mpegvideo: Avoid 32-bit wrapping of linesize multiplications
This is not merged as its not correct for ffmpeg and would introduce a
security issue if merged as is.

mem: Document the av_realloc family of functions properly
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This makes sure that linesize * start_y doesn't overflow, so that
emulated_edge_mc can get back the original value if needed.

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 d73cbc22c5
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
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
The code tries to decode a number of channels at the
offset given by the ff_alac_channel_layout_offsets table.
Even if the number of channels decoded so far doesn't
exceed the total number of channels, we need to check that
we actually can decode that number of channels at this offset
as well.

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.

Merged-by: Michael Niedermayer <michaelni@gmx.at>
The check added in df33a58e53 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

The added check is redundant.
It shows the error path more clearly though

This should improve write performance quite significantly.

Tested with both writing a normal mp4, by using the faststart
feature and writing a fragmented mp4 file; all turn out with the
same md5sum as before.
