[Ffmpeg-devel] Hitting Assertion on mov.c line 1889

[Tom Hayden]

Good Morning All,

I'm somewhat new to ffmpeg and I think this is a solid peice of software.
However, I'm having some problems, namely hitting the assertion on
mov.cline 1889. I'm trying to convert 3gp files to flv and have ffmpeg
compiled
with these options: --enable-amr_nb --enable-amr_wb --enable-mp3lame
--enable-gpl --enable-amr_wb --enable-pp --enable-a52

When I comment out the assert() on line 1889 of mov.c then it converts my
video, however the time seems to be off since my video playback is at
roughly 75% of the original speed (both audio and video remain in sync). You
can find the videos below:

http://35.11.78.70/tom.flv
http://35.11.78.70/tom.3gp

I'd like to to just fix this myself (and contribute to the code), but I
guess I need a little background from one of the experts on what is going on
here.  I suspect this time_base.num is probably linked to the fact that my
videos are being encoded at a slower rate.

assert(pts % st->time_base.num == 0);
assert(dts % st->time_base.num == 0);

Yours,

Tom Hayden
