Hello ffmpeg users.
I use the following cmd to convert an avi file to be a mp4 file:
ffmpeg -y -i './scs0707.avi' -acodec aac -ac 2 -strict experimental -vcodec
libx264 -preset slow -profile:v baseline -level 30 -threads 0 -report -b:a
192k -maxrate 1500K -bufsize 1500K -b:v 1300K -pix_fmt yuv420p -f mp4
'./scs0707-1.mp4'
But scs0707-1.mp4 file comes to be Constant Frame rate mode. ( Plz see below
results )
Is there any way to specify the Variable Frame Rate mode in ffmpeg ?
Cos my set-top box player does not support Constant Frame rate mode.
Thanks.
