seekable mp4

jackyr
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
Jacky

Use -video_track_timescale

See tickets #2658 and #3251 which contains an
unanswered question that might allow to fix
the issue.

many thanks Carl
your fix does solve tbn issue but the mp4 is still not streamable
the tbc is twice the tbn this might be the problem ???

You will have to run "git bisect" to find out which
change introduced the problem.

I know it isn't very easy but I do it every other day
and I will guide you if you have questions.

At least one output file must be specified

theses two exemple are using the same source VOB file
command line
ffmpeg -i video_courte.vob   -f mp4 -c:v libx264   -s 720x576 -pix_fmt
yuv420p -crf 23  -video_track_timescale 25 -r:v 25  -an -movflags
faststart  -y video.mp4

Im am quite sure I used the almost same command line
(-video_track_timescale and -movflags )
does this help ?

thanks
jacky
