Boy, its screwey with all the latest version but I got it working again
after pulling teeth through all the bugs.
If your getting the -hu problem with ffmpeg, update you nuvexport from
trunk and that should go away. After you've done that, try to re-encode
again to see if it works. Otherwise continue on.
If you get a file that looks kind of like it completed but it won't
play. (aka, not the .temp.mp4 file but the full .mp4 file) You must have
a new version of ffmpeg that isn't reporting FFMPEG_VERSION. So you get
to rebuild gpac.
Install GPAC 0.4.2
tar -zxf gpac-0.4.2-rc2.tar.gz
tar -zxf gpac_extra_libs-0.4.0.tar.gz
cp -r * ../gpac/extra_lib
Modify line 662 of gpac/modules/ffmpeg_in/ffmpeg_decode.c with this line
(or get CVS version of gpac and skip modifying the code on your own)
sprintf(szCodec, "FFMPEG %s", ffd->codec->name ? ffd->codec->name :
chmod +x configure
From here, it worked for me. Not fun but once it works, they are
crystal clear transcodes from a push of a button.
note: I am still using his modified version of ipod.pm from nuvexport too.
