This option is extremely codec specific and only a few codecs employ it.
Move it to codec private options instead: mpegenc family supports only 3

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

file.keyinfo:

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.

This is necessary, because avcodec_decode_video2 can change
width, height and/or pixel format of the AVCodecContext. Since
video_dst_data and video_dst_linesize are not updated by calling
av_image_alloc again, av_image_copy[_plane] asserts, because the
destination buffer is too small.
In this case, creating a useable rawvideo is not possible anyway, since
it has fixed width/height/pix_fmt.

This adds an option to set the service type in mpegts as defined in ETSI 300 468.
I added what I believe are the most useful service types as pre defined values,
the others can be sent by using their hexdecimal form directly (e.g. -mpegts_service_type digital_radio, -mpegts_service_type 0x07).
I've been using this patch in order to pipe internet radio stream (originally as HLS/m3u8) from ffmpeg to tvheadend,
when the service type set right tvheadend recognize the mpegts stream as a radio channel.
The patch in its original form was written by linuxstb from freenode's hts channel which allowed me pushing it upstream.

The new functions have an align parameter, which allows to define the
