[FFmpeg-user] No video only audio in the output file

[richard nirmal singh]

Hi All,

 I am new to FFMPEG trying to convert video to mp4 format along with
watermarking and creating thumbnail images from video. When executing below
command thumbnail images are created but the output mp4 file has only audio
in it. If I remove the watermarking command it creates thumbnail image and
video file correctly or if I remove thumbnail creation option it creates
video with watermarking. Can any one help me to find whats wrong with my
command.

ffmpeg.exe -loglevel warning -y -i MHPDV000195.mpg -i
WaterMark642x352_new.png -r 1/10 -s 500x376 -f image2
OTMM__OUTPUT__FILE%4d.jpg -s 640x352 -aspect 16:9 -r 29.97 -b:v 800000 -b:a
96000 -ar 48000 -filter_complex "overlay=W-w-0:H-h-0" MHPDV000195-O.mp4
