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 \

The option was added in commit d9ae1031f5
but it was never documented. The text is based on the one written by the
commit author for the corresponding AVFormatContext.max_interleave_delta
field.
Users have no means to find out from a failure how to make it work
or is it preferred to check and print a warning for h264 concat without auto_convert ?

This is useful for client programs to ask for nv12 surfaces instead of the

This partly undoes 7b35a01.
The intent of patch 7b35a01 was to no longer use build_date and
build_time as attributes of programVersion, but the patch also had the
effect of making all records generated with an earlier ffprobe build with
build_date and build_time as invalid.
This patch puts the two attributes back but without mandating their use,
thus older ffprobe records as backwards compatible with the current
schema and their use is no longer required.
