Hi again,
I think I now have a stable build, by pulling the following revisions
from svn://svn.ffmpeg.org/ffmpeg/trunk:
r18332
r18333
r18535
r18600
r18601
r18712
r18713
r18916
r18917
r18972
r19216
r19308
r19345
The attached patch enables the NEON build flavour and applicable build
options in debian/confflags. The patch is against the karmic source,
but the upstream Debian source is not much different.
To within that difference, I've succesfully built the upstream source
package and the karmic package, and they seem to work OK, with a decent
improvement in video decode speed for H.264 (I haven't tested
exhaustively).
** Attachment added: "Patch against karmic ffmpeg-debian source to enable neon build flavour and relevant compiler options"
