hello, good morning
I try to encode from PNG files a MP4 video for rtmp streaming by red5
software
it used to be ok in a past , with present ffmpeg version it is not any more
I am quite sure i miss some args . could you help me ?
- by the way, every thing is fine with flv container -f flv and .flv
extension
- same trouble with different profiles
- not streamable and not seekable (the red5 software does not generate
meta files)
_my command line is _
ffmpeg -r 100/900 -f image2 -i diapositive%%d.PNG -f mp4 -c:v
libx264 -s 720x576 -pix_fmt yuv420p -crf 20 -r:v 25 -an -movflags
faststart -y video.mp4
_
results _

the tbn result is 12800 it seems this value is the main problem (the
files encoded year_sss ago does have tbn 25)
is there any fixes , which mistake I am doing ?
thanks for your advices
