Adding to the answer: Using FFmpeg's parser and not Nvidia's can
help with unusual samples.

Unrelated:
The following have no effect, removing them makes debugging
easier:
--enable-asm --enable-yasm --disable-libopenjpeg --enable-decoder=tscc
(You cannot enable tscc with --disable-zlib)

Is there something about iconv that we should know?
Why are you disabling it?
