previously only codec_ids could be forced, which did not allow
forcing a specific implementation like libopenjpeg vs jpeg2000.

The caller does not expect this, and in case of adding new streams would then
not even be able to deallocate them anymore.

This reverts a hunk from "avformat: Use av_reallocp_array() where suitable"

The purpose of this commit is to make error management simpler and less
error prone, just like av_free() which is safe with NULL.

This ensures that no read timestamp functions finds packets before the search window in ff_find_last_ts()
which could cause an infinite loop

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

This avoids breaking some slightly incorrect (dts > pts) timestamps

This causes a race condition with VLC. Its plausible that other
applications also would have races with it and its just fixing a memleak when
the user application forgets to free the codec. It causes more
problems than it solves in its current form, thus the revert.
Better solutions are welcome

If either of the deltas is too large for the multiplications to
succeed, don't use this for setting the avg frame rate.

This is part of normal operation with some formats. A warning should
indicate that something is wrong, and the documentation for AV_LOG_WARNING
says: "Something somehow does not look correct."

Since this message is most likely useful for debugging only, raise the
log level accordingly.
