de8f6a4033 avformat/hlsenc: Fix memleak when deleting old segments
if the directory name of the segments contains "%v".

This memleak is caused by masking the pointer that will eventually
be freed by a variable of the same name in a smaller scope.
Therefore the pointer that gets freed is always NULL when it is
freed and the allocated data leaks.

8c3e9c9cbb avformat/hlsenc: fix default AES key file url with variant streams
Currently when hls_enc is active and there are multiple variant stream
outputs, default key file url construction does not work, because it is
based on the FormatContext' url field. But in case of multiple variant
streams, it contains the variant m3u8 output playlist url that contains
the %v placeholder. So the result key file url will hold the %v
placeholder causing run time error message about "could not write the
key file".
This patch correct this behaviour, and use the master playlist url for
constructing the output key file url when master playlist is vailable.

dd5c7378bb avformat/hlsenc: program_date_time and append_list flags conflict
When program_date_time flag is present, in m3u8 playlist file each
segment has a corresponding EXT-X-PROGRAM-DATE-TIME value. The intial
program-date-time value is the actual current time at init and
each new segment increments this value by its duration. When append_list
flags is also present, existing playlist parsing by hls_append_segment
treats existing segments as new segments regarding the program-date-time
calculation. But it should not do that, because this way all real the
new segments' EXT-X-PROGRAM-DATE-TIME values will be shifted erroneously
by the sum duration of existing segments. Instead it should have
decremented the initial program-date-time value by its duration. This
would ensure that
the first new segment's program-date-time value had the current time as
it is expected.
This patch corrects this behaviour and prevent existing segments to
increment the value of initial_prog_date_time variable but decrements
it.

5ba3a8958c avformat/hlsenc: Fix memleaks with repeating parameters
When a parameter like e.g. language is contained more than once in the
part of var_stream_map pertaining to a single VariantStream, the later
one just overwrites the pointer to the earlier one, leading to a
memleak. This commit changes this by handling the situation gracefully:
The earlier string is silently freed first, so that the last one wins.

149ee954a3 avformat/hlsenc: Fix potential segfault upon allocation failure
The hls muxer allocates an array of VariantStreams, a structure that
contains pointers to objects that need to be freed on their own. This
means that the number of allocated VariantStreams needs to be correct
when they are freed; yet the number of VariantStreams is set in
update_variant_stream_info() resp. parse_variant_stream_mapstring()
before the allocation has been checked for success, so that upon error
an attempt would be made to free the objects whose pointers are
positioned at position NULL (the location of VariantStreams) +
offsetof(VariantStream, the corresponding pointer).

Furthermore d1fe1344 added another possibility for the first function
to leave an inconsistent state behind: If an allocation of one of the
objects referenced by the VariantStream fails, the VariantStream will be
freed, but the number of allocated VariantStreams isn't reset, leading
to the same problem as above. (This was done in the mistaken belief that
the VariantStreams array would leak otherwise.)

Essentially the same also happens for the number of cc-streams. It has
been fixed, too.

bd131b64bc avformat/hlsenc: Fix leak of options when writing packets
Under certain circumstances hls_write_packet() would add options to an
AVDictionary. Said dictionary was never explicitly freed, instead it was
presumed that these options would be consumed when opening a new
IO-context. This left several possibilities for memleaks:

a) When no new IO-context would be opened at all. This is possible when
using both the flags temp_file and single_file together with a file
output.
b) When an error happens before one actually tries to open the new
IO-context.
c) When the new IO-context does not consume all options.

All three have been fixed; furthermore, the AVDictionary has been put
into a smaller scope (namely the only part of hls_write_packet() where
it is actually used).

9e4b3ccbb6 avformat/hlsenc: Fix leak of options when initializing muxing fails
hls_mux_init() currently leaks an AVDictionary if opening a dynamic
buffer fails or if avformat_init_output fails. This has been fixed by
moving the initialization resp. the freeing of the dictionary around:
In the former case to a place after opening the dynamic buffer, in the
latter to a place before the check for initialization failure so that it
is done unconditionally.

Furthermore, the dictionary is now only copied and freed if the options
in it are actually used (namely when in SEGMENT_TYPE_FMP4 mode).

Finally, a similar situation in hls_start() has been fixed, too.
