Calling ffio_ensure_seekback() if ffio_init_checksum() has been called
on the same context can lead to out of bounds memory accesses and
crashes. The reason is that ffio_ensure_seekback() does not update
checksum_ptr after reallocating the buffer, resulting in a dangling
pointer.

This effectively fixes potential crashes when opening mp3 files.

We are missing the handling of some special cases for this.
These cases should be unused and there should be no reason

The current check is too strict for newer makeinfo versions.
Existing version strings are:
makeinfo (GNU texinfo) 4.13
makeinfo (GNU texinfo) 5.2
texi2any (GNU texinfo) 5.9.93

Probably version 6 will come in the not too far future.

In the TTA extradata re-construction the values are written with
avio_wl16 and if they don't fit into uint16_t, this triggers an
av_assert2 in avio_w8.

And default to 8000 if it is invalid.

An invalid sample rate can trigger av_assert2 in av_rescale_rnd.

Fixes ticket #4628.

The problem arose, in the sample file at least, in the last block where the
minimum and maximum Rice partition orders were both 0. In that case, and any
other where pmax == pmin, the original UINT32_MAX placeholder value for
bits[opt_porder] was getting overwritten before the comparison to check if the
current partition order is a new optimal, so the correct partition order and
RiceContext params were not being set.

907ac20a avformat/hlsenc: added HLS encryption
Signed-off-by: James Zern <jzern@google.com>
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Added HLS encryption with -hls_key_info_file <key_info_file> option. The
first line of key_info_file specifies the key URI written to the
playlist. The key URL is used to access the encryption key during
playback. The second line specifies the path to the key file used to
obtain the key during the encryption process. The key file is read as a
single packed array of 16 octets in binary format. The optional third
line specifies the initialization vector (IV) as a hexadecimal string to
be used instead of the segment sequence number (default) for encryption.
Changes to key_info_file will result in segment encryption with the new
key/IV and an entry in the playlist for the new key URI/IV.

Key info file format:
<key URI>
<key file path>
<IV> (optional)

Example key URIs:
http://server/file.key
/path/to/file.key
file.key

Example key file paths:
file.key
/path/to/file.key

Example IV:
0123456789ABCDEF0123456789ABCDEF

Example:
ffmpeg -f lavfi -i testsrc -c:v h264 -hls_key_info_file file.keyinfo
foo.m3u8

file.keyinfo:
http://server/file.key
/path/to/file.key
0123456789ABCDEF0123456789ABCDEF

Example shell script:
BASE_URL=${1:-'.'}
openssl rand 16 > file.key
echo $BASE_URL/file.key > file.keyinfo
echo file.key >> file.keyinfo
echo $(openssl rand -hex 16) >> file.keyinfo
ffmpeg -f lavfi -re -i testsrc -c:v h264 -hls_flags delete_segments \
