avcodec/aacdec: fix compilation under soft float MIPS
Place HAVE_MIPSFPU further up so that functions that use floating point
ASM are defined away. Otherwise compilation failures result when soft
float in enabled on the toolchain.
lavf/oggparsevorbis: Use case-insensitive key compare for vorbis picture
Regression since 8d3630c5402fdda2889fe4f74f7dcdd50ebca654 where keys were changed
to not be touppered but the picture block strcmp was not changed to be case-insensitive.
Font sizes are relative to the subtitle frame dimensions. If the
expected frame dimensions are not known, the font sizes will most
likely be incorrect.

h264_sei: parse the picture timing SEIs correctly
Those SEIs refer to the currently active SPS. However, since the SEI
NALUs precede the coded picture data in the bitstream, the active SPS is
in general not known when we are decoding the SEI.
Therefore, store the content of the picture timing SEIs and actually
parse it when the active SPS is known.

h264dec: do not abort if decoding extradata fails
Such errors are not necessarily fatal and decoding might still be
possible, e.g. it happens for MVC streams where we do not handle the
subset SPS thus failing to parse its corresponding PPS.

lavc: do not implicitly share the frame pool between threads
Currently the frame pool used by the default get_buffer2()
implementation is a single struct, allocated when opening the decoder.
A pointer to it is simply copied to each frame thread and we assume that
no thread attempts to modify it at an unexpected time. This is rather
fragile and potentially dangerous.
With this commit, the frame pool is made refcounted, with the reference
being propagated across threads along with other context variables. The
frame pool is now also immutable - when the stream parameters change we
drop the old reference and create a new one.

pthread_frame: merge the functionality for normal decoder init and init_thread_copy
The current design, where
- proper init is called for the first per-thread context
- first thread's private data is copied into private data for all the
other threads
- a "fixup" function is called for all the other threads to e.g.
allocate dynamically allocated data
is very fragile and hard to follow, so it is abandoned. Instead, the
same init function is used to init each per-thread context. Where
necessary, AVCodecInternal.is_copy can be used to differentiate between
the first thread and the other ones (e.g. for decoding the extradata
just once).
subtitles.h has been included in order to use ff_subtitles_next_line()
to help parsing srt subtitles which at that time had their timing as
part of the payload and not as part of the AVPacket fields. When this
changed (in 55180b32) it has been forgotten to remove this header.
libavcodec/internal.h meanwhile has been added in bb47aa5850c and has
never been used at all.

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.

This is mainly about improving legibility of the code and getting rid of
overlong lines by using variables for st->codecpar instead of accessing
the codecparameters via st->codecpar->.
Also, some code has been moved to better fitting places.

This commit removes data that is only used during smacker_read_header()
from the demuxer's context and replaces the data that is used by local
variables. The other data is completely dropped.
Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
The Smacker demuxer currently parses several fields that indicate
how many audio streams a file contains. This data is parsed and stored
into arrays in the demuxer's context and although the data is used only
to initialize the audio streams, it is kept for the whole lifetime of
the demuxer.
This has been changed: The data is used directly to create
the audio streams and no longer kept at all.
This also simplifies error handling in case adding a new stream fails:
Several arrays which until now have been allocated between parsing the
data determining how many audio streams to create and actually creating
them would need to be freed in this case. Now the streams are created
first, so freeing is no longer an issue.

avformat/smacker: Read extradata directly into extradata
The Smacker demuxer reads four consecutive 32bit values from the file
header into its demux context (as four uint32_t), converting it to
native endianness in the process and then writing these four values
later (after extradata has been allocated) to extradata as four 32bit
values (converting to little endian in the process).
This commit changes this: The stream and the extradata are allocated
earlier, so that the data destined for extradata can be read directly
into extradata.
Furthermore, given that these values are not needed for demuxing itself
they are now no longer kept as part of the demuxing context.
Finally, a check regarding the number of frames has been moved up,
too, in order to exit early before unnecessarily allocating the
stream and the extradata.

The WebM DASH Manifest muxer only supports VP8, VP9, Vorbis and Opus,
but there was no check for this. The codec type is used to get a pointer
to a string containing the codec name or NULL if it is not one of those
four codecs. Said pointer has then been used without further checks as
string for the %s conversion specifier in an avio_printf()) call which
is undefined behaviour.
This commit adds a check for the supported codec types.

Some broken apps generate files that have a fake box named 'hoov'
instead of a proper 'moov' one. This is speculation but it seems like
this box contains data to be modified later (eg as file grows in size,
data gets re-written) and its name is supposed to be changed to 'moov'
once it can be used as a 'moov', but for some reason this step is skipped.
Since this is not the first time this happens ('moov' boxes can be found
in 'free' ones) extend the existing hacks to search for the moov in such
boxes and skip the moov_retry since it needs to be found right away.
hwcontext_vulkan: only use one semaphore per image
The idea was to allow separate planes to be filtered independently, however,
in hindsight, literaly nothing uses separate per-plane semaphores and it
would only work when each plane is backed by separate device memory.
