[avi @ 01E5A600] Something went wrong during header parsing, I will ignore it an
d try to continue anyway.
[mpeg4 @ 01E5AB00] hmm, seems the headers are not complete, trying to guess time
_increment_bits
[mpeg4 @ 01E5AB00] my guess is 5 bits ;)

(issue 971)

Not all frames are decoded for this sample, was this better at any time?

[cehoyos]

Completely unrelated:
The binary decoder GeoCodec?.dll contains the following string:

This software is derived from the GNU GPL XviD codec (0.9.1).
Your software distributor has to give access to its source code.

Replying to cehoyos:

It always decoded like that if I remember correctly.

Attached patch leads to invalid memory accesses in emulated_edge_mc().
