The value you give (4294967296) is not even close to -1, this is a 64 bit
value (otherwise files > 4 GB wouldn't be possible).
In addition, according to the code the value for "not set" should be 0,
not -1.
The code probably should take the file size into account when deciding
which to use, however it happens to pick the right one anyway.
As for decoding, it looks like somehow pix_fmt doesn't get set at the
right point.
The strange thing is that MPlayer works just fine.
It seems to me that somehow frame multithreading is enabled and that
breaks try_decode_frame.
