this might seem rather obvious, but i haven't found any answer to this,
neither in any header-files nor in google. i have to admit that i didn't
try to read the code of mplayer or the like.
if this is the wrong list, please re-direct me. anyhow:
i am writing an application (pd/Gem) that uses ffmpeg to decode video. i
would like to know the frame-rate of an opened video-stream/file/whatever.
what is the correct way to do that ?
i found the "frame_rate" field in AVCodecContext, but it seems to be no
longer in use.
i also found the variable "pts" in AV_COMMON_FRAME which seems to be
related to this, but i am really unsure about this.
note: i am using debian (with christian marillats packages) and on 3
machines at home i have installed an avcodec.h with the 0x000409; all 3
files differ significantly (at least, regarding the frame_rate and
of course this is a problem with the debian-packages.
however i would like to know what is the advised way to get the
frame_rate in the future (eventually the debian-packages will be updated).
so is the API already fixated with this peculiar feature ?
(if not i will, for now, just _not_ try to read the framerate when using
