This ensures that no read timestamp functions finds packets before the search window in ff_find_last_ts()
which could cause an infinite loop
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

This fixes an infinite loop
An alternative fix would be to revert d73cbc22
but that would worsen error resilience.

On openbsd the exif-image-jpg test fails but diff treats the files as
binary due to some non ascii symbols in them. This should force it to
treat them as text, which should result in more informative output

Otherwise buffer size calculations in allocate_buffers could
overflow later, making the code think a large enough buffer
actually was allocated.

Skip the "\r" as normal text. Otherwise it will be the first character
of the string passed to sscanf(), which then fill fail to match the
timestamps.

The check added in df33a58e does not work
at all, rather it broke the summing of bitrates completely.
The comparission was wrong way around.
This commit replaces it by a simpler and hopefully clearer check

An alternative to this would be to change the code to support any
stride.
The condition of differing strides should be rare.
If theres no speedloss supporting any stride would be better
