FFMpeg Exr Encoder

Matthew.Alexander - The Empire Post
Hi,


I've been trying to use ffmpeg to speed up processes here at work, however it has come to my attention that ffmpeg does not have an encoder for exr, all I want to do right now is take existing EXRs and half the resolution, however this doesn't seem to work.


Any tips?


The Code i'm using:

ffmpeg -i JumbleFalls_419_C001_Reverse_bg_FinalImage.%4d.exr -c:v copy -s 0x0 test.%4d.exr


Regards,
Matthew.

Don't use ffmpeg, but use OpenImageIO (oiio) or ImageMagick.
If you don't find binaries around, you can check out my viewer (mrViewer
with binary releases at sourceforge) that comes with a copy of oiiotool
and ImageMagick's convert.

That is very pointless command.

FFmpeg doesn't have an exr encoder yet.
The most difficult part, is to add float/half pixel format in ffmpeg,
before adding an exr encoder.
(for now ffmpeg exr decoder, decode data in 16bit (int) not in float)
