Как я могу удалить X секунд с начала видео, используя ffmpeg?
Что я пробовал:
ffmpeg -ss 00:00:10
ffmpeg -ss 10
ffmpeg -ss "11" -i season.avi -vf "movie=/storage/conv_sctipt/watermark.mov [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10, fade=in:0:20 [out]" -map 0:0 -map 0:1 -y -acodec libfaac -ab 64K -ac 1 -vcodec libx264 -b 555K -bt 666k -threads 0 "season.flv"
Затем я получаю следующие ошибки, и ffmpeg продолжает:
