Comment (by MkMs):
First log (ffmpeg-20140731-105226.log):
Using the quantization to get a video version of lower quality (with
artefacts)
Second and third log ( ffmpeg-20140731-110030.log &
ffmpeg-20140731-110030.log):
Show/ Check only the absolute number of frames - unnecessary for
programming, only to show the possible bug. Even without
{{{
-pix_fmt yuv420p
}}}
I get one more frame (84 frames than in original "baumgartner.mp4")
You are using libx264?
{{{
ffmpeg.exe -i baumgartner.mp4 -c:v libx264 -q:v 32 -pix_fmt yuv420p
baumgartner_qp32.mp4
}}}
