[FFmpeg-devel] Short last frame with movenc

Hi, I`m trying to encoded a prores movie into a mov container.
This works fine with
time_base.den = 24
time_base.num = 1
But if I try
time_base.den = 600
time_base.num = 25
I get problems with moveenc setting the duration of the last frame to 1,
instead of 25.
It looks like oformat->write_header() which is called in
avformat_write_header is setting the AVStream time_base to 600:1 instead
Can some one reproduce this, I did a packet dump and the durations are
all 0.0002, whereas using 24/1 they come out with the correct duration
Oddly the pts and dts values look right.
Any help would be much appreciated, the odd time_base values are for
Final Cut Pro (yeah right) compatability.
