Description
Incorrect seeking on bbb_sunflower_2160p_30fps_normal.mp4
How to reproduce:
- unpack reproduce.7z to a folder
- copy ffmpeg executable to the unpacked folder
- download http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_2160p_30fps_normal.mp4 from http://bbb3d.renderfarming.net/download.html to the unpacked folder
- in run.cmd modify paths inside CONFIGURATION AREA if need
- execute run.cmd to get test data
- content of "%OUT_DIR%\14270.jpg" should be equal to "%OUT_DIR%\_out.jpg" but it is not true
In short, run.cmd does:
- extract pts_time for all frames via
%FFMPEG_CMD% -i "%INPUT_FILE%" -filter:v showinfo=checksum=False -f null - 2> "%OUT_DIR%\_out.txt"
- inside _out.txt, pts_time for frame n:14270 will be 475.733
- extract frame n:14270 via
%FFMPEG_CMD% -y -ss 475.733 -i "%INPUT_FILE%" -frames:v 1 -vsync drop "%OUT_DIR%\_out.jpg"
- extract all frames via
%FFMPEG_CMD% -y -i "%INPUT_FILE%" -vsync drop -start_number 0 "%OUT_DIR%\%%05d.jpg"
