New submission from Martin Wood-Mitrovski <[EMAIL PROTECTED]>:
sample video uploaded to ftp :
wmv_decode_wrong_duration/converted_video_has_wrong_duration_and_video_starts_late.wmv
when trying to convert the above video the output has incorrect duration (extra
9 or so seconds) and the video 'hangs' at the start.
The audio output is fine.
ffplay -stats says this :
