Hi
Sorry, but I missed that Windows is a center of your question. I'm not
on Windows at all so i can't help... :(
But generally: ffmpegWriter and Reader in Nuke (and the sources
included in NDK) are based on very old ffmpeg libraries and on an old
API. You cannot compile it against current ffmpeg libraries. The code
have to be modify.
But even than keep in mind, that those plugins's implementation in
Nuke is quite limited and very simplified. There is no acces to
advanced codecs settings, no timecode support, no audio support, no
respects for colorspaces, support for 8 bit RGB pixel format only etc,
etc. To bring full functionality of modern ffmpeg libraries into the
Nuke, those plugins have to be developed almost from scratch. To do
that you need to be familiar not only with C/CPP language but also
with ffmpeg API, altogether with it's weirdness and traps. I did it
for ffmpegReader but not for Writer yet. It's on my long "to do" list.

Hey Jimmy,
There is ProRes support in ffmpeg.

Would be really nice if Foundry would precompile the
ffmpegwriter for Windows and with an updated libavcodec. Then
we would have ProRes support in Windows too :)

At the time of that comment (2008 or 2009). It wasn't that
the Foundry
didn't have access to x64 version of Windows. The issue
was that at
that time the ffmpeg source code was only 32 bit and they
hadn't created
a 64 bit version yet.

Hey,
Thanks Adrian. Although this didn't quiet answer my
post, I
appreciate your feedback. What I'm blatantly asking
the Community is,
if you've successfully compiled the Nuke supplied
ffmpegWriter and or
ffmpegReader or any variation of this code and it's
working on
Windows7 Pro in Nuke6.3v+ and your interaction with
the compiled
plugin via Nuke's Write node looks like the screen
grab Jimmy so
kindly offered up, then "How did you accomplish this?".
I'm told that I could install Visual Studio 2005 Win7
SP1 and the
update for Vista/Win7, but I'm no C programmer and I'd
really hate to
waste more time thinking, by installing this and
compiling, I'm all
set. I've read over and over on others multiple
attempts at compiling
this on Windows and it not working. Although I have
read that
compiling on Linux is easy peasy and the ones who are
fortunate enough
to be on Linux also get this pre-compiled for use. The
foundry's
excuse for Windows is that they don't have access to
Windows x64 (only
32) which leads me to think, how the hell did they
compile Nuke6.3v7
64bit? Hmmm, maybe that was an old posting from Matt
at the Foundry (
sorry Matt ). Again, I'm not a C programmer so if I
sound like I
don't know what I'm talkin about, there's my excuse.
This isn't something proprietary, the code is there!
All I'm
searching for are the steps, compilers used, things to
watch out for,
etc... One would think with the amount of data on the
internet,
someone somewhere would have posted something.
Sorry for coming off a bit terse but I've been
researching this a
little to long now.
Thanks,
Dan

Hi
We need to creates tons of previews and send them to
clients. So I
wrote mpeg writer based on ffmpeg libraries and we are
using it
all the time. It is preseted for instance to create
"mail-mpeg
with audio" so artists don't need to worry about any
format
settings; just create mail-mpegWriter, set output
path, choice
audio file and click render- don't care about anything
else.
From my practice it's much better to have separate
writers for
different formats. I strongly recommend this way even
if your
plugins's code is almost the same. It's better and in
the long
term even simpler than multi-format writer.

Hi all,
Wanted to know if anyone has compiled the ffmpegWriter
and if
so, do you have type of info on how you're using it?
Like, if
the plugin is selected in a Write node, what type of
attributes are associated? Does it function like the
"advanced settings" for movie formats, etc...
If you have successfully compiled this and you're
using it,
would love to get a few screen grabs too.
Wanting to see how it's implemented before delving
into it and
possibly extending it.
Thanks much!!!
