Estoy intentando poner una marca de agua en un video usando FFmpeg y -vf para superponer un PNG, pero no funciona.
Mi línea de comando:
$ffmpeg->exec('-i "' . $path_src . '" -vf "movie=watermark.png [wm]; [in][wm] overlay=0:0 [out]" -map_chapters -1:-1 -threads 2 -ar 44100 -ab 96k -vcodec libx264 -level 41 -crf 25 -bufsize 2000k -maxrate 2500k -r 25 -g 250 -s 720x480 ' . '-coder 1 -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -flags2 +dct8x8+bpyramid -me_method umh -subq 7 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -rc_eq \'blurCplx^(1-qComp)\' -bf 16 -b_strategy 1 -bidir_refine 1 -refs 6 -deblockalpha 0 -deblockbeta 0 -y "' . $path_dst .

Su versión de ffmpeg (0.6.1/2010) es un poco antigua, es posible que el formato de la línea de comando haya cambiado desde que salió.
