If the metadata packet is corrupted, flv_read_metabody can accidentally
read past the start of the next packet. If the start of the next packet
had been flushed out of the IO buffer, we would be unable to seek to
the right position (on a nonseekable stream).
Prefer to clearly error out instead of silently trying to read from a
desynced stream which will only be interpreted as garbage.

We currently only have exported data symbols within libavcodec, but
the concept is easy to extend to other libraries if necessary.
The attribute declaration needs to be in a private header though,
since we can't use CONFIG_SHARED in public installed headers.

Hi, it fixes the errors while converting to framesync2.
libvmaf was changed recently, double *score variable is removed in the new
version since it's not used anywhere. This patch fixes all the warnings and
segmentation faults.

The use of this SEI is for backward compatibility in HLG HDR systems:
older devices that cannot interpret the "arib-std-b67" transfer will
get the compatible transfer (usually bt709 or bt2020) from the VUI,
while newer devices that can interpret HDR will read the SEI and use
its value instead.

glibc introduced _DEFAULT_SOURCE in version 2.19 to replace _BSD_SOURCE and
_SVID_SOURCE, which were deprecated in version 2.20. Add _DEFAULT_SOURCE
where the latter two are used to be forwards-compatible and avoid warnings
about the use of deprecated definitions.
