to an avi file
lossless_h264_encoding_check.avi
then the resulting video is different from the original one.
Sample files are on upload.ffmpeg.org.
I am using a recent windows binary (ffmpeg-20130115-git-5ce023b-win64-static), and the following command lines:
<..>\ffmpeg-20130115-git-5ce023b-win64-static\bin\ffmpeg.exe -v 9 -loglevel 99 -i lossless_h264_encoding.avi -c:v libx264 -profile:v high444 -crf 0 lossless_h264_encoding.h264 <..>\ffmpeg-20130115-git-5ce023b-win64-static\bin\ffmpeg.exe -v 9 -loglevel 99 -i lossless_h264_encoding.h264 -f avi -pix_fmt uyvy422 -vcodec rawvideo lossless_h264_encoding_check.avi
Following are the command lines used including output:
<..>\ffmpeg-20130115-git-5ce023b-win64-static\bin\ffmpeg.exe -v 9 -loglevel 99 -i lossless_h264_encoding.avi -c:v libx264 -profile:v high444 -crf 0 lossless_h264_encoding.h264
