The timeout parameters were not reinitialized.

This does _not_ fix #2322 (Qt4).

This reverts commit 3cda36f4.

and therefore freeing the memory only when the i_refcount successfully
went to 0.

The problem was that i_refcount is an unsigned variable, and was being
decremented twice, once erroneously by mosaic_bridge, and then again in
the picture's original pf_release function. If i_refcount started at 1,
it wrapped to the maximum unsigned value rather than -1, failing the
refcount tests in the pf_release function.

It seems to work, but I have difficulties to find a reference output.
Support for TrueHD is not yet tested because of lack of correct sample.

First step of fixing linking errors against libx264

contribs: don't compile ffmpeg with mdynamic-no-pic on PPC-Macs, as this is a really bad idea. You need PIC in shared libs on this platform.

This slows down the compilation speed by 5%, but that should be fine. Pointed by nobody.loopback on the forum.

It fixes #2648.

This removes a lot of false true positives.

It was based on xxcv investigation and preliminary patch.
It should fix #2644.

Always increase i_bytes_per_frame to avoid cycling between 2 values with
some files.

YES, imagine, including stdint.h is apparently a good idea from time to time!
