I've been asked to package ffmpeg inside an Adobe AIR application. The
Adobe documentation says that this can be done by compiling the app (ffmepg
in this case) as a .dll (for windows) and a .framework(for mac). I'll need
to do both.
So my question is, how hard is going to be to change the make
I need to package the ffmpeg's .dll into another application and call it
directly.
>From the command line, the command need to provide would be:
*ffmpeg -i test.avi -f image2 foo-%03d.jpeg*
But I'm not sure which .dll file I need to include, nor which top-level
function I should be calling.

I'm using ffmpeg to extract a series of jpgs from an avi. Is it possible
to have ffmpeg pull the audio down along with it, so that I have that as an
audio only track? I read the docs but it wasn't entirely clear how to do
this.
Thanks!

Thanks again!

I'm having some strange behavior if I try to do the following:
ffmpeg -f image2 -r 60 -i /input-%02.png -i /input.wav out.mov
The first few secounds of video are black and then it almost fades in with
the black and white being messed up and almost looking like they went
through a Gaussian filter.
Sorry for all the newbie questions, I'm doing my best and spending lots of
time working at it before I mail the list. :)
given two one-second sounds I'm trying to concatenate them using several
approaches. None of them seem to be working:
Using -itsoffset
>*ffmpeg -i beep-1.mp3 -itsoffset 00:
I should add that if I -map 0:0 -map 1:0 it seems to merge them, but still
no -itsoffset on the 2nd one.

et the audio to show up at specific offsets.
Is there a way to use -itsoffset in conjunction with concat: ?

I'm having some problems getting ffmpeg to behave the same on windows as
opposed to mac. Mac seems to have some codec problems, where the windows
version is fine. Here is my output:
Any help understanding why my mac version is failing would be appreciated.
Thanks!
*Mac*:
./ffmpeg -i test.AVI
So is there a way to get ffmpeg.dmg to use the correct codec without
rebuilding it from source?

Stream mapping:
Stream #0:0 -> #0:0 (mjpeg -> mpeg4)
Stream #0:1 -> #0:1 (pcm_u8 -> libaacplus)
Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height
